Application to add oxycodone to the

Essential Medicines List for Children

Summary statement of the proposal for inclusion Pain in children is a public health concern of major significance in most parts of the

world. Although the means and knowledge to relieve pain exists, children’s pain is often not

recognized, is ignored, or even denied. It is important that adequate access to appropriate

opioid medicines be available for the treatment of moderate to severe persisting pain in

children worldwide.

To align the Essential Medicine List for Children (EMLc) with the recently published

WHO guidelines on the pharmacological treatment of persisting pain in children with medical

illnesses [WHO pediatric pain guidelines, 2012: p.78– further referred to as “Guidelines”], it

is necessary to add more opioid preparations to the EMLc. The Guidelines state that if pain

severity associated with a medical illness is assessed as moderate or severe, the

administration of a strong opioid is necessary. In that case morphine is the medicine of choice,

although other strong opioids should be considered and made available to ensure an

alternative to morphine in case of intolerable side-effects. It is advised that two or more

strong opioids should be available for this purpose, and oxycodone is one such strong opioid.

Thus, it is requested that oxycodone be added to the EMLc as an example of the opioid class.

Accordingly, it is necessary to add the oxycodone monograph in the Model Formulary in

accordance to the aforementioned Guidelines.

With this application, we request:

1. Addition of oxycodone preparations as an example of the opioid class to the EMLc.1

2. Addition of a monograph on oxycodone in the WHO Formulary for children

This application is part of a series of three applications:

- Application to add certain morphine formulations to the Essential Medicines List for

Children;

- Application to add oxycodone to the Essential Medicines List for Children; and

- Application to add hydromorphone to the Essential Medicines List for Children.

Formulations proposed for inclusion, including a proposal for a monograph in the WHO Model Formulary for children

Preparations to be added to the EMLc

In order to provide adequate pain treatment for persisting pain in children, it is

required that the following formulations of oxycodone be added to the Essential Medicine

List for Children, under section 2.2 Opioid Analgesics:

a. Tablet: 5 mg, 10 mg, 15 mg, 20 mg, 30 mg (as hydrochloride)

b. Tablet (slow-release): 5 mg, 10 mg, 15 mg, 20 mg, 30 mg, 40 mg, 60 mg, 80

mg,160 mg (as hydrochloride)

c. Capsule: 5 mg, 10 mg, 20 mg (as hydrochloride)

d. Oral liquid: 1 mg/ml, 10 mg/ml, 20 mg/ml (as hydrochloride)

These preparations should be equally added to the palliative care section of the EMLc.

Rationale for these strengths and dosage forms

Introduction

The WHO Guidelines on the Pharmacological Treatment of Persisting Pain in

Children with Medical Illnesses identify four key concepts for the correct use of analgesic

medicines and three of these concepts affect the need and selection for oxycodone

preparations [Guidelines, 2012: pages 38–40]:

• dosing at regular intervals (“by the clock”)

• using the appropriate route of administration (“by the mouth”)

• tailoring treatment to the individual child (“by the individual”).

The WHO Guidelines on the Pharmacological Treatment of Persisting Pain in

Children strongly recommend switching opioids (and/or route of administration) in children

in the presence of inadequate analgesic effect with intolerable side-effects. [Guidelines, 2012:

Guidelines 10, p. 44] and alternative opioids and/or dosage forms as an alternative to oral

morphine should be available to practitioners, in addition to morphine, if possible.

[Guidelines, 2012: Guidelines 11, p. 44; both slow-release and immediate-release

preparations should be available [Guidelines, 2012: Guideline 8, p. 43; Guideline 9, p. 43 ];

and oral administration of opioids is the recommended route of administration. [Guidelines,

2012: Guideline 13, p. 45]. Therefore, the availability of a full range of preparations is

essential.

Need for a range of strengths of immediate release tablets or capsules

To obtain a dose that provides adequate relief of pain with an acceptable degree of side-

effects the doses of oxycodone or other strong opioids need to be gradually increased until

effective. Unlike paracetamol and NSAIDs, there is no upper dosage limit for opioid

analgesics because there is no "ceiling" analgesic effect. The appropriate dose is the dose

that produces pain relief for the individual child. The goal of titration to pain relief is to

select a dose that prevents the child from experiencing pain between two doses using the

lowest effective dose. This is best achieved by frequent assessment of the child’s pain relief

response and adjusting the analgesic doses as necessary.

The opioid dose that effectively relieves pain varies widely between children, and in the

same child at different times, and should, therefore, be based on the child's pain severity

assessment. Large opioid doses given at frequent intervals may be necessary to control pain

in some children; these doses may be regarded as appropriate, provided that the side-effects

are minimal or can be managed with other medicines. Therefore, a range of strengths of

oxycodone, as an example of an alternative to morphine, should be added to the EMLc.

[WHO guidelines, p.47]

Need for slow release formulations

Access to multiple strengths of slow-release oxycodone is essential for the treatment of

moderate to severe persisting pain in children as slow-release morphine allow for longer dose

intervals, and this improves the patient’s compliance by reducing dose frequency.

Need for liquid formulations

The oral administration is the preferred route of administration. Older children may be

able to swallow regular or slow-release oxycodone tablets/capsules, but young children and

infants may only be able to use liquid formulations of oxycodone.

Relation to the application for hydromorphone

For patients who do not react well to morphine, the guidelines require that two or

more alternatives to morphine are available. While morphine has a very wide range of

preparations for both oral and parenteral administration and for immediate-release and slow-

release, this is not the case for all other strong opioids. Therefore, oxycodon and

hydromorphone were selected as together they have a wider range of administration forms

readily available: injections, tablets, slow-release tablets, capsules and oral liquid are all

covered by this selection.

Why other strong opioids from the guidelines are not selected to serve as the example of a the

class of strong opioids alternative to morphine

Fentanyl: fentanyl may be expensive in some countries and lozenges may be suitable

for breakthrough pain, but less suitable for titrating. Therefore, the range of dosage forms as a

whole may be less suitable than for oxycodone and hydromorphone.

Methadone: the long half-life of methadone makes it more difficult to dose.

International availability - sources, manufacturers and trade names Oxycodone hydrochloride as a starting material is out of patent. Oxycodon tablets, slow-

release tablets, capsules, injections, oral solution and concentrate for oral solution are

available for purchase in a number of countries.

Whether listing is requested as an individual medicine or as an example of

a therapeutic group Listing is requested as an example of a therapeutic group. According to the Guidelines,

“alternative opioids” (i.e. two or more alternatives) to morphine should be available and this

should be expressed in the EMLc, for example as a footnote to the square box. [Guidelines,

2012: p. 44] The footnote could read “Examples for alternative opioids for morphine. Two or

more alternatives should be available in addition to morphine.”

Information supporting the public health relevance From a public-health perspective, currently many patients are without access to

essential medicines for pain. WHO policies recommend, and international drug conventions

require that countries make medicines controlled under these conventions readily available to

those in need. Opioid analgesics like morphine, hydrocodone and oxycodone are among these

controlled medicines.

The World Health Organization has a policy to promote the availability of strong

opioids in countries whose policies or legislation unduly does not allow access or availability

to strong opioids [Ensuring Balance, p.5]. Inclusion in the EMLc is essential for enhancing

this policy.

It has been well documented that in most countries of the world, patients do not have

adequate access to opioid analgesics. The various barriers are described in the World

Medicines Report [Milani B and Scholten W, 2011] and in the WHO policy guidelines

Ensuring Balance in National Policies on Controlled Substances, Accessibility and

Availability of Controlled Medicines. [Ensuring balance, 2011: p.5] Legal and policy barriers

are important reasons why these medicines are not available in many countries. Seya et al.

estimate that in 2006 only 464 million people had adequate access to opioid analgesics, and

4.7 billion people had virtually no access [Seya et al, 2011].

The World Health Assembly in its resolution 58.22 “On Cancer prevention and

control” (2005), called on WHO to address access to opioid analgesics [Resolution WHA

58.22, 2005]. Other international bodies such as the International Narcotics Control Board

(e.g. in a special report on the availability of internationally controlled drugs) [Report of the

INCB, 2011] and the UN Commission on Narcotic Drugs, have called for greater access for

patients to these medicines.

In addition, the International Association for the Study of Pain adopted the

Declaration of Montreal, the Union for International Cancer Control published the World

Cancer Declaration and a consortium of 60 international and national organizations initiated

by Pallium India launched the Morphine Manifesto. [Declaration of Montreal, 2011; World

Cancer Declaration, 2006; a Morphine Manifesto, 2012] All these declarations call for

adequate access to pain medicines and treatment of pain worldwide.


12

Treatment details The treatment recommended by the World Health Organization is published in the

WHO Guidelines on the Pharmacological Treatment of Persisting Pain in Children with

Medical Illnesses. These guidelines address the pharmacological management of persisting

pain in children with medical illnesses. As such, they replace the previous guidelines, Cancer

pain relief and palliative care in children, which exclusively covered cancer pain. [Guidelines,

2012: p. 10]. Treatment details in this application are based on the Guidelines on the

Pharmacological Treatment of Persisting Pain in Children.

For the treatment of pain, no special diagnostics are needed, nor any technical

monitoring facilities. Although in certain stages of treatment monitoring of the patient is

necessary, this refers to clinical monitoring which could include phone calls or home visits to

check on progress, dose tracking, or pulse oximetry and respiratory monitoring in hospital,

depending on circumstances. In (very) rare circumstances it might include urine drug testing.

The treatment of pain requires to be preceded by and go together with a regular

assessment of the pain with simple pain scales, such as the FPS-R scales. Methods are

described in Chapter 2, Evaluation of persisting pain in the paediatric population, of the

guidelines. [Guidelines, 2012: p. 26-35]

Treatment recommendations

Dosage:

Starting dose for opioid-naive patients:

Oral (immediate-release formulation):

infant 1–12 months – 50–125 mcg/kg every 4 hours;

child 1–12 years – 125–200 mcg/kg every 4 hours, max 5 mg.

Oral (slow-release formulation):

child over 8 years – 5 mg every 12 hours.

Continuation: after a starting dose according to the dosages above, the dosage should be

adjusted to the level that is effective (with no maximum), but the maximum dosage increase

is 50% per 24 hours in outpatient settings. Experienced prescribers can increase up to 100%

with careful monitoring of the patient.

Dose for breakthrough pain

Oral (using immediate-release preparation):

infant or child: Additional oxycodone may be administered as frequently as required

with a maximum of 5–10% of the regular daily baseline oxycodone dose. If repeated

breakthrough doses are required, adjust the regular baseline oxycodone dose guided by

the amount of oxycodone required for breakthrough pain with a maximum increase of

50% per 24 hours.


13

The WHO guidelines on the pharmacological treatment of persisting pain in children

are evidenced based guidelines, produced using the methods prescribed actually for WHO

treatment guidelines. Oxycodone is considered an example of a strong opioid, as an alternative to

morphine, for moderate to severe persisting pain in children. Two or more alternatives to morphine

should be available and this should be expressed in the EMLc, for example as a footnote to the square

box.

According to the WHO guidelines on the pharmacological treatment of persisting pain

in children with medical illnesses, the immediate release oxycodone is initially dosed at 50–

125 mcg/kg every 4 hours for infants aged 1–12 months, and 125–200 mcg/kg every 4 hours

(max 5 mg) for children aged 1 – 12 years. The oral slow-release formulation is dosed 5 mg

every 12 hours for children over 8 years of age. After the appropriate starting dose, the

dosage should be adjusted on an individual basis to the level that it is effective (with no

maximum dose, unless further increase is not possible because of untreatable side-effects).

The maximum dosage increase is 50% per 24 hours in outpatient settings. Experienced

prescribers can increase up to 100% while monitoring the patient carefully. Common adverse

effects of oxycodone include nausea, vomiting, constipation, lightheadedness, drowsiness,

dizziness, sedation, sweating, dysphoria, euphoria, dry mouth, anorexia, spasm of urinary and

biliary tract, pruritus, rash, sweating, palpitation, bradycardia, postural hypotension, and

miosis. Uncommon adverse effects include respiratory depression (dose-related), tachycardia,

and palpitations. Rare adverse effects include syndrome of inappropriate anti-diuretic

hormone secretion (SIADH) and anaphylaxis. However, if titrated correctly, most side

effects can be avoided.

Opioid weaning can be done safely without posing significant health risk to the

patient. From the medical standpoint, weaning opioids should be done slowly by tapering the

opioid dose. For short-term therapy (7–14 days), the original dose can be decreased by 10–20%

of the original dose every 8 hours, increasing gradually the time interval. In the case of a

long-term therapy protocol, the dose should be reduced not more than 10-20% per week.

These pharmacological approaches should be accompanied by measurement of withdrawal

symptoms using a scoring system [WHO guidelines, 2012: p.47].

The Guidelines Development Group on the WHO guidelines on the pharmacological

treatment of persisting pain in children considered the lack of instruction on how to titrate

and how to wean patients on opioids a hazard. Therefore this information is considered

essential for the Formulary monograph. There is a need for comparative trials of opioids in

terms of effectiveness, side-effects and feasibility of use in children with persisting pain due

to medical illnesses.

It should be mentioned that the initial dosage is lower than often recommended

elsewhere [British National Formulary for Children, 2011: p. 256; Scholten W, 2012]. The

experts considered dosages recommended elsewhere as not deprived of risk. Also the lack of

instruction on how to titrate and how to wean patients on opioids is considered a hazard.

Therefore this information is considered essential for the Formulary monograph. There is a


14

need for comparative trials of opioids in terms of effectiveness, side-effects and feasibility of

use in children with persisting pain due to medical illnesses.

Summary of comparative effectiveness in a variety of clinical settings The guidelines provide the evidence for its recommendations in a number of GRADE

tables [WHO guidelines, 2012: p.104 ] and the further justification for each recommendation

is provided in an annex [WHO guidelines, 2012: p.82]. The guidelines also concluded that

more research is needed in order to answer specific questions. The guidelines are based on

the best knowledge currently available. See Annex 1 and 2 of the application for detailed

information regarding the recommendations in the guidelines. Annex 1 contains GRADE

tables regarding oxycodone and Annex 2 contains background information for the

recommendations. (Please also refer to the GRADE Tables in the parallel applications on

morphine and hydrocodone preparations.)

For clinical data please refer to Annexes 1 and 2.

Summary of comparative evidence on safety 1. Estimate of total patient exposure to date Oxycodon has been used as an analgesic since 1939. Since, it has been used in

innumerous patients and it has been shown to be a safe medicine if used correctly. In 2006

the world used 42.6 tonnes oxycodone, corresponding to 568 million DDDs. [Seya et al.,

unpublished data] The annual consumption by country can be roughly derived from the status

of estimates as published by the International Narcotics Control Board at

http://www.incb.org/incb/narcotic_drugs_estimates.html.

2. Description of adverse effects/reactions Adverse effects:

common – nausea, vomiting, constipation, dry mouth, sedation, biliary spasm,

respiratory depression, muscle rigidity, apnoea, myoclonic movements, asthenia,

dizziness, confusion, dysphoria, euphoria, lightheadedness, pruritus, rash, somnolence,

sweating;

uncommon – hypotension, hypertension, bradycardia, tachycardia, palpitation,

oedema, postural hypotension, miosis, visual disturbances, abdominal cramps,

anorexia, paraesthesia, malaise, agitation, tremor, muscle weakness, hallucinations,

vertigo, mood changes, dependence, drowsiness, anxiety, sleep disturbances,

headache, taste disturbance, agitation, urinary retention, laryngospasm, bronchospasm;

rare – circulatory depression, cardiac arrest, respiratory arrest, shock, paralytic ileus,

seizures.

Interactions with other medicines:

central nervous system depressants – additive or potentiating effects with

hydromorphone;

ethanol* – additive or potentiating effects with hydromorphone, potential fatal

interaction (dose dumping) if used with extended-release hydromorphone preparations;

monoamine oxidase inhibitors* – severe and unpredictable potentiation of opioids;

naloxone* – precipitates opioid withdrawal symptoms;

http://www.incb.org/incb/narcotic_drugs_estimates.html


15

naltrexone* – precipitates opioid withdrawal symptoms;

opioid antagonists/partial agonists* – may precipitate opioid withdrawal symptoms.

* Indicates severe.

3. Identification of variation in safety due to health systems and patient factors Inter-individual differences exist. Like for other opioid analgesics, the dosage level for

oxycodone needs to be established on an individual base [WHO guidelines, 2012: p. 37],

guided by the outcome of regular pain assessment. Provided that oxycodone is prescribed

when indicated, and titrated and weaned according to the guidelines, it has shown to be a safe

medicine.

Development of dependence on medical treatment is not well documented and it is

assumed that the risk is very limited [Noble, 2008; Minozzi, submitted] and this risk is not a

reason not to treat when indicated.[Minozzi, submitted] On theoretical grounds, it is likely

that pain patients are less susceptible to opioid dependence than other people. [Niikura, 2010]

There are well-described problems with over-prescribing and diversion in a limited

number of countries, although these studies are related to prescription to adults and not to

children. Non-medical use carries substantial risks, including overdose and mortality. It

should be noted that the extensively reported increase in consumption in the United States has

been accompanied by a notable increase in overdose deaths involving prescription opioids

[CDC,2011; CDC, 2012]. While there are insufficient data available to quantify the amounts

diverted to non-medical use from various parts of the drug distribution system, it appears

there is significant theft, fraud and other unlawful conduct [Inciardi JA et al. 2006a; Inciardi

JA et al., 2006b]. A national population-based survey in the United States found that over 70%

of those who have reported using opioids non-medically admitted that they obtained the drug

for free from friends or family members or through theft or purchase [SAMSHA, 2011].

Large quantities of prescription opioids have been sold by illegitimate pain clinics and

overdose has occurred predominantly in persons obtaining opioids from non-medical sources

[CDC, 2011]. In a study of unintentional overdose fatalities in West Virginia, 63.1% of the

decedents had used pharmaceuticals with no documented prescriptions, and 55.6% of the

decedents were never prescribed opioid analgesics. In addition, 79.3% of the decedents has

used multiple substances, both illicit and prescription drugs (“polydrug use”), which might

have contributed to their death, and 21.4 % of the decedents had controlled medicines

prescribed by multiple physicians (“doctor shopping”) [Hall AJ et al., 2008]. This study did

not determine, however, whether decedents from the latter group were ‘real’ pain patients, or

people seeking drugs for illicit purposes. Another American study, describing 9940 cases of

overdose deaths, found 51 cases to whom dosages of 100 mg/day or higher of morphine

equivalents were prescribed during the first three months of a prescription episode, showing

an increased risk for this group [Dunn KM et al., 2010].

In conclusion, although there is no doubt that some, albeit unknown, level of opioid

agonist prescribing and dispensing to pain patients contributes to morbidity and mortality in

the USA, many if not most of these tragedies appear to involve opioids that have been

diverted or obtained through unlawful activities, including those of non-patients.

4. Summary of comparative safety against comparators Opioids are the only class of medicines effective for moderate and severe pain, and

therefore, there are no comparators outside the class. Within the class of opioid analgesics,

there are no outspoken differences in safety with the exception of methadone, because of its

kinetics.

Summary of available data on comparative cost and cost-effectiveness

within the pharmacological class or therapeutic group 1. Range of costs of the proposed medicine The cost of slow release tablets 20 mg tablets in Switzerland ranges from Sfr 2.19 - 2.56

per tablet (USD 2.36 – 2.74 ); for all SR tablet strengths the range is Sfr 2.84 – 8.51 (USD

3.25 – 9.11) per 30 mg oxycodon. The cost of immediate release capsules 5mg ranges from

Sfr 0,80 - 1,14 per capsule (USD 0.85 – 1.22); for all strengths of the capsules the cost ranges

from Sfr 2.53 – 6.86 (USD 2.71 – 7.35) per 30 mg oxycodon. 30ml oral solution 1mg/ml

costs in Switzerland Sfr 44,30 (USD 47.45), which is Sfr 4.43 (USD 4.74) per 30 mg

oxycodone.6

The cost of the preparations mentioned in this application, as far as available in the

Netherlands, are as follows:

2. Comparative cost-effectiveness presented as range of cost per routine There is no standard dosage for oxycodone for adult patients and therefore it is even more

difficult to define a standard dosage for a child. Foley et al. found that the average terminal

cancer patient needs 75 mg morphine a day during the last three months of his or her life.

[Foley, 2006] This corresponds with a dosage of approximately 30 mg oxycodone per day

orally for the treatment of a ten year old child with comparable pain.

The cost of one day of treatment (30 mg) for this child are presented above for the various

preparations available in Switzerland and the Netherlands. For all dosage forms and strengths,

the price range for 30 mg of oxycodone is Sfr 0.80 – 8.51 (US$ 0.85 – 9.11) for Switzerland.

In the Netherlands, the cost of one day of treatment (30 mg) for this child ranges for all

strengths of immediate release tablets from € 1.77 to € 2.10 (US$ 2.29 - 2.72) per 30 mg, for

all strengths of slow-release tablets from € 1.17 to € 2.34 (US$ 1.51 - 3.03) per 30 mg, for all

strengths of capsules from € 2.04 to € 8.22 (US$ 2.64 - 10.63) per 30 mg and for the oral

liquid it is € 20.40 (US $ 26.39) per 30 mg. The overall range is from € 1.17 to € 20.40

(US$ 1.51 – 26.39).

As the Swiss price level for medicines is known to be high, the Swiss prices should be

regarded as the upper end of the price range. Among European countries, the Netherlands has

relatively low medicines prices.

Summary of regulatory status of the medicine in several countries Oxycodone was introduced as an analgesic in Germany in 1939. Currently, it is on the

market in Germany, the Netherlands, Switzerland, the United States of America and many

other countries.

Oxycodone is subject to international control under the Single Convention on Narcotic

Drugs, 1961. For enabling good access in all countries, the World Health Organization

published the policy guidelines Ensuring Balance in National Policies on Controlled

Substances, guidance for availability and accessibility of controlled medicines in 2011

[Ensuring Balance, p.4].

Availability of pharmacopoeial standards (British Pharmacopoeia,

International Pharmacopoeia, United States Pharmacopoeia) The International Pharmacopoeia, the British Pharmacopoeia and the Unites States

Pharmacopoeia all contain monographs for oxycodone hydrochloride. [The International

Pharmacopoeia, 2011, CD-version; British Pharmacopoeia, 2012, p. 10916; United States

Pharmacopoeia, online version accessed 14 September 2012].

In addition, the United States Pharmacopoeia has monographs on Oxycodone

Hydrochloride oral solution, Oxycodone Hydrochloride Tablets and Oxycodone

Hydrochloride Extended Tablets. [United States Pharmacopoeia, online version accessed 14

September 2012].

Proposed new text for the WHO Model Formulary The publication of the WHO Guidelines on the pharmacological treatment of persisting pain

in children entails also a pharmaceutical profile on oxycodone, following the monograph format of the

WHO Formulary for children. The profile contains updated dosage schedules and instruction for

titrating the patient to adequate pain management and for weaning opioids. A proposed text is

provided below. 7

Oxycodone

ATC Code: N02AA05

Tablet: 5 mg, 10 mg, 15 mg, 20 mg, 30 mg (as hydrochloride).

Skilled tasks: warn the patient or caregiver about the risk of undertaking tasks requiring

attention or coordination, for example, riding a bike.

Dosage:

Starting dose for opioid-naive patients: Oral (immediate-release formulation):

infant 1–12 months – 50–125 mcg/kg every 4 hours;

child 1–12 years – 125–200 mcg/kg every 4 hours, max 5 mg. Oral (slow-release formulation):

7 Proposed monograph identical to the monograph in the WHO Guidelines on the Pharmacological Treatment of Persisting Pain in Children (page 78 - 80), except that the terminology “slow-release” is used here.


19

child over 8 years – 5 mg every 12 hours.

Continuation: after a starting dose according to the dosages above, the dosage should be

adjusted to the level that is effective (with no maximum), but the maximum dosage increase

is 50% per 24 hours in outpatient settings. Experienced prescribers can increase up to 100%

with careful monitoring of the patient.

Dose for breakthrough pain

Oral (using immediate-release preparation):

infant or child: Additional oxycodone may be administered as frequently as

required with a maximum of 5–10% of the regular daily baseline oxycodone dose. If

repeated breakthrough doses are required, adjust the regular baseline oxycodone

dose guided by the amount of oxycodone required for breakthrough pain with a

maximum increase of 50% per 24 hours.

Dosage discontinuation: for short-term therapy (7–14 days), the original dose can be

decreased by 10–20% of the original dose every 8 hours increasing gradually the time

interval. In the case of a long-term therapy protocol, the dose should be reduced not more

than 10–20% per week (79,80).

Renal impairment: mild (GRF 20–50 ml/min or approximate serum creatinine 150–300

micromol/l) to severe (GFR <10ml/min or serum creatinine > 700 micromol/l) – dose

reduction may be required; start with lowest dose and titrate according to response.

Hepatic impairment: moderate and severe; reduce dose by 50% or avoid use.

Adverse effects:

common – nausea, vomiting, constipation, diarrhoea, dry mouth, sedation, biliary

spasm, abdominal pain, anorexia, dyspepsia, pruritus, somnolence, dizziness;

less common – muscle rigidity, hypotension, respiratory depression, bronchospasm,

dyspnoea, impaired cough reflex, asthenia, anxiety, chills, muscle fasciculation,

postural hypotension, hallucinations, vertigo, euphoria, dysphoria, dizziness,

confusion;

uncommon – bradycardia, tachycardia, palpitation, oedema, mood changes,

dependence, drowsiness, sleep disturbances, headache, miosis, visual disturbances,

sweating, flushing, rash, urticaria, restlessness, difficulty with micturition, urinary

retention, ureteric spasm, gastritis, flatulence, dysphagia, taste disturbance, belching,

hiccups, vasodilation, supraventricular tachycardia, syncope, amnesia, hypoasthesia,

pyrexia, amenorrhoea, hypotonia, paraesthesia, disorientation, malaise, agitation,

speech disorder, tremor, dry skin;

rare – raised intracranial pressure, circulatory depression, cardiac arrest, respiratory

arrest, shock, paralytic ileus, seizures.

Interactions with other medicines:

central nervous system depressants – additive or potentiating effects with oxycodone;

monoamine oxidase inhibitors* – severe and unpredictable potentiation of opioids;


20

naloxone* – precipitates opioid withdrawal symptoms;

naltrexone* – precipitates opioid withdrawal symptoms;

opioid antagonists/partial agonists* – may precipitate opioid withdrawal symptoms.

* Indicates severe.

Notes:

Oxycodone is subject to international control under the Single Convention on

Narcotic Drugs, 1961.

Slow-release oxycodone preparations must not be crushed or chewed; the child must

be able to swallow the whole tablet.

Administer with food to reduce gastrointestinal upset.

Oxycodone is partially metabolized to an active metabolite, oxymorphone, via

CYP2D6 pathway; slow or ultra-fast metabolizers may experience reduced or

enhanced analgesia and dose-related side-effects.

High strength slow-release tablets should only be used in patients who are opioid

tolerant. Administration of these strengths to non-opioid tolerant patients may cause

fatal respiratory depression.

Naloxone is used as an antidote in case of opioid overdose.

Equianalgesic doses:

When converting from oral morphine to oral oxycodone, use an initial dose conversion ratio

of 1.5:1 (e.g. replace 15 mg morphine with 10 mg oxycodone). Then titrate to optimize the

analgesia.

A2.2.3 Strong opioids essential in pain treatment

Clinical question

In children with persisting pain due to medical illnesses, what are the benefits as compared to the risks

(hastening death, developing dependence, respiratory depression, influencing the child's development)

of taking regular or intermittent morphine for pain control as compared with a similar group of

patients with persisting pain not taking any opioid analgesics?

Recommendation

4. The use of strong opioid analgesics is recommended for the relief of moderate to severe

persisting pain in children with medical illnesses.

Strong recommendation, low quality of evidence

Domains and considerations

Quality of evidence

Although, no systematic reviews or randomized control trials were retrieved to guide determination of

the balance between the benefits and disadvantages of the use of strong opioids in children, the panel

considered indirect evidence from adult chronic non-cancer pain (71).

The panel noted the following statement, which supported the inclusion of morphine in the 2010

EMLc: “Morphine is the strong opioid of choice in moderate to severe pain in children and this is

confirmed by a number of consensus guidelines. There is extensive clinical experience of its use in

children and its use should be promoted to ensure adequate analgesia as necessary” (72).

Uncertainty: none.

Risks/benefits

Benefits

The efficacy of strong opioids in the relief of pain is well accepted. The panel noted, however, that

studies comparing opioids are possible in this age group provided that acceptable and appropriate trial

methodology is used.

Risks

Risks associated with severe side-effects and mortality arising from medication errors were

considered manageable, although more data on long-term use in children are necessary.

Uncertainty: none


25

Values and acceptability

In favour

The panel valued access to effective treatment of pain in children.

Against

None

Uncertainty: none.

Cost

Although access to strong opioids is variable, price is not generally a significant barrier for a number

of strong opioids.

Uncertainty: none.

Feasibility

Access to strong opioids for medical use remains a challenge worldwide. However, the rational use of

opioid analgesics in countries with limited financial and human resources is feasible and

recommended.

Uncertainty: none.

Policy agenda

Countries should review, and if necessary, revise their policies and regulations to ensure availability

and accessibility of opioid analgesics for the relief of moderate to severe pain in children as provided

for in the preamble of the Single Convention on Narcotic Drugs, 1961.

A2.2.4 Choice of strong opioids

Clinical question

In children with persisting pain due to medical illnesses, what is the evidence to support the use of

morphine as a gold standard for strong opioids as compared to the use of other strong opioids (in

particular fentanyl, hydromorphone, oxycodone and methadone) in order to achieve rapid, effective

and safe pain control?

Recommendations

5. Morphine is recommended as the first-line strong opioid for the treatment of persisting

moderate to severe pain in children with medical illnesses.


26

6. There is insufficient evidence to recommend any alternative opioid in preference to

morphine as the opioid of first choice.

7. Selection of alternative opioid analgesics to morphine should be guided by considerations

of safety, availability, cost and suitability, including patient-related factors.

Strong recommendations, low quality of evidence


Quality of evidence

The panel noted that morphine has been available for a considerable amount of time and that high

quality of evidence is unlikely to be available. The second recommendation was based on

comparisons between different opioids and routes of administration in acute pain and post-operative

pain in children. (Annex 4. Evidence retrieval and appraisal, GRADE tables 2–4, 6, 7). The assessed

level of quality of evidence was downgraded because of the differences in conditions treated and

duration of treatment.

Uncertainty: yes.

Risks/benefits

Benefits

Morphine is well established as first-line strong opioid.

Risks

Risks are well described and considered to be manageable.

Uncertainty: no, for the use of morphine as a first-line opioid analgesic; yes, in relation to the

comparative safety and efficacy of different opioids.


In favour

The panel valued access to effective treatment.

Against

None

Uncertainty: none.

Cost


27

Morphine is relatively inexpensive, although prolonged-release oral solid forms are more costly.

Uncertainty: none.

Feasibility

A wide range of morphine formulations have been already included in the 2010 EMLc:

granules, slow-release (to mix with water) – 20 mg, 30 mg, 60 mg, 100 mg, 200 mg

injection – 10 mg (morphine hydrochloride or morphine sulfate) in 1 ml ampoule

oral liquid – 10 mg (morphine hydrochloride or morphine sulfate)/5 ml

tablet – 10 mg (morphine sulfate)

tablet (prolonged release) – 10 mg, 30 mg, 60 mg, 100 mg, 200 mg (morphine sulfate).

Uncertainty: none.

Research agenda

Comparative trials of strong opioids, including fentanyl, hydromorphone, oxycodone and methadone,

in the treatment of persisting moderate to severe pain in children of all ages with medical illnesses are

needed. They should investigate effectiveness, side-effects and feasibility of use in this population.

Child appropriate oral solid dosage forms are needed.

A2.2.5 Prolonged-release versus immediate-release morphine

Clinical question

In children with persisting pain due to medical illnesses, should prolonged-release morphine be used

in preference to immediate-release morphine to achieve and maintain effective and safe pain control?

Recommendations

8. It is strongly recommended that immediate-release oral morphine formulations be available

for the treatment of persistent pain in children with medical illnesses.

9. It is also recommended that child-appropriate prolonged-release oral dosage forms be

available, if affordable.



28


Quality of evidence

There is insufficient evidence to support the use of prolonged-release over immediate-release

morphine as a sole agent. The only available evidence is in adults (Annex 4. Evidence retrieval and

appraisal, GRADE Table 10). The Cochrane review found that, in spite of the relevance of this

comparison, only 15 studies of 460 participants compared prolonged-release morphine preparations

with immediate-release morphine (115). None of the trials were large, having a median size of 27

participants (age range: 16–73). The results of these trials show that immediate-release and slow-

release morphine formulations are equivalent for pain relief. Approximately 6% of participants

(adults) in the studies who received morphine (any type) experienced intolerable adverse effects.

Uncertainty: yes, in relation to children since no studies are available in this age group.

Risks/benefits

Benefits

Immediate-release oral morphine needs to be administered more frequently, but it is always necessary

in the management of episodic or breakthrough pain.

Risks

Adherence to long-term treatment with immediate-release oral morphine may be problematic.

Uncertainty: none.


In favour

The panel valued access to immediate-release oral morphine and noted that commercially marketed

prolonged-release oral morphine formulations are sometimes the only products available for

procurement.

Against

None

Uncertainty: none.

Cost

Immediate-release oral morphine is relatively inexpensive but may not be commercially available in

all countries. Morphine powder for extemporaneous preparation may be available, but requires access

to pharmacists and suitable diluents, and its compounding may be subject to legal restrictions. The

stability of such preparations needs to be investigated.


29

Uncertainty: none.

Feasibility

No problem of feasibility, rather affordability for prolonged-release morphine formulation.

Uncertainty: none.

Research agenda

Research into appropriate formulations for the extemporaneous preparation of oral liquid morphine is

needed. Dissemination of available evidence on the preparation of stable extemporaneous

formulations is encouraged.

A2.2.6 Opioid rotation and opioid switching

Clinical question

In children with persisting pain due to medical illnesses, what is the evidence to support opioid

rotation policies to prevent dose escalation and side-effects?

Recommendations

10. Switching opioids and/or route of administration in children is strongly recommended in

the presence of inadequate analgesic effect with intolerable side-effects.

11. Alternative opioids and/or dosage forms as an alternative to oral morphine should be

available to practitioners, in addition to morphine, if possible.

12. Routine rotation of opioids is not recommended.



Quality of evidence

No systematic reviews or randomized control trials were found in children. A Cochrane Review

exclusively looked for and found no RCTs on opioid switching or rotation in adults and children.

Identified case reports, uncontrolled and retrospective studies were examined in order to determine

the current level of evidence (116). The review concluded that although for patients suffering chronic

cancer pain opioid switching may be the only option for enhancing pain relief and minimizing opioid

toxicity, there is a current lack of an evidence base for this therapeutic strategy. A systematic review

published in 2006 (117), identified one retrospective study of opioid switching in 22 children with

cancer pain. This review described a positive response to switching in patients intolerant to a

particular opioid, but noted that RCTs are lacking and that the observations were based on

uncontrolled data.

Uncertainty: yes, in relation to the potential utility of rotation policies; no, in relation to switching of

opioid and/or route of administration in the presence of inadequate effect or intolerable side-effects.

Risks/benefits

Benefits

The panel placed a high value on effective use of adequate doses of the chosen opioid.

Risks

Risks are well described and considered to be manageable. Access to age-appropriate dose conversion

table for different opioids is necessary for safe switching.

Uncertainty: none.


In favour

The panel placed high value on treating rather than not treating pain and providing an alternative

when response is inadequate and side-effects are intolerable.

Against

None

Uncertainty: none.

Cost

Alternative opioids to morphine might be more expensive. However, there are regional variations in

costs and some alternatives to morphine may even be cheaper.

Uncertainty: none.

Feasibility

Access to an age-appropriate dose conversion table for different opioids is necessary for safe

switching.

Uncertainty: yes.

Policy and research agenda

The panel requests an update of the 2004 Cochrane review on opioid switching, including data from

children, if available. Opioid rotation policies lend themselves to investigation by prospective trials.

Such research is encouraged. Research on dose conversion in different age groups is necessary.
