Pharmacology – Drug Development 1. Preclinical testing
▪ 3 ½ years▪ Lab & animal research (rats)▪ Drug evaluated for safety
2. Investigational New Drug Application▪ Drug company files IND with FDA▪ Must be approved or disapproved by FDA within 30
days 3. Clinical Trials
▪ Phase I▪ 1 year, 20-80 healthy volunteers (no disease)▪ Study of a drug’s safety profile & safe dosage▪ Studies Pharmacokinetics (absorption, distrib, metab,
excretion)

Pharmacology – Drug Development
Phase II▪ Controlled studies of 100-300 volunteers (people
with disease)▪ To assess drug effectiveness and safe dosage, 2
years Phase III▪ 3 years▪ Involves 1000-3000 patients in clinics & hospitals▪ Use of placebo▪ Physicians closely monitor all patients to
determine safety, efficacy, and adverse reactions

Pharmacology – Drug Development
Phase IV 2 years, post-release of drug To further assess therapeutic & adverse
effects Black Box Warning: placed on drug by
FDA if severe reactions are occurring▪ ie: Advair, Accutane

Pharmacology –Drug Development
4. New drug application Follows completions of all 3 clinical trials Report of all scientific data (100 pages) FDA has 6 months to review and approve
Final approval: New drug available to physicians to prescribe
Drug company must submit periodic reports to FDA
$12 billion in drug research and development per year, rising

Cultural Practices
Native American▪ Harmony w/ nature, evil spirits cause disease
Asian▪ Traditional medicine, herbal remedies
African▪ Folk medicine, “healers”
Western▪ Prevention of disease, education, medications
Hispanic▪ Health = good luck, Illness = bad luck, bad deed▪ Heat and cold remedies instead of medicines

Medication Preparation for Clinical
HEPARIN Classification: Anticoagulant,
Antithrombotic Action: Prevents conversion of
prothrombin to thrombin, prevents thrombus formation
Indications: To prevent & treat thromboembolism and PE; also used to maintain IV catheter patency (in low doses)
Contraindications: bleeding, thrombocytopenia, severe liver disease
![Page 9: Schedule I – Only w/ approved protocol ▪ Heroin, marijuana Schedule II – Written rx only, no refills ▪ Codeine, morphine, methadone, oxycontin, ritalin,](https://reader036.vdocuments.mx/reader036/viewer/2022062717/56649e235503460f94b10c1e/html5/thumbnails/9.jpg)
HEPARIN (continued) Adverse Effects: bleeding, anemia,
pain at injection site Route: IV or subcutaneous;
administer in abdominal tissue Dosage: 5,000 units q 8-12 hr.
(subcut) Nursing Implications:
Assess for S/S bleeding (gums, nose, bruising, black stools, hematuria)
![Page 10: Schedule I – Only w/ approved protocol ▪ Heroin, marijuana Schedule II – Written rx only, no refills ▪ Codeine, morphine, methadone, oxycontin, ritalin,](https://reader036.vdocuments.mx/reader036/viewer/2022062717/56649e235503460f94b10c1e/html5/thumbnails/10.jpg)
HEPARIN (continued) Assess injection site for hematoma,
ecchymosis Monitor PTT, Hg, Hct, Platelets
**Antidote = Protamine Sulfate
Refer to Davis Drug Guide for Nurses

Heparin Absorption: Quickly absorbed after injection Distribution: Does not cross placenta or enter
breast milk, Highly bound to proteins Metabolism: probably metabolized by lymph
system and spleen, unknown Excretion: removed by lymph system and spleen ½ life: 1-2 hour, dependent upon dosage Onset: 20-60 min. Peak: 2 hrs Duration: 8-12 hrs.
