VNRS B50A-ADVANCED PHARMACOLOGY PART A
Stephanie Engler, RNMonday 1:15-2:30pmsengler@bakersfieldcollege.edu
WELCOME TO PHARMACOLOGY!
• Syllabus• Content is board approved- some
review, but we will be digging deeper!• Expectations from this class….
• Please do your homework• Be ready to participate in class• Please bring 3 scantrons to class
• How can I help you succeed???
TO BE SUCCESSFUL IN THIS CLASS………
• Come to class with homework prep questions answered- find on website
• Bring lecture notes to class- print from website
• Bring a blank concept map to class for additional note taking
• Study from your lecture notes and additional notes in class- use your text book for clarification of material covered
• Participate in group “round tables” when available- good time to review exams and ask questions
LET’S GET STARTED…………
Unit 1- Introduction•See class handout
Unit 2- Medications Administered for Gastrointestinal Disorders•GI review-http://www.youtube.com/watch?v=Z7xKYNz9AS0&feature=fvsr •Liver disease, Pancreatitis & Insulin notes•Groups- answer discussion ?’s
GI MEDS AND PLAN OF CARE
PLAN FOR THE DAY:
• Quick Notes Review
• Case Study
• NCLEX Questions
GASTRIC ACIDSystem•Esophagus•Stomach•Liver/gallbladder•Pancreas•Small/large intestine
Gastric acid production•Parietal cells- H+ production•Receptors- histamine2
Function•Stomach pH 1-4•Digestion•Defense against infection
WHAT DO WE DO WITH THE OVERPRODUCTION OF THIS ACID????
****Give antacids= to neutralize!•Milk of Magnesia (magnesium hydroxide)•TUMS (calcium carbonate)Heartburn, gastritis, peptic ulcer disease (PUD)
****Suppress gastric acid!H2 receptor blockers- bind to H2 receptor•Pepcid (famotidine)•Decrease HCl acid production•Decrease heartburnGERD, erosive esophagitis, PUD, H. pylori, gastritis, prevent stress ulcers
Gastric barrier- adheres to gastric mucosa/ binds to ulcer•Carafate (sucralfate)Decrease heartburn

WHAT DO WE DO WITH THE OVERPRODUCTION OF THIS ACID????
****Suppress gastric acid!
Proton pump inhibitors (PPI)- blocks proton pump, stops HCl production•Prevacid (lansoprazole)•Prilosec (omeprazole)•Protonix (pantoprazole)Decrease HCl production, decrease heartburn•Caution with hepatic disease!!!!
GASTROINTESTINAL CASE STUDYHistory of present illness (HPI):
Mr. D- 70 year old male- enters your clinic with a complaint of severe upper abdominal pain that occurs mostly in the evening hours. It is relieved by food, although he vomits his meals several times each week. Wife states intermittent confusion in last month.

RESPIRATORY MEDS AND PLAN OF CARE
PLAN FOR THE DAY:
• Respiratory Review (A&P/ Structures)
• Mediators of inflammation
• Respiratory defense mechanisms
• Homework Review
RESPIRATORY MEDS AND PLAN OF CARE
RESPIRATORY MEDS AND PLAN OF CARE
The respiratory system has built-in methods to prevent harmful substances from entering the lungs:
•Your nose moistens and warms the air.•The hair (cilia) in your nose helps filter out large particles.•Mucus produced by cells in the trachea and bronchial tubes keeps air passages moist and aids in trapping dust, bacteria, and other substances.•Cilia in the air passages move in a sweeping motion upwards towards the throat and mouth to get the mucus and bacteria etc out of the lungs.
RESPIRATORY MEDS AND PLAN OF CARE
Mediators of inflammation
1. Bradykinin, complement, prostaglandin.2. Leukotrienes.3. Histamine.4. Mast cells.
Respiratory defense mechanisms
1. Cough. 2. Reflex bronchoconstriction. 3. Filtration, mucociliary response. 4. Alveolar macrophages -Macrophages engulf and digest
foreign materials in a process known as phagocytosis.
RESPIRATORY MEDS AND PLAN OF CARE
Asthma- caused by inflammation in the airways, causes the airways of the lungs to swell and narrow, leading to wheezing, shortness of breath, chest tightness, and coughing.
Chronic obstructive pulmonary disease (COPD)- Chronic obstructive airways disease; Chronic obstructive lung disease; Chronic bronchitis; Emphysema; Bronchitis – chronic•Chronic bronchitis- which involves a long-term cough with mucus•Emphysema- which involves destruction of the lungs over time
Pneumonia- an inflammation of the lungs caused by an infection
RESPIRATORY MEDS AND PLAN OF CARE
• Drugs affecting the respiratory system• Bronchodilators
• Adrenergic agonists- • Proventil (albuterol)- short acting• Xopenex (levalbuterol)- short
acting• Serevent (salmeterol)- long acting
• Leukotriene inhibitors• Anticholinergics
• Decrease Inflammation• Glucocorticoid steroids
• Antihistamines• Decrease secretions
MEDICATIONS FOR THE INTEGUMENTARY SYSTEM
• Burns- see handout
• Eczema- corticoidsteroid creams
• Psoriasis- • corticoidsteroid creams, • topical retinoids (Tazarotene),• Vit D analogues (Dovonex)
PSORIASIS & ECZEMA
BURNS
