PUD/GERD meds Flashcards
Proton Pump inhibitor drugs
“Zoles’s”
Esomeprazole (Nexium)
Lansoprazole (Prevacid)
Pantoprazole (Protonix)
Esomeprazole (Nexium)
Lansoprazole (Prevacid)
Pantoprazole (Protonix)
Indiction:
PUD and GERD
-Working with 2 antibiotics to treat H. Pylori
MOA of Zoles
Reduces acid secretion in stomach by binding irreversibly to the enzyme of Na+K+ ATPase Pump
Pump secretes acid, and PPIs inhibit the final pathway of acid secretion by blocking it
Adverse effects of Zoles
Esomeprazole (Nexium)
Lansoprazole (Prevacid)
Pantoprazole (Protonix)
CNS
- headache
- dizziness
GI
- flatulence
- N/V/D
Nursing Concerns for Zoles
Esomeprazole (Nexium)
Lansoprazole (Prevacid)
Pantoprazole (Protonix)
- Take 20-30 min before first meal (proton pump activated by food)
- Short half life (about 1.5 hr) but suppress acid for 24 hrs (irreversible)
- 4 days to achieve maximal effects (not all pump inactivated by first dose)
- Food intake with beneficial bacteria/normal flora like yogurt
- Keep head of bed elevated 30 degrees if you experience heartburn
- DO NOT crush, break or chew tablets/capsule
Assessment for Patients taking Zoles
- Complete medical history, allergies and drug interactions
- Routine liver function tests for prolong use. Interactions
- Vit B12 & Folic Acid can cause malabsorption, Avoid smoking, EtOH, and breastfeeding
Histamine 2 Antagonist

PUD and GERD
MOA for “Dines”
Ranitidine (Zantac)
Cimetidine (Tagamet)
Famotidine (Pepcid)
- Block H2 Receptors on parietal cells in stomach to decrease acid production
- Suppress day time/nocturnal basal gastric acids
Adverse effects for "Dines" Ranitidine (Zantac) Cimetidine (Tagamet) Famotidine (Pepcid)
*Strong Effects on elderly and those with Renal Disease CNS: Confusion Restlessness Hallucinations Depression GI: Elevated Liver Enzymes N/V/D CV: Arrhythmias
Nursing Concerns for "Dines" Ranitidine (Zantac) Cimetidine (Tagamet) Famotidine (Pepcid)
- Rapid absorption from small intestine (30 min onset of action)

- No known effects on the fetus
Interactions with "Dines" Ranitidine (Zantac) Cimetidine (Tagamet) Famotidine (Pepcid)
- DO NOT take with Antacids→ diminished absorption
- DO NOT confuse with H2 Antagonists (Benadryl against allergic rhinitis)
Antacids
Aluminum Hydroxide (AlternaGel)
Aluminum Hydroxide (AlternaGel) is used for?
PUD and GERD
also treats symptoms of heartburn
MOA for Aluminum Hydroxide (AlternaGel)
- Alkaline Substance that neutralizes stomach acid to bring the pH above 3 and inactivates pepsin
- Most isn’t absorbed; Works directly on stomach acid and is secreted in the feces
Adverse affects for Aluminum Hydroxide (AlternaGel) with Sodium bicarbonate (Alka-Seltzer, baking soda)
fluid retention and contraindicated with congestive heart failure
Adverse affects for Aluminum Hydroxide (AlternaGel) with Magnesium hydroxide (Milk of Magnesia)
Fatigue, diarrhea, hypotension, dysrhythmias, hypermagnesemia in renal disease
Adverse affects for Aluminum Hydroxide (AlternaGel) with Calcium carbonate (Titralac, Tums)
Constipation, aggravated kidney stones, milk-alkali syndrome, rebound hyperacidity and metabolic alkalosis
Adverse affects for Aluminum Hydroxide (AlternaGel)
Constipation and Hypophosphatemia (Phosphate depletion)
Some Combinations of 2 Antacids can lead to __________ ?
Metabolic Alkalosis
Nursing Concerns for Aluminum Hydroxide (AlternaGel)
- Complete Medical History
- Stomach pain assessed and evaluated
- Lab values including Electrolyte and Renal Function
- Symptoms of gastric bleed
Interactions for Antacids (Aluminum Hydroxide (AlternaGel))
- Take antacids at least 2 hours before other PO medications
- Adequate Nutrition while taking
Initital Regimen for Helicobacter Pylori
1 PPI and 2 antibiotics
Omeprazole (PPI), Clarithromycin (Biaxin), and Amoxicillin (Amoxil)
for PUD & GERD: Sucralfate (Carafate) MOA
enhancing mucosal defense and promoting healing

PUD, GERD, H, Pylori, Diarrhea
Metoclopramide (Reglan) is for
GERD & N/V
MOA for Metoclopramide (Reglan)
*Antidopaminergic
- blocking dopamine 2 receptors on chemoreceptor trigger zone to inhibit vomiting reflex
- faster emptying of stomach and decreasing esophagus relaxation on GI tract
