Study Notes

Proton Pump Inhibitors (PPI)

Most PPIs are 24-hour delayed-release gel capsules; do not crush or split.
Long-term use can lead to side effects due to reduced stomach HCl acid.
Decreased calcium absorption increases the risk of osteoporosis.
Reduced absorption of magnesium, vitamin B12, and iron necessitates checking levels every couple of years for lifelong users.
Increased risk of renal failure prompts yearly creatinine monitoring and hepatic lab checks.
Lack of acidic barrier elevates infection risks, particularly for C. difficile and pneumonia; caution with initiating PPIs in hospitalized patients unless critical.
Debates exist regarding potential links to dementia, cardiac issues, and reduced efficacy of antiplatelet meds.

PPI Teaching

Do not crush any PPI pills; most are extended-release.
Capsules may be opened and sprinkled on soft food if swallowing is difficult—must swallow whole.
New medication Talicia combines two antibiotics and omeprazole for 14 days in PUD treatment.
Traditional PUD treatment often entails an 8-week PPI trial.
PPI dosage should be taken 30-60 minutes before meals; lowest effective dose is preferred.

H2 Receptor Antagonists (H2RA)

Famotidine, ranitidine (Zantac, now with alternative formulations), and cimetidine are key H2RAs.
Effective in treating heartburn, sour stomach, ulcers, and GERD.
H2RAs can cross the blood-brain barrier, potentially causing confusion in elderly patients.
Advise taking H2RAs 30-60 minutes before meals for optimal effects, especially at night.
Avoid antacids within 30-60 minutes post-H2RA administration to prevent absorption interference.

Antacids

Milk of Magnesia: Effective antacid; may cause diarrhea, use with aluminum hydroxide to balance effects.
Mylanta: A combination antacid; monitor sodium levels in patients with heart conditions.
Pepto-Bismol: Coats the stomach; take on an empty stomach for PUD treatment to ensure efficacy.

Laxatives

Begin with low-dose, bulk-forming laxatives to prevent constipation.
Aim for daily use in hospitalized patients to prevent medication-induced constipation.
Osmotic laxatives (e.g., Miralax) are potent evacuators often used for bowel prep, with a risk of dehydration.
Caution when administering to heart failure patients due to possible sodium increase.

Anti-diarrheal and Antiemetic Medications

Loperamide: Used to manage diarrhea; can cause dizziness and dry mouth, and potential for dehydation.
Dangerous interactions can occur when combined with other medications that induce drowsiness; exercise caution.
Antiemetics: Medications such as ondansetron, metoclopramide, and promethazine block receptors in the CTZ to prevent nausea and vomiting.

Additional Notes on Peptic Ulcer Disease (PUD) and GERD

PUD is characterized by excessive stomach acid leading to discomfort; can overlap with GERD.
20% of the U.S. population has GERD; an increase of 6% also exhibits PUD symptoms.
Treatments include antibiotics for H. pylori, antisecretory agents (H2RAs and PPIs), mucosal protectants, and antacids.

Description

This quiz covers the side effects and risks associated with long-term use of Proton Pump Inhibitors (PPIs). It highlights important considerations such as the impact on calcium, magnesium, B12, and iron absorption, as well as the increased risks of osteoporosis and renal failure. Regular monitoring of health parameters is emphasized for lifelong PPI users.
