Answer

a) Drug groups for peptic ulcer

GroupExamples
Proton pump inhibitorsOmeprazole, Pantoprazole
H2 receptor antagonistsRanitidine, Famotidine
AntacidsAluminium hydroxide, Magnesium trisilicate
Mucosal protective agentsSucralfate, Misoprostol

b) One group — Proton pump inhibitors MOA: a prodrug that accumulates in the acidic parietal cell canaliculus, converts to its active sulfenamide form, and irreversibly binds H⁺/K⁺-ATPase, blocking the final common step of gastric acid secretion. Uses: peptic ulcer disease, GERD, H. pylori eradication. Adverse effects: hypomagnesemia, fracture risk, B12 deficiency with long-term use.

c) Ondansetron A 5-HT3 receptor antagonist. MOA: blocks serotonin receptors peripherally (vagal afferents) and centrally at the chemoreceptor trigger zone. Uses: chemotherapy/radiotherapy-induced and post-operative nausea/vomiting. Adverse effects: headache, constipation, QT prolongation.
