Drugs Used For gastric Acid Secretion

Question 1

Proton Pump Inhibitors (PPIs)

Answer 1

Omeprazole, Pantoprazole

Mechanism: Yeh H+/K+ ATPase (proton pump) ko parietal cells mein inhibit karte hain, jo acid production ka final step rok dete hain.

Question 2

H2-Receptor Antagonists

Answer 2

Ranitidine, Famotidine

Mechanism: Yeh parietal cells par H2 receptors ko block karte hain, jo histamine ko acid secretion ko stimulate karne se rok dete hain.

Question 3

Antacids

Answer 3

Aluminum hydroxide, Magnesium hydroxide

Mechanism: Yeh maujooda stomach acid ko neutralize karte hain, symptomatic relief dete hain lekin acid production par koi asar nahi dalte.

Question 4

Anticholinergics

Answer 4

Atropine

Mechanism: Yeh muscarinic receptors ko block karte hain, isse parietal cells ko acetylcholine se stimulate hone se rok dete hain.

Question 5

Prostaglandin Analogues

Answer 5

Misoprostol

Mechanism: Yeh prostaglandins ki action ko mimic karte hain, acid secretion ko inhibit karte hain aur protective mucus production ko stimulate karte hain.
