Question

An antisecretory drug differs from an antacid by _______.

		destroying proteins
		neutralizing the hydrochloric acid in the stomach
		blocking histamine release from cholinergic and H2 receptors
		coating the lining of the stomach with a protective layer

Answer 1

Option ( C ) is correct. ( Blocking histamine release from cholinergic and H2 receptors)

Explaination :-

Anti- secretory drug is a substance that inhibits secrection of digestive enzymes, hormones or acid. Antacid is a drug that neutralizes gastric acid.

Antisecretory drug works by blocking certain histamine receptor ( H2 receptors ) that are located in the gastric mucosa and protein pump inhibitors that decreases the formation of hydrochloric acid in the stomach by inhibiting transport of H+ ions across the gastric lining.
