Question

which of the following drugs are h₂-blockers for the treatment of gerd?
cytotec
tagamet
amoxicillin
salmeterol

Explanation:

To determine which drug is an \( \text{H}_2 \)-blocker for GERD treatment:

• Cytotec (misoprostol) is a prostaglandin analog, not an \( \text{H}_2 \)-blocker.
• Tagamet (cimetidine) is a well - known \( \text{H}_2 \)-receptor antagonist used to reduce stomach acid, suitable for GERD.
• Amoxicillin is an antibiotic, not an \( \text{H}_2 \)-blocker.
• Salmeterol is a long - acting beta - agonist for respiratory conditions, not an \( \text{H}_2 \)-blocker.

Answer:

Tagamet
