Question:
Which of the following is not correct for the \( H_1 \) receptor antagonists?
Which of the following is not correct for the \( H_1 \) receptor antagonists?
Show Hint
\( H_1 \) antagonists are involved in allergic symptom relief, not gastric secretion control.
Updated On: Jun 16, 2025
- Strongly block the increased capillary permeability caused by histamine
- Suppress the flare and itching caused by intradermal injection
- Always suppress the gastric secretion
- Relieve the allergic reactions
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
\( H_1 \) receptor antagonists primarily act on allergic responses such as capillary permeability, flare, and itching. Gastric acid secretion is regulated by \( H_2 \) receptors, not \( H_1 \). Thus, they do not suppress gastric acid secretion.
