Calcium channel blockers cause increase saliva secretion

Calcium channel blockers cause increase saliva secretion:

• a. True.
• b. False.***

The answer is False.

Calcium channel blockers actually decrease saliva secretion, leading to a common side effect of dry mouth (xerostomia). This is because calcium plays a crucial role in the signal transduction pathway for saliva production in salivary gland cells. Blocking calcium channels disrupts this pathway, consequently hindering the flow of saliva.

Therefore, option b. False is the correct answer.
