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.
