Question

While antacids and antiallergic drugs interfere with the function ofhistamines, why do these not interfere with the function of each other?

Answer 1

Specific drugs affect particular receptors. Antacids and anti-allergic drugs work on different receptors. This is the reason why antacids and anti-allergic drugs do not interfere with each other's functions, but interfere with the functions of histamines.
