What are antagonistic drugs ?

Text Solution

Verified by Experts

Drugs that bind to the receptor site and inhibit its natural function are called antagonistic drugs. For example, the antacid drug cimetidine is called the antagonistic drug since it binds to the receptor site in stomach where otherwise histamine will bind and hence the secretion of HCl is reduced thereby reducing/removing hyperacidity.
