What is Antispasmodic

Antispasmodic is a combination of phenobarbital and belladonna alkaloids. Phenobarbital belongs to a group of drugs called barbiturates. It slows the activity of your brain and nervous system.

The belladonna alkaloids included in this medication include atropine, hyoscyamine, and scopolamine. Antispasmodic is intended to treat irritable bowel syndrome and ulcers in the intestine.
