What is Donnatal Extentabs (belladonna alkaloids and phenobarbital)?

Phenobarbital is in a class of drugs called barbiturates. Phenobarbital depresses the activity of your brain and nervous system, causing relaxation.

Belladonna alkaloids produce many effects in the body, including relief from spasms of the gastrointestinal tract (stomach and intestines), the bladder, and the biliary tract. This is helpful in controlling conditions such as colitis, spastic bladder, diverticulitis, infant colic, renal and biliary colic, peptic ulcer, irritable bowel syndrome, splenic flexure syndrome, and pancreatitis.

Belladonna alkaloids also reduce the secretions of many organs, thereby helping to control conditions such as excessive stomach acid production, excessive secretion from the pancreas, and the excessive sweating and drooling associated with diseases like Parkinson's disease.

The combination, belladonna alkaloids and phenobarbital, is used to treat irritable bowel syndrome, inflammation of the intestine, and ulcers in the intestine.
