Dicyclomine Brand Name– Bentyl
What is Dicyclomine
Dicyclomine is an antimuscarinic, anticholinergic drug. It is used as an antispasmodic agent in the treatment of diarrhea-predominant irritable bowel syndrome.
Although dicyclomine is a tertiary amine, it does not produce characteristic atropine-like effects on the salivary or sweat glands, or on the cardiovascular system.
Dicyclomine is an old drug, but it remains one of the more frequently prescribed agents among the many antimuscarinics currently marketed.
There is a black box warning against the use of this drug in infants < 6 months of age, due to reports of severe adverse effects of dicyclomine in very young infants when the drug was used to treat symptoms of colic.
Dicyclomine was approved by the FDA in 1950.
