Dicyclomine, also known by its brand name Bentyl, is a medication primarily used to treat gastrointestinal (GI) disorders. It belongs to a class of drugs called antispasmodics, which help relieve muscle spasms in the GI tract. Dicyclomine can be found in various forms, including tablets, capsules, and syrups, and is available only with a prescription.

Historical Background

Dicyclomine was first introduced in the 1950s and has since become a commonly prescribed medication for conditions such as irritable bowel syndrome (IBS) and other GI disorders. Over the years, it has undergone refinements and remains a valuable tool in the management of abdominal discomfort and spasms.

Mechanism of Action

Dicyclomine works by inhibiting the action of acetylcholine, a neurotransmitter that plays a role in muscle contractions. By blocking acetylcholine’s effects on the smooth muscles of the GI tract, dicyclomine helps reduce muscle spasms and alleviate associated pain and discomfort.

Availability and Forms

Dicyclomine is available in various formulations, including oral tablets, capsules, and oral suspensions. The choice of form depends on the patient’s age, condition, and physician’s recommendation.
