Identification
- Summary
Dicyclomine is an antimuscarinic agent used to treat IBS.
- Brand Names
- Bentyl
- Generic Name
- Dicyclomine
- DrugBank Accession Number
- DB00804
- Background
Dicyclomine is a muscarinic M1, M3, and M2 receptor antagonist as well as a non-competitive inhibitor of histamine and bradykinin used to treat spasms of the intestines seen in functional bowel disorder and irritable bowel syndrome.3,4,5,6 Though it is commonly prescribed, its recommendation may have been based on a small amount of evidence and so its prescription is becoming less favourable.7
Dicyclomine was granted FDA approval on 11 May 1950.6

Dicyclomine is an anticholinergic drug used to relax the smooth muscles of the intestines.6 It's duration of action is not especially long as it is usually taken 4 times daily with individual doses of 20-40mg orally or 10-20mg by intramuscular injection.6 Dicyclomine should not be administered intravenously.6
- Mechanism of action
Dicyclomine achieves its action partially through direct antimuscarinic activity of the M1, M3, and M2 receptors; and partially through antagonism of bradykinin and histamine.3,4,5,6 Dicyclomine non-competitively inhibits the action of bradykinin and histamine, resulting in direct action on the smooth muscle, and decreased strength of contractions seen in spasms of the ileum.4

Data regarding plasma protein binding of dicyclomine is not readily available.6
- Metabolism
The metabolism of dicyclomine has not been well researched.1
- Route of elimination
Dicyclomine is 79.5% eliminated in the urine and 8.4% in the feces.1,6
- Half-life
The mean plasma elimination half life is approximately 1.8 hours.1,6
- Clearance
Data regarding the clearance of dicyclomine is not readily available.6

Drug Interaction Integrate drug-drug
interactions in your softwareAbacavir Dicyclomine may decrease the excretion rate of Abacavir which could result in a higher serum level. Aceclofenac Aceclofenac may decrease the excretion rate of Dicyclomine which could result in a higher serum level. Acemetacin Acemetacin may decrease the excretion rate of Dicyclomine which could result in a higher serum level. Acetaminophen Acetaminophen may decrease the excretion rate of Dicyclomine which could result in a higher serum level. Acetazolamide Acetazolamide may increase the excretion rate of Dicyclomine which could result in a lower serum level and potentially a reduction in efficacy. - Food Interactions
- Avoid alcohol. Alcohol may increase drowsiness caused by dicyclomine.
- Drink plenty of fluids. Dicyclomine may reduce sweating, increasing the risk of overheating in warm weather or during exercise.
