Absorption, Distribution and Excretion
The bioavailability of dicyclomine has not been determined, though it is likely well absorbed as the primary route of elimination is in the urine. Dicyclomine has a Tmax of 1-1.5h.
Dicyclomine is 79.5% eliminated in the urine and 8.4% in the feces.
The volume of distribution for a 20mg oral dose is 3.65L/kg.
Data regarding the clearance of dicyclomine is not readily available.

Metabolism / Metabolites
The metabolism of dicyclomine has not been well researched.

---

Biological Half-Life
The mean plasma elimination half life is approximately 1.8 hours.

Hepatotoxicity
Like other anticholinergic agents, dicyclomine has not been linked to episodes of liver enzyme elevations or clinically apparent liver injury. The metabolism of dicyclomine is not well defined but it is likely metabolized by the liver.
References on the safety and potential hepatotoxicity of anticholinergics are given together in the Overview section on Anticholinergic Agents.

Effects During Pregnancy and Lactation
◉ Summary of Use during Lactation
Dicyclomine has not been well studied during breastfeeding. However, one possible case of apnea has been reported in a breastfed infant that is similar to reactions that have occurred in infants given the drug directly. Dicyclomine should not be used during lactation.
◉ Effects in Breastfed Infants
Relevant published information was not found as of the revision date. The manufacturer reported a breastfed infant who developed apnea during maternal therapy with dicyclomine. Dicyclomine is a possible cause of the reaction.
◉ Effects on Lactation and Breastmilk
Relevant published information in nursing mothers was not found as of the revision date. Anticholinergics can inhibit lactation in animals, apparently by inhibiting growth hormone and oxytocin secretion. Anticholinergic drugs can also reduce serum prolactin in nonnursing women. The prolactin level in a mother with established lactation may not affect her ability to breastfeed.

Dicyclomine is the ester resulting from the formal condensation of 1-cyclohexylcyclohexanecarboxylic acid with 2-(diethylamino)ethanol. An anticholinergic, it is used as the hydrochloride to treat or prevent spasm in the muscles of the gastrointestinal tract, particularly that associated with irritable bowel syndrome. It has a role as a muscarinic antagonist, an antispasmodic drug and a parasympatholytic. It is a tertiary amine and a carboxylic ester. It is functionally related to a 2-diethylaminoethanol and a 1,1'-bi(cyclohexyl)-1-carboxylic acid.
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. 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. Dicyclomine was granted FDA approval on 11 May 1950.
Dicyclomine is an Anticholinergic. The mechanism of action of dicyclomine is as a Cholinergic Antagonist.
Dicyclomine is an anticholinergic agent used to treat gastrointestinal conditions such as acid peptic disease and irritable bowel syndrome. Dicyclomine has not been implicated in causing liver enzyme elevations or clinically apparent acute liver injury.
Dicyclomine is a carboxylic acid derivative and a selective anticholinergic with antispasmodic activity. Dicyclomine blocks acetylcholine from binding to muscarinic receptors on smooth muscle. This agent has a direct relaxing effect on smooth muscle and therefore prevents spasms in the muscles of the gastrointestinal tract, inhibits gastrointestinal propulsive motility, decreases gastric acid secretion and controls excessive pharyngeal, tracheal and bronchial secretion.
A muscarinic antagonist used as an antispasmodic and in urinary incontinence. It has little effect on glandular secretion or the cardiovascular system. It does have some local anesthetic properties and is used in gastrointestinal, biliary, and urinary tract spasms.

Drug Indication
Dicyclomine is indicated for the treatment of functional bowel disorder and irritable bowel syndrome.
FDA Label

---

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. 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.
...MAJOR ACTION APPEARS TO BE NONSPECIFIC DIRECT RELAXANT ACTION ON SMOOTH MUSLCE RATHER THAN COMPETITIVE ANTAGONISM OF ACH.

Pharmacodynamics
Dicyclomine is an anticholinergic drug used to relax the smooth muscles of the intestines. 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. Dicyclomine should not be administered intravenously.
