Dicycloverine, also known as dicyclomine, is an anticholinergic that blocks muscarinic receptors. Dicycloverine was first synthesized in the United States circa 1947.[1]

Medical uses[edit]

A 10-mg oral capsule of dicyclomine hydrochloride, manufactured by Mylan

Dicyclomine is used to treat intestinal hypermotility and the symptoms of irritable bowel syndrome (also known as spastic colon). It relieves muscle spasms and cramping in the gastrointestinal tract by blocking the activity of acetylcholine on cholinergic (or muscarinic) receptors on the surface of muscle cells. It is a smooth muscle relaxant.[2]

In the UK, it is an ingredient of a multiple-ingredient preparation, with an antiflatulent (simethicone) and two antacids, under the trade name Kolanticon. In France, it is an ingredient of a multiple-ingredient preparation, with colchicine, under the brand Colchimax. In India, it is of a compound with paracetamol under the trade name Cyclopam. It is also marketed as Meftal-SPAS containing mefenamic acid along with dicyclomine hydrochloride as an analgesic and antispasmodic.

Side effects[edit]

Dicyclomine can cause a range of anticholinergic side effects such as dry mouth, nausea, and, at higher doses, deliriant effects.[2] Recreational use of this drug for its anticholinergic effects (both low dose for euphoria and high dose for delirium) has been rarely reported; it is also reputed to cause a rapid increase in libido in the first 10-135 minutes after dosing.

Caution[edit]

Breastfeeding is not recommended while using this drug. Users should use care when operating vehicles and/or dangerous machines.[2]

Synthesis[edit]

Dicycloverine synthesis[1]
  1. Double alkylation of phenylacetonitrile with 1,5-dibromopentane leads to the corresponding cyclohexane.
  2. This intermediate is then saponified and the resulting acid esterified with 2-(diethylamino)ethanol.
  3. Catalytic reduction of the aromatic ring yields dicyclomine.
