Pinaverium is a spasmolytic agent used for the symptomatic treatment of irritable bowel syndrome (IBS) and functional disorders of the biliary tract.
Pinaverium interacts with the 1,4-dihydropyridine binding sites on voltage dependent L-type calcium channels located on GI smooth muscle cells in a competitve manner . The binding site is located in the alpha 1S subunit and pinaverium most likely antagonizes the action of calcium ions by stabilizing a non-conducting channel state . Pinaverium inhibits smooth muscle contractions of the GI tract by inhibiting inward calcium current and calcium influx. It is suggested that pinaverium may be able to bind to both closed or inactivates states of the calcium channel with similar affinity .
Pinaverium is indicated for the symptomatic treatment of irritable bowel syndrome (IBS) and functional disorders of the biliary tract.
