Definition

An orally available bromide salt form of pinaverium, a calcium channel blocker (CCB) with antispasmodic activity. Upon oral administration, pinaverium blocks the voltage-dependent calcium channels and inhibits calcium ion influx into the smooth muscle cells located in the gastrointestinal (GI) tract. This prevents smooth muscle contraction and relaxes the GI tract. In addition, pinaverium may both reduce bowel uptake of and facilitate the function of locally active, co-administered drugs.
