Spasrex Introduction

Spasrex is an antispasmodic drug which is used to relax the muscles in the digestive system. Spasrex hydrochloride is the hydrochloride salt of an ethylenediamine derivative, mebeverine. It is used in the symptomatic treatment of gastrointestinal spasm associated with irritable bowel syndrome. It helps to reduce symptoms such as stomach cramps, abdominal pain, and irregular and painful bowel movements.

Uses For

Spasrex is used to treat cramps or spasms of the stomach and intestines. It is also used to treat irritable bowel syndrome.

Mechanism of Action

Spasrex works to relax the muscles at the level of the stomach and intestine walls to help reduce abdominal pain, cramps, and irritable bowel syndrome (IBS). It acts on muscarinic receptors (cholinergic receptors) within the intestines, slowing the rate of muscle contraction. This slows the passage of food through the digestive system, increasing the absorption of water through the bowels and ultimately alleviating cramps, pain, and other IBS symptoms.
