Duspatalin Hydrochloride (Mebeverine Hydrochloride) is a specialty chemical and selective antispasmodic agent primarily used in pharmaceutical research, as a reference standard, and in the treatment of irritable bowel syndrome (IBS) and other functional gastrointestinal disorders.

It works by relaxing the smooth muscles in the gastrointestinal tract, which helps to reduce spasms and associated pain. This makes it effective in alleviating symptoms such as abdominal cramps, bloating, and discomfort. It is often prescribed for patients who experience these symptoms frequently, providing relief without significantly affecting normal gut motility.

The medication is typically taken orally and is available in extended-release formulations to ensure prolonged action, making it a convenient option for managing chronic conditions. It is generally well-tolerated, with minimal side effects, making it a preferred choice for long-term management of IBS-related symptoms.
