What is Drotaverine Hydrochloride used for?
Drotaverine Hydrochloride acts as a smooth‑muscle relaxant and is indicated for several spasm‑related conditions: - Abdominal cramping: relieves painful intestinal spasms. - Menstrual pain (dysmenorrhea): reduces uterine muscle contractions. - Biliary colic: eases spasms of the biliary tract. - Renal colic: diminishes ureteral smooth‑muscle spasm. - Other smooth‑muscle spasm conditions: provides symptomatic relief in various visceral spasm disorders.
