What is Drotaverine Hydrochloride?
Drotaverine Hydrochloride, the active ingredient in No-Spa Comfort, is an antispasmodic (smooth muscle relaxant) presented as an oral tablet for systemic use. It relieves spasms of the gastrointestinal tract, biliary system, urinary tract and uterine muscle, helping to reduce pain associated with these conditions.
