Drotaverine: Antispasmodic agents
Drotaverine works by blocking certain enzymes, which results in increased release of chemical substance that causes relaxation of smooth muscles. This kind of action provides relief from stomach pain due to muscle spasms in gastrointestinal tract, urinary system and gall bladder.
