Drotaverine, also known by the trade name No-Spa, is an antispasmodic medication used to relieve smooth muscle spasms in the gastrointestinal tract, urinary system, and gallbladder. It is also utilized to enhance cervical dilation during childbirth. Drotaverine works by inhibiting phosphodiesterase IV (PDE4), which relaxes smooth muscles and alleviates spasms.
