Drotaverine
AntispasmodicUses of Drotaverine
Drotaverine is an antispasmodic medicine used to relieve smooth muscle spasms and the pain associated with them.
Drotaverine is commonly used for:
• Menstrual pain (dysmenorrhoea): Relieves cramping and lower abdominal pain caused by uterine muscle spasms during menstruation.
• Abdominal pain due to gastrointestinal spasm: Eases cramping pain in the stomach and intestines caused by smooth muscle spasm.
• Renal colic (kidney stone pain): Helps relieve severe, spasm-related pain caused by kidney stones moving through the urinary tract.
• Biliary colic (gallstone pain): Relieves spasm and pain in the bile ducts caused by gallstones.
• Gastrointestinal colicky pain: Manages cramping, wave-like abdominal pain associated with digestive disturbances.

How Drotaverine works
- Drotaverine works by relaxing smooth muscle in the walls of internal organs, which relieves spasm-related pain.
- It is classified as an antispasmodic agent. Drotaverine works by inhibiting an enzyme called phosphodiesterase (primarily PDE4), which is found in smooth muscle cells.
- Phosphodiesterase normally breaks down a signalling molecule called cyclic adenosine monophosphate (cAMP) inside smooth muscle cells. By blocking phosphodiesterase, Drotaverine allows cAMP levels to rise within these cells.
- Higher cAMP levels lead to relaxation of the smooth muscle, particularly in the walls of the gastrointestinal tract, urinary tract, bile ducts, and blood vessels. This relaxation reduces or stops the involuntary muscle spasms that cause pain in conditions such as menstrual cramps, kidney stone-related pain, and gastrointestinal colic.
- Because Drotaverine acts directly and selectively on smooth muscle, it provides effective spasm relief without significantly affecting the nervous system, distinguishing it from some other classes of antispasmodic medicines.
