Drotaverine HCl is a smooth muscle relaxant belonging to the isoquinoline chemical class. It works by inhibiting phosphodiesterase-IV (PDE4), leading to increased levels of cyclic AMP (cAMP) in smooth muscle cells, which results in muscle relaxation. Unlike anticholinergic agents, drotaverine does not cause dry mouth or blurred vision, making it a safer option for relieving spasms.
Drotaverine HCl works by selectively inhibiting the enzyme phosphodiesterase-IV (PDE4) in smooth muscle cells, which leads to an increase in cyclic AMP (cAMP) levels. Elevated cAMP causes relaxation of smooth muscles by reducing calcium ion concentration inside the cells, thereby relieving spasms and cramps without affecting normal muscle tone. Unlike anticholinergic agents, drotaverine does not block acetylcholine receptors, so it avoids common side effects like dry mouth and blurred vision. This mechanism makes it effective for treating smooth muscle spasms in conditions such as abdominal pain, renal colic, and menstrual cramps.
