Biochem/physiol Actions

Drotaverine (Drotaverin) is an isoquinoline-based PDE4-selective phosphodiesterase (PDE) inhibitor and an L-type voltage-dependent (voltage-operated) calcium channel (L-VDCC or L-VOCC) blocker that exhibits in vivo antispasmodic efficacy without anticholinergic effects.
It is a benzylisoquinoline derivative. Drotaverine acts as a smooth muscle relaxant.

The effect of the isoquinoline derivative, drotaverine on the specific binding of [(3)H]nitrendipine and [(3)H]diltiazem to pregnant rat uterine membranes was examined. Drotaverine inhibited the specific [(3)H]nitrendipine and [(3)H]diltiazem bindings with IC(50) values of 5.6 and 2.6 microM, respectively. Saturation

Drotaverine is considered an inhibitor of cyclic-3',5'-nucleotide-phophodiesterase (PDE) enzymes; however, published receptor binding data also support the potential L-type voltage- operated calcium channel (L-VOCC) blocking effect of drotaverine. Hence, in this work, we focus on the potential L-VOCC blocking effect
