Riodipine

All the preparations under study were i.v. administered to pregnant Wistar rats in the doses adequate to therapeutic those on pregnant woman basis. Within 10 minutes, a drop both in the amplitude and in the rate of the myometrium potentials were found.

A comparative study of pharmacodynamics and clinical efficacy of nimodipine, nifedipine and foridon in ischemic stroke (late recovery and residual period) was performed in 97 patients with ischemic stroke. It was found that nimodipine, nifedipine and foridon at late recovery or residual stages significantly improved higher psychic functions, promoted regression of neurologic disorders and optimized social rehabilitation. Nimodipine, primarily, decreased the intensity of neurological disorders, improved higher psychic functions and had a positive impact on cerebral hemodynamics. Nifedipine primarily improved central hemodynamics (increased stroke output and ejection fraction). Foridon is most effective selective pharmacodynamic impact on peripheral hemodynamics (stimulated arteriolar blood flow, diminished venous capacity and spasticity), i.e. normalized peripheral blood flow.
