Clinical Overview
Cinnarizine is a piperazine-derivative labyrinthine sedative and peripheral vasodilator. It selectively blocks voltage-gated T-type calcium channels, inhibiting trans-membrane calcium influx in vestibular sensory cells and vascular smooth muscle, improving labyrinthine microcirculation and suppressing motion-induced vestibular overstimulation. Indicated for vestibular vertigo, motion sickness prophylaxis, and peripheral vascular disorders.
