About
Cinnarizine is an antihistamine with additional calcium channel blocking properties, primarily utilized for the management of symptoms associated with vestibular disorders and motion sickness. Its therapeutic effects stem from its ability to inhibit the contraction of vascular smooth muscle cells, which helps to improve microcirculation, particularly in the inner ear and cerebral regions. This enhanced blood flow is crucial for stabilizing the vestibular system, which is responsible for balance and spatial orientation. Furthermore, cinnarizine's antihistaminic action helps to reduce the sensation of nausea and vomiting commonly experienced with vertigo and motion sickness. It acts by blocking H1-receptors and also by interfering with calcium influx into vestibular sensory cells, thereby reducing their excitability. The drug also possesses a mild sedative effect, which can be beneficial in alleviating the distress associated with severe dizziness and nausea. It is effective in preventing and treating symptoms such as vertigo, tinnitus, nausea, and vomiting, making it a valuable option for conditions like Meniere's disease and travel sickness.
