Cinnarizine is used to treat and prevent motion sickness, vertigo (including Meniere's disease), symptoms of vestibular disorders such as nausea, vomiting, and dizziness, as well as peripheral vascular conditions like Raynaud's phenomenon and cerebral circulatory disorders.
Cinnarizine works by blocking calcium channels in vascular smooth muscle and the vestibular system, reducing the constriction of blood vessels and suppressing activity in the inner ear's balance center. Its antihistamine properties also help reduce nausea and vomiting signals sent to the brain.
Common side effects include drowsiness, dry mouth, and weight gain. Patients with Parkinson's disease should use caution as it may worsen symptoms. It may enhance the effects of alcohol and sedatives. Pregnant women and those breastfeeding should consult their healthcare provider before use. Do not discontinue abruptly without medical advice.
