How Cinaryl Plus works
Cinaryl Plus is a combination of two medicines: Cinnarizine and Dimenhydrinate. Cinnarizine is a calcium channel antagonist which works by preventing constriction of the blood vessels of the inner ear. This improves the microcirculation of the ear. Dimenhydrinate is an antiallergic. It blocks the action of a chemical messenger (histamine) that is responsible for light-headedness in vertigo.

Mode of Action
Cinnarizine has calcium-channel blocking activity selective for arterial smooth muscle. It also has some antihistamine activity. Cinnarizine acts as a labyrinthine sedative. It also improves microcirculation by reducing ischaemia-induced blood viscosity.
Dimenhydrinate is an antihistamine which also has antimuscarinic and central sedative action. It also exerts a depressant action on hyperstimulated labyrinthine function.
Precaution
Hypotension; pregnancy; lactation; elderly. May impair ability to drive or operate machineries.
Side Effect
Extrapyramidal symptoms sometimes associated with severe depression. Drowsiness, headache, GI upsets, unsteadiness, headache; rarely skin and hypersensitivity reactions, dry mouth, blurred vision, urinary difficulty or retention, constipation and increased gastric reflux, fatigue. Hypolipidaemic effect.
Interaction
Cinnarizine: CNS depressant effect enhanced with alcohol. Action potentiated by domperidone.
Dimenhydrinate: Physically incompatible with aminophylline, hydrocortisone, phenothiazines and some barbiturates in solution.
Potentially Fatal: Potentiates the sedative effects of CNS depressants including alcohol, barbiturates, opioid analgesics, sedatives and neuroleptics. MAOIs, atropine, TCAs enhance antimuscarinic effect. Masks ototoxicity produced by aminoglycoside antibiotics.
