Description
Cinarin's actions in the treatment of peripheral vascular disease are due to its anti-vasoconstrictor properties, its action on blood hyperviscosity and its anti-ischaemic effect. Anti-vasoconstriction is thought to be through a calcium blocker mechanism and is evident selectively in vascular smooth muscle. Increased peripheral muscle blood flow may be mediated by prevention of calcium entry into ischaemic erythrocytes, thereby prescribing flexibility.
Pharmacology
Cinnarizine acts as an antihistamine, labyrinthine sedative and a peripheral antivasoconstrictor. Cinnarizine is a selective calcium antagonist, inhibiting the influx of Ca2+ intracellularly. It prevents the Ca2+ dependent contraction of arterial smooth muscle by inhibiting Ca2+ influx through smooth muscle calcium channels and thereby, improves vestibular symptoms and prevents peripheral arterial disease
Dosage & Administration

Children (5 to 12 years): Half of the adult dose.

Interaction
No drug interactions have been seen with Cinarin when administered concomitantly with antihypertensives, diuretics, anticoagulants or hypoglycaemics.
Contraindications
There are no specific contraindications. It has been found to decrease blood pressure significantly. However, the drug should be used with reasonable caution in hypotensive patients.
Side Effects
Side effects such as somnolence and gastrointestinal disturbances are extremely rare. They are transient and may be readily prevented by achieving the optimal dosage gradually. Allergic skin reactions and fatigue have been reported on rare occasions. An aggravation or appearance of extrapyramidal symptoms has been reported extremely rarely in elderly people during prolonged therapy. The treatment should be reduced or stopped in such cases.
Pregnancy & Lactation
The safety of Cinnarizine in human pregnancy has not been established although studies in animals have not demonstrated teratogenic effects. Therefore, it is not advisable to administer Cinnarizine in pregnancy
Precautions & Warnings
