The anti-allergic properties of the drug Cetrin are due to the content of such a component as cetirizine. This substance is a histamine antagonist. The drug of the same name, Cetirizine is on the list of essentials.

Cetrine is available in tablets and syrup by the Indian company Dr. Reddy’s Laboratories. The latest generation anti-allergic drug alleviates allergies, has antiexudative and antipruritic effects, prevents the appearance of edema.

Much of the effectiveness of cetirizine medications depends on bioavailability. Release of Cetrin in 30 minutes is 40.2%, which is good.
