What is Claritin?

Claritin is a Brand name for antihistamine drug that contains loratadine as an active ingredient. Loratadine is second generation, non-sedating and long-acting, antihistamine drug that reduces the effects of natural histamine during allergic reactions in the body. Unlike classical first generation antihistamines it does not causes CNS depressing effects such as drowsiness. It is used for relieving the symptoms of hives, skin rash, itching, sneezing, runny nose, watery eyes and other allergy or cold symptoms. Claritin can be also used for the treatment of chronic skin hives and itching. Claritin is available in following dosage forms and strengths: solution (5mg/5ml), syrup (1mg), tablet (10mg), chewable tablet (5mg), orally disintegrated tablet (5 and 10mg), capsule and liquid filled capsule (10mg).

Other products on the market containing loratadine are: Alavert, Claritin Reditab, Clear-Atadine, Dimetapp ND, ohm Allergy Relief, QlearQuil All Day & Night, Tavist ND, Wal-itin.

How does Claritin work in the body?

Loratadine, the active substance of Claritin, is a long acting second generation antihistamine. Loratadine has similar pharmacology effects to other antihistamines, but unlike other H1-antagonists, loratidine has more competitive, specific, and selective antagonism properties for H1 receptors. Exact mechanism of prolonged antihistamine effects is unknown, but it may be because of drug’s slow dissociation from the H1 receptor or because of the formation of its active metabolite desloratidine. Loratadine does not penetrate blood-brain barrier effectively and has a low affinity for H1-receptors in CNS than other antihistamine drugs. Studies showed that loratadine has a low affinity for cholinergic receptors and does not have any significant alpha-adrenergic antagonist in-vitro activity. Loratadine can also suppress the release of histamine and leukotrienes mastocytes in animals, and the release of leukotrienes, however the clinical importance of this is still unknown.
