Loratadine, tablets 10 mg 10 pcs

Pharmacodynamics

Loratadine is a tricyclic compound with pronounced antihistamine action and is a selective blocker of peripheral H1-histamine receptors. It has a rapid and prolonged antiallergic effect. Onset of action is within 30 minutes after ingestion. Antihistamine effect reaches its maximum after 8-12 hours from the beginning of action and lasts for more than 24 hours.

Pharmacokinetics

Loratadine is quickly and well absorbed in the gastrointestinal tract. Time to reach maximum concentration (Tmax) of loratadine in blood plasma is 1-1.5 hours, and its active metabolite desloratadine – 1.5-3.7 hours. Food intake increases Tmax of loratadine and desloratadine by approximately 1 hour, but has no effect on the effectiveness of the drug.
