Desloratadine is a tricyclic H1-antihistamine that is used to treat allergies. It is an active metabolite of loratadine.
Use
Desloratadine is used to treat allergic rhinitis and nasal congestion.[1] It is the major metabolite of loratadine and the two drugs are similar in safety and effectiveness.[1]
Side effects
Most common side-effects are fatigue, dry mouth, headache, and gastrointestinal disturbances.[1]
Mechanism of action
Desloratadine is a selective H1-antihistamine which functions as an inverse agonist at the histamine H1 receptor;[2] it is also an antagonist at all subtypes of the muscarinic acetylcholine receptors. It has a long-lasting effect and is effective in moderate and low doses. It exhibits only peripheral activity since it does not readily cross the blood-brain barrier; hence, it does not cause drowsiness because it does not readily enter the central nervous system.[3]
Society and culture
Desloratadine is available in many dosage forms and under many trade names worldwide.[4]
