Desloratadine is an antihistamine used to relieve allergy symptoms. It is a non-sedating oral medication that blocks the action of histamine, a substance the body produces during an allergic reaction [1].
What kind of medication is Desloratadine?
Desloratadine is classified as a second-generation antihistamine. Unlike older antihistamines, it is designed to be less likely to cause drowsiness because it does not readily cross the blood-brain barrier [2].
How does Desloratadine work for allergies?
Desloratadine works by selectively blocking histamine H1 receptors in the body. Histamine is released when the body encounters an allergen, and it binds to these receptors, causing symptoms like itching, sneezing, runny nose, and watery eyes. By blocking these receptors, desloratadine prevents histamine from exerting its effects, thereby alleviating allergy symptoms [1][3].
What symptoms does Desloratadine treat?
Desloratadine is indicated for the symptomatic relief of allergic rhinitis, which includes symptoms such as sneezing, nasal discharge, itching, and nasal congestion. It is also used to relieve chronic urticaria (hives), including associated itching and redness [1][3].
When does patent exclusivity for Desloratadine expire?
