Cas no 90729-42-3 (Carebastine)

Carebastine is a selective, non-sedating antihistamine with potent H1-receptor antagonist properties. It is primarily used in the treatment of allergic conditions, including rhinitis and conjunctivitis, due to its ability to effectively inhibit histamine-mediated inflammatory responses. Carebastine demonstrates high bioavailability and a prolonged duration of action, ensuring sustained therapeutic effects. Its low affinity for central nervous system receptors minimizes drowsiness, a common side effect of first-generation antihistamines. The compound exhibits favorable pharmacokinetics, with rapid absorption and extensive tissue distribution. Carebastine's metabolite, ebastine, further contributes to its efficacy. Its well-characterized safety profile makes it suitable for long-term use in managing chronic allergic disorders.
