General description

Ebastine is metabolised by cytochrome P450 3A (CYP3A4) to carebastine. It is used to treat allergic rhinitis and chronic idiopathic urticaria.

Application

Ebastine has been used as a cationic amphiphilic drug (CAD) in sensitizing cancerous cells to chemotherapy and revert multidrug resistance.

Biochem/physiol Actions

Ebastine is a non-sedating histamine H1 receptor antagonist, which inhibits allergen-induced bronchospasm in conscious guinea pigs. Unlike other compounds in this category, ebastine does not prolong the QT interval at up to five times the recommended therapeutic dose.

It is well established that cytochrome P450 2J (CYP2J) enzymes are expressed preferentially in the heart, and that ebastine is a substrate for CYP2J, but it is not known whether ebastine is metabolized in myocardium. Therefore, we investigated its pharmacokinetics
