A long-standing mystery solved: the formation of 3-hydroxydesloratadine is catalyzed by CYP2C8 but prior glucuronidation of desloratadine by UDP-glucuronosyltransferase 2B10 is an obligatory requirement.

Drug metabolism and disposition: the biological fate of chemicals, 43(4), 523-533 (2015-01-18)

Desloratadine (Clarinex), the major active metabolite of loratadine (Claritin), is a nonsedating long-lasting antihistamine that is widely used for the treatment of allergic rhinitis and chronic idiopathic urticaria. For over 20 years, it has remained a mystery as to which

A novel model of IgE-mediated passive pulmonary anaphylaxis in rats.

Eva Wex et al.

PloS one, 9(12), e116166-e116166 (2014-12-30)

Mast cells are central effector cells in allergic asthma and are augmented in the airways of asthma patients. Attenuating mast cell degranulation and with it the early asthmatic response is an important intervention point to inhibit bronchoconstriction, plasma exudation and

Differential thermodynamic driving force of first- and second-generation antihistamines to determine their binding affinity for human H1 receptors.

Shigeru Hishinuma et al.

Biochemical pharmacology, 91(2), 231-241 (2014-07-30)

Differential binding sites for first- and second-generation antihistamines were indicated on the basis of the crystal structure of human histamine H1 receptors. In this study, we evaluated differences between the thermodynamic driving forces of first- and second-generation antihistamines for human

Development and validation of an ultra-performance liquid chromatography method for simultaneous analysis of 20 antihistaminics in dietary supplements.

Jung Yeon Kim et al.

Biomedical chromatography : BMC, 29(3), 465-474 (2014-08-01)

The purpose of this study was to develop and validate an ultra-performance liquid chromatography method for simultaneous analysis of 20 antihistamines (illegal additives) in dietary supplements. The limits of detection and quantitation of the method ranged from 1.5 to 2.5

Utility of cerebrospinal fluid drug concentration as a surrogate for unbound brain concentration in nonhuman primates.

Yoko Nagaya et al.

Drug metabolism and pharmacokinetics, 29(5), 419-426 (2014-05-09)

In central nervous system drug discovery, cerebrospinal fluid (CSF) drug concentration (C(CSF)) has been widely used as a surrogate for unbound brain concentrations (C(u,brain)). However, previous rodent studies demonstrated that when drugs undergo active efflux by transporters, such as P-glycoprotein
