Sir, Fexofenadine is the active metabolite of the non-sedating antihistamine, terfenadine. Accumulation of terfenadine can cause prolongation of the QT interval and significant cardiac arrhythmias.1 Fexofenadine is reported to have no potential for QT interval disturbance.2 Phase II and III clinical trials in over 6000 patients showed no mean increases in mean QTc or serious cardiac arrhythmias...
Simultaneous determination of pharmaceutical compounds and accurate quantitative prediction of them are of great interest in the clinical and laboratory-based investigations.This work has focused on a comprehensive comparison of Partial Least-Squares (PLS-1) and Artificial Neural Networks (ANN) as two powerful types of chemometric methods. For this purpose, montelukast (MONT), fexofenadine ...
Both influx and efflux transporters are thought to be involved in the intestinal absorption of fexofenadine. The present study examined the influx transporter-mediated intestinal absorption of fexofenadine in rats, focusing on the role of rat oatp3 (Oatp1a5). The intestinal permeability of fexofenadine was evaluated by means of the Ussing chamber method in the presence of a P-glycoprotein inhib...
The hepatobiliary disposition of xenobiotics may involve passive and/or active uptake, metabolism by cytochromes P450, and excretion of the parent compound and/or metabolite(s) into bile. Although in vitro systems have been used to evaluate these individual processes discretely, mechanistic in vitro studies of the sequential processes of uptake, metabolism, and biliary or basolateral excretion ...
although current guidelines place single leukotriene receptor antagonists use as a therapeutic option in mild persistent asthma, there is still uncertainty about its place. in this study efficiency of montelukast monotherapy in children with moderate persistent asthma was evaluated. children (age 6 to 16) with persistent moderate asthma were treated prospectively with budesonide combined with m...
BACKGROUND Oral antihistamines that target the histamine receptor-1, such as fexofenadine, offer suboptimal relief of allergic rhinitis-associated nasal congestion. Combinations with oral sympathomimetics, such as pseudoephedrine, relieve congestion but produce side effects. Previous animal and human studies with histamine receptor-3 antagonists, such as PF-03654764, demonstrate promise. METH...
This study investigated the effect of multidose administration of danshen ethanol extract on fexofenadine pharmacokinetics in healthy volunteers. A sequential, open-label, two-period pharmacokinetic interaction design was used. 12 healthy male volunteers received a single oral dose of fexofenadine (60 mg) followed by danshen ethanol extract (1 g orally, three times a day) for 10 days, after whi...
a simple, inexpensive and efficient method was used for extraction and determination of fexofenadine and levocetirizine with three–phase hollow fiber liquid-phase microextraction and high-performance liquid chromatography. several parameters influencing the extraction recoveries such as the nature of organic extraction solvent, ph of donor and acceptor phases, stirring rate, extraction time and...
Lack of dose-dependent effects of itraconazole on the pharmacokinetic interaction with fexofenadine.
The aim of this study was to determine the inhibitory effect of itraconazole at different coadministered doses on fexofenadine pharmacokinetics. In a randomized four-phase crossover study, 11 healthy volunteers were administered a 60-mg fexofenadine hydrochloride tablet alone on one occasion (control phase) and with three different doses of 50, 100, and 200 mg of itraconazole simultaneously on ...
