1. Chronic use of Saint John's wort (SJW) has been shown to lower the bioavailability for a variety of co-administered drugs including indinavir, cyclosporin, and digoxin. Decreases in intestinal absorption through induction of the multidrug resistan

Transformation of escitalopram (S-CT), the pharmacologically active S-enantiometer of citalopram, to S-desmethyl-CT (S-DCT), and of S-DCT to S-didesmethyl-CT (S-DDCT), was studied in human liver microsomes and in expressed cytochromes (CYPs). Biotran

The kinetics of flunitrazepam (FNTZ) N-demethylation to desmethylflunitrazepam (DM FNTZ), and 3-hydroxylation to 3-hydroxyflunitrazepam (3-OH FNTZ), were studied in human liver microsomes and in microsomes containing heterologously expressed individu

Since antiretroviral drugs are known to inhibit many cytochrome P450 isoforms, the inhibition of CYP2B6 by non-nucleoside reverse transcriptase inhibitors and viral protease inhibitors was studied in vitro in human liver microsomes using bupropion hy

The in vitro biotransformation of bupropion to hydroxybupropion was studied in human liver microsomes and microsomes containing heterologously expressed human cytochromes P450 (CYP). The mean (+/-S.E.) K(m) in four human liver microsomes was 89 (+/-1

The metabolism of the antidepressant mirtazapine (MIR) was investigated in vitro using human liver microsomes (HLM) and recombinant enzymes. Mean K(m) values (+/-S.D., n = 4) were 136 (+/-44) microM for MIR-hydroxylation, 242 (+/-34) microM for N-dem

Zafirlukast is a cysteinyl leukotriene antagonist used to treat allergic and exercise-induced asthma. This in vitro study used human liver microsomes to evaluate the inhibitory activity of zafirlukast versus six human cytochrome P450 (CYP) isoforms.

Eighteen healthy volunteers (10 men and 8 women) participated in a single-dose, double-blind, three-way crossover pharmacokinetic and pharmacodynamic study. Treatment conditions were 0.25 mg of triazolam, a full-agonist benzodiazepine ligand; 10 mg o

The in vitro biotransformation of sildenafil to its major circulating metabolite, UK-103,320, was studied in human liver microsomes and in microsomes containing heterologously expressed human cytochromes. In human liver microsomes, the mean K(m) (+/-

To study age-related changes in drug metabolism, we examined the in vitro biotransformation of midazolam (MDZ), a human cytochrome P-450 (CYP) 3A substrate, using liver microsomes from three age groups of male CD-1 mice ranging from 6 weeks to 2 year
