Coadministration of voriconazole and phenytoin: pharmacokinetic interaction, safety, and toleration.

Aims: Voriconazole is a new triazole antifungal agent, and is metabolized by the cytochrome P450 isoenzymes CYP2C9, CYP2C19, and, to a lesser extent, by CYP3A4. Phenytoin is an inducer of CYP3A4 activity, and a substrate and inducer of CYP2C9 and CYP2C19. The present studies investigated the pharmacokinetic interactions of voriconazole and phenytoin when coadministered.

The pharmacokinetics and safety of intravenous voriconazole - a novel wide-spectrum antifungal agent.

Aims: Voriconazole is a new triazole with broad-spectrum antifungal activity against clinically significant and emerging pathogens. These studies evaluated the pharmacokinetics and safety of intravenous voriconazole in healthy male volunteers.

Methods: Two single-blind, placebo-controlled studies were conducted.

Pharmacokinetics, pharmacodynamics, and safety of the 5-HT(1B/1D) agonist eletriptan following intravenous and oral administration.

Four separate studies were conducted to examine the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of eletriptan, a 5-HT(1B/1D) receptor agonist being developed for the treatment of migraines, after oral and intravenous administration. Fifty-five males received oral (1.5-30 mg or 30-120 mg) or intravenous (1.
