A simple and accurate assay for the determination of griseofulvin and its metabolites in biological fluids using high-performance liquid chromatography is described. Using a reversed phase column and a mobile phase solvent of 45% acetonitrile in 0.1 M acetic acid, baseline separation of griseofulvin and several analogues was obtained. The described method(More)
OBJECTIVE To introduce a model treatment algorithm for use in the managed care setting as a strategy to provide ongoing disease management and long-term care for patients with multiple sclerosis (MS), with the goal of delaying disease progression and the associated disability and cognitive dysfunction. SUMMARY MS is a chronic inflammatory disorder of the(More)
Antibiotics represent a relatively high drug cost component for the average institution. There are numerous antibiotic agents available for many indications so the choice of agents for which to provide coverage becomes complicated. The two fluoroquinolones levofloxacin (Levaquin, Ortho-McNeil Pharmaceuticals Inc.) and gatifloxacin (Tequin, Bristol-Myers(More)
To understand hydrazone formation in hydralazine metabolism, the reaction of hydralazine with various biogenic aldehydes and ketones (acetone, pyruvic acid, acetoacetic acid, formaldehyde, and acetaldehyde) in pH 7.4 buffer was studied for potential alterations in hydralazine pharmacokinetics secondary to alcoholism and diabetes. The corresponding(More)
In vitro kinetic studies of the reaction of hydralazine with acetaldehyde at physiological concentrations and pH were conducted. This reaction, which leads to the formation of 3-methyl-S-triazolo[3,4-a]phthalazine, may occur in the plasma and may represent an alternative pathway for hydralazine metabolism. The reaction of hydralazine with acetaldehyde(More)
