Bioequivalence Study of Two Oral-Capsule Formulations of Pregabalin 300 mg in Healthy Mexican Adult Volunteers
Pregabalin is a ligand for the alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system. It has anticonvulsant, analgesic, and anxiolytic activity. The bioequivalence of a test formulation was evaluated with respect to its corresponding reference drug formulation of oral pregabalin 300 mg, administered as a capsule. This randomized-sequence, single-dose, single-blind, two-period crossover design under fasting conditions was done on 25 healthy Mexican adult subjects including both genders. There was a seven-day washout period.
Identification of Designer Drugs using Gas Chromatography High-Resolution Mass Spectrometry and a Soft-Ionization Source
Gas chromatography-mass spectrometry (GC-MS) with electron ionization (EI) or chemical ionization (in positive or negative mode) plays an important role in the forensic analysis of designer drugs.
Development of a Stability Indicating UPLC-MS/MS Method for Rapid and Reliable Determination of Fenofibrate in Marketed Product (Lypanthyl® 200M) and Human Plasma
A reliable, fast, sensitive and selective Ultra Performance Liquid Chromatography-Tandem Mass Spectrometry (UPLC-MS/MS) method has been developed and validated for the determination of fenofibrate in marketed product (Lipanthyl) and human plasma. The chromatographic separation was performed on a reversed-phase Acquity®BEH C18 column (1.7 μm particle size, 50 mm x 2.1 mm ID) with an isocratic elution profile and mobile phase consisting of methanol and water (80:20, %, v/v). To achieve optimum chromatographic condition the influence of mobile phase composition and flow rate was investigated. The total chromatographic analysis time was as short as 2 min.
