Absorption, distribution, metabolism, and excretion (ADME) properties are of invaluable importance to a bioactive compound. Permeation process is one of the most widely studied by many different techniques. Among them, reversed-phase liquid chromatography (RP-LC) is proving to be of great

A highly sensitive method was developed and validated for determining the free fraction of flunarizine in human plasma. Equilibrium dialysis was used for the separation of free (unbound) drug and liquid chromatography/tandem mass spectrometry (LC-MS/MS) was used for quantitation. Post-dialysis

A sensitive, specific and precise HPLC-UV assay was developed to quantitate cocaine (COC) and its metabolites benzoylecgonine (BE), norcocaine (NC) and cocaethylene (CE) in rat plasma. After adding 50 microl of the internal standard solution (bupivacaine, 8 microg/ml) and 500

A reversed-phase high-performance liquid chromatographic method with electrochemical detection has been developed for the determination of buspirone from human plasma. The separation was carried out by using a Supelcosil ABZ+ plus C18 reversed-phase column and 0.05 M potassium dihydrogenphosphate (pH
A liquid-liquid extraction method using diethyl ether as organic solvent was optimized simultaneously for five 1,4-dihydropyridines (amlodipine, nitrendipine, felodipine, lacidipine and lercanidipine) belonging to the group of calcium channel blockers. Some experimental tools such as a full factorial design, a
