CYP2C9 is mainly responsible for the metabolic clearance of phenytoin and (S)-warfarin. We have shown previously that mutations in the CYP2C9 gene are associated with diminished metabolism of (S)-warfarin, and so we have now studied the metabolism of phenytoin to its primary inactive metabolite, (S)-pHPPH, by these mutant enzymes. Kinetic parameters were(More)
Solid lipid nanoparticle is an efficient lipid based drug delivery system which can enhance the bioavailability of poorly water soluble drugs. Efavirenz is a highly lipophilic drug from nonnucleoside inhibitor category for treatment of HIV. Present work illustrates development of an SLN formulation for Efavirenz with increased bioavailability. At first,(More)
A model using SWV mice was developed to investigate the mechanistic basis of carbamazepine (CBZ)-related fetotoxicity. Drug administration was initiated prior to conception and continued until day 18 of gestation. The incidence of malformation was 33% following CBZ exposure (1,500 mg/kg/day), compared with a 5% incidence in pair-fed control animals (P <(More)
Amphotericin B (AmB) is a poorly water soluble polyene antifungal antibiotic which is negligibly absorbed from the gastro intestinal tract after oral administration. The objective of this research work was to study the oral bioavailability and stability of a self-emulsifying drug delivery system (SEDDS) of amphotericin B (AmB). The SEDDS formulation(More)
The objective of present study is to determine the permeation of Pregabalin from transdermal patch into microcirculation of skin. Matrix type transdermal drug delivery system (TDDS) of Pregabalin was prepared by the solvent evaporation technique. Several batches were prepared by using combination of HPMC and PVP; PVA and PVP; Eudragit RL-100 and Eudragit(More)
The present investigation was taken up to prepare and evaluate a transdermal drug delivery system (patch) of Raloxifene Hydrochloride to increase its bioavailability. The matrix type patches were prepared using different ratios of Eudragit RL100, Poly vinyl Pyrrolidone K-30, HPMC, CAP and PEG6000 in different ratios. All the prepared formulations were(More)
OBJECTIVE Ibuprofen is an established non-steroidal anti-inflammatory drug commonly used for general inflammation. However, it causes gastrointestinal troubles when administered orally, thereby decreasing patient compliance. Transdermal application of vesicular formulation of Ibuprofen will provide better patient compliance and efficacy. METHODS Six(More)
The aim of the investigation is to improve the dissolution, wettability, and micromeritic behavior of domperidone, a dopamine antagonist, used in the treatment of nausea and vomiting. Micropelletization technique, a possible approach for ensuring maximum dissolution with enhanced wettability, and uniform pellet size almost spherical so as to achieve the(More)
PURPOSE Previous studies have suggested that polytherapy by design may aid in the management of human pregnancies complicated by epilepsy. However, mechanistic parallels must be drawn between the models of teratogenesis and human pregnancies, and doses of the second agent given to minimize side-effects must be justified. This study sought to determine the(More)
