DEVELOPMENT AND VALIDATION OF RP-HPLC METHOD FOR SIMULTANEOUS ESTIMATION OF CEFPODOXIME PROXETIL AND LEVOFLOXACIN HEMIHYDRATE IN COMBINED DOSAGE FORM
A simple, accurate, precise, rapid and economical RP-HPLC method was developed for the estimation of Cefpodoxime Proxetil (CPD) and Levofloxacin hemihydrate (LVX) in tablet dosage form. In Agilent – 1100/1200 Series, using C18 (250 x 4.6 mm x 5μ) column and with mobile phase composition of Phosphate buffer: Acetonitrile (pH 6.0) (50:50 v/v) at a flow rate of 1 ml/min was used. Detection was car...

GENETIC VARIABILITY OF CYP2B6 G516T AND THEIR IMPACT IN EFAVIRENZ BASED HAART: A META-ANALYSIS
Background: The non-nucleoside reverse transcriptase inhibitor efavirenz is recommended as part of first-line therapy in HIV-infected patients and prescribed at a standard dose of 600 mg once daily. EFV is extensively metabolized primarily by hepatic CYP2B6 with partial involvement of CYP3A4 and CYP2A6. The aim of the study was to assess CYP 2B6 G516T polymorphism and their impact in efavirenz bas...

IN VITRO EVALUATION OF ANTIOXIDANT ACTIVITY AND TOTAL PHENOLIC CONTENT OF METHANOLIC EXTRACT OF PIPER BETEL
The Piper betel is an evergreen and perennial creeper belonging to the Piperaceae family, with glossy heart-shaped leaves and white catkin. It is valued both as a mild stimulant and for its medicinal properties. The total phenolic content of methanolic leaves extract was estimated by Folin-Ciocalteu assay method, and was found to be 0.110 mg/CE/g (Catechine Equivalent per gram). However, anti...

DETERMINATION OF TOLTERODINE TARTRATE IN PHARMACEUTICAL PREPARATIONS USING EOSIN, APPLICATION TO STABILITY STUDY
Spectrophotometric method has been developed for the determination of Tolterodine tartrate (TOL) which is based on formation of a binary complex between TOL and eosin at 545 nm using acetate buffer at pH 3.8.The absorbance-concentration plot is rectilinear over the range (1-10μg/ml) with LOD of 0.1μg/ml and LOQ of 0.31μg/ml. The proposed method was successfully applied to the analysis of commer...

INDUCED COAGULATION AS A COMPLICATION OF INFLAMMATORY REACTIONS IN MICE TREATED WITH MONOSODIUM GLUTAMATE
Monosodium glutamate (MSG) is a familiar food additive processed to enhance the taste. This work was carried out to investigate the effect of MSG on platelets profile and indices of thrombus formation together with the detection of some plasma inflammatory markers. The study used adult male mice divided into five groups: a control group and four groups treated with different doses of MSG (2, 4, 8 ...

SUB-CHRONIC TOXICOLOGICAL INVESTIGATION OF GMELINA ARBOREA (VERBENACEAE) IN HEALTHY WISTAR RATS
The study was designed to determine the acute and sub-chronic toxic effects of aqueous extract of Gmelina arborea (Roxb.) in healthy male Wistar rats. An aqueous bark extract of G. arborea was administered at graded doses (0.25-2.00 g/kg) to Wistar rats in the acute toxicity test. Sub-chronic toxicity was evaluated by daily administration of the extract at 1.00 g/kg to Wistar rats for 30 days. All...

THE EFFECT OF ELICITORS ON THE PRODUCTION OF VASICINE FROM JUSTICIA ADHATODA L. CELL SUSPENSION CULTURES
In this study, α-naphthyl acetic acid and mannitol were used as elicitors to improve the productivity of useful metabolite, vasicine for archiving high concentration in Justicia adhatoda L. cell suspension cultures. When the cells were treated with 3mg 100 ml-1 suspension of α-naphthyl acetic acid, the vasicine concentration was increased by 1.65 mg ml-1 in 15 days culture compared to untrea...
