The objective of the study is to make a pharmacokinetic evaluation of Pioglitazone floating tablets formulated employing HPMC K 15 M in comparison to Pioglitazone pure drug in rabbits. The two products were tested in a crossover RBD in healthy rabbits of either sex (n=6). The plasma concentrations of Pioglitazone were determined by a validated HPLC method. From the time versus plasma concentration data, various pharmacokinetic parameters (Cmax, Tmax, t1/2, AUC, Ka, and MRT) were calculated. Pioglitazone from the floating tablets formulated was absorbed slowly over longer periods in-vivo resulting in the maintenance of plasma concentrations within a narrow range over a longer period. The absorption rate constant (Ka) was decreased from 1.462 h-1 for Pioglitazone pure drug to 0.1598 h-1 with the floating tablets. MRT was increased from 9.82 h for Pioglitazone pure drug to 13.30 h with the floating tablets. There was no increase in the bioavailability of Pioglitazone from the floating tablets...

The present study investigated the protective role of methanolic extract from Anethum graveolense L. (AGME) on bile duct ligation (BDL) produce hepatic fibrosis in the rat. BDL rats were divided into four groups, which received orally distilled water or AGME (200 and 400 mg/kg) for continuously 28 days. The BDL induced hepatic fibrosis by anti-fibrotic effect of AGME in the rats determined by serum level of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBL), direct bilirubin (DBL), alkaline phosphatase (ALP), creatinine (CRT), glucose (GLU), triglycerides (TGL), cholesterol (CHOL), total protein (TP), albumin (ALB), transforming growth factor beta-1 (TGF-β1) and oxidative parameter like glutathione (GSH), malondialdehyde (MDA), total superoxide dismutase (SOD) and nitric oxide (NO) level. Biochemical estimation was complemented by histopathological measurement of the liver. Phytochemical in AGME were determined by qualitative and high-performance liquid chromatography (HPLC) analysis. All the serological level was elevated on treated with BDL group alone than in the sham control group (P<0.01). Treatment with AGME these elevations was mostly diminished. Also, increase in...

The concept of fast dissolving drug delivery system emerged from the desire to provide patients with more convenient means of taking their medication. It is difficult for many patients to swallow tablets and hard gelatin capsules. The main objective of the study is to develop a reproducible formulation of fast dissolving tablets of Lornoxicam already used the therapeutic molecule to enhance effectiveness and to avoid side effects (gastric irritation) of the drug. Different batches of tablets were prepared by direct compression method using a different concentration of superdisintegrants like gum karaya, chitosan, and fenugreek seed mucilage powder. Before compression pre-formulation studies were done which includes characterization of the blend and physical compatibility studies with excipients. Effect of change in super disintegrant and their concentration on the formulation was studied. Final batches were compared for the superiority of superdisintegrants in the formulation of MDT of Lornoxicam. Tablets were evaluated for weight variation, thickness, hardness, friability, drug content, in-vitro disintegrating time and in-vitro drug...

This paper describes a new validated Reverse-Phase High-Performance Liquid Chromatography (HPLC) method for the simultaneous determination of two anti-cancer drugs, Daunorubicin and Cytarabine (Ara-C). A simultaneous determination method saves cost and time as both drugs can be injected into a single HPLC system without the need to change or re-equilibrate with a new mobile phase. The objective of the study is to develop a simultaneous determination method of two anti-cancer drugs, Daunorubicin and Cytarabine. The mobile phase consists of a mixture (55:45 v/v) of 0.1% OPA: acetonitrile at a flow rate of 0.8 ml/min, with a PDA detector at 240 nm. Separation was achieved on a kromosil C-18 column (5 µm; 250 mm × 4.6 mm) maintained at 30 °C temperature in a column oven. The method was linear between 7.25 µg/mL – 43.5 µg/mL for Daunorubicin and 16.2 µg/Ml – 97.5 µg/mL for Cytarabine. The limit of detection was 0.29 µg/mL for Daunorubicin, and 1.15 µg/mL for Cytarabine and the limit of quantification was 0.88 µg/mL for Daunorubicin...

The objective of this work was to formulate and characterize microparticles containing piperine, and evaluate their activity against carbon tetrachloride (CCl4)-induced liver toxicity. Piperine microparticles were formulated by o/w emulsion solvent evaporation technique using poly-ε-caprolactone as a polymer. Four different microparticle formulations (PM1, PM2, PM3, and PM4) were prepared by varying the drug/polymer ratio. The particles were characterized for particle size, drug content, surface morphology, and in-vitro drug release. The pharmacokinetics and pharmacodynamics of the piperine formulations in male Wistar rats were evaluated following intraperitoneal administration, using piperine solution as reference. The hepatoprotective activity of the formulation was determined in a CCl4-treated rat model and also compared with piperine solution. Piperine microparticles were successfully prepared using o/w emulsion solvent evaporation technique. The microparticles sustained the release of the drug both in-vitro and in-vivo for up to 10 days and offered better pharmacokinetic properties than the free drug itself. Microparticle formulation tested in-vivo demonstrated better pharmacokinetics and pharmacodynamics compared to the reference. Drug levels in the liver were significantly higher...
