Quality by Design (QbD) is a systematic approach for the development of products and processes. Azilsartan Medoxomil is a competitive antagonist of the Angiotensin II Type 1 receptor. A precise and reproducible ultra-performance liquid chromatographic (UPLC) method was developed and validated for the estimation of Azilsartan Medoxomil from its marketed tablet dosage form applying Quality by Design approach. Eight experiments were conducted using the full factorial design in order to rationally examine the effects of stationary phase, buffer pH and organic phase concentration in primary screening followed by method optimization with variation in Column temperature and flow rate. Chromatographic separation of AZIL was achieved at 40 °C temperature using an Acquity UPLC BEH C18 (4.6mm × 2.1mm, 1.7μ) analytical column; the mobile phase consisted of Acetonitrile: phosphate buffer (pH 5.5, 0.02mM) (40:60, v/v) at a flow rate of 0.3 ml min-1. Azilsartan eluted with retention time (Rt value) 2.41 min. The linear regression analysis showed good linear relationship with a correlation coefficient of 0.999. The limit of detection and...

The aim is to design, develop & characterize a desired gastro retentive super porous hydrogel (SPH) formulations containing lafutidine is histamine H2-receptor antagonist that may be used alone or with other agents to treat inhibits stomach acid production. SPH‘s synthesized employing various composite agents viz., sodium alginate, pectin, Carbopol, and chitosan were subjected to density and swelling property (swelling time, swelling ratio) characterization. Pectin, Carbapol, and chitosan have shown the best results; they were optimized for further characterization. As a hybrid agent is responsible for maintaining the capillary structure required for fast swelling of SPH, the effect of optimized hybrid on mechanical characters and swelling behavior of SPH was assessed. As the hybrid chitosan concentration increased, there was an extensive variation in swelling properties. Swelling time was gradually decreased from 45 to 16 min. SPHH-CN1 to SPH-CN7 lafutidine combined formulations were developed with dried SPH-CN5 powder. Drug release studies for formulations F1- F7 was carried out, and based upon release and retarding capacity, the effect of sodium bicarbonate F4...

Background: The liver is the major detoxification organ that deactivates and removes toxic chemicals. The oxidative stress-mediated toxicity of chemicals involves destruction primarily to liver tissue (Hepatotoxicity), which could lead to cancer. Diosgenin, a steroidal sapogenin, is reported to be an apoptosis inducer, antineoplastic and antioxidant. The present study is aimed to screen diosgenin for its effect on diethylnitrosamine induced hepatotoxicity in rats. Materials and Methods: 48 male Wistar rats were divided into 6 groups of 8 animals each. Group 1: the vehicle was given to the animals for 8 weeks. Group 2: den control, group 3 sorafenib, groups 4, 5, and 6 diosgenin (10, 20, and 40 mg/kg, respectively). Groups 2 to 6 were administered with 0.01% den in drinking water for 8 weeks. The respective treatment started from 4th week and continued till the 11th week. At the end of the study, animals were sacrificed for the determination of biochemical, antioxidant, and histological parameters. Results: Administration of den caused a significant increase in the levels of serum...

Filicium decipiens belongs to the Sapindaceae family, which is commonly known as fern tree, is found in the Western Ghats of southern India, small highland areas of East Africa and Sri Lanka and it is a medium to a large evergreen tree. It is commonly cultivated in gardens and roadsides as ornamental, noise barriers and windbreak plant. Filicium decipiens traditionally used for the treatment of diabetes in India. The leaves of Filicium decipiens have been collected from the Western Ghats of southern India, shade dried and powdered well. The finely powdered leaves have been extracted with petroleum ether, chloroform, methanol and water successively with an increase in polarity. The methanolic extract was column chromate-graphed using silica gel G 100-200 mesh to get brown color crystalline solid, which was analyzed for the presence of bioactive chemical constituents using Gas chromatography-mass spectrometry (GC-MS) technique. GC-MS analysis revealed the presence of thirty chemical constituents. The four different crude extracts (petroleum ether, chloroform, methanol and water) of leaves of Filicium decipiens have been...

The present study aimed to determine the pharmacognostical evaluation and phytochemical analysis of the plant part of Lagersreomia speciosa. In this study, a macroscopical, microscopical evaluation was done. Various quantitative parameters such as total ash, acid insoluble ash, water-soluble ash sulphated ash, extractive value with various solvent were done. In the preliminary phytochemical analysis, various chemical test were performed for the determination of phytoconstituents present in the plant. Fluorescence analysis of powder drugs was done in a deferent wavelengthrange. TLC was performing for the methanolic extract taking the solvent system with various ratios. From the experiment result it was found leaves are bitter in taste, the shape is elliptical to oblong, acute base subacute apex, entire margin and pinnate venation the leaves are dorsiventral, long epidermis layer, spongy mesophyll, loosely packed parenchyma cell present in the leaf. Microscopic powder drug analysis shows the prism and rosette shape calcium oxalate crystals, lignified and annular xylem vessels, and multicellular trichomes. From quantitative microscopic study stomatal number, vain-islet number, vein termination number...
