Cefuroxime Axetil is a second generation antibacterial belongs to Cephalosporin Group. The drug undergoes rapid metabolism in intestinal mucosa due to change in pH Environment and hence has decreased oral bioavailability. The aim of present investigation is to increase the gastric residence time by preparing gastroretentive tablets here by improving bioavailability of Cefuroxime Axetil. A simple UV spectrophotometric method has been employed for the estimation of Cefuroxime Axetil at 281 nm. A floating drug delivery system (FDDS) was developed using gas-forming agents, like sodium bicarbonate, sodium alginate and hydrocolloids like hydroxyl propyl methyl cellulose (HPMC) and guggul. The prepared tablets were evaluated in terms of their precompression parameters, physical characteristics, In vitro release, buoyancy lag-time and swelling index. The formulations were optimized for the different grades of HPMC, and its concentrations and combinations. The results of the In vitro release studies showed that the optimized formulation F3 could sustain drug release of 92% and remain buoyant for 10h. The optimized formulation was subjected to various kinetic release investigations and it was found that the mechanism of drug release was predominately Higuhci with non fickian diffusion. Finally the tablets formulations found to be economical and may overcome the draw backs associated with the drug during its absorption.

Hypertension or high blood pressure is a chronic medical condition in which the arterial blood pressure is elevated (normal blood pressure is 120/80 mm Hg). High Blood Pressure may lead to heart failure, stroke, coronary heart disease, kidney failure etc and may affect lungs, brain and heart. It is an important global problem and a very good percentage of people all over the world are affected by blood pressure. As there is no definite cure for this condition, hence controlling it is a big challenge. The main focus on BP management is to lower the elevated blood pressure and to prevent or reduce target organ damage. Although various antihypertensive drugs are available, they are usually associated with many sides –effects. The following article deals with the alternative measures used for lowering high blood pressure giving more importance on the various herbal drugs to be used as combination therapy.

Solubility is one of the essential parameters to achieve bioavailability of drug in systemic circulation to produce expected therapeutic response. Nearly 40% of new drug molecules face solubility challenge. Though several techniques like micronization, crystal engineering, hydrotrophy, solid dispersion and so forth were available for solubility enhancement of poorly soluble drugs based on physical and chemical modification, prodrug approach is a vital technique amongst the other. Prodrugs are biologically inactive compound which can be metabolized in the body to produce active drug. It is estimated that currently about 10% of all world-wide approved drugs are prodrugs. This review extensively confers the role of prodrugs and the kind of promoieties used for solubility enhancement.

Development of new drugs, especially in the area of oncological and infectious disease represents today one of the most important research fields. The marine environment is a tremendous source of natural products. Many new compounds isolated from marine micro- and macroorganisms showed prominent biological effects, mostly antibiotic and cytotoxic activities. The current study aimed to investigate pure compounds which were isolated from marine-derived fungi. The study was preformed with fractions from two marine derived fungal strains, i.e. Verticillium teneru and Acremonium sp. The isolation of the desired secondary metabolites was carried out using different chromatographic separation techniques (TLC, VLC and mainly HPLC). Chemical and spectroscopic methods (1D NMR, 2D NMR, MS, IR and UV) were applied for structural elucidation of the separation compounds. Extracts of two algal-derived fungus strains with high cytotoxic properties, were investigated chemically. This investigation resulted in the isolation and structure elucidation of three pure compounds representing different structural sub-classes, one of them 1 proved to be new natural products and two were known compounds2 & 3.

Plants have been used in treating cardiovascular diseases (CVD) and are recognized for their ability to produce secondary metabolites. Secondary metabolites obtained from different plants have been the starting material for designing different drugs. Echinosystic acid, a pentacyclic triterpene was isolated and identified from the fruits of Gleditsia sinensis Lam. Echinosystic acid has significant cardioprotective effects. Different phytochemicals have been found to be cardioprotective and paved the path towards development of cardioprotective formulations. In the present study we have analyzed the inhibitory potential of Echinosystic acid, on the Angiotensin Converting Enzyme (ACE) - the enzyme responsible for various cardiovascular diseases.
The study revealed that Echinosystic acidhave high ACE inhibiting potential as compared to other known ACE inhibitors.

Microspheres are well accepted technique to control the drug release from the dosage form to improve bioavailability, reduce absorption difference in patients, reduce the dosing frequency and adverse effects during prolong treatment. The main objective of the present study is to prepare and evaluate ibuprofen microspheres by solvent evaporation method, with water insoluble polymers such as Ethyl cellulose and sodium carboxymethyl cellulose as suspending agent, using as carrier for oral administration in view to achieve oral sustained release of the drug. Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID) used for relief of signs and symptoms of rheumatoid arthritis, osteoarthritis and is used in chronic and acute conditions of pain and inflammation. Its biological half-life is 2 ±0.5 hrs. Due to its low biological half-life (2 hrs), it requires frequent administration to maintain plasma concentration. This causes inconvenience to the patient and also leads fluctuations in plasma drug concentration that may cause inferior therapeutic effects or toxic effects. There-fore, development of controlled release dosage forms would clearly be beneficial in terms of decreased dosage requirements, thus increase patient compliance. The formulations were evaluated for particle size distribution analysis, flow properties like Angle of repose, bulk density, tapped density, Hausner’s Ratio, Carr’s index, Encapsulation efficiency, Scanning electron microscopy,optical electron microscopy and invitro release studies. The optimized formulation showed good invitro sustained release activity of the drug ibuprofen.
