The present study involves preparation and evaluation of floating microspheres with cimetidine as model drug for prolongation of gastric residence time. The microspheres were prepared by the solvent evaporation method using polymers hydroxypropylmethyl cellulose and ethyl cellulose. The shape and surface morphology of prepared microspheres were characterized by optical and scanning electron mic...

The strain of Penicillium janthinellum NCIM 1171 was subjected to mutation involving treatment of Ethyl Methyl Sulfonate (EMS) for 24h followed by UV-irradiation for 3min. Successive mutants showed enhanced cellulase production (EMS-UV-8), clearance zone on Avicel containing plate (SM2) and rapid growth on Walseth cellulose agar plates containing 0.2% 2-deoxy-d-glucose (SM3). These mutants were...

The present study was oriented towards microencapsulation of aspirin and the study of its release kinetics. The desired encapsulation was achieved by emulsion solvent evaporation method using ethyl cellulose (EC), cellulose acetate phthalate (CAP) and their mixture (1:1) of polymeric constituents. Characterization of the formulations was performed by size, shape, drug loading efficiency and in-...

An attempt was made to formulate Buccal patches of Isoxsuprine hydrochloride, a potent and long acting vasodilator and uterine suppressant , by using Hydroxyl propyl methyl cellulose(HPMC), Polyvinyl pyrolidone K-30 (PVP K-30) and Hydroxyl ethyl cellulose (HEC). Twelve batches of buccal patches were prepared by solvent casting technique in which the best formulation was found out. The polymers ...

Ionic liquids (ILs) are promising solvents for the pretreatment of lignocellulose as they are thermally stable, environmentally friendly, recyclable, and have low volatility. This study evaluated the effect of 1-ethyl-3-methylimidazolium acetate ([EMIM][OAc]) for the pretreatment of energy cane bagasse in terms of biomass composition, structural changes and enzymatic digestibility. Energy cane ...

The purpose of the present investigation was to develop a gastro-retentive cilnidipine loaded floating microspheres. microspheres were prepared by solvent evaporation method for oral drug delivery using HPMCK4M and ethyl cellulose as polymers. evaluated particle size, content, entrapment efficiency time. in-vitro study performed in pH 1.2 determine amount released. Field emission scanning elect...

With the emergence of "super bacteria" that are resistant to antibiotics, e.g., methicillin-resistant Staphylococcus aureus, novel antimicrobial therapies are needed to prevent associated hospitalizations and deaths. Bacteriophages and bacteria use cell lytic enzymes to kill host or competing bacteria, respectively, in natural environments. Taking inspiration from nature, we have employed a cel...

The main objective of this study was to develop mebeverine hydrochloride colon targeted drug delivery system using compression coating technique for effective treatment of irritable bowel syndrome. This work was mainly focused on the formulation & in-vitro evaluation of compression coated tablets of mebeverine hydrochloride with different pH dependent polymers like Eudragit L100-55, hydroxyprop...

1. A method is described for the purification of a proteinase, present in human seminal plasma and previously shown to accelerate migration of spermatozoa through cervical mucus in vitro. A 25-fold purification was achieved in three steps, consisting of ammonium sulphate fractionation, chromatography on CM-cellulose and gel filtration. 2. The enzyme displays some properties similar to chymotryp...

the purpose of this research was to formulate and systemically evaluate in-vitro and in-vivo performances of mucoadhesive propranolol hydrochloride microspheres for its potential use in the treatment of hypertension, myocardial infraction and cardiac arrhythmias. propranolol hydrochloride mucoadhesive microspheres, containing carbopol-934p as mucoadhesive polymer and ethyl cellulose as carrier ...
