Ezetimibe (EZT) is the selective cholesterol absorption inhibitor. It is indicated for the treatment of primary hypercholesterolemia. The current investigation was aimed to formulation and evaluation of self nanoemulsifying powder (SNEP) for EZT to enhance solubility and dissolution rate and this will leads to minimize the variability in absorption. Solubility of drug was determined in differen...

The present work deals with the spherical crystallization process by Spherical agglomeration method applied to Zaltoprofen, a novel NSAID drug. The object of present study was to prepare and characterize the spherical agglomeration of water insoluble non-steroidal anti-inflammatory drug. Zaltoprofen spherical agglomerates prepared with poly ethylene glycol, which is hydrophilic polymer by using...

AIM In the present investigation, vancomycin (VCM) biodegradable nanoparticles were developed for oral administration, with the aim of improving its intestinal permeability. METHODS The vancomycin-loaded nanoparticles were prepared using double-emulsion solvent evaporation method. The prepared nanoparticles were characterized for their micromeritic and crystallographic properties, particle si...

Spherical crystallization is a novel particle engineering/design technique developed by Kawashima et al, to overcome the problems associated with direct compression. Basically, it's single step process used for size enlargement of single, two or more, small dose or large dose drugs, in combination with or without diluent. The process of spherical crystallization involves simultaneous crystalliz...

An attempt was made to sustain the release of Betahistine hydrochloride by complexation technique using strong cation-exchange resin, Tulsion T344. The drug loading onto ion-exchange resin was optimized for mixing time, activation, effect of pH, swelling time, ratio of drug : resin, and temperature. The resinate was evaluated for micromeritic properties and characterized using XRPD and IR. For ...

In the present study controlled release formulation of Indomethacin microsponges were prepared by using Eudragit RS 100, pH independent release retardant polymer and PVA, stabilizer or emulsifier. Microsponges were prepared by Quasi emulsion solvent diffusion method by changing drug polymer ratio (3:1, 4:1, 5:1) and process was optimized. Microsponges were evaluated by micromeritic properties, ...

The objective of this study was the preparation ionically crosslinked 6-mercaptopurine (6-MP) monohydrate microparticles through preparing polyelectrolyte complexes drug and polymers. Polymers such as chitosan, casein, carrageenan were used to prepare microparticles, sodium tripolyphosphate crosslinker. Microparticles characterized for their flow behavior, compressibility, percentage yield, mic...

Spherical crystallization of drugs is the process of obtaining larger particles by agglomeration during crystallization. The most common techniques used to obtain such particles are spherical agglomeration and quasi-emulsion solvent diffusion. Ammonia diffusion systems and crystallo-co-agglomeration are extensions of these techniques. By controlling process parameters during crystallization, su...
