the purpose of this work was to develop once daily sustained release (sr) matrix tablets of naproxen, an anti-inflammatory agent. the tablets were prepared by wet granulation method along with hydrophilic matrix materials like methocel k 15m cr and methocel k 100m cr. the granules were evaluated for bulk density, angle of repose, compressibility index, total porosity and drug content. the table...

The goal of this study was to design and evaluate extended - release system of the hypnotic agent, Zolpidemtartrate usefulness for the treatment of insomnia. The half-life of this drug is about 1.9 - 3 hours that indicatingit a candidate for the extended release formulation. Our investigation relates to development of extendeddrug delivery system based on Hydroxy propyl methyl cellulose (HPMCK4...

background the treatment of posterior eye diseases is always challenging mainly due to inaccessibility of the region. many drugs are currently delivered by repeated intraocular injections. objectives the purpose of this study was to investigate the potential applications of natural triglycerides as alternative carriers to synthetic polymers in terms of drug release profile and also biocompatibi...

The aim of this study was to prepare dry powder inhalers (DPIs) containing amphotericin B-loaded solid lipid nanoparticles (AMB-SLNs) as an alternative approach for prevention of pulmonary aspergillosis. For solubilizing AMB in small amounts of organic solvents ion paired complexes were firstly formed by establishing electrostatic interaction between AMB and distearoyl phosphatidylglycerol (DSP...

Diclofenac sodium as ophthalmic dosage form is used in patients treatment of eye pain, swelling and redness recovering from cataract surgery but it faces the bioavailability limitation of eye drops due to effective protective mechanisms and corneal barrier functions in the eyes. Therefore, this investigation was aimed to develop ocular film formulations to achieve controlled drug release. Drug ...

The aim of the present work was to prepare and characterize biopolymer nanocarriers and evaluate their suitability in possible oral delivery of insulin. The egg albumin biopolymer was used to prepare nanoparticles which were further characterized by Fourier transformed Infrared spectroscopy (FTIR), transmission electron microscopy (TEM), scanning electron microscopy (SEM), zeta potential, Dynam...

background to current knowledge, different oocyte's recovery method and various seasons have profound impact on in vitro embryo production (ivep). objectives the aim of this study was to define an efficient recovery method for oocytes harvesting from slaughterhouse material in different seasons, and their effects on ivep yield. materials and methods ovaries from slaughtered ewes in breeding sea...

the aim of the present study was to prepare and evaluate an osmotically controlled mucoadhesive cup-core (ocmc) containing aceclofenac. a special technique was used while preparing an ocmc. stability of ocmc was determined in natural human saliva, and it was found that both ph and device are stable in human saliva. ocmc was evaluated by weight uniformity, thickness, hardness, friability, swelli...
