Abstract The present study introduces an overview of gentamicin-clay mineral systems for applications in biomedicine and then focuses on the development a series gentamicin/clay hybrid materials to be used as bioactive phase hydroxypropylmethylcellulose (HPMC) produce bionanocomposite membranes possessing antimicrobial activity interest wound-dressing applications. Gentamicin (Gt) was adsorbed ...

Antibacterial SiO2 hybrid materials based on tetraethyl orthosilicate (TEOS), hydroxypropylmethylcellulose (HPMC) and silver were prepared by the sol-gel method. The content of cellulose derivate was 5 wt% and the silver concentration varied from 0.5 wt% to 2.5 wt%. The amorphous nature, morphology and antibacterial behaviour were studied. Fourier transform infrared (FTIR) spectra of the hybrid...

The aim of the present study was the determination of formulation factors and the in vitro evaluation of an extended release dosage form of a freely soluble weakly basic drug (alfuzosin hydrochloride). Binary mixer of one hydrophilic polymer (hydroxypropylmethylcellulose) and one directly compressible Eudragit (RS PO) was used in tablets prepared by direct compression. The amounts of both polym...

In the present investigation, an attempt has been made to increase therapeutic efficacy, reduce frequency of administration and improve patient compliance by developing sustained release matrix tablets of theophylline. Sustained release matrix tablets of theophylline were developed by using drug and different concentrations of polymer such as 10, 20, 30, 40 and 50%. Hydroxypropylmethylcellulose...

The ability of high viscosity hydroxypropylmethylcellulose (HPMC) to reduce postprandial glucose concentrations was assessed in patients with non-insulin-dependent diabetes (NIDDM) and healthy volunteers. The study design consisted of a two-way crossover, single-dose administration of 10 g prehydrated high viscosity HPMC, or placebo, with a standard carbohydrate-rich meal. In patients with NIDD...
