Os polihidroxialcanoatos são poliésteres de hidroxiácidos sintetizados por inúmeras bactérias, como compostos que servem como fonte de carbono intracelular e energia, sendo acumulados na forma de grânulos no cito...

To select the suitable concentration level of controlled release polymer for the formulation of predefined extended release formulation based on the solubility behaviour of active substance, we have formulated and evalua...

The aim of this study was to develop topical hydrogels containing diclofenac potassium (DP) at 1 % w/v concentration using conventional hydrophilic hydroxypropyl methyl cellulose (HPMC, 50cPs) and modified hydrophobic ...

The aim of this study was to formulate gliclazide loaded controlled release microspheres. Microspheres were prepared by quasi emulsion solvent diffusion technique using eudragit RLPO, eudragit RSPO and with their various...

This study introduced a novel phase separation technique for the microencapsulation of metoprolol tartrate as a model. Non-solvent addition coacervation technique was employed for the loading of drug into ethylcellulose,...

En los últimos años, se ha desarrollado un gran interés por la producción de polímeros denominados funcionales o specialties. Los mismos se destacan por poseer algunas propiedades particulares que dan lugar a aplica...

Solid dispersions (SDs) of poorly water soluble diacerein were prepared with polyvinylpyrrolidone K30 at drug to polymer ratios of 1:1, 1:3 and 1:5 w/w utilizing kneading technique. Physical mixture (PM) was prepared at ...

The present study involves preparation and characterization of floating multiparticulate microcapsules with Simvastatin as model drug for prolongation of gastric residence time. The main objective is to improve solubilit...

The present study was undertaken to investigate the effect of nature of polymers like HPMC, carbopol-934P and their content levels on the release profiles of water soluble drug, diclofenac potassium. For this purpose, di...

A novel polymer, chemically modified chitosan was synthesized by reacting with hydrochloride salt of 2-aminoethanoyl chloride. Formation of novel chemically modified chitosan was confirmed by FTIR and NMR spectroscopy an...

The deposition of chlorhexidine base on thermosensitive N-isopropylacrylamide polymeric microparticles was assessed in this study using energy dispersive X-ray spectrometry (EDXS) in scanning electron microscopy (SEM) se...

Transdermal drug delivery systems of venlafaxine hydrochloride were prepared by using combination of hydrophilic (HPMC E15) and hydrophobic (ERS100 and ERL 100) polymers in 1:5, 2:4, 3:3, 4:2, 5:1 ratios by solvent casti...
