Poly(2-ethyl-2-oxazoline) (PEOX), a biocompatible polymer considered as pseudo polypeptide, was introduced as a potential alternative to the commonly used polymer, poly(vinylpyrrolidone) (PVP) for the preparation of solid dispersion with a poorly soluble drug. Glipizide (GPZ), a BCS class II model drug, was selected for solubility and dissolution rate study. GPZ-polymer solid dispersions and physical mixtures were characterized and investigated by X-Ray diffractometry, differential scanning...

Abstract: Increased complications and costs of marketing of innovative drugs focused greater attention to the development of sustained release (SR) or controlled release (CR) drug delivery systems. Delivery systems extended release or controlled release rate can achieve predictable and reproducible, the extended duration of activity for the short time of life - drugs, reduced toxicity, and dose reduction request, the optimized therapy and better patient compliance. It is controlled primarily by...

The aim of the current study was to formulate and evaluate glipizide controlled release matrix tablets by means of different grades of polymer Ethoceland different co-excipients in order to evaluate their effect on drug release profiles during in vitro dissolution studies. Type II diabetes mellitus is usually treated with Glipizide. Glipizide belongs to sulfonylurea group. Gastric disturbance and severe hypoglycemia has been observed after taking glipizide orally. To overcome these problems,...

Poor water solubility of pharmaceutical candidates creates a big barrier to development and clinical applications. In this study, glipizide as a poorly water soluble drug was precipitated as nanoparticles and processed by spray drying to produce fast dissolving powders. Nanosuspensions of glipizide were prepared using the sonoprecipitation technique in the presence of selected stabilizers. Sorbitol, mannitol, and microcrystalline cellulose (Avicel) were involved in the formulations as the...
