Formulation Design and Pharmacodynamic evaluation of Alginate microspheres of Olanzepine.

Formulation Development and Evaluation of Alginate Microspheres of Ibuprofen

The present study was designed to investigate the effects of different variables on the release profile of ibuprofen microspheres formulated using modified emulsification method. Eight batches of microspheres (F1-F8) were prepared by applying 2(3) factorial design. The amount of sodium alginate, amount of calcium chloride, and amount of magnesium stearate were selected as formulation variables....

Formulation and Evaluation of Magnetic Microspheres Of Cytarabine

Cytarabine is the drug of choice for treatment of leukemia. However, many formulations have been prepared, due to certain limitations they could not prove to be effective ones, therefore magnetic microspheres are formulated as they minimize the Reticuloendothelial clearance and target site specificity can be increased. The current study aimed to utilize nanotechnology to develop magnetic micros...

Formulation and Evaluation of Solid Dispersion of Olanzepine

Formulation and Evaluation of Solid Dispersion of Olanzepine

The poor dissolution rate of water-insoluble drugs is still a major problem conforming the pharmaceutical industry. The most common method for improving the solubility is by increasing the surface area of the drug through micronization. But, in practice the effect of micronization is often disappointing, especially when the drugs are encapsulated or tablet. It is generally recognized that low s...

Eudragit S-100 coated sodium alginate microspheres of naproxen sodium: formulation, optimization and in vitro evaluation.

The aim of the study was to prepare site specific drug delivery of naproxen sodium using sodium alginate and Eudragit S-100 as a mucoadhesive and pH-sensitive polymer, respectively. Core microspheres of alginate were prepared by a modified emulsification method followed by cross-linking with CaCl2, which was further coated with the pH dependent polymer Eudragit S-100 (2.5 or 5 %) to prevent dru...
