Facile Synthesis of Chitosan Capped Mesoporous Silica Nanoparticles: A pH Responsive Smart Delivery Platform for Raloxifene Hydrochloride.

An encapsulation of model drug raloxifene hydrochloride (RAL) inside the chitosan decorated pH responsive mesoporous system has a greater potential for accumulating in the tumor cells. The present study involves synthesis of surface modified mesoporous silica nanoparticles (MSN) with the aim of achieving pH sensitive drug delivery system. A silanol skeleton of MSN has been productively modified to amine intermediate which served as a firm platform to adapt chitosan grafted assembly and systematically evaluated.

Study on formulation variables of methotrexate loaded mesoporous MCM-41 nanoparticles for dissolution enhancement.

The aim of this study was to develop methotrexate loaded mesoporous MCM-41 nanoparticles for improved dissolution of methotrexate. The mesoporous MCM-41 nanoparticles act as carrier for drug and increase the solubility of the drug. In order to achieve this objective small pore size MCM-41 nanoparticles have been synthesized followed by drug loading process.

Nimodipine loaded PLGA nanoparticles: formulation optimization using factorial design, characterization and in vitro evaluation.

The present study was aimed at developing a sustained release formulation of Nimodipine (NIM) nanoparticles using the biodegradable polymers, poly (lactide-co-glycolide) (PLGA 50:50 and 85:15) as carrier. NIM is a widely used calcium channel blocker which has to be administered as an intravenous infusion for a prolonged period of 1-2 weeks in the treatment of cerebral vasospasm. A sustained release biodegradable formulation would serve to replace this conventional therapy of continuous intravenous administration.

Albumin microspheres as carriers for the antiarthritic drug celecoxib.

The present study investigates the preparation of celecoxib-loaded albumin microspheres and the biodistribution of technetium-99m ((99m)Tc)-labeled celecoxib as well as its microspheres after intravenous administration. Microspheres were prepared using a natural polymer BSA using emulsification chemical cross-linking method. The prepared microspheres were characterized for entrapment efficiency, particle size, and in vitro drug release.
