Preparation and Characterization of Nitrendipine- loaded Eudragit RL 100 Microspheres Prepared by an Emulsion-Solvent Evaporation Method
Purpose: The aim of the work was to prepare nitrendipne-loaded Eudragit RL 100 microspheres to achieve sustained release nitrendipine. Method: Nitrendipne-loaded Eudragit RL 100 microspheres were prepared by an emulsion-solvent evaporation method using ethanol/liquid paraffin system. The resultant microspheres were evaluated for average particle size, drug loading, in vitro drug release and rel...
متن کاملIn vitro Evaluation of Novel Sustained Release Microspheres of Glipizide Prepared by the Emulsion Solvent Diffusion-Evaporation Method
The objective of the current investigation is to reduce dosing frequency and improve patient compliance by designing and systematically evaluating sustained release microspheres of Glipizide. An anti-diabetic drug, Glipizide, is delivered through the microparticulate system using ethyl cellulose as the controlled release polymer. Microspheres were developed by the emulsion solvent diffusion-eva...
متن کاملPhysicochemical Characterization of a Hydrophilic Model Drug-Loaded PHBV Microparticles Obtained by the Double Emulsion/Solvent Evaporation Technique
Micropartículas de poli(3-hidroxibutirato-co-3-hidroxivalerato) (PHBV) contendo um fármaco modelo hidrofílico, o cloridrato de metformina (MH), foram obtidas pela técnica de emulsão múltipla/evaporação do solvente. Diversas formulações foram preparadas, com o objetivo de investigar a influência de cada composição sobre a eficiência de encapsulação (EE). O resultado mais elevado de EE (9,76%) fo...
متن کاملDroplet-based microfluidics for emulsion and solvent evaporation synthesis of monodisperse mesoporous silica microspheres.
A novel method for the fabrication of monodisperse mesoporous silica particles is suggested. It is based on the formation of well-defined equally sized emulsion droplets using a microfluidic approach. The droplets contain the silica precursor/surfactant solution and are suspended in hexadecane as the continuous oil phase. The solvent is then expelled from the droplets, leading to concentration ...
متن کاملFormulation and Evaluation of Sustained Release Microspheres of Acetazolamide by Solvent Evaporation Technique
ISSN:0975-1459 Sustained release microcapsules of acetazolamide, a short half life carbonic anhydrase inhibitor, was developed to reduce the frequency of drug administration, ease of dose adjustment and improve patient compliance. In this study, sustained release microcapsules of acetazolamide was prepared by solvent evaporation techniques using Eudragit RL/RS as polymer and particle size, enca...
