Diclofenac sodium as ophthalmic dosage form is used for the treatment of the pain, swelling and redness of patients' eyes recovering from cataract surgery; however, it faces the bioavailability limitation of eye drops due to effective protective mechanisms and corneal barrier functions in the eyes. Therefore, this investigation was aimed to develop ocular film formulations to achieve controlled...
Doxazosin mesylate (DXM) sustained release pellets were prepared by an extrusion-spheronization and fluid-bed coating technique. The core pellets containing DXM were prepared by extrusion-spheronization technique, and coated by a fluid-bed coater to control the release of DXM. The factors affecting to properties of pellets, such as diluent content, type and coating level of coating agents and p...
Objective Eudragits are widely used polymers in the production of oral sustained release dosage forms. The application of these polymers in the production of inert insoluble matrices has been investigated. However the effect of particle size, compaction force and presence of Aerosil 200 as a glidant on the properties of Eudragit RS and RL matrices prepared by direct compression of their physic...
The aspire of this attempt was to design and evaluate aceclofenac loaded sustained release microspheres by emulsion solvent evaporation method, using different polymers like Ethyl cellulose (EC), Kollidon SR (KSR), Eudragit RS 100, Eudragit RL 100 and Hydroxypropylmethyl Cellulose (HPMC K100M). Microspheres were prepared using different stirring rate (1200, 1500, 2000rpm) and larger microsphere...
The aim of the present investigation was to prepare and evaluate novel bioadhesive vaginal tablets containing clotrimazole loaded microspheres in order to provide long-term therapeutic activity at the site of infection. Tablets were prepared by incorporating drug loaded microspheres and using bioadhesive polymers hydroxypropylmethylcellulose, sodium carboxymethylcellulose and Carbopol. Microsph...

The possibility of preparation of ophthalmic drug delivery systems using compressed anti-solvent technology was evaluated. Eudragit RS 100 and RL 100 were used as drug carriers, acetazolamide was the model drug processed. Compressed anti-solvent experiments were carried out as a semi-continuous or a batch operation from a liquid solution of polymer(s)+solute dissolved in acetone. Both technique...

A sustained-release tablet formulation should ideally have a proper release profile insensitive to moderate changes in tablet hardness that is usually encountered in manufacturing. In this study, matrix aspirin (acetylsalicylic acid) tablets with ethylcellulose (EC), Eudragit RS100 (RS), and Eudragit S100 (S) were prepared by direct compression. The release behaviors were then studied in two co...
