Pefloxacin mesylate is a flouroquinolone antibacterial drug effective in the treatment of bacterial conjunctivitis. The objective of the present work was to develop ocular inserts of pefloxacin mesylate and evaluate their potential for sustained ocular delivery. Reservoir-type ocular inserts were prepared by the film casting technique in teflon coated Petri dishes and characterized in vitro by ...

Emulsion-solvent evaporation technique was used to prepare Diclofenac sodium (DS) loaded Kollidon® SR (KSR) microspheres. Cellulosic polymers (HPMC 6 cps, 15 cps) and polymethacrylic polymers (Eudragit E100, Eudragit RL PO, and Eudragit RS PO) were added with KSR at 10% wt/wt of KSR. The effect of these polymers on drug content, particle size, surface morphology and DS release rate was evaluate...

The objective of the present investigation was to prepare and evaluate ocular inserts of moxifloxacin. An ocular insert was made from an aqueous dispersion of moxifloxacin, sodium alginate, polyvinyl alcohol, and dibutyl phthalate by the film casting method. The ocular insert (5.5 mm diameter) was cross-linked by CaCl2 and was coated with Eudragit S-100, RL-100, RS-100, E-100 or L-100. The in v...

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...

rug delivery to the colon is beneficial not only for the oral delivery of proteins and peptide drugs (degraded by digestive enzymes of stomach and small intestine) but also for the delivery of low molecular weight compounds used to treat diseases associated with the colon or large intestine such as ulcerative colitis, diarrhea, and colon cancer. In addition, the colon has a long retention time ...

Oral mucosal lesions are related to several etiologies, including trauma, infection, and immunologic and neoplastic diseases. Their prevalence varies greatly depending on ethnicity, gender, and exposure to risk factors. Currently, most oral mucosal lesions are treated with creams, mouthwashes, or gels containing suitable drugs. However, topical medications may be relatively ineffective as they ...
