A Box-Behnken design with three replicates was used for preparation and evaluation of Eudragit vancomycin (VCM) nanoparticles prepared by double emulsion. The purpose of this work was to optimize VCM nanoparticles to improve the physicochemical properties. Nanoparticles were formed by using W1/O/W2 double-emulsion solvent evaporation method using Eudragit RS as a retardant material. Full factor...

abstract: background: a new type of drug delivery system known as mucoadhesive film has been developed for oral thrush treatment. due to comfortable use of this drug delivery system, this would be encouragingly utilized, especially in babies and patient under chemotherapy. nystatin mucoadhesive film (nmf) is a polymeric film which is adhered to front upper gum and back to the upper lip and rele...

the aim of the present study was to develop exemestane loaded polymeric nanoparticles for improved oral bioavailability of exemestane. exemestane loaded nanoparticles were prepared by solvent displacement method with eudragit rl 100 and eudragit l 100 as polymers and pluronic® f-68 as surfactant. the influence of various formulation factors (drug: polymer ratio and concentration of surfactant) ...

The objective of the present study was to prepare controlled release formulation of Moxifloxacin hydrochloride ocular nanoparticles. The nanoparticles were prepared by solvent displacement method using Eudragit RL 100 as a polymer. Different formulations were prepared by varying the ratios of drug and polymer and varying the ratios of organic and aqueous phase. The formulations were evaluated i...

Topical propranolol has been used in clinics for treating cutaneous infantile haemangiomas, but frequent applications of semi-solid preparations are required to maintain therapeutic drug concentrations the skin layers over time. This work aims study preparation patches by hot-melt ram extrusion printing, a novel technique suitable personalization dosage forms. The steps are: i) mixing poly-ammo...

A commercial protease, Esperase, was covalently linked to Eudragit S-100, a reversible soluble–insoluble polymer by carbodiimide coupling. When compared to the native enzyme, the immobilized form presented a lower specific activity towards high molecular weight substrates but a higher thermal stability at all temperatures tested. The optimum pH of the immobilized protease was shifted towards th...

An oral controlled release suspension of chlorpheniramine maleate was prepared using ion-exchange resin technology. A strong cation exchange resin Indion 244 was utilized for the sorption of the drug and the drug resinates was evaluated for various physical and chemical parameters. The drug-resinate complex was microencapsulated with a polymer Eudragit RS 100 to further retard the release chara...
