The objective of this study was to develop a novel bacterially-triggered micro-particular system of de-esterified tragacanth (DET) in combination with Eudragit S-100 coated capsules for colon drug delivery of 5-fluorouracil (5-FU) using microemulsion method. The loading study was conducted at different drug-to-polymer ratios and cross-linker concentrations. The maximum loading efficiency was ac...

Background Colon-targeted oral nanoparticles (NPs) have emerged as an ideal, safe, and effective therapy for ulcerative colitis (UC) owing to their ability to selectively accumulate in inflamed colonic mucosa. Cyclosporine A (CSA), an immunosuppressive agent, has long been used as rescue therapy in severe steroid-refractory UC. In this study, we developed CSA-loaded dual-functional polymeric NP...

Objective: To formulate economic transdermal patch of lornoxicam (LX) and to study its anti-inflammatory activity on acute and chronic inflammatory in rat models Method: Three LX transdermal patches (F1, F2 and F3) consist of Eudragit RL-100 and RS-100 in three different ratios (1:2, 1:1 and 2:1) were prepared respectively by the solvent evaporation technique. All formulations contain diethylph...

OBJECTIVES A Box-Behnken design was used for evaluation of Eudragit coated diclofenac pellets. The purpose of this work was to optimize diclofenac pellets to improve the physicochemical properties using experimental design. MATERIALS AND METHODS Diclofenac was loaded onto the non-pareil beads using conventional coating pan. Film coating of pellets was done at the same pan. The effect of plast...

Drug controlled release technologies (DCRTs) represent an opportunity for designing new therapies. Main objectives are dose number optimization and secondary effects reduction to improve the level of patient/client acceptance. The present work studies DCRTs based in blended polymeric implants single long-term therapies florfenicol (FF), a broad spectrum antibiotic. Polymers used were PLGA Eudra...

The influence of various polymers on the release rate of lithium carbonate from matrix-type tablets was investigated in an attempt to formulate a sustained release solid dosage form. For this purpose, tablets containing 450 mg of lithium carbonate along with various amounts of Carbopol 934P, 971P, 974P, Pemulen and Eudragit RLPO as retarding agents and inactive ingredients (e.g. PVP, Avicel or ...

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) ...
