Ethylcellulose is a biocompatible polymer attracting increasing interest for biomedical applications. In the present work, formation of folate-ethylcellulose nanoparticle complexes from nano-emulsion templates prepared by low-energy approach, using aqueous components suitable applications has been investigated. The composition component shown to be crucial stable nano-emulsions and influences z...

Objective: The present study involved the preparation of Diclofenac sodium extended release hydrophobic matrix tablets formulated from Ethylcellulose polymer following its different grades, Ethocel Standard Premium and Ethocel Standard FP Premium. Methods: The matrix tablets were prepared with wet granulation method. Lubricated blends were characterized for physical properties like loose bulk d...

Microspheres are one of the novel drug delivery system and are formulated conveniently to obtain prolonged or controlled drug delivery to enhance the bioavailability and target drug to the specific sites. Ritonavir loaded ethylcellulose buoyant microspheres were formulated using ethylcellulose as rate retarding material. Buoyant microspheres were formulated by emulsion solvent diffusion method....

An emulsion solvent evaporation method was employed to prepare microspheres of ropinirole hydrochloride, a highly water soluble drug, by using ethylcellulose and PEG with the help of 32 full factorial design. The microspheres were made by incorporating the drug in a polar organic solvent, which was emulsified using liquid paraffin as an external oil phase. Effects of various process parameters ...

Small deformation rheology was used at a controlled strain of 0.05% and frequency from 1 to 100 Hz to obtain G0, G00, and tan(d) values for ethylcellulose oleogels of various compositions. Significant increases in both G0 and G00 were noted in oleogels prepared with 100 cP ethylcellulose as compared to 45 cP, yet no significant differences in tan(d) were observed among gels containing the same ...

Objective. The purpose of the recent study was to prepare and estimate sustained release of Ethylcellulose (300 cps) and Eudragit (RS 100 and RL 100) microparticles containing Propranolol hydrochloride used as a treatment of cardiovascular system, especially hypertension. Method. Propranolol hydrochloride was microencapsulated with different polymers (Ethylcellulose, Eudragit RS, and Eudragit R...

Recently, ethylcellulose/guar gum blends have been reported to provide ethanol-resistant drug release kinetics from coated dosage forms. This is because the ethanol insoluble guar gum effectively avoids undesired ethylcellulose dissolution in ethanol-rich bulk fluids. However, so far the importance of crucial formulation parameters, including the minimum amount of guar gum to be incorporated an...

The application rates for conventional herbicide formulations are generally greater than the recommended dosage, in order to overcome losses from degradation, leaching, volatilization, and sorption during the time needed for weed control. All these factors have encouraged the development of controlled release formulations (CRFs), which can reduce herbicides levels in the environment since less ...
