Colon Specific Drug Delivery: Effect of Eudragit Enteric Coating on Hydroxypropyl Methylcellulose Matrix Tablets of Flurbiprofen
Objective: The present research is focused on developing flurbiprofen colon-specific tablets based on timed release and pH-sensitivity. Methods and Material: This study is designed to study the effect of eudragit coating on the drug release from hydroxypropyl methylcellulose matrix to achieve the colon-specific release. Hydroxypropyl methylcellulose matrix tablets were prepared by wet granulati...
متن کاملApplication of eudragit RS to thermo-sensitive drug delivery systems. I. Thermo-sensitive drug release from acetaminophen matrix tablets consisting of eudragit RS/PEG 400 blend polymers.
In order to develop the polymer materials having temperature-sensitive and high biological safety, Eudragit RS-PO and polyethylene glycol 400 (PEG 400) blend polymers (EPG) were prepared. The EPGs that have the glass transition temperature (Tg) at around the body temperature were prepared by the addition of 5--13% PEG 400 to Eudragit RS. As glassy polymers are not in thermodynamic equilibrium b...
متن کاملRole of Eudragit in Targeted Drug Delivery
An ideal drug delivery system will possess three main properties: (a) It will be a single dose for the whole duration of treatment. (b) It will deliver the active drug directly at the site of action. (c) It will possess possible fewer side effects. Above approaches are achieved with the help of suitable choice of polymer. When it comes to targeted drug release profiles, Eudragit is the pharmace...
متن کاملDrug Transport Mechanisms from Carbopol/Eudragit Verapamil Sustained-Release Tablets
The objectives of this study were to compare dissolution profiles of a verapamil (VRP) formulation manufactured inhouse and Isoptin SR using USP Apparatus 2 and 3 and to elucidate drug release kinetics of these dosage forms. Eudragit NE 30D (ethyl acrylate–methyl methacrylate copolymer in a 2:1 ratio) aqueous dispersion was used as a granulating binder for the manufacture of VRP mini-matrix sus...
متن کاملMatrix Tablets: An Effective Way for Oral Controlled Release Drug Delivery
The purpose of this review article is to characterize all of the parameters regarding the types, polymers used, and release kinetics of matrix tablets. Matrix system was the earliest oral extended release platform for medicinal use. Matrix tablets are most commonly used methods to modulate the release profile of drugs. They are much desirable and preferred for such therapy because they o...
