Influence of Organic Acids on Diltiazem HCl Release Kinetics from Hydroxypropyl Methyl Cellulose Matrix Tablets
The matrix tablets of diltiazem hydrochloride were prepared by direct compression using hydroxypropyl methyl cellulose (HPMC) and various amounts (2.5%, 5.0%, 10% and 20%) of citric acid, malic acid and succinic acid. The characterization of physical mixture of drug and organic acids was performed by Infra-red spectroscopy. An organic acid was incorporated to set up a system bringing about grad...
متن کاملDesign and Evaluation of Ethyl Cellulose Based Matrix Tablets of Ibuprofen with pH Modulated Release Kinetics
Controlled release preparations have been reported to reduce the gastro irritant and ulcerogenic effects of non steroidal antiinflammatory drugs. In the present study, an attempt was made to develop matrix tablet-based controlled release formulations of ibuprofen, using ethyl cellulose as the rate-controlling polymer. In order to prevent initial release of the drug in the acidic environment of ...

Introduction: Acne is a disorder of the pilosebaceous unit of the skin and can present as non inflammatory and or inflammatory lesions. Tretinoin has been used therapeutically for over three decades. It is best known for its comedolytic effects on acne. It also inhibits comedone rupture, thus decreasing inflammatory events. Tretinoin is available in 0.01% to 0.1% as cream, gel or lotion. The ...
متن کاملEvaluation of drug release kinetics from ibuprofen matrix tablets using HPMC.
The aim of this study is to develop a once-daily sustained release matrix tablet of ibuprofen using hydroxypropyl methylcellulose (HPMC) as release controlling factor and to evaluate drug release parameters as per various release kinetic models. In order to achieve required sustained release profile tablets were directly compressed using Avicel pH 101 and Magnesium stearate. The formulated tabl...
متن کاملDesign and Evaluation of Hydroxypropyl Methylcellulose Matrix Tablets for Oral Controlled Release: A Historical Perspective
Hydrophilic matrix tablets (matrices) for oral use are designed to hydrate on swallowing, and form a ‘gel’ layer of hydrated polymer at the tablet surface to control the rate of drug release during passage of the matrix through the gastrointestinal tract. During gastrointestinal transit, the matrices are reduced in size through surface erosion and dissolution. This reduces the probability of ex...
