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 کاملIn vitro Release Kinetics Study of Diltiazem Hydrochloride from Wax and Kollidon SR Based Matrix Tablets
Extended-release matrix tablets of diltiazem hydrochloride (DTZ) were prepared using waxy materials alone or in combination with Kollidon SR. Matrix waxy materials were carnauba wax (CW), bees wax (BW), cetyl alcohol (CA) and glyceryl monostearate (GMS). Dissolution studies were carried out by using a six stations USP XXII type 1 apparatus. The in vitro drug release study was done in 1000 ml ph...

متن کاملA new model describing the swelling and drug release kinetics from hydroxypropyl methylcellulose tablets.
A novel mathematical model for the water transport into and drug release from hydroxypropyl methylcellulose (HPMC) tablets is presented. Fick's second law of diffusion is used to describe the mass transfer processes in the three-component system drug/polymer/water. Numerical solutions of the respective set of partial differential equations are provided, considering axial and radial diffusion wi...
متن کاملIn Situ Cross-Linking of Polyanionic Polymers to Sustain the Drug Release from Theophylline Tablets
The aim of this study was to develop an extended-release tablet formulation using a new in situ cross-linking method. The effects of polyvalent cations on theophylline release from tablets made with the polyanionic polymers sodium alginate and sodium carboxymethylcellulose, were investigated. Different miliequivalents of the di and tri-valent cation, Ca2+ and Al3+, were added to tablet form...
