Aim: The aim of this work is development and evaluation of chlorhexidine medicated chewing gums by different methods and to study the influence of different plasticizers and methods on physicochemical parameters and in vitro drug release profile. Materials and Methods: Chlorhexidine is an antibacterial agent used for management of tooth decay. The formulations are prepared with varying concentrations of plasticizers and synthetic gum base by different methods such as direct compression and...

Aims Food intake is known to have various effects on gastrointestinal luminal conditions in terms of transit times, hydrodynamic forces and/or luminal fluid composition and can therefore affect the dissolution behavior of solid oral dosage forms. The aim of this study was to investigate and detect the dosage form-dependent food effect that has been observed for two extended-release formulations of nifedipine using in vitro dissolution tests. Methods Two monolithic extended release formulations,...

This study explored the effect of nano-crystalline cellulose (NCC) on Meloxicam (MX) solid dispersion (SD) prepared by co-grinding technique compared to micro-crystalline cellulose (MCC) in presence of lactose. MX-tablets were prepared by direct compression of different co-ground SDs or physical mixtures. The solubility, dissolution, SEM and DSC of different preparations were studied. Flow-through cell apparatus (FTC) was used to study the dissolution of MX from tablets at pH 7.4. Generally,...
