The aim of the present study was to prepare and evaluate an osmotically controlled mucoadhesive cup-core (OCMC) containing aceclofenac. A special technique was used while preparing an OCMC. Stability of OCMC was determined in natural human saliva, and it was found that both pH and device are stable in human saliva. OCMC was evaluated by weight uniformity, thickness, hardness, friability, swelli...
Objective: The aim of the present study was to develop and evaluate the monolithic osmotic tablet (MOT) composed of the solid dispersion of ketoprofen (KETO), a poorly water-soluble drug. Solid dispersion technique is generally used for immediate release, as this maximizes the amount of drug absorbed. Sustained release may be obtained by combining solid dispersion technique with MOT so as to in...
INTRODUCTION Pulsatile Drug delivery systems are gaining a lot of interest as they deliver the drug at the right site of action at the right time and in the right amount, thus providing spatial and temporal delivery and increasing patient compliance. Pulsatile Drug Delivery systems are basically time-controlled drug delivery systems in which the system controls the lag time independent of envir...

Osmotically controlled oral drug delivery systems utilize osmotic pressure for controlled delivery of active agents[3]. These systems can be utilized for systemic as well as targeted delivery of drugs. The release of drugs from osmotic system is governed by various formulation factors such as the solubility and the osmotic pressure of the core components, nature of the rate controlling membrane...
Microporous osmotic tablet of diltiazem hydrochloride was developed for colon targeting. These prepared microporous osmotic pump tablet did not require laser drilling to deliver the drug to the specific site of action. The tablets were prepared by wet granulation method. The prepared tablets were coated with microporous semipermeable membrane and enteric polymer using conventional pan coating p...
terbutaline sulfate exhibits extensive first pass metabolism and a short elimination half life which makes frequent oral administration of the drug inevitable. a novel buccoadhesive controlled delivery system of the drug can easily overcome the problem. a two-layered core tablet composed of a fast release layer made of mannitol, lactose, peg and the drug attached to a sustained release layer co...
Controlled porosity osmotic tablet of carvedilol phosphate prepared and evaluated in this study. Carvedilol phosphate is very low soluble drug. So it is difficult to formulate osmotic tablet of carvedilol phosphate which gives drug release up to 24 hr at zero order. To get desired dissolution profile various formulation parameters like osmogen concentration, level of weight gain and level of po...
