Background: Carbamazepine is used in the management of seizures by decreasing the central nervous system disorganized electrical activity and also has analgesic properties. It exerts serious side effects in normal administration owing to the extrapyramidal effect which signifies the importance of its incorporation into the extended-release system to reduce the possible side-effects associated with the drug. Objective: In the present study, multiple extended-release systems of Carbamazepine was formulated using various polymers. The effect of viscosity modifying polymers of different grades and its contribution to the release behaviour was examined. Different formulations were prepared and studied for their drug release potentials. Among them, selected formulations were further evaluated for dimensions of the portal. Methodology: Trial batches were designed with osmogen and cellulose polymers along with solubility enhancer as the model drug used to have low solubility. The optimization of the formulation was done by wavering concentration of cellulose polymers and the dimensions of the release portal were determined. Result: A new strategy for extended delivery has been accomplished by extended-release solid oral tablet formed by the combination of solubility enhancers and cellulose polymers. The arrangement of a hydrophilic polymer with a surfactant as solubility promoter and the use of cellulose polymer represents an innovative and effective approach for the delivery of poorly water-soluble. The study further can be used to deliver a cost-effective and robust system for water-insoluble drugs in a zero-order manner. Conclusion: The rapid development of these investigational therapeutic formulations will put forward new avenues for future commercialization of drug after completion of required clinical studies.
