Formulation Design and In Vitro Evaluation of Carbamazepine Gastroretentive Floating Drug Delivery System for Oral Application
Abstract
The objective of the study was to develop a gastroretentive floating drug delivery system containing Carbamazepine as a model drug with two hydrophilic polymers i.e. Methocel K4M and Carbomer 971. The effect of these polymers was evaluated in terms of physical characteristics, floating behavior and drug release. Floating lag time was found to be 4-136 sec and total floating time was > 18 h depending on the formulations. Drug release was studied for 8 h. Simulated drug release pattern in different kinetic model suggests that the mechanism controlling of the drug release from all formulations was the anomalous or non-Fickian and Case II type release. Polymer with lower viscosity (HMPC K4M) was found to be beneficial than higher viscosity polymer (Carbopol 971) in improving the release properties of gastric floating drug delivery system. Incorporation of Carbopol also in formulation helped in maintaining buoyancy of system with desirable drug release. Further study is required in case of in vitro- in vivo correlation but the present study will help us to future scientists working in this area to effectively use the potential of this drug delivery system for the benefit of mankind.
