DESIGN AND INVITRO CHARACTERIZATION OF METFORMIN LOADED RESEALED ERYTHROCYTES

Abstract

 Objective: Metformin is an oral antidiabetic drug in the biguanide class. It is the first-line drug of choice for the treatment of type 2 diabetes. The objective of the present study was to retard the release of metformin using carrier erythrocyte for getting a parenteral slow release depot formulation.Methods: The study retards the release of metformin by encapsulating in carier erythrocyte. Endocytosis is the method used for the encapsulation of the drug metormin.Results: The optimized formulation shows 98.34% of drug release within 12 days. From the invitro release data zero order kinetic graph shows the best fit graph.  % cell recovered was found to be 73-78% and it suggests that the loading technique was less destructive.Conclusion: The optimized formulation is a perfect carrier for the parenteral slow release depot of metformin.Keywords: Resealed erythrocytes, cross linking, cell recovery, endocytosis, slow release depot formulation
