Objective: The current study was based on the many different dose frequencies of entacapone, an anti-Parkinson's drug that was loaded with microsponges to change the dose frequency of the drug administration. Methods: Microsponges were made utilizing polymethacrylate polymers such as eudragit L100, eudragit S 100, and eudragit RS 100 in various ratios using a quasi-emulsion solvent diffusion, ratios such as (1:0.5, 1:1, 1:1.5 and 1:2). These polymers release the drug in a controlled manner. The polymer used for the preparation of microsponges was useful in forming sponges in which the drug was entrapped. By using the 3 polymers,12 formulations were prepared. Results: FT-IR and DSC tests were carried out and it was clear from the FT-IR and DSC spectra that there were no interactions between the entacapone and the polymer. out of 12 formulations 3 formulations were selected as optimized formulations based on the production yield (%), encapsulating efficiency, drug loading (%), and SEM analysis says that the produced microsponges formulation was extremely porous, indicating their potential for increased drug loading.
