Abstract: As a serious neurodegenerative disorder, the prevalence of Parkinson's disease is predicted to dramatically increase in the coming decades. Despite the development of numerous drugs for its treatment, oral administration of levodopa has remained the simplest and most effective pharmacological approach in the management of Parkinson's disease. In this research, the levodopa-imprinted hydrogel was synthesized by reverse emulsion polymerization in the presence of levodopa followed by modification with polypyrrole. The antioxidant activity of amphiphilic non-levodopa-imprinted hydrogel was studied by 2,2-Diphenyl-1-picrylhydrazyl active radicals, which indicated 100% efficiency in the applied amount. Amphiphilic non-levodopa-imprinted hydrogel cytotoxicity was evaluated by MTT assay, which confirmed no significant toxicity after 24 and 48 h even at high concentrations. Moreover, in vitro releasing property of the levodopa-imprinted hydrogel was studied in the pH range of 4 to 7.4, which reached 60 and 80% within 160 h, respectively
