l-Dopa@MSNs based on the concept of drug-structure-directing agents were successfully prepared and proved to be programmed oral l-Dopa release nanosystem pH responsive for treatment Parkinson's disease.

Over the years, polymeric delivery systems have been devoted to overcoming disastrous consequences of using specific medications [1,2]. Among all, stimuli-responsive drug emerged as promising tools for targeting and controlling release therapeutic agents [3-5].

triptoreline is a potent agonist of luteinizing hormone-releasing hormone, currently used in the treatment of prostatic cancer where therapy may be required over months or years. frequent injection of drug decreases patients’ compliance. the present study describes the formulation of a sustained release microparticulate drug delivery system containing triptoreline acetate, using poly (d,l lacti...
