There have been significant medical advances in recent years in the area of drug delivery systems. Using these systems allows the medicine to be delivered exactly to the target tissue or organ, and the rate of drug release will be controlled for a long time. The purpose of using drug delivery systems is to maintain long-term optimal drug concentration in the blood and thus increase the effectiveness and reduce the side effects of medication.
Simin Shibani, the project manager, explained “Azithromycin is an antibiotic used to treat many different types of infections caused by bacteria. Since this antibiotic has a high molecular weight and size, it can hardly pass through the outer membrane of bacteria. Thus, even in the case of using a drug delivery system, it has a low treatment efficiency.”
