  • Discovery of a new chemical entity that exerts pharmacological effects for curing or treating diseases or relieving symptoms is only the first step in the drug developmental process. In the developmental cycle of a new drug, the delivery of a desired amount of a therapeutic agent to the target at a specific time or duration is as important as its discovery. In order to realize the optimal therapeutic outcomes, a delivery system should be designed to achieve the optimal drug concentration at a predetermined rate and at the desired location....

  • Despite the advances in the development of new drugs, a drug may never reach the target organ, or it may be difficult to achieve the necessary level of drug in the body. Large doses can result in serious side effects, and can harm normal cells and organs as well as diseased cells. Hence controlled release and the targeting of delivery systems must evolve in parallel to drug research.

  • Ovarian cancer is the leading cause of death among women with gynecologic malignancies in the United States. Advanced ovarian cancers are difficult to cure with the current available chemotherapy, which has many associated systemic side effects. Doxorubicin is one such chemotherapeutic agent that can cause cardiotoxicity. Novel methods of delivering chemotherapy without significant side effects are therefore of critical need.
