A Review of the Efficacy of Nanodrug Delivery Systems: Is It Worth the Hype? Daisy P Pugazhenthi Ramya A Dheenadhayalan Murugavel Karthickeyan Krishnan Shanmugasundaram Palani

Nanodrug delivery systems are gradually becoming the current “talk of the town” due to their efficiency in treating different diseases in a more advanced manner when compared to conventional drug-delivery systems. It is well known that drugs can be given through various routes of administration, such as the popular oral, subcutaneous, and intravenous routes. It is quite surprising that formulating these same drugs as nanoparticles (NPs) and administering them to the patient could produce better results. Different studies have shown the effects of nanodrug delivery systems in targeting cancer cells, ameliorating pulmonary arterial hypertension, and providing improved treatments for ophthalmic conditions such as glaucoma. In most studies, nanodrug delivery systems have been shown to exhibit targeted action at the desired site or organ, low toxicity, and fewer systemic side effects. These new insights can provide an enhanced understanding of the benefits of NP formulations of drugs, as well as open up new pathways for future creative techniques in addressing emerging medical conditions. Furthermore, these formulations generally consist of polymer- or liposome based or coated NPs, as they are easily biodegradable, meaning they have a higher ability to disintegrate and, at the same time, are not harmful to living tissues, thereby displaying greater compatibility. New connections can be established through the utilization of NPs in the treatment of emerging diseases worldwide. Data from these studies could provide a foundation for groundbreaking and innovative strategies in coping with or fighting even the recent COVID-19 pandemic.
