Efficacy of Novel Drug Delivery Systems for Insulin Administration and Technological Advances in Diabetes Mellitus: Review.

Diabetes mellitus (DM) is a clinical syndrome characterized by disturbance in carbohydrate, fat and protein metabolism due to either insulin deficiency or insulin resistance. Oral medications and insulin injections have typically been the conventional delivery modalities of diabetes treatment for both type 1 and patients with advanced type 2 diabetes. In spite of this, these treatments have some drawbacks, including low efficacy, unwanted side effects and the possibility of hypoglycemia. New developments in medication delivery techniques, such as insulin pumps, inhalers and patches, have been made with the intention of enhancing the efficacy of the treatment. Insulin pumps allow for precise and flexible administration of insulin, which, in turn, reduces the number of episodes of low blood sugar. The use of inhalers provides a non-invasive alternative that facilitates rapid glycemic management and increases patient satisfaction. Currently in the process of being developed, insulin patches provide a means of administering insulin that is both simple and painless. In this review, we investigate the efficacy, safety and practicability of various technological breakthroughs, such as insulin pumps, smart insulin pens and continuous glucose monitoring systems. In addition to this, it addresses the challenges that are preventing a wider acceptance, such as the costs, the availability and the requirements for training. In order to enhance patient outcomes and usher in a new era of diabetes care that is increasingly driven by technology, the report places a strong emphasis on the necessity of continued research and innovation.
