Abstract
Insulin has played an important role in the treatment of diabetes since its discovery in the early 1920s. Initially derived from animal sources, insulin production underwent significant changes with the advent of recombinant DNA technology, allowing for the development of insulin analogs and biosimilar products. Through scientific and technological advances, various types of insulin have been engineered to cater to diverse patient populations, improving the quality, safety, efficacy, and accessibility of these products. There are currently over 50 insulin products approved by the U.S. Food and Drug Administration (FDA), each tailored to meet specific therapeutic needs. This review traces the journey of insulin, from its discovery and purification to recombinant DNA technology, biosimilar developments, and recent advancements in formulation including ultra-rapid formulations and combination therapies. The review also examines the impact of structural and formulation modifications on the pharmacokinetics and pharmacodynamics of insulin, resulting in a range of insulin products with different time-action profiles (rapid-, short-, intermediate-, and long-acting insulins). These technological and manufacturing developments have improved the quality of insulin products available to the public and have made insulin therapy safer, more effective, and more adaptable to individual patient needs, greatly enhancing the management of diabetes over time and patient quality of life.
