Abstract: The systemic delivery of pharmacological substances generally exhibits several significant
limitations associated with the bio-distribution of active drugs in the body. Human body’s defense mechanisms
have been found to become impediments to drug delivery. Various technologies have evolved to
overcome these limitations, including computational approaches and advanced drug delivery. As the body
of a human has evolved to defend itself from hostile biological as well as chemical invaders, the biological
barriers, such as ocular barriers, blood-brain barriers, intestinal and skin barriers, also limit the passage
of drugs across desired sites. Therefore, efficient delivery remains an utmost challenge for researchers
and scientists. The present review focuses on the techniques to deliver the drugs with efficient therapeutic
efficacy at the targeted sites. This review article provides an insight into the main biological barriers
along with the application of computational or numerical methods to deal with different barriers by
determining the drug flow, temperature and various other parameters. It also summarizes the advanced
implantable drug delivery systems to circumvent the inherent resistance exhibited by these biological
barriers, and in turn, to improve the drug delivery process.
