Abstract

In medicine, bioavailability is the percentage of a drug that enters the bloodstream and can be used to treat a patient. It has proven challenging throughout time to develop techniques that allow oral administration of most drugs, regardless of their properties, to achieve therapeutic systemic availability. This will be an impressive feat, considering that over 90% of pharmaceuticals are known to have limitations on their oral bioavailability. Improving bioavailability is crucial for optimizing the efficacy and safety of drugs. This review covers a wide range of techniques, including physical, chemical, and formulation approaches, highlighting their mechanisms, advantages, and limitations. Inhibitions of efflux pumps, inhibition of presystemic metabolism, and innovative drug delivery systems that capitalize on the gastrointestinal regionality of medicines are some of the new techniques that have drawn increased interest. Nanotechnology in pharmaceuticals is also being used in this field. We have collected the literature data from 2009 to 2024 using Science Direct, PubMed/Medline, Scopus, and Google Scholar.
