Bioavailability – Challenges and Advances in Drug Targeting

It has been a very challenging task in drug development to handle bioavailability of drug molecules during targeting. Foremost challenges include the time span involved apart from various complexities, wrong methods or failure in outcome, increasing manual and financial requirements to be managed in the drug discovery process. Among this bioavailability is one of the biggest challenges handled to successfully identify druggability in a molecule. Various methods of administration and targeting has been used including co-crystallization, micro emulsion, micellar solubilization and other traditionally which has also expanded to other methods as morphous solid dispersion, liposomes, and complexions. To enable precision in availability of drug molecule at the targeted site. There has been an increase in bioavailability of potential drugs. This review comprehensively determines challenges and methods used in drug targeting based on their bioavailability.
