Bioenhancers – A Review

Bioenhancers are chemical entities which promote and augment the bioavailability of the drugs which are mixed with them and do not exhibit synergistic effect with the drug. The need for bioenhancers arises due to drugs which are poorly available, administered for long periods, toxic and expensive. Bioenhancers can be classified based on their natural origin as well as based on the various mechanisms elicited by them when used in combination with drugs to improve their bioavailability.
