Bioavailability
The ability of a drug or other chemical to be taken up by the body and made available in the where it is needed.
About Bioavailability
The interactions between drug and body molecules are really just a series of chemical reactions. Understanding the chemical encounters between drugs and biological environments, such as the bloodstream and the oily surfaces of , is necessary to predict how much of a drug will be taken in by the body.
This concept, broadly termed bioavailability, is a critical feature that chemists and pharmaceutical scientists keep in mind when designing and packaging medicines.
No matter how well a drug works in a laboratory simulation, the drug is not useful if it can’t make it to its site of action.
