| Aerospace | Bioavailability is the degree to which an agent, such as a drug or nutrient, becomes available at the site of activity in the body. (references) | ||
| Energy | Degree to which chemicals can be taken up by organisms. (references) | ||
| Health | 1: Rate and extent to which a drug is absorbed or is otherwise available to the treatment site in the body. (references) | 2: The degree to which a drug or other substance becomes available to the target tissue after administration. (references) | |
| Medicine | 1: The proportion of the active drug in a formulation that is absorbed and therefore available to exert its pharmacological effect. Source: European Union.

(references) | 3: Refers to that proportion of a drug which reaches the systemic circulation unchanged after a particular route of administration When drugs are taken by mouth their bioavailability is determined by factors in the drug-which include the nature of the molecule, its stability, and the formulation administered-and in the patient-such as a reduced intestinal surface area as a result of celiac disease or intestinal resection and whether or not the drug is taken with a meal.

| Wikipedic | In pharmacology, bioavailability is used to describe the fraction of an administered dose of medication that reaches the systemic circulation, one of the principal pharmacokinetic properties of drugs. By definition, when a medication is administered intravenously, its bioavailability is 100%. However, when a medication is administered via other routes (such as by mouth), its bioavailability decreases (due to incomplete absorption and first-pass metabolism). Bioavailability is one of the essential tools in pharmacokinetics, as bioavailability must be considered when calculating dosages for non-intravenous routes of administration. (references) | ||
