  1. The proportion of a drug or other substance that enters the circulation when introduced into the body and so is able to have an active effect


  1. In pharmacology, bioavailability is used to describe the fraction of an administered dose of unchanged drug that reaches the systemic circulation, one of the principal pharmacokinetic properties of drugs. ...
  2. The amount of drug which reaches the site of physiological activity after administration
  3. (bioavailable) Able to be absorbed by a living organism
  4. (bioavailable) The ability of a drug or other substance to be absorbed and used by the body. Orally bioavailable means that a drug or other substance that is taken by mouth can be absorbed and used by the body.
  5. (BIOAVAILABLE) the unbound (free) fraction of a hormone that has left the bloodstream to enter target tissues in the body. This unbound fraction is present and measurable in saliva.
  6. (Bioavailable) Compounds that are bioavailable at a site like Kalamazoo River are those that are located in the river water or the top layer of sediment, where they are readily available to fish, plants, and other wildlife.
  7. (Bioavailable) In a chemical form that is suitable for uptake by organisms.*
  8. The ease with which something is absorbed from the digestive tract. The higher the bioavailability, the greater the total absorption and rate of absorption.
  9. the amount of a drug in a capsule or tablet that is actually metabolized.
  10. The rate and extent to which an active drug or metabolite enters the general circulation, thereby permitting access to the site of action.
  11. The fraction of a substance that can be absorbed by the body through the gastrointestinal system, the pulmonary system and the skin. By its definition, bioavailability also includes the process of bioaccessibility.
  12. A measure of how available a toxic pollutant is to the biological processes of an organism. The less the bioavailability of a toxic substance, the less its toxic effect on an organism.
  13. A term used to describe the way chemicals are absorbed by humans and other animals.
  14. availability to living organisms, based on chemical form
  15. The relative ability of nutrients in foods to be properly digested, and absorbed. For example, the iron in vegetable foods is less absorbable than the iron in meat foods. The bioavailability of iron in vegetables increases when vitamin C is also present, having been consumed during the same meal.
  16. Refers to the availability of a nutrient to the body. Nutrients that are bioavailable are absorbed by the organism, digested and distributed to the various parts of the body where they are required to support good health.
  17. refers to the speed and or the amount (percentage) of a nutrient that is absorbed and utilized.
  18. The amount of chemical that enters the general circulation of the body following administration or exposure.
  19. Bioavailability is the degree to which an agent, such as a drug or nutrient, becomes available at the site of activity in the body.
  20. Also referred to as availability, this is the amount of a drug that is absorbed into circulation after administration of a specific dosage.
  21. The efficiency with which any dietary nutrient is used in the body.
  22. The rate and extent of drug absorption. In other words, it is the fraction of the dose that will reach the site of measurement after extravascular administration, compared to a standard route. ...
  23. existence of a substance in a physical and chemical state which can be taken up by living organisms
  24. A measurement of the amount of a compound absorbed into the bloodstream.
  25. Bioavailability is the measurement of the rate and amount of a chemical compound that ultimately achieves systemic circulation and is absorbed with an active effect into various target tissues after it is eaten or administered.
