In pharmacology, bioavailability (BA or F) is a subcategory of absorption and is the fraction of an administered dose of unchanged drug that reaches the systemic circulation, one of the principal pharmacokinetic properties of drugs.Click to see full answer. In respect to this, how do you determine bioavailability of a drug?Bioavailability is usually assessed by determining the area under the plasma concentration–time curve (AUC—see Representative plasma concentration–time relationship after a single oral dose of a hypothetical drug). The most reliable measure of a drug’s bioavailability is AUC.Also Know, what factors affect bioavailability of a drug? Factors Affecting Bioavailability Absorption. Food Effect. Drug metabolism/ biotransformation. Energy dependent efflux transporters. Physico-chemical factors. First pass metabolism. CYP450 isozymes. Besides, why is the bioavailability of a drug important? A substance will only take effect if it can be absorbed by the body, so bioavailability is the key to creating a supplement that delivers proven benefits. In pharmacology, for example, it refers to how quickly a drug enters the circulatory system and reaches the desired area, so that it can take effect.What is the difference between absorption and bioavailability?It is suggested that absorption be defined as movement of drug across the outer mucosal membranes of the GI tract, while bioavailability be defined as availability of drug to the general circulation or site of pharmacological actions.
