What is Pharmacokinetics?
Pharmacokinetics is a branch of pharmacology dedicated to determine the fate of substances administered to a living organism. The substances of interest include any chemical xenobiotic such as: pharmaceutical drugs, pesticides, food additives, cosmetics, etc. It attempts to analyze chemical metabolism and to discover the fate of a chemical from the moment that it is administered up to the point at which it is completely eliminated from the body. Pharmacokinetics is the study of how an organism affects a drug, whereas pharmacodynamics (PD) is the study of how the drug affects the organism. Both together influence dosing, benefit, and adverse effects, as seen in PK/PD models.
How to Calculate Relative Bioavailability of Drug?
Relative Bioavailability of Drug calculator uses Relative Bioavailability = (Area under curve Dosage A/Area under curve Dosage B)*(Dose Type B/Dose Type A) to calculate the Relative Bioavailability, The Relative bioavailability of drug formula is defined as the comparison of the bioavailability between two different dosage forms. Relative Bioavailability is denoted by Frel symbol.
How to calculate Relative Bioavailability of Drug using this online calculator? To use this online calculator for Relative Bioavailability of Drug, enter Area under curve Dosage A (AUCdosageA), Area under curve Dosage B (AUCdosageB), Dose Type B (DB) & Dose Type A (DA) and hit the calculate button. Here is how the Relative Bioavailability of Drug calculation can be explained with given input values -> 0.859273 = (1141/1732)*(15/11.5).
