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 Absorption Half-Life of Drug?
Absorption Half-Life of Drug calculator uses Absorption Half Life = ln(2)/Absorption Rate Constant to calculate the Absorption Half Life, The Absorption half-life of drug is defined as the time required for 50% of a given dose of drug to be absorbed into the systemic circulation. Absorption Half Life is denoted by ta/2 symbol.
How to calculate Absorption Half-Life of Drug using this online calculator? To use this online calculator for Absorption Half-Life of Drug, enter Absorption Rate Constant (ka) and hit the calculate button. Here is how the Absorption Half-Life of Drug calculation can be explained with given input values -> 3600.765 = ln(2)/0.0001925.
