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 Elimination Half Life of Drug?
Elimination Half Life of Drug calculator uses Elimination Half Life = ln(2)/Elimination Rate Constant to calculate the Elimination Half Life, The Elimination half life of drug formula is defined as the inverse relationship with the rate at which a drug is removed from the body. Elimination Half Life is denoted by t_{b/2} symbol.
How to calculate Elimination Half Life of Drug using this online calculator? To use this online calculator for Elimination Half Life of Drug, enter Elimination Rate Constant (k_{e}) and hit the calculate button. Here is how the Elimination Half Life of Drug calculation can be explained with given input values -> 11.95081 = ln(2)/1.61111111111111E-05.
