## Elimination Half Life of Drug Solution

STEP 0: Pre-Calculation Summary
Formula Used
Elimination Half Life = ln(2)/Elimination Rate Constant
tb/2 = ln(2)/ke
This formula uses 1 Functions, 2 Variables
Functions Used
ln - Natural logarithm function (base e), ln(Number)
Variables Used
Elimination Half Life - (Measured in Second) - Elimination Half Life is the time required for the concentration of the drug to reach half of its original value.
Elimination Rate Constant - (Measured in 1 Per Second) - Elimination Rate Constant is the rate at which a drug is removed from the body.
STEP 1: Convert Input(s) to Base Unit
Elimination Rate Constant: 0.058 1 Per Hour --> 1.61111111111111E-05 1 Per Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
tb/2 = ln(2)/ke --> ln(2)/1.61111111111111E-05
Evaluating ... ...
tb/2 = 43022.9284485484
STEP 3: Convert Result to Output's Unit
43022.9284485484 Second --> No Conversion Required
43022.9284485484 Second <-- Elimination Half Life

## 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.
