Elimination Rate Constant of Drug Solution

STEP 0: Pre-Calculation Summary

Formula Used

Elimination Rate Constant = ln(2)/Elimination Half Life
k_e = ln(2)/t_b/2
This formula uses 1 Functions, 2 Variables

Functions Used

ln - The natural logarithm, also known as the logarithm to the base e, is the inverse function of the natural exponential function., ln(Number)

Variables Used

Elimination Rate Constant - (Measured in 1 Per Second) - Elimination Rate Constant is the rate at which a drug is removed from the body.
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.

STEP 1: Convert Input(s) to Base Unit

Elimination Half Life: 12 Second --> 12 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

k_e = ln(2)/t_b/2 --> ln(2)/12

Evaluating ... ...

k_e = 0.0577622650466621

STEP 3: Convert Result to Output's Unit

0.0577622650466621 1 Per Second -->207.944154167984 1 Per Hour (Check conversion here)

FINAL ANSWER

207.944154167984 ≈ 207.9442 1 Per Hour <-- Elimination Rate Constant

(Calculation completed in 00.004 seconds)

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.
