Drug Rate Entering Body Solution

STEP 0: Pre-Calculation Summary

Formula Used

Absorption Rate Constant = ln(2)/Absorption Half Life
k_a = ln(2)/t_a/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

Absorption Rate Constant - (Measured in 1 Per Second) - Absorption Rate Constant is the rate at which a drug enters into the body for oral and other extravascular routes.
Absorption Half Life - (Measured in Second) - The Absorption Half Life is the time for the concentration of the drug to double its original value for oral and other extravascular routes.

STEP 1: Convert Input(s) to Base Unit

Absorption Half Life: 0.69 Second --> 0.69 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

k_a = ln(2)/t_a/2 --> ln(2)/0.69

Evaluating ... ...

k_a = 1.0045611312463

STEP 3: Convert Result to Output's Unit

1.0045611312463 1 Per Second -->3616.42007248667 1 Per Hour (Check conversion here)

FINAL ANSWER

3616.42007248667 ≈ 3616.42 1 Per Hour <-- Absorption 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.

How to Calculate Drug Rate Entering Body?

Drug Rate Entering Body calculator uses Absorption Rate Constant = ln(2)/Absorption Half Life to calculate the Absorption Rate Constant, The Drug Rate Entering Body formula is defined as the inverse relation of time with the rate constant. Absorption Rate Constant is denoted by k_a symbol.

How to calculate Drug Rate Entering Body using this online calculator? To use this online calculator for Drug Rate Entering Body, enter Absorption Half Life (t_a/2) and hit the calculate button. Here is how the Drug Rate Entering Body calculation can be explained with given input values -> 1.3E+7 = ln(2)/0.69.

FAQ

What is Drug Rate Entering Body?
