Use our free Drug Half-Life Calculator to quickly determine the remaining concentration of a medication in the body after a specific time. Understand the crucial concept of pharmacokinetics and how drugs are metabolized and eliminated, aiding in safe and effective dosing strategies.
Formula:
The remaining drug concentration (Ct) is calculated using the first-order elimination formula:
Ct = C0 * (0.5)(t / t½)
Where:
- Ct = Remaining drug concentration after time 't'
- C0 = Initial drug concentration or dose
- t = Time elapsed since initial dose
- t½ = Drug half-life (the time required for the concentration of the drug in the body to reduce by half)
