What percentage of an originally administered intravenous dose of a drug remains in the body following three half-lives? The correct answer is 12.5%. Please show how this question is solved.
Homework Answers
After 1 half life,the concentration of drug will be half of the initial dose.
For example : 100mg of intravenous drug with half life of 15 minutes.
* 15 min after drug administration,50mg of drug remain in the body (50%).
*30 min after drug administration, 25mg of drug remain in the body (25%)
* 45min after drug administration, 12.5mg of drug remain in the body (12.5%).
After 3 half lives,12.5% of drug remain in the body.

A Phase 1 clinical trial reported that drug elimination following a single intravenous bolus dose was biphasic with drug concentrations described by the following equation: C(t)=163.3 (μg/L) × e-0.8066 hr-1 × t + 22.2 (μg/L) × e-0.0564 hr-1 × t Assume drug elimination occurs from both the central and peripheral compartments. What is the terminal elimination half-life of this drug? NOTE: Please provide your answer in units of hours (hr). Do not include the units in your answer.
