The urinary excretion of the unchanged drug is directly proportional to the plasma concentration of a drug.

The urinary excretion of the unchanged drug is directly proportional to the plasma concentration of a drug. Correct Answer True

Urinary excretion studies help in assessing bioavailability is based on the principle that urinary excretion of unchanged drug is directly proportional to the plasma concentration of a drug. If a drug is excreted at least 10 to 20% in the urine, bioavailability can be determined.
