(a) Acute pharmacologic response

(b) Plasma-level time studies

(c) Urinary excretion studies

(d) Stool excretion studies

This question was addressed to me by my college professor while I was bunking the class.

My question is from Bioavailability in chapter Compartment Modelling, Non Linear Pharmacokinetics, Bioavailability and Bioequivalence of Drug Biotechnology

Answer 1

Right answer is (a) Acute pharmacologic response

Explanation: Pharmacodynamic methods are a direct measurement of the drug effect on physiological processes as a function of time. The methods are acute pharmacologic response and therapeutic response. Pharmacokinetics method is indirect methods and these are Plasma level time studies and Urinary excretion studies.
