Question

(a) The subjects do not know which study treatment they receive

(b) Patients injected with placebo and active doses

(c) Fake treatment

(d) Signed document of the recruited patient for the clinical trial procedures

This question was addressed to me during an online exam.

My question is based upon Controlled Release Medication topic in division Controlled Release Medication of Drug Biotechnology

Answer 1

The correct choice is (c) Fake treatment

The explanation is: The use of a placebo (fake treatment) allows the researchers to isolate the effect of the study treatment. It allows the researchers to see the effect on the patients or the healthy individual when they don’t get the drug rather they get a fake treatment. In this kind of study, all patients are given both placebo and active doses in alternating periods of time during the study.
