(b) Patients injected with placebo and active doses

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

I have been asked this question by my school principal while I was bunking the class.

This interesting question is from Controlled Release Medication in section Controlled Release Medication of Drug Biotechnology

Answer 1

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

To elaborate: The subjects involved in the study do not know which study treatment they receive. If the study is double-blind, the researchers also do not know which treatment is being given to any given subject. In this kind of study the subjects or the patients will not be knowing which study treatment they receive.
