Phase 4 trial

Q: What is Phase 4 trial of any given drug?

Answer:  Relatively less publicised and less talked is the evaluation of a drug profile after it is approved and already in the market for patients. It looks over the time the efficiency and the side effects of a new drug/treatment. Usually, it is carried out over a longer period of time and look over thousands of patients.
