Clinical testing of pharmaceutical drugs is highly important. Drugs should undergo clinical trials to investigate their effect in the subjects, as well as any other changes such as secondary effects or healing curve. Even if you have the idea that pharmaceutical drugs won’t improve your condition, would you want to take it not knowing secondary effects? or in what another way it could affect you?
The clinical testing is key to demonstrate this so that customers are aware of what they are ingesting. For doctors, it can be very helpful to determine if a patient should take certain drugs or not because through the testing the professional will know if the patient can be helped or should avoid because of certain side effects.
