For more on marking an answer as the "Best Answer", please visit our FAQ.all drugs are tested against a control (placebo). the drug must work better or more often than a placebo. this does not mean that the drug will always work on every person or discount a psychosomatic effect in some people. It just means that the drug is statistically better than the placebo. Many other factors must also be considered such as:
- how the drug is administered
- personal factors: age, weight, hight etc
- reaction with other drugs
- loads of other things
