What do we test drugs for in trials?

• A. Toxicity, efficacy and dose
• B. Color and packaging
• C. Safety and cost
• D. Side effects only

Answer: (D)

Drug trials are designed to learn three things: safety (toxicity), whether the drug actually helps (efficacy), and how to use it (the right dose and dosing schedule). Safety data tell us what harmful effects can occur and at what doses; efficacy shows whether there is a real therapeutic benefit; dosing studies determine the amount and frequency that give benefits with acceptable risk. Side effects are part of safety, but focusing only on side effects ignores whether the drug works and what dose is appropriate. Other options miss either the benefit or the dosing aspect, or bring in irrelevant factors like packaging or cost.
