What happens if the drug is found to be safe?

• A. It is tested for side effects only
• B. It is discarded
• C. It is approved immediately
• D. Further trials determine the optimum dosage

Answer: (D)

Once a drug is found to be safe, the next step is to determine the optimum dosage. Safety alone doesn’t tell us how much of the drug provides the best balance between benefit and risk, so researchers run dose-ranging studies to see how different amounts affect efficacy and side effects. This helps identify the recommended dose and dosing schedule before any large-scale efficacy trials or regulatory submission. The other options don’t fit: safety testing isn’t limited to side effects only, discarding a safe drug makes no sense, and immediate approval isn’t granted without confirming the right dose and clear efficacy.
