How long does drug discovery usually take?

• A. 2-5 years.
• B. 5-7 years.
• C. 1-2 years.
• D. 6-10 years.

Answer: (A)

Drug discovery, the phase where scientists identify a target, screen compounds, and optimize leads, typically spans a few years. Most projects require multiple rounds of screening, structure-activity optimization, and early ADME/toxicity work before a lead candidate is ready for preclinical testing. Because of this complexity, 2-5 years is the common range. Times shorter than this happen only in very straightforward or repurposing cases, while longer spans (like 6-10 years) usually reflect extended development beyond discovery. So the best answer is 2-5 years.
