What is the drug discovery process?

• A. The process by which pharmaceutical and academic laboratories identify or screen compounds to find potentially therapeutic agents.
• B. The process of marketing a drug to consumers.
• C. The process of manufacturing a drug at scale.
• D. The process of conducting phase III trials.

Answer: (A)

Drug discovery is the process of identifying or screening compounds in pharmaceutical and academic labs to find molecules that could become medicines. It starts with choosing disease-relevant targets, then screening large libraries of chemicals to find substances that affect the target. Hits are validated and optimized into lead compounds, with iterative chemistry and biology work to improve potency, selectivity, and drug-like properties before moving toward preclinical testing. This stage is separate from marketing, which is about commercialization after development; manufacturing, which is producing the drug at scale; and later-stage clinical trials (like Phase III), which test safety and efficacy in patients.
