Which term describes harmful responses to medication observed during testing?

• A. Toxic Effects
• B. Efficacy
• C. Bioavailability
• D. Adverse Reactions

Answer: (A)

Toxic effects describe the actual harmful biological responses a drug can produce when its toxic potential is reached, which is exactly what toxicology testing aims to identify. These are the damaging outcomes observed during testing as you assess safety at higher or at-risk doses. Efficacy is about the desired therapeutic effect, not harm. Bioavailability concerns how much drug reaches circulation. Adverse reactions are undesirable effects that can occur at various doses, but the term that specifically denotes harmful, toxicity-related responses observed in testing is toxic effects.
