What term describes a drug's ability to effectively kill infectious pathogens?

• A. Dose
• B. Efficacy
• C. Placebo
• D. Trial

Answer: (B)

Efficacy is about how well a drug achieves its intended therapeutic effect, such as effectively killing infectious pathogens when given at a suitable dose. It captures the maximum benefit the drug can provide in eliminating or reducing the pathogen. Dose describes how much drug is given and can influence the level of effect but doesn’t define the drug’s ability to work. A placebo is an inactive substance, used as a control. A trial is a study to test safety and effectiveness. So, the term that best describes a drug’s ability to effectively kill pathogens is efficacy.
