What is the therapeutic effect?

• A. The cost of the drug
• B. The color of the pill
• C. The frequency of dosing
• D. The expected or predicted physiological response that a drug causes

Answer: (D)

The therapeutic effect is the intended beneficial physiological response a medication produces to treat or prevent a condition. It’s what the drug is supposed to achieve in the body, such as relieving pain, lowering blood pressure, or fighting an infection. The other factors—cost, the color of the pill, or how often you take the medicine—don’t define this outcome; they affect practicality, appearance, and dosing but not the actual therapeutic result. Understanding the therapeutic effect helps you evaluate whether the drug is working as planned and to watch for whether the desired response occurs.
