What does drug tolerance refer to?

• A. Increased effectiveness of a drug over time
• B. Change in effectiveness at the same dose
• C. Developing new side effects
• D. Immediate sensitivity to the drug

Answer: (B)

Drug tolerance refers to the phenomenon where the body becomes accustomed to a drug over time, resulting in a reduced response to its effects. This means that with continued use of the same dose, the individual may notice that the drug is not as effective as it once was in producing the desired effects. As a result, a higher dose may be needed to achieve the original effect, which can pose risks, including potential overdose or increased side effects. Understanding drug tolerance is crucial for medication management, as healthcare professionals need to monitor patients for changes in efficacy and adjust dosages accordingly. This concept highlights the importance of evaluating and reassessing treatment regimens regularly to ensure that the patient receives the most effective care.
