What is the therapeutic range for carbamazepine (Tegretol)?
Correct Answer: B
Rationale: The therapeutic range for carbamazepine is 4-10 mcg/mL, which ensures effective seizure control while minimizing toxicity.
Option A (7-12 mcg/mL) is incorrect as it exceeds the upper limit of the established therapeutic range, potentially leading to adverse effects.
Option C (10-14 mcg/mL) also exceeds the therapeutic limit, increasing the risk of side effects and toxicity.
Option D (1-5 mcg/mL) is too low, as it falls below the minimum effective concentration, likely resulting in inadequate seizure control. Understanding the correct therapeutic range is crucial for safe and effective treatment.
