Which statement about weight-based dosing for pediatric triptans is true?

• A. Dose is determined by body weight to tailor exposure.
• B. Dose is identical for all children.
• C. Dose is based on age only.
• D. Dose is adjusted randomly.

Answer: (A)

Weight-based dosing is used in kids to tailor drug exposure because a child’s body size and developmental stage markedly influence how a triptan is handled by the body. Dosing per kilogram helps achieve systemic exposure similar to that seen in adults, reducing the risk of underdosing (ineffective relief) or overdosing (more side effects). Simply using age alone ignores substantial differences in body weight and maturation, and dosing randomly would be unsafe. That’s why the true statement is that dose is determined by body weight to tailor exposure.
