Mercaptopurine maintenance in ALL is administered by which route in the described regimen?

Explanation:
Mercaptopurine is given orally in maintenance to maintain steady systemic drug levels with long-term, at-home dosing. The drug has good oral bioavailability and is formulated for daily oral administration, which fits the need for ongoing suppression of leukemic cell growth. Using an oral suspension is especially helpful in younger patients who can’t swallow tablets, allowing accurate dosing by weight or body surface area. Intravenous, subcutaneous, or inhaled routes are not standard for this maintenance therapy, as they are not how this drug is typically delivered and would complicate long-term, at-home treatment.
