Selumetinib(Koselugo) has demonstrated significant clinical efficacy as a kinase inhibitor in pediatric patients with neurofibromatosis type 1 (NF1) who are 2 years of age and older with symptomatic, inoperable plexiform neurofibromas (PN). However, in order to maximize its efficacy and minimize side effects, patients and families must strictly follow its dosage and precautions.

Selumetinib dosage

The recommended dosage and administration of Selumetinib is key to ensuring efficacy. Here's a closer look at its usage.

Recommended dose

The recommended dose of Selumetinib is 25 mg/m² orally twice daily (approximately every 12 hours) until disease progression or unacceptable toxicity. This dose is calculated based on the patient's body surface area (BSA) and varies from one BSA patient to another.

Time to take

Patients should take Selumetinib on an empty stomach, i.e., do not eat 2 hours before each dose or 1 hour after each dose. This ensures optimal absorption of the drug in the body.
