Romiplostim contains four copies of a small peptide that binds with high affinity to the thrombopoietin receptor, grafted onto an immunoglobulin scaffold. It binds to and activates the thrombopoietin (TPO) receptor, thereby increasing platelet production.

Indications

Dosing

Adult
Administered weekly by subcutaneous injection, starting with a dose of 1 μg/kg, titrated until platelet count increases above 50,000/μL.
Max dose
10 μg/kg
