Complete Guide to Dupilumab Population Pharmacokinetics
Overview
Dupilumab Population is a mAb used in the Immunology therapeutic area. It is indicated for Atopic Dermatitis. Full population PK model for dupilumab (Dupixent). Explore weight-based dosing and target-mediated disposition.
Mechanism of Action
Dupilumab Population exerts its pharmacological effect by targeting IL-4Rα. As a mAb, it modulates this target to achieve therapeutic efficacy in Atopic Dermatitis. Understanding the target engagement is critical for interpreting the pharmacokinetic-pharmacodynamic (PK/PD) relationship and optimizing dosing regimens.

| CL F | 0.34 L/day |
| Vc F | 4.1 L |
| Vmax | 0.41 mg/day |
| dose | 300 mg SC q2w |
| ka SC | 0.19 day⁻¹ |
| t half | ~26 days (at steady state) |
| target | IL-4Rα |
| bioavailability SC | 0.64 |
Parameters represent typical population estimates from published literature. Individual values may vary.
Dosing & Administration
Dupilumab Population is administered via the SC route. Subcutaneous administration provides sustained absorption from the injection site. Bioavailability and absorption rate may vary by injection site and volume.
Dosing recommendations should always follow approved prescribing information. The interactive simulator allows you to explore different dosing scenarios and their impact on drug exposure metrics such as AUC, Cmax, and Ctrough.
