Bottom line
Voclosporin is a synthetic analog of cyclosporine A modified at the amino acid-1 residue (the MeBmt position). It is a homodetic cyclic peptide and a calcineurin inhibitor. FDA-approved in January 2021 (Lupkynis) for the treatment of active lupus nephritis in combination with mycophenolate mofetil and corticosteroids. A pivotal phase 3 trial (AURORA-1) demonstrated superior renal response rates compared to standard of care. Unlike cyclosporine, voclosporin does not require therapeutic drug monitoring.

An unsupported assumption about performance effect is not a basis for classification; athletes should verify the exact product and current status.
Mechanism and pharmacology
Voclosporin binds to cyclophilin A; the complex inhibits calcineurin, blocking IL-2 expression and T-cell-mediated immune responses. It also stabilizes podocytes in the kidney. The single amino-acid modification vs cyclosporine A alters binding affinity to calcineurin, leading to a more predictable How a substance is absorbed, distributed, metabolized, and eliminated by the body; atlas pages report pharmacokinetic data such as half-life, metabolism, and clearance. 定義の出典: Neutral gloss; usage context: Routes, devices, and absorption primer · 用語集 profile and no requirement for therapeutic drug monitoring.

Dose and administration evidence
Approved labeled regimen
The label summary below is product-, indication-, and jurisdiction-specific; consult the full current label and a licensed clinician/pharmacist.
23.7 mg (3 capsules of 7.9 mg) orally twice daily (approximately 12 hours apart).
Avoid use if baseline eGFR ≤45 mL/min/1.73 m² unless benefit outweighs risk.
If eGFR drops to 30–44 mL/min/1.73 m² during treatment: reduce dose to 15.8 mg (2 capsules) BID; if no improvement within 4 weeks, discontinue.
If eGFR drops to <30 mL/min/1.73 m²: discontinue voclosporin.
For severe renal impairment at baseline (eGFR 15–29 mL/min/1.73 m²): starting dose of 15.8 mg BID if used; discontinuation rules apply as above.
On empty stomach (1 hour before or 2 hours after a meal).
In combination with mycophenolate mofetil (MMF) and rapidly tapered corticosteroids.
Studied regimens (not recommendations)

Only physicians experienced in immunosuppressive therapy and management of lupus nephritis should prescribe.
Nephrotoxicity: eGFR reduction (typically reversible).
Hypertension.

Breastfeeding: not recommended.
