Icatibant (Firazyr) vs Romiplostim (Nplate)
An educational, source-based comparison of Icatibant (Firazyr) and Romiplostim (Nplate) — how each peptide works, what it's researched for, and what to know before going deeper.
Bradykinin B2 receptor antagonist for hereditary angioedema attacks.
Synthetic decapeptide that competitively blocks the bradykinin B2 receptor, halting the vascular leak that drives HAE swelling attacks.
- Hereditary angioedema (acute attacks)
- • FDA-approved.
- • Injection-site reactions very common.
Thrombopoietin-receptor peptibody for immune thrombocytopenia.
Peptibody (Fc-peptide fusion) containing TPO receptor-binding peptide domains that activate c-Mpl on megakaryocytes, stimulating platelet production without competing with endogenous TPO.
- Chronic immune thrombocytopenia (ITP)
- Pediatric ITP
- Hematopoietic syndrome of acute radiation
- • FDA-approved.
- • Reticulin fiber deposition in bone marrow; thrombosis risk with over-correction.
