Pegvisomant (Somavert) vs Rezafungin (Rezzayo)
An educational, source-based comparison of Pegvisomant (Somavert) and Rezafungin (Rezzayo) — how each peptide works, what it's researched for, and what to know before going deeper.
Pegylated GH receptor antagonist for acromegaly.
Genetically engineered analog of human GH with site-directed mutations blocking functional dimerization of the GH receptor; pegylation extends half-life. Lowers IGF-1 without lowering GH.
- Acromegaly inadequately controlled by surgery, radiation, or somatostatin analogs
- • FDA-approved.
- • Monitor LFTs; tumor monitoring via MRI required.
- • Lipohypertrophy at injection sites.
Once-weekly echinocandin for candidemia and invasive candidiasis.
Next-generation echinocandin structurally related to anidulafungin with enhanced stability, inhibiting β-(1,3)-D-glucan synthase; long half-life permits once-weekly IV dosing.
- Candidemia
- Invasive candidiasis
- • FDA-approved (2023).
- • Infusion reactions and photosensitivity reported.
