Ganirelix (Antagon) vs Pasireotide (Signifor)
An educational, source-based comparison of Ganirelix (Antagon) and Pasireotide (Signifor) — how each peptide works, what it's researched for, and what to know before going deeper.
Decapeptide GnRH antagonist that rapidly suppresses pituitary LH/FSH release, used during ovarian stimulation to prevent premature ovulation.
- IVF / assisted reproduction
- • FDA-approved.
- • Generally well-tolerated; mild injection reactions.
Multi-receptor somatostatin analog for Cushing's disease and acromegaly.
Cyclohexapeptide somatostatin analog binding somatostatin receptors SST1, 2, 3, and 5 (with highest affinity for SST5), suppressing ACTH in corticotroph adenomas and GH/IGF-1 in somatotroph tumors.
- Cushing's disease
- Acromegaly (LAR formulation)
- • FDA-approved.
- • Significant hyperglycemia risk requires glucose monitoring.
- • Bradycardia and QT prolongation possible.
