Each pre-filled syringe contains Semaglutide INN 1 mg in 0.5 ml solution for injection. Fitaro is a glucagon-like peptide-1 (GLP-1) receptor agonist with 94% sequence similarity to human GLP-1. It selectively binds to and activates the GLP-1 receptor, regulating appetite, enhancing glucose-dependent insulin secretion, suppressing glucagon secretion, slowing gastric emptying, and promoting satiety.
