Description
Atosiban Acetate Product Overview
Atosiban (C43H67N11O12S2) is a synthetic cyclic peptide, related in structure to Oxytocin Acetate but acting as its antagonist. As the acetate salt, it is a white to off-white lyophilized powder that dissolves in water.
In addition, pharmaceutical companies use it in solutions and concentrates for intravenous infusion in obstetric care, where it competes with oxytocin at its receptor. It remains authorized in the EU and many other countries, whereas it is not marketed in the United States. Similarly, related obstetric peptides in our range include Carbetocin.
Because it is injected, key quality parameters include HPLC purity, peptide content, acetate content as well as bacterial endotoxins. Zyntex therefore supplies it only to licensed pharmaceutical companies with sterile production capabilities.
