Nitroarginine, or Nω-nitro-L-arginine, is a nitro derivative of the amino acid arginine. It is an inhibitor of nitric oxide synthase and hence a vasoconstrictor. As such, it finds widespread use as a biochemical tool in the study of nitric oxide and its biological effects.^[1]

Nitroarginine has been used in research studying coronary constriction, in the presence of midazolam vasodilatation was unaffected by nitroarginine.^[2]
