Noradrenaline tartrate is an effective adrenergic receptor agonist that activates α1, α2, and β1 receptors. It is a precursor of epinephrine and serves as the principal neurotransmitter of most postganglionic sympathetic fibers and the diffuse projection system in the brain originating from the locus coeruleus, and can be used to establish cardiomyopathy models.
