Noradrenaline bitartrate monohydrate is an agonist of adrenergic receptors, with Ki values of 330, 56 and 740 nM for α1, α2 and β1 adrenoceptors, respectively [1].
Noradrenaline is a neurotransmitter distributed in both the peripheral and central nervous systems. In the autonomic nervous system, noradrenaline acting at α1-receptors causes constriction of cutaneous blood vessels. In the central nervous system, noradrenaline found primarily in the locus coeruleus in the brainstem, plays important roles in a variety of physiological activities, such as sleep/wake cycles, attention, orientation, mood and memory [2].
In femoral strips isolated from the untreated dogs, noradrenaline bitartrate monohydrate (5 × 10-9 ~ 10-4 M) induced dose-dependent contractions which were inhibited completely by 10-8 M phenoxybcnzamine administered 40 min previously. In the femoral strips isolated from the ephedrine-treated dogs, contractile responses to noradrenaline bitartrate monohydrate were potentiated at low concentrations (5 × 10-9 ~ 10-7 M) but inhibited at high concentrations (5 × 10-7 ~ 10-4 M) [3].
