Noradrenaline - or norepinephrine, if you prefer - is a well-known endogenous catecholamine involved in many functions of the organism. More in detail, it is an important neurotransmitter, characteristic of the sympathetic nervous system and, as such, capable of interacting with receptors adrenergic, both alpha and beta type.
When it binds to its receptors, noradrenaline is able to influence the activity of different organs and tissues; for example, it induces an increase in heart rate, increases blood flow to skeletal muscles, increases the release of glucose from energy reserves.
The use of noradrenaline as a drug is justified by the action it is capable of carrying out in the cardiovascular system. However, it should be noted that in drugs administered parenterally, noradrenaline is not found pure, but in the form of noradrenaline tartrate.
