Catecholamine System (N/A)

The catecholamine system refers to the network of molecules, enzymes, receptors, and physiological processes involving catecholamines—biogenic amines that function as both neurotransmitters and hormones in the body. The primary catecholamines are dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline). These molecules are synthesized from the amino acid tyrosine through a well-defined biosynthetic pathway and regulate numerous physiological functions including heart rate, blood pressure, metabolism, movement, emotional responses, and memory. Alterations in the catecholaminergic system are implicated in various diseases, and blood tests for circulating levels of these molecules help diagnose certain endocrine disorders or monitor stress responses.

Drugs targeting the catecholamine system act via various mechanisms, including: (1) influencing catecholamine synthesis, (2) blocking or stimulating catecholamine receptors, (3) inhibiting catecholamine reuptake, or (4) inhibiting catecholamine degradation.
