Adrenergic drugs

ADRENERGIC DRUGS (sympathomimetics)

Drugs acting on adrenergic nervous system

• Two groups:
  • Adrenergic agonists (sympathomimetic)
  • Adrenergic antagonists (sympatholytic)
• Adrenergic agonists- Produce actions similar to that of adrenaline and noradrenaline and hence their pharmacological effects are similar to those observed when sympathetic nerve is stimulated. These are also called sympathomimetic drugs.
• Anti adrenergic drugs are those drugs that interfere with the actions of sympathetic nervous system stimulation. These drugs are also called sympatholytic drugs.
