Regarding proteins:

• Adrenergic receptor, a receptor type for epinephrine and norepinephrine; subtypes include α₁, α₂, β₁, β₂, and β₃ receptors
• Adrenergic transporter (norepinephrine transporter), a protein transporting norepinephrine from the synaptic cleft into nerve cells

Regarding pharmaceutical drugs:

• Adrenergic receptor agonist, a type of drug activating one or more subtypes of adrenergic receptors
  • This includes drugs regulating blood pressure and antiasthmatic drugs.
• Adrenergic receptor antagonist, a type of drug blocking one or more subtypes of adrenergic receptors
  • This mainly includes drugs lowering blood pressure.
• Adrenergic reuptake inhibitor, a type of drug blocking the norepinephrine transporter
  • This includes antidepressants and drugs against ADHD.
