Study Notes
Adrenergic Agonists
- Adrenergic agonists increase the sympathetic nervous system response.
Direct-Acting Adrenergic Agonists
- Directly stimulate receptors, examples include alpha-adrenergic agonists and beta-adrenergic agonists.
- Dobutamine is a beta-adrenergic agonist.
- Alpha-adrenergic receptor agonists are used as pressor agents to treat shock.
- Salbutamol is a selective β2 receptor agonist used for bronchodilation.
Indirect-Acting Adrenergic Agonists
- Increase the release of norepinephrine, an example is Amphetamine.
- Promote the release of norepinephrine via reverse action of plasma membrane transporter Na+.
Treatment of Specific Conditions
- Phenylephrine is used for the treatment of nasal congestion.
- Dobutamine increases the heart's contractility and heart rate, increasing cardiac output.
- Terbutaline is used for bronchodilation.
Sympatholytic Drugs
- Phenoxybenzamine is used for the treatment of pheochromocytoma.
- Prazosin is a receptor antagonist used for benign prostatic hypertrophy.
Other Clinical Uses
- Methyldopa is used as an antihypertensive agent.
- Mydriasis is used to dilate the pupils.
- Low-dose dopamine increases renal blood flow and blood flow to the kidneys.

Description
Test your knowledge on drugs affecting the autonomic nervous system (ANS) and how they influence its functions. Explore the classification of autonomic pharmacology into categories such as sympathetic and parasympathetic nervous system responses, and the effects of various drugs on each.
