An Adrenergic Antagonist is a drug compound that inhibits the actions of the adrenergic system by blocking adrenergic receptors.
- Context:
- It can be classified based on the type of adrenergic receptor it targets, such as Alpha Adrenergic Antagonists (targeting Alpha Receptors) or Beta Adrenergic Antagonists (targeting Beta Receptors).
- It can work by either blocking the adrenergic receptors or inhibiting norepinephrine release, thus reducing sympathetic nervous system activity.
- It can be used to treat conditions like Hypertension, Heart Arrhythmia, Anxiety, Pheochromocytoma, and Benign Prostatic Hyperplasia.
- It can range from being a Selective Adrenergic Antagonist, targeting specific subtypes of receptors, to being a Non-Selective Adrenergic Antagonist, affecting multiple types of receptors.

- Example(s):
- Alpha Adrenergic Antagonists:
- Prazosin, used to treat hypertension and PTSD.
- Doxazosin, commonly prescribed for benign prostatic hyperplasia.
- Beta Adrenergic Antagonists:
- Propranolol, used for hypertension, anxiety, and heart conditions.
- Metoprolol, mainly used for heart diseases.
