| Preferred Name | Alpha-Adrenergic Antagonist |
| Definitions |
Natural or synthetic Alpha-adrenergic Blocking Agents selectively bind to adrenergic receptors, or compete with natural adrenergic mediators, and inactivate alpha adrenergic receptors of the sympathetic nervous system. These agents block the action of natural sympathomimetic neurotransmitters (norepinephrine and related substances), and can initiate physiological responses such as vasodilation, bradycardia, and pupil contraction.

| ALT_DEFINITION | A substance that relaxes muscle tissue in blood vessels and in the prostate gland, which improves the flow of urine and blood. Alpha-blockers are used to treat the symptoms of many conditions, such as benign prostatic hyperplasia (BPH), high blood pressure, and some blood circulation problems.
