Alpha-Adrenergic Blockers
USES
Alpha-Adrenergic Blockers are used for benign prostatic hyperplasia, pheochromocytoma,
prevention of tissue necrosis and sloughing associated with extravasation of IV vasopressors
Alpha-Adrenergic Blockers
ACTION
Alpha-Adrenergic Blockers act by binding to Alpha-Adrenergic receptors, causing dilation of
peripheral blood vessels
-Lower peripheral resistance = decreased B/P
Alpha-Adrenergic Blockers
THERAPEUTIC USE
decrease B/P
increase peripheral pulses
Alpha-Adrenergic Blockers
CONTRAINDICATIONS
Hypersensitive reactions may occur, and allergies should be identified before these products are
given.
