Sample
use - Physiological Pharmacology
Response
to Alpha Adrenergic Blockade
Administer
phenoxybenzamine (alpha blocker)
(alpha receptors mediate 'sympathetic" vascular constriction)
Changes in Key Variables
 Arterial
Pressure |
Drops precipitously- vascular smooth muscle relaxes due to blockade |
 Peripheral
Resistance |
TPR falls sharply due to blockade |
 Skin
blood flow |
Drops due to skin vessel relaxation |
 Vascular
conductance |
Ease of flow rises due to the blockade |
