The principal mechanism of phentolamine-induced tachycardia is:
Antagonism of presynaptic alfa2 receptors enhances norepinephrine release, which causes cardiac stimulation via unblocked beta receptors Baroreflex mechanism Direct effect on the heart by stimulation of beta1 receptors Inhibition of transmitter reuptake at noradrenergic synapses |
|
View Answer |
|
The main reason for using alfa-receptor antagonists in the management of pheochromocytoma is:
Inhibition of the release of epinephrine from the adrenal medulla Blockade of alfa2 receptors on vascular smooth muscle results in epinephrine stimulation of unblocked alfa2 receptors Direct interaction with and inhibition of beta2 adrenoreceptors Antagonism to the release of rennin |
