Dales vasomotor reversal
A. Stimulation of alpha-I receptorsB Stimulation of alpha-2 receptors
C. Stimulation of beta-I receptors
D. Stimulation of beta-2 receptors
E. stimulation of beta 3 receptors
The Answer is. (D)
Stimulation of beta-2 receptors
—
Adrenaline acts on a1, a2, β1 and β2 and receptors and weak β3 action while at
low concentration continue to act on β receptor When a-blocker is given to patient on adrenaline the a-blockers block the pressor action
of adren1ine and then it prn4nres only fall in BP due to β2-mediated vasodilation called casomotor reversal of dale.
