... ), suggesting that the baroreceptors will be operative at higher blood pressure levels after ethanol. 4. The pressor responsiveness was also influenced differently by ethanol depending on the method of injecting phenylephrine. An increase in pressor responsiveness was evident, though not dose-related, after...

..., and plasma noradrenaline, 10–20 min after dosing and an associated reduction in heart rate. These observations are consistent with blockade of peripheral presynaptic α 2 −adrenoceptors in man. 3. The pressor responses to α−methylnoradrenaline, which has relatively selective agonist effects on α 2...
