Talk:Dobutamine

what is dobutamine test?
Catecholamines reduce cardiac efficiency as they increase oxygen demand without nessesarily increasing output or efficiency. It is therefore not a good choice of drug for shock or heart failure. In this scenario it would only reproduce the undesirable effects of MI where adrenaline is produced. —Preceding unsigned comment added by 77.99.102.107 (talk) 13:40, 12 January 2008 (UTC)

I also think that it's useful in ischemic heart disease, but I might be wrong.

There appears to be a typo: the hypertensive effects of dopamine are due to activity at alpha 1, not dopamine receptors — Preceding unsigned comment added by 66.243.219.231 (talk) 20:12, 14 August 2017 (UTC)

GUC

Also important, is that at high doses, the antihypertensive effect can actually cause hypotension, which is dangerous is some cases- like in hypotension secondary to Right Ventricle STEMI, if fluid resuscitation fails to increase blood pressure, Dobutamine would be a poor choice, especially high doses of it. You'd want to use other inotropics.

--- "Since it does not act on dopamine receptors to inhibit the release of norepinephrine (another α1 agonist), dobutamine is less prone to induce hypertension than is dopamine."

Is this the wrong way around

dopamine receptors to cause the release of norepinephrine ....
