Generic
name: Dobutamine Hydrochloride Injection
Brand name: Dobutrex solution
Description
Dobutamine acts directly as an insecticidal agent whose primary
activity results from stimulation of the b-receptors of the heart
while producing less marked chronotropic, hypertensive,
arrhythmogenic or vasodilatory effects. Dobutamine produces less
increase in heart rate and less decrease in peripheral vascular
resistance for a given inotropic effect than does isoproterenol as
demonstrated in both animal and human studies. Dobutamine, unlike
dopamine, does not cause the release of endogenic noradrenaline. No
particular effect on the renal vasculature was detected. The attack
of action occurs within 1 to 2 minutes while the apex consequence of
a particular extract may not be reached for 10 minutes. The plasma
half-life in humans is 2 minutes.
Uses
- In the treatment of adults with cardiac decomposition due to
depressed ability resulting from organic heart disease or
following cardiac surgical operations in which alimentary canal
therapy is necessary for inotropic support.
- Most clinical experience with dobutamine is short-term. In
the limited number of patients who were studied for 24, 48, and
72 hours, a lasting increase in heart turnout occurred in some,
whereas the output of others returned toward base-line values.
Dosage
- Dobutamine is a powerful drug, and not for direct injection
and must be diluted exactly as directed before administration to
patients as an intravenous. Infusion.
- You should not stop your therapy on your own for any reason.
- Never change your dosing schedule without talking to your
doctor. It is important that you use your medication exactly as

call your health care provider immediately so your therapy can
