Question 4

Accepted Answer

Dobutamine: IV medication given primarily for congestive heart failure from heart muscle weakening.  This increases the ability of the heart to contract and increase blood flow throughout the body helping with heart failure symptoms.  Used with diuretic therapy (Lasix) to get extra fluid/water out of the body.  Used in hospital but can be used at home for chronic therapy for end-stage heart failure.

Question 5

which functional groups are there in dobutamine?

Accepted Answer

Beta and alpha: Dobutamine chemically has functional hydroxyl groups attached to benzene rings connected via an imine bridge. What is important functionally is its ability to stimulate beta receptors. Dobutamine stimulates beta 1 >>beat 2> Alpha 1. The causes the heart to work harder and increase cardiac output, at the expense of increasing the heart's oxygeb consumption. Dobutamine also causes vasodilation.

Question 6

Like any medication, it has the potential for side effects (particularly at higher doses) which can include myocardial ischemia and life threatening arrythmias.

Question 8

why is dobutamine given intravenously?

Accepted Answer

No other form: Presently, there is no other form of Dobutamine on the market.  Generally, when Dobutamine is used, one is seeking immediate action of the drug, if the drug was administered through just about any other route, it would take longer to act and the delay in action is not desirable.  This of course excludes CHF patients on chronic Dobutamine pump, my first sentence is directed at them.

Question 9

what is a duel isotope dobutamine test?

Accepted Answer

Cardiac stress Test: This is a form of cardiac stress testing where two different radioactive isotopes are used to visualize the heart muscle at rest and during stress. Dobutamine is a chemical that is used to increase your heart rate and simulate walking on the treadmill.
