Dobutamine is indicated for heart failure, because it helps alleviate symptoms by activating beta1 receptors on the heart, which increases myocardial contractility and thereby cardiac output.
Dobutamine is indicated for patients with hypotension to increase blood pressure, therefore it would be contraindicated in patients with hypertension.
Tachycardia is a side effect of dobutamine and is not among its therapeutic uses.
Dobutamine is not indicated for asthma, because it is a beta1-adrenergic drug.
