Dobutamine ballicule: receptor binding, kinetics and half-life diagram — Mechanism of action: Dobutamine ballicule

What it isBeta-1 selective agonist; cardiogenic shock, decompensated heart failure and pharmacological stress testing.

Why this oneRaises contractility more than heart rate at moderate doses, and is titratable within minutes.

What limits itTachyarrhythmia and increased myocardial oxygen demand. Tolerance develops within days; it lowers blood pressure through beta-2 vasodilation.
