What is the difference between dopamine and dobutamine?

Dopamine is typically used in the treatment of septic shock or cardiogenic shock. Dobutamine is a drug that primarily stimulates beta-1 receptors, leading to increased inotropic and chronotropic effects. to al lesser extent, dobutamine also stimulates beta-2 adrenergic receptors, leading to vasodilatation.
