Randomized Controlled Trial Comparative Study Clinical TrialPharmacodynamic effects of milrinone with and without a bolus loading infusion.
Milrinone is a positive inotropic agent with vasodilatory and lusitropic activity. Milrinone dosed as a 50 microg/kg bolus followed by a continuous infusion provides an immediate and sustained hemodynamic response. The comparative pharmacodynamics of a placebo bolus and a milrinone bolus followed by a continuous milrinone infusion in patients with decompensated heart failure are unknown. ⋯ A milrinone infusion without a bolus appears to be a rapidly effective inotropic strategy that may have an improved safety profile during the initiation of therapy compared with a continuous infusion strategy initiated with a bolus.
