NCT02924454

Brief Summary

The aim of this study is to investigate whether intravenous lipid emulsion is effective in attenuating the clinical effects of a cardioactive drug, exemplified by the beta-blocking agent metoprolol. In addition, the investigators will clarify how intravenous lipid emulsion affects the pharmacokinetic parameters of metoprolol.

Outcome Measures

Primary Outcomes (1)

Interventions

One hundred and twenty ml, 0.5 mg metoprolol/ml (as metoprolol tartrate) is administered as an intravenous bolus injection followed by a continuous infusion. Infusion is halted if heart rate drops below 35 bpm or systolic blood pressure drops below 80 mm Hg, or the participant experiences subjective side effects. Infusion stops at T=30 minutes.

Also known as: metoprolol tartrate, Seloken, ATC: C07AB02
Metoprolol - normal salineMetoprolol-Lipid emulsion

Intravenous lipid emulsion 20 % is administered as an intravenous bolus infusion (1.5 ml/kg) followed by continuous infusion (infusion rate: 0.25 ml/kg/min). Lipid emulsion infusion is stopped at T = 30 minutes.

Also known as: Intralipid, ATC: B05BA02
Metoprolol-Lipid emulsionNormal saline-Lipid emulsion

Isotonic 0.9 % sodium chloride solution is administered as an intravenous bolus infusion (1.5 ml/kg), followed by continuous infusion (infusion rate: 0.25 ml/kg/min). Infusion is stopped at T = 30 minutes.
