Pharmacology

Indication

Echocardiography: Sulfur hexafluoride is indicated for use in adult patients with suboptimal echocardiograms to opacify the left ventricular chamber and to improve the delineation of the left ventricularendocardial border. Ultrasonography of the Liver: Sulfur hexafluoride is indicated for use with ultrasound of the liver in adult and pediatric patients to characterize focal liver lesions.

Pharmacodynamics

Sulfur hexafluoride provides useful echocardiographic signal intensity for two minutes after the injection. Sulfur hexafluoride microspheres are destroyed and contrast enhancement decreases as the mechanical index increases (values of 0.8 or less are recommended). For ultrasonography of the liver, Sulfur hexafluoride provides dynamic patterns of differential signal intensity enhancement between focal liver lesions and liver parenchyma during the arterial, portal venous, and late phase of signal intensity enhancement of the microvasculature.

Mechanism of action

Within the blood, the acoustic impedance of Lumason microspheres is lower than that of the surrounding non-aqueous tissue. Therefore, an ultrasound beam is reflected from the interface between the microspheres and the surrounding tissue. The reflected ultrasound signal provides a visual image that shows a contrast between the blood and the surrounding tissues.

Absorption

The pharmacokinetic of the SF6 gas component of Lumason was evaluated in 12 healthy adult subjects (7 men and 5 women). After intravenous bolus injections of 0.03 mL/kg and 0.3 mL/kg of Lumason, corresponding to approximately 1 and 10 times the recommended doses, concentrations of SF6 in blood peaked within 1 to 2 minutes for both doses.

Volume of distribution

In a study of healthy subjects, the mean values for the apparent steady-state volume of distribution of SF6 were 341 L and 710 L for Lumason doses of 0.03 mL/kg and 0.3 mL/kg, respectively. Preferential distribution to the lung is likely responsible for these values.

Protein binding

Not Available

Metabolism

SF6 undergoes little or no biotransformation; 88% of an administered dose is recovered unchanged in expired air.

Route of elimination

The SF6 component of Lumason is eliminated via the lungs.

Half-life

The terminal half-life of SF6 in blood was approximately 10 minutes for the 0.3 mL/kg dose. (At the 0.03 mL/kg dose, terminal half-life could not be estimated.)
