چکیده انگلیسی
The ultrasound contrast agent Sonazoid⢠was administered as an i.v. bolus injection of 0.6 μL microbubbles/kg body weight or as a continuous infusion over 30 min at a rate of 1.2 μL microbubbles/kg body weight to healthy volunteers and patients with reduced pulmonary diffusing capacity. Expired air and blood samples were collected from 32 subjects and perfluorobutane (PFB) gas was analyzed using validated gas chromatography mass spectrometry methods. Blood concentrations of PFB declined biphasicly with a distribution half-life (t0.5 to 15) of 2 to 3 min and an elimination half-life (t15 to 120) of 30 to 45 min. Area under the curve (AUC) values in patients with impaired gas diffusion were significantly larger than those in healthy volunteers. The exhalation kinetics were somewhat variable with a PFB elimination half-life (t15 to 120) of 28 to 111 min. Clearance of PFB was independent of study population and mode of administration. There were no deaths and no serious adverse events that resulted in the withdrawal of a subject from the study. With the exception that arthralgia predominated in healthy volunteers, healthy volunteers and diseased subjects did not show a different adverse event profile whether Sonazoid⢠was administered as a bolus injection or as an infusion. Assessment of laboratory parameters (serum biochemistry, haematology and urinalysis), vital signs, oxygen saturation and electrocardiograms (ECGs) showed no changes which caused safety concern.
