Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Gadolinium-based paramagnetic contrast agent. The gadolinium ion (Gd3+) has seven unpaired electrons and a high magnetic moment, which enhances the relaxation rates of surrounding water protons in tissues, increasing signal intensity on T1-weighted magnetic resonance imaging (MRI) scans.
Teslascan is a manganese-based paramagnetic contrast agent that enhances T1-weighted magnetic resonance imaging (MRI). Manganese ions shorten the T1 relaxation time of protons, increasing signal intensity in tissues where it accumulates.
0.2 mL/kg (0.1 mmol/kg) IV bolus; may repeat once within 30 minutes for total dose of 0.4 mL/kg (0.2 mmol/kg) if needed for contrast-enhanced MRI.
0.1 mL/kg (0.1 mmol/kg) intravenous bolus injection.

Terminal elimination half-life is approximately 2 hours in patients with normal renal function. In patients with severe renal impairment (GFR < 30 mL/min), half-life may be prolonged up to 30 hours.
Terminal elimination half-life is 6.2 hours in patients with normal renal function (CrCl > 60 mL/min). In patients with moderate renal impairment (CrCl 30-60 mL/min), half-life increases to 9.5 hours; in severe impairment (CrCl < 30 mL/min), half-life exceeds 15 hours.
Primarily renal excretion via glomerular filtration; >90% of administered dose eliminated unchanged in urine within 24 hours. Less than 1% eliminated in feces.
70% renal (unchanged drug), 30% fecal (biliary excretion).
