ACTION AND CLINICAL PHARMACOLOGY
MAGNEVIST (gadopentetate dimeglumine) was developed as a contrast
agent for
diagnostic use in magnetic resonance imaging (MRI). Gadolinium is a
rare earth element.
Its ion (Gd
+++
) has seven unpaired electrons and, therefore, shows paramagnetic
properties. Gd
+++
has a strong effect on the hydrogen-proton spin-lattice relaxation
time
(T
1
), which causes the observed contrast enhancement in MRI scans. By
chelation of
Gd+++
with diethylenetriamine pentaacetic acid (DTPA), a strongly
paramagnetic,
well-tolerated,
stable
complex
(gadopentetate
dimeglumine
salt)
is
obtained.
The
paramagnetic efficacy at a magnetic field strength of 1.5 T and at
37°C, as indicated by the
relaxivity (r
1
) (determined from the influence on the T1 relaxation time of the
water protons
in plasma) and the relaxivity (r
2
) (determined from the influence on the T2 relaxation time),
is about 4.1 ± 0.2 L/(mmol•sec) and 4.6 ± 0.8 L/(mmol•sec),
respectively. The relaxivities
display only slight dependency on the strength of the magnetic field.
The free gadolinium ion is unsuitable for clinical use due to high
toxicity; however, the
metal chelate is metabolically inert and does not display significan
