Molecular reference: gadopiclenol
PubChem CID 16223405Molecular formula: C35H54GdN7O15
Mechanism of action
Gadopiclenol is a macrocyclic non-ionic complex of gadolinium and a paramagnetic molecule that develops a magnetic moment when placed in a magnetic field. The magnetic moment alters the relaxation rates of water protons in its vicinity in the body. Its use in magnetic resonance imaging (MRI) allows to selectively increase contrast in tissues where gadopiclenol accumulates.
Pharmacodynamics
Variations in radiofrequency signal intensity allow the visualization of normal and pathological tissues during magnetic resonance imaging (MRI). These variations occur due to differences in proton density, differences of the spin-lattice or longitudinal relaxation times (T1), or differences in the spin-spin or transverse relaxation time (T2). Gadopiclenol shortens the T1 and T2 relaxation times and allows the visualization of targeted tissues during an MRI. The extent to which a contrast agent can affect the relaxation rate of tissue water (1/T1 or 1/T2) is termed relaxivity (r1 or r2). Gadopiclenol has a high r1 relaxivity compared to other gadolinium-based contrast agents. The use of gadopiclenol is not associated with QT interval prolongation; however, it can increase the risk for nephrogenic systemic fibrosis in patients with impaired elimination of the drugs. The use of gadopiclenol may also cause hypersensitivity reactions and acute kidney injury.
