Gadopiclenol

Gadopiclenol, sold under the brand name Elucirem among others, is a contrast agent used with magnetic resonance imaging (MRI) to detect and visualize lesions with abnormal vascularity in the central nervous system and in the body.[1] Gadopiclenol is a paramagnetic macrocyclic non-ionic complex of gadolinium.[1]

Gadopiclenol was approved for medical use in the United States in September 2022.[1][3][4]

Names

Gadopiclenol is the international nonproprietary name (INN).[5]

Pharmacology

Gadopiclenol has a higher relaxivity compared with standard gadolinium-based contrast agents (GBCAs). The higher relaxivity allows for a lower dose of gadopiclenol, reducing the total amount of gadolinium administered to the patient while preserving imaging quality. Gadopiclenol was approved by the FDA with a recommended dose of 0.05 mmol/kg for adults and pediatric patients aged 2 years and older. This is half the dose of standard macrocyclic GBCAs, which have a recommended dose of 0.1 mmol/kg.[1][6][7]
