pudexacianinium

The chloride salt form of pudexacianinium, an optical imaging agent and derivative of indocyanine green (ICG), a nontoxic, fluorescent, tricarbocyanine dye with a peak spectral absorption at 790 nm, that can be used for near-infrared (NIR) imaging using a NIR fluorescence (NIR-F) medical device. Upon intravenous administration, pudexacianinium is primarily and rapidly excreted by the kidneys. This provides visualization of the ureter(s) during surgery upon NIR-F imaging. Ureter visualization decreases ureter injuries during abdominopelvic surgery.
