Biodistribution & persistence
Extensive distribution in rats, highest in adrenal, fat, skin, ovary, pancreas and kidney; crosses blood-brain barrier
“Following IV administration of cipepofol injectable emulsion, extensive tissue distribution was observed in Sprague-Dawley rats, with the highest exposures found in the adrenal gland, fat, skin, ovary, pancreas, and kidney. Cipepofol was demonstrated to cross the blood-brain barrier.”

Modality-specific risk
Exaggerated pharmacology (respiratory depression, anesthesia-related mortality) and QTc prolongation
“Several adverse findings were identified from the nonclinical studies but were generally attributed to the pharmacological effects of the active pharmaceutical ingredient (e.g., muscle relaxation, respiratory depression, anesthesia related mortality) or can be clinically monitored (e.g., QTc prolongation, local irritation).”
