The pharmacokinetics of ubidecarenone (CoQ10) in rat plasma and the kinetics of its organ levels were studied for the first time for 8-16 d after a single i.v. injection at a dose of 30 mg/kg. The pharmacokinetics followed a classical two-compartment curve. The main pharmacokinetic parameters for plasma (C 0, AUC 0→∞, K α, K el, t 1/2α, t 1/2el, Cl T, V d) and several organs (C max, T max, AUC 0→t , f tiss) were calculated. The results proved that CoQ10 injected i.v. rapidly attained and maintained for a long time high levels in plasma, myocardium, brain, liver, and kidneys. This was potentially important for treating acute ischemic states.
