Abstract
The pharmacokinetics of baclofen analyzed by gas chromatography mass spectrometry in a massive intoxication case (baclofen 1230 mg orally) is presented. In contrast to earlier reports, no increase in the plasma half-life of elimination of baclofen could be observed (t ½ = 4.58 hours). On the contrary, we found an increased plasma clearance (Clpl = 0.368 1/kg x h) and a higher volume of distribution (Vdarea = 2.4 1/kg) in this highly intoxicated patient compared to the kinetics usually found in healthy subjects.
