FROM URINE OF HUMAN SUBJECTS ... TAKEN METHYPRYLON ... NEW METABOLITE HAS BEEN ... IDENTIFIED AS 2,4,6-TRIOXO-3,3-DIETHYL-5-METHYLPIPERIDINE. 2,4-DIOXO-3,3-DIETHYL-5-METHYLTETRAHYDROPYRIDINE, 2,4-DIOXO-3,3-DIETHYL-5-HYDROXYMETHYLTETRAHYDROPYRIDINE, & 4,6-DIOXO-5,5-DIETHYL-TETRAHYDRONICOTINIC ACID ... ESTABLISHED AS METABOLITES ...
While the metabolic degradation of methyprylon is known, it is not certain in which organ this takes place. Methyprylon is dehydrogenated to 5-methyl-pyrithyldione, then partially oxidized to hydroxy derivatives, and finally oxidized to 5-carboxy-pyrithyldione. The hydroxy derivatives are bound approximately 38% to human plasma proteins. Other less important metabolites may arise, but the metabolites are partly conjugated to glucuronide, with approximately 97% of the parent drug being metabolized. Intact methyprylon (3%) and its metabolites (60%) are recovered in the urine, while approximately 20% is found in the feces, demonstrating that enterohepatic circulation of the drug occurs.

代谢

半衰期:6-16小时
Hepatic. Methyprylon is almost completely metabolized.
Half Life: 6-16 hours
Methyprylon binds at a distinct binding site associated with a Cl<sup>-</sup> ionopore at the GABA<sub>A</sub> receptor, increasing the duration of time for which the Cl<sup>-</sup> ionopore is open. The post-synaptic inhibitory effect of GABA in the thalamus is, therefore, prolonged.
