Pazinaclone is a non-benzodiazepine (GABAA) partial agonist with sedative and anxiolytic activity.


| Description | Pazinaclone is a non-benzodiazepine (GABAA) partial agonist with sedative and anxiolytic activity. |
| In vivo | Pazinaclone (5 mg/kg; oral; rats, mice, hamsters, and guinea pigs) unchanged drug concentration in plasma was highest in mice (AUC; 90 ng/h/ml), followed in decreasing order by guinea pigs (AUC; 41 ng/h/ml), hamsters (AUC; 18 ng/h/ml), and rats (AUC; 17 ng/h/ml). Among rabbits, dogs, and monkeys, the dogs had the highest plasma drug concentrations: AUCs of pazinaclone in dogs and monkeys were 1035 and 458 ng. h/ml, respectively (drug concentration in rabbit plasma was very low). Of the two polymorphs, forms 1 and 2 with particle size of < or = 5 microns, the oral absorption of form 2 in rats was more efficient than that of form 1 at 1000 mg/kg: AUCs of pazinaclone after dosing of form 1 and 2 were 489 and 965 ng.h/ml, respectively.[2] |
