NCS-382 (100, 300, 500 mg/kg; i.p.) shows at a dose of 100 mg/kg has a maximum serum concentration that is 4 times that of the brain and 10 times that of the kidney, and a maximum liver concentration that is more than 700% higher than the serum in mouse model[1].
At a dose of 500 mg/kg, it may preferentially reside in the liver after intraperitoneal administration in mouse model[1].
At a dose of 500 mg/kg, brain permeability improves, as evidenced by an increase in brain serum ratio in mouse model[1].
NCS-382 (0.83-2.08 mmol/kg; i.p.) reduces GHB-induced increases in the time mice spent immobile in the forced swim test, indicating anti-sedative activity, when administered at doses of 1.66 and 2.08 mmol/kg in mice model[3].
NCS-382 (2.3 mmol/kg; i.p.) decreases spike and wave discharges in audiogenic seizure-susceptible Swiss Rb mice, as well as a rat model of petit mal epilepsy [4].

| Animal Model: | GBL induced mouse model[1] |
| Dosage: | 300 mg/kg(Combined with diclofenac (25 mg/kg)) |
| Administration: | Intraperitoneal injection (i.p.), Thirty minutes later, mice were given an i.p. injection of GBL (100 mg/kg diluted in PBS) |
| Result: | In the presence of diclofenac, it was highly protective against GBL mediated responses. |
| Animal Model: | GBL induced mouse model[3] |
| Dosage: | 0.83, 1.25, 1.66, 2.08mmol/kg |
| Administration: | Intraperitoneal injection (i.p.), 30 min before the test |
| Result: | At a dosage of 2.08 mmol/kg, completely blocked the effect of GHB when administered at 3.18 mmol/kg |
