| Description | NS 1209 (SPD 502) is a AMPA receptor antagonist. |
| In vivo | NS1209能够在电流诱导的SE的大鼠模型中,以多达50 mg/kg的剂量安全给药,随后通过静脉输注5 mg/kg持续至24小时。通过给予10-50 mg/kg的剂量(腹腔注射或静脉注射)作为脉冲剂量,接着以每小时4或5 mg/kg的剂量(静脉注射)输注2-24小时,能有效地在30-60分钟内终止所有动物的电流诱导的SE,并且在24小时输注后没有出现SE的复发。通过静脉注射,10或30 mg/kg的NS1209同样能够阻断由卡那霉素诱导的SE。为了比较NS1209与地西泮(DZP)的有效性和神经保护效果,一组大鼠接受了地西泮治疗(20 mg/kg,腹腔注射,6小时后再次注射10 mg/kg)。通过使用上述给药方案,NS1209的抗惊厥效果比DZP更快、更全面。NS1209的治疗(20 mg/kg脉冲剂量,随后以每小时5 mg/kg输注24小时)对抗SE引起的海马区神经退行性保护作用存在,但相较于DZP,效果较小。 |
