Abstract
Description
도 1은 로피바카인 조성물(pH 5.5 히스티딘 용액으로 수화됨, 닫힌 사각형; pH 6.0 히스티딘 용액으로 수화됨, 닫힌 삼각형; 및 pH 6.5 히스티딘 용액으로 수화됨, 닫힌 원)의 피하(SC) 주사 후 또는 제형화되지 않은 로피바카인(열린 다이아몬드)의 SC 주사 후 래트에서의 로피바카인의 혈장 농도를 나타내는 그래프이다(모든 데이터는 평균 ± 표준 편차(SD)로 표시됨);
도 2a 및 2b는 기계적 자극에 대한 마우스 발 움츠림 임계값에 대한 로피바카인 조성물(원), 로피바카인(사각형) 및 비히클(삼각형)의 SC 투여 후 효과를 도시한 일련의 그래프이다(모든 데이터는 평균 ± 평균의 표준 오차(SEM)로 표시됨); 도 2a는 시간 대 움츠림 임계값(g)의 그래픽 플롯이다; 도 2b는 시간 대 기계적 임계값의 변화(%)의 그래픽 플롯이다; 그리고
도 3a 및 3b는 동일한 투여량의 로피바카인과 비교하여 로피바카인 조성물의 단일 피내(IC) 주사 후 시간에 따른 마취 효과를 나타내는 일련의 그래프이다(모든 데이터는 평균 ± SEM로 표시됨); 도 3a는 로피바카인 조성물(닫힌 사각형) 또는 로피바카인(열린 사각형)의 IC 팽진당 3.0 mg으로 투여된 기니피그 코호트에 대한 마취 효과를 도시한다; 도 3b는 로피바카인 조성물(닫힌 삼각형) 또는 로피바카인(열린 삼각형)의 IC 팽진당 1.5 mg으로 투여된 기니피그 코호트에 대한 마취 효과를 도시한다.
