The half-life of antipyrine has been estimated from saliva samples in ten subjects by a gas chromatographic method. Half-life, apparent volume of distribution and total body clearance estimated from saliva and plasma concentrations of antipyrine are not significantly different. The concentration of antipyrine in saliva is independent of flow rate within the range expected in healthy subjects in response to mechanical and sapid stimuli. Antipyrine estimation in saliva could facilitate many areas of phaamacokinetic research limited by the difficulty of obtaining serial plasma samples.
采用气相色谱法,通过唾液样本对10名受试者的安替比林半衰期进行了估算。根据安替比林的唾液和血浆浓度估算出的半衰期、表观分布容积和全身清除率并无显著差异。在健康受试者因机械和味觉刺激而产生的预期流速范围内,唾液中安替比林的浓度与流速无关。唾液中安替比林的估算有助于解决许多受连续采集血浆样本困难所限的药代动力学研究领域的问题。
