氨甲苯酸(Acidum Aminomethylbenzoicum)是临床上常用的止血药。因治疗需要,经常与其它药物配伍使用。氨甲苯酸在水中溶解度小,因分子结构中含氨基和羧基,为两性化合物,在酸或碱水中均可成盐而溶解。文献报道注射液pH值以3.8～4.2为宜。临床静脉滴注过程中,往往因和其它药物配伍使用,引起输液pH值改变,致使药物沉淀,或发生药物相互作用而分解失效。因此有必要结合临床对氨甲苯酸与呋喃苯胺酸等 Acidum Aminomethylbenzoicum is a clinically used hemostatic agent. Due to treatment needs, often with other drugs compatibility. Trimellitic acid solubility in water is small, because of the molecular structure containing amino and carboxyl, amphoteric compounds, in acid or alkali water can be salified and dissolved. Reported in the literature pH 3.8 to 4.2 is appropriate. Clinical intravenous infusion process, often due to compatibility with other drugs to use, causing the infusion of pH changes, resulting in drug precipitation, or the occurrence of drug interactions and decomposition failure. Therefore it is necessary to combine the clinical ammonia and furosemide acid and so on
