氟芬那酸是一种常用的非激素类消炎镇痛药物,又称为氟灭酸。常温下为淡黄色或淡黄绿色的结晶性粉末,味苦,几乎不溶于水但易溶于乙醇。其药理作用类似于氯丙酸,具有显著的消炎、镇痛和解热作用,比氨基比林、阿司匹林、保泰松等药物更强效,而镇痛效果较差,不良反应较小。临床上主要用于治疗风湿性关节炎和类风湿性关节炎,对后者的效果相对较差。偶见胃肠道不适、腹泻、皮疹、蛋白尿、血尿及浮肿等不良反应,哮喘病畜慎用。
背景与概述氟灭酸同样为淡黄色或淡黄绿色的结晶性粉末,味苦,几乎不溶于水但能溶于50%乙醇中。作为非激素类消炎镇痛药,其熔点为132~136℃。它由间溴代三氟甲苯与邻氨基苯甲酸通过缩合反应制得。氟灭酸是一种非甾体抗炎镇痛药,对风湿性疾病和急性湿热症状有显著疗效,能够减轻关节肿胀并具有明显的抗炎、止痛作用。其解热镇痛效力是阿司匹林的三倍,并且与保泰松及肾上腺皮质激素类似,也有解热作用。
氟灭酸还可合成多种衍生物,如氟灭酸丁酯、甲酯、乙酯、依托芬那酯、烟氟灭酸和莫尼氟酯等。它还能通过还原、环合或缩合反应生成一系列安定、镇痛及抗精神病药物,例如三氟丙嗪、三氟拉嗪和氟奋乃静等。由于其消炎止痛作用及其在有机合成中的重要作用,学者们对其合成方法和分析方法进行了大量研究。
合成路线解热消炎作用强于氨基比林、阿司匹林和保泰松,镇痛效果较差,但不良反应较小,适用于类风湿性关节炎和风湿性关节炎等疾病的治疗。
规格与用法用量可能出现胃部不适、腹泻、皮疹、蛋白尿、血尿和浮肿等不良反应。使用时需谨慎,并注意观察动物的反应情况。
