Abstract

The addition of phenobarbitone in therapeutic dosage to the drug regimen of prednisolone-treated subjects with rheumatoid arthritis produced measurable deterioration in the clinical status of the patients associated with a more rapid clearance of prednisolone from plasma. It is considered that phenobarbitone induced the hepatic metabolism of prednisolone, effectively reducing the steady state plasma level and resulting in clinical relapse. A slight but significant improvement in the adrenocortical response to tetracosactrin (Synacthen) was noted after phenobarbitone therapy.

摘要

对于接受泼尼松龙治疗的类风湿性关节炎患者,在其药物治疗方案中添加治疗剂量的苯巴比妥后,患者的临床状况出现了可测量的恶化,同时泼尼松龙从血浆中的清除速度加快。据认为,苯巴比妥诱导了泼尼松龙的肝脏代谢,有效降低了稳态血浆水平,导致临床复发。苯巴比妥治疗后,观察到肾上腺皮质对二十四肽促皮质素(合成促皮质素)的反应略有但显著改善。
