1 Three intra-articular prednisolone analogues have been studied in a group of forty-six rheumatoid arthritic subjects. Each compound was tested at 50 mg and 100 mg dose over 3 weeks. 2 The anti-inflammatory effect was assessed by quantitative thermography. Systemic escape of the drug was monitored by plasma prednisolone and cortisol levels. 3 Both the systemic escape from the joint and the duration of effect on injected and uninjected knees were related to drug solubility. 4 Depression of plasma cortisol occurred with all three preparations and was most prolonged with the long-acting preparation. 5 Increasing the dose from 50 mg to 100 mg increased the antiflammatory effect only with the soluble acetate preparation.
1 在一组46名类风湿性关节炎患者中对三种关节内注射用泼尼松龙类似物进行了研究。每种化合物均以50毫克和100毫克的剂量进行了为期3周的测试。2 通过定量热成像评估抗炎效果。通过血浆泼尼松龙和皮质醇水平监测药物的全身逃逸情况。3 药物从关节的全身逃逸以及对注射和未注射膝关节的作用持续时间均与药物溶解度有关。4 所有三种制剂均导致血浆皮质醇降低,长效制剂导致的降低最为持久。5 仅可溶性醋酸盐制剂将剂量从50毫克增加到100毫克时抗炎效果增强。
