CAS:53-0 3-2
本品為17α,21-噁羥基孕甾-1,4-二烯-3,11,20-三酮。按干燥品計(jì)算,含C21H26O5應(yīng)為97.0%~102.0%。
潑尼松具有抗炎及抗過(guò)敏作用,能抑制結(jié)締組織的增生,降低毛細(xì)血管壁和細(xì)胞膜的通透性,減少炎性滲出,并能抑制組胺及其它毒性物質(zhì)的形成與釋放。本品還能促進(jìn)蛋白質(zhì)分解轉(zhuǎn)變?yōu)樘?,減少葡萄糖的利用。因而使血糖及肝糖原都增加,可出現(xiàn)糖尿,同時(shí)增加胃液分泌,增進(jìn)食欲。當(dāng)嚴(yán)重中毒性感染時(shí),與大量抗菌藥物配合使用,可有良好的降溫、抗毒、抗炎、抗休克及促進(jìn)癥狀緩解作用。其水鈉潴留及排鉀作用比可的松小,抗炎及抗過(guò)敏作用較強(qiáng),副作用較少,故比較常用。
