抗坏血酸口服后在人体内的吸收速度与程度,可能受到不同剂型、剂量及胃肠道生理条件的影响。本文研究了几种抗坏血酸剂型经口服后在人体内的吸收情况。方法 4名健康成人受试者在检测尿药浓度前,每人日服抗坏血酸1g,至少持续二周,使体内抗坏血酸的贮存量呈饱和状态。实验前两日停药。 The rate and extent of ascorbate absorption in humans after oral administration may be affected by different dosage forms, dosages, and gastrointestinal physiological conditions. This article studies the absorption of several ascorbic acid dosage forms in humans after oral administration. Methods Four healthy adult subjects tested 1g of ascorbic acid per day for at least two weeks before testing for urinary drug concentration, allowing the body to store ascorbate in a saturated state. Two days before the experiment withdrawal.
