磺胺醋酰钠滴眼液的稳定剂和抑菌剂在文献中时有报道,所提及的药物也较多。笔者经过几年来的实践对其中常用的有关药物进行了实验观察并作了选择,特提出供参考。一、稳定剂硫代硫酸钠:虽能与CO_2作用避免磺胺醋酰的析出,但久贮后Na_2S_2O_3可能析出硫,使制剂产生小白点。实验证明它不能防止久贮的磺胺醋酰钠滴眼液变色。亚硫酸钠、亚硫酸氢钠:虽从理论上可防止磺胺
Sodium sulfacetamide sodium eye drops stabilizers and bacteriostatic agents have been reported in the literature, the drugs mentioned are more. The author after several years of practice on the commonly used drugs on the experimental observation and made a choice, especially for reference. First, the stabilizer sodium thiosulfate: although with the role of CO_2 to prevent the precipitation of sulfonamide, but after storage of sodium Sulfate may precipitate sulfur, the preparation of white spots. Experiments show that it can not prevent long-term storage of sulfa sodium acetate eye drops discoloration. Sodium sulfite, sodium bisulfite: Although theoretically prevent sulfonamides
