조혈제에 관한 연구 II 특효성 조혈제 제조에 관한 연구

Studies on the Ferruginous Hematinics II A Study on Preparation of Sustained-Release Formed Ferruginous Hematinics.

Sustained-release dosage form of ferruginous hematinics which can be absorbed effectively without forming "iron block" that caused by high concentration of Iron in the gastrointestinal tract, was studied. Gelatinized micropellets containing medicament were prepared according to the method of N. Tanaka et al. and hardened in 10% formalin-isopropanol in various time. Gelatinized micropellets were digested with artificial gastric juice and prepared a graph of iron concentration determined by Hong's method. As a result, it is assumed that gelatinized sustained-release dosage form can be a good ferruginous hematinics and it is shown that the preparation of 72-hour-hardening in 10% formalin-isopropanol has a suitable sustained release.d release.
