Abstract

Hot water extracts, KIOM-C and KIOM-MA-128, were formulated into tablets and three kinds of absorption enhancers were included in the tablets. The mixture of starch and lactose was used as an excipient, sodium carboxymethylcellulose as a disintegrating agent, and magnesium stearate as a binder. The weight ratio of water extract/excipient/disintegrating agent/absorption enhancer/binder was 80/7/10/2/1. The tablets were completely disintegrated in an aqueous_x000D_ solution in 40min, and the disintegration rates were almost the same with all the tablets tested. Among the enhancers, EDTA was the most effective in enhancing the in vitro small intestine absorption of KIOM-C and KIOM-MA-128.
