The tablet was taken only once 30 minutes before breakfast. Symptoms monitoring, physical examination and laboratory test were carried out and followed up for 2 weeks. The results revealed that subjects had no abnormal detected and no hypoglycemia as well as normal blood chemistry.

      Clinical trial phase II was conducted in 30-type 2 diabetics (Inclusion criteria: fasting plasma glucose (FPG) 150-250 mg/dl, HbA1C 7.5-9%, and no severity complication) divided into 2 phases; run-in phase for evaluated compliance of MC and trial phase. In run-in phase, placebo was administered once daily 30-minutes before breakfast for 4 weeks. Then, in trial phase, the MC-900 mg-capsule was administered once daily 30- minutes before breakfast for 12 weeks.
