Acarbose-an aglucosidase inhibitor-is known to have a glucose lowering effect by delaying the digestion of complex carbohydrates in the small intestine. Acarbose especially prevents the abnormally high increment of postprandial blood glucose, reduces postprandial hyperinsulinemia and probably, alleviates insulin resistance. The aim of this study is to evaluate the glucose lowering effect of acarbose as an adjunt with a sulfonylurea in the treatment of NIDDM patients who have been poorly controlled with the use of sulfonylurea alone. METHODS: Forty NIDDM patients, who were poorly controlled with sulfonylurea alone, were randomly selected frorn outpatient diabetic clinic for study. For 16 weeks, they recieved either acarbose or placebo in additian to sulfonylurea under double blind method. RESULTS: 1) The metabohc parameters measured before initiation of either treatment regimen were similiar. 2) The HbAlc in placebo group increased from 8.9% to 9.0%. In contrast, in the acarbose group, HbAlc value decreased from 9.3% to 8.1%(p<0.05). 3) Mean fasting plasma glucose and 1-h postprandial glucose levels were reduced significantly in the acarbose group(p<0.001), especially in I-h postpandial glucose level in comparison with placebo group(p <0.0001). 4) Mean fasting, 1-h postprandial insulin levels decreased with time in the acarbose group in comparison with placebo group, but the decrease was not statistically significant. 5) Lipid profiles did not change during 16weeks of treatment period. 6) Adverse effects were observed in 3 patients on acarbose and 2 patients on placebo. CONCLUSION: Acarbose can be used as an effective adjuvant therapy to sulfonylurea in NIDDM patients who are poorly controlled with sulfonylurea alone.
