BackgroundAcarbose and repaglinide are two safe and effective antidiabetic agents that are especially in wide use in Asian and Middle Eastern countries. These two prandial agents share some outstanding qualities that their newer counterparts do not. While globally available in generic versions, both are oral and cheap. There is a paucity of data regarding their comparative efficacy. Herein, a head-to-head comparison of the efficacy of the two in treatment of postprandial hyperglycemia of newly-diagnosed type 2 diabetes was investigated.Materials And MethodsOne hundred and sixty-four newly-diagnosed type 2 diabetes patients with fasting plasma glucose levels of <7.2 mmol/L (130 mg/dL) but 2-hour postprandial glucose (2hPPG) levels of >10 mmol/L (180 mg/dL) were consecutively alternated between acarbose- and repaglinide-treatment for 6 months.ResultsPer protocol analysis, 67% of acarbose-treated patients versus 85% of repaglinide-treated patients achieved 2hPPG levels of <10 mmol/L (180 mg/dL) (P = 0.05). Treatment adherence rates were 52.4% and 72%, respectively (P < 0.02). Thirteen of the repaglinide-treated and 2 of acarbose-treated patients reported at least one episode of hypoglycemia (P < 0.03). Fasting plasma glucose, 2hPPG, glycated hemoglobin and basal insulin requirement decreased more significantly with repaglinde than acarbose (P, <0.05, <0.04, <0.04 and <0.03, respectively). Weight increased with repaglinide and decreased with acarbose (P = 0.03). There were no significant changes in LDL levels with either treatment (P = 0.58), but triglycerides decreased more significantly with acarbose treatment (P = 0.03) CONCLUSIONS: Significantly higher rates of treatment-adherence and at-target glycemic levels were seen with repaglinide treatment. Weight decreased with acarbose and increased with repaglinide treatment. Hypoglycemic episodes were much less frequent with acarbose treatment.Copyright © 2020 Southern Society for Clinical Investigation. Published by Elsevier Inc. All rights reserved.
