Abstract
Nocturnal hypoglycemia is common in the diabetic patient on twice-daily regular and intermediate (NPH or lente) insulin regimens because intermediate-acting insulins before the main evening meal produce “unopposed” free insulin peaks around 0300 h, food absorption having been completed much earlier. Fourteen insulin-dependent diabetic patients were treated for 6 wk with the alpha-glucosidase inhibitor, acarbose, in a double-blind crossover study to see whether the drug would delay absorption of the evening meal sufficiently to correct the mismatch and prevent nocturnal hypoglycemia. On 200 mg acarbose (six patients), inhibition of carbohydrate digestion was so profound as to lead to midevening hypoglycemia with severe flatulence and abdominal colic. With a smaller dose of 100 mg before the evening meal (eight patients) there was a significant reduction in MAGE and MBG coupled with a clinically significant reduction in midevening and nocturnal hypoglycemic reactions. Alpha-glucosidase inhibition therefore provides a promising new approach to the problem of nocturnal hypoglycemia although a preparation that is safe for long-term clinical use remains to be found.
