Abstract

Twice-daily NPH monotherapy is commonly prescribed in type 2 diabetes, but it lacks short-or rapid-acting insulin to address postprandial blood glucose (pp BG). Humalog® Mix25 (Mix25) provides both intermediate-and rapid-acting insulin and may offer a therapeutic advantage. In an open-label crossover study, 66 patients with type 2 diabetes were randomly assigned to twice-daily Mix25 or NPH for 3 months, followed by the alternate treatment for 3 months. Primary outcomes were 7-point self-monitored BG profiles, HbA1c, hypoglycaemic rate, and insulin doses. Two-hour pp BG excursions and absolute BG values 2 hours after breakfast and dinner, before lunch, and at 3 am were found to be significantly lower during Mix25 treatment; the fasting BG level was significantly higher. Mean HbA1c was also significantly lower after Mix25 therapy (8.36% versus 8.59%; P=0.043). Hypoglycaemia and total daily insulin dose were not significantly different between treatments. In conclusion, compared with twice-daily NPH, twice-daily Mix25 at similar doses resulted in lower BG excursions after breakfast and dinner, lower BG concentrations at 4 of 7 points on the BG profile, a lower HbA1c, and no increase in hypoglycaemia. Mix25 may be a desirable alternative to NPH for type 2 diabetic patients using twice-daily insulin therapy.
