Biphasic human insulin 30 thrice daily, is it reasonable?

Abstract

Abstract Objective To evaluate the efficacy and safety of thrice daily Biphasic Human Insulin 30 (BHI 30) versus the traditional twice-daily regimen in type 2 diabetes mellitus (T2DM) patients. It’s a cross over single clinical study. Twenty-two diabetic patients who were already using BHI 30 in twice or thrice daily regimens with or without metformin were included. At the 1st interval; patients continued on their usual insulin regimen as twice or thrice daily injections with adjustment of insulin doses guided by their glucose readings. On the 2nd interval; patients were switched to the other regimen with the same total daily insulin dose redistributed. Results There was a significant decrease in HbA1c level (p < 0.05) at the end of the first 3 months of trial regardless on which regimen the patient started, but there was no significant difference in the mean HbA1c reduction in patients when they were on twice daily insulin injections (1.1 ± 1.3) versus the time they were on thrice daily insulin injections (0.8 ± 1.71), p > 0.05. On the other hand, patients had lower average blood glucose readings (mg/dl) when they were on thrice daily insulin injections (161.4 ± 62.7) compared to twice daily regimen (166.0 ± 69.5), p < 0.05.
