Switching to Biphasic Insulin Aspart 30 in Patients Uncontrolled on Human Premix Insulin
Two cases relating to switching from biphasic human insulin 30 (BHI 30) to biphasic insulin aspart 30 (BIAsp 30) are described. Case 1: switching from BHI 30 to BIAsp 30 due to inadequate glycosylated haemoglobin (HbA1c) control. Case 2: switching from BHI to BIAsp 30 due to nocturnal hypoglycaemia. Case 1: HbA1cfell from 7.9 % with BHI to 6.9 % with BIAsp 30 at the six-month follow-up. Postprandial glucose (PPG) fell from 12.6 mmol/l with BHI to 9.1 mmol/l with BIAsp 30. Case 2: a man who had experienced recurrent nocturnal hypoglycaemia with neutral protamine Hagedorn (NPH) or BHI was able to maintain his glycaemic control without severe nocturnal hypoglycaemia with BIAsp 30. BIAsp 30 offers advantages over BHI 30 in terms of faster absorption, higher peak concentrations, and a more rapid and pronounced prandial glucose-lowering effect, which means that BIAsp 30 can improve PPG control and reduce the risk of nocturnal and major hypoglycaemic episodes.
