Use Of Insulin Detemir Research Articles

The usage of a simplified self‐titration dosing guideline (303 Algorithm) for insulin detemir in patients with type 2 diabetes – results of the randomized, controlled PREDICTIVE™ 303 study

The Predictable Results and Experience in Diabetes through Intensification and Control to Target: An International Variability Evaluation 303 (PREDICTIVE 303) Study (n = 5604) evaluated the effectiveness of insulin detemir, a long-acting basal insulin analogue, using a simplified patient self-adjusted dosing algorithm (303 Algorithm group) compared with standard-of-care physician-driven adjustments (Standard-of-care group) in a predominantly primary care setting, over a period of 6 months. Insulin detemir was to be started once-daily as add-on therapy to any other glucose-lowering regimens or as a replacement of prestudy basal insulin in patients with type 2 diabetes. Investigator sites rather than individual patients were randomized to either the 303 Algorithm group or the Standard-of-care group. Patients from the 303 Algorithm group sites were instructed to adjust their insulin detemir dose every 3 days based on the mean of three 'adjusted' fasting plasma glucose (aFPG) values (capillary blood glucose calibrated to equivalent plasma glucose values) using a simple algorithm: mean aFPG < 80 mg/dl (<4.4 mmol/l), reduce dose by 3 U; aFPG between 80 and 110 mg/dl (4.4-6.1 mmol/l), no change; and aFPG > 110 mg/dl (>1.1 mmol/l), increase dose by 3 U. The insulin detemir dose for patients in the Standard-of-care group was adjusted by the investigator according to the standard of care. Mean A1C decreased from 8.5% at baseline to 7.9% at 26 weeks for the 303 Algorithm group and from 8.5 to 8.0% for the Standard-of-care group (p = 0.0106 for difference in A1C reduction between the two groups). Mean FPG values decreased from 175 mg/dl (9.7 mmol/l) at baseline to 141 mg/dl (7.8 mmol/l) for the 303 Algorithm group and decreased from 174 mg/dl (9.7 mmol/l) to 152 mg/dl (8.4 mmol/l) for the Standard-of-care group (p < 0.0001 for difference in FPG reduction between the two groups). Mean body weight remained the same at 26 weeks in both groups (change from baseline 0.1 and -0.2 kg for the 303 Algorithm group and the Standard-of-care group respectively). At 26 weeks, 91% of the patients in the 303 Algorithm group and 85% of the patients in the Standard-of-care group remained on once-daily insulin detemir administration. The rates of overall hypoglycaemia (events/patient/year) decreased significantly from baseline in both groups [from 9.05 to 6.44 for the 303 Algorithm group (p = 0.0039) and from 9.53 to 4.95 for the Standard-of-care group (p < 0.0001)]. Major hypoglycaemic events were rare in both groups (0.26 events/patient/year for the 303 Algorithm group and 0.20 events/patient/year for the Standard-of-care group; p = 0.2395). In conclusion, patients in the 303 Algorithm group achieved comparable glycaemic control with higher rate of hypoglycaemia as compared with patients in the Standard-of-care group, possibly because of more aggressive insulin dose adjustments. The vast majority of the patients in both groups were effectively treated with once-daily insulin detemir therapy. The use of insulin detemir in this predominantly primary care setting achieved significant improvements in glycaemic control with minimal risk of hypoglycaemia and no weight gain.

Insulin detemir: A new option for the treatment of diabetes

To highlight the pharmacology, clinical data, and practical application for the use of insulin detemir, a new long-acting insulin analog in the treatment of type 2 diabetes. Published clinical, pharmacokinetic, and pharmacodynamic studies of insulin detemir, as well as contemporary studies and reviews about the management of patients with type 2 diabetes. Insulin therapy, if titrated appropriately, is the most physiological and effective intervention for lowering blood glucose and may help preserve beta-cell function in patients with type 2 diabetes. Insulin detemir, in comparative clinical trials, has been shown to provide effective glycemic control and a consistent blood glucose-lowering response for up to 24 h, a decreased incidence of nocturnal hypoglycemia, and less weight gain than other basal insulin formulations. Insulin therapy is often met with resistance from both patients and healthcare providers because of concerns about its effectiveness, hypoglycemia, injections, and weight gain. Insulin detemir, designed to closely mimic basal insulin secretion, may help overcome some of the barriers to effective diabetes management, i.e., hypoglycemia and weight gain, and lead to better outcomes.

Insulin Detemir and Basal Insulin Therapy

With the introduction of insulin detemir (Levemir ® [Novo Nordisk A/S, Bagsvaerd, Denmark]), a long-acting basal insulin analog, it is an opportune moment to reevaluate the use of basal insulin therapy and consider current treatment strategies, including the use of insulin detemir. This review examines the need for effective treatment options for diabetes and the economic burden of this disease. The importance of achieving glycemic control targets and the role of basal insulin therapy are discussed. Finally, the use of insulin detemir is briefly reviewed with a look at its clinical pharmacology, its use in basal insulin therapy, and its cost-effectiveness.

Insulin detemir in the treatment of type 1 and type 2 diabetes

Insulin detemir is a soluble long-acting human insulin analogue at neutral pH with a unique mechanism of action. Following subcutaneous injection, insulin detemir binds to albumin via fatty acid chain, thereby providing slow absorption and a prolonged metabolic effect. Insulin detemir has a less variable pharmacokinetic profile than insulin suspension isophane or insulin ultralente. The use of insulin detemir can reduce the risk of hypoglycemia (especially nocturnal hypoglycemia) in type 1 and type 2 diabetic patients. However, overall glycemic control, as assessed by glycated hemoglobin, is only marginally and not significantly improved compared with usual insulin therapy. The weight gain commonly associated with insulin therapy is rather limited when insulin detemir is used. In our experience, this new insulin analogue is preferably administrated at bedtime but can be proposed twice a day (in the morning and either before the dinner or at bedtime). Detemir is a promising option for basal insulin therapy in type 1 or type 2 diabetic patients.

Insulin detemir: a new basal insulin analogue

Basal insulin therapy is an integral part of the intensive management of type 1 diabetes and it is also often used in type 2 diabetes. An ideal insulin regimen in patients with diabetes would mirror the 24-h insulin profile of a non-diabetic person, thereby preventing hyperglycaemia without inducing hypoglycaemia. Until recently, available insulins have pharmacokinetic disadvantages, compared to physiological insulin secretion. Insulin detemir is a new basal insulin analogue recently available for commercial use in the UK. Clinical trials have demonstrated lower fasting plasma glucose levels, lower variability in plasma glucose, predictable action profile and a reduced risk of nocturnal hypoglycaemia and weight gain, compared to conventional basal insulins. This study reviews the properties and potential use of insulin detemir.
