Treatment of type 2 diabetes mellitus.

摘要

Type 2 diabetes mellitus (formerly called non-insulin-dependent diabetes) causes abnormal carbohydrate, lipid and protein metabolism associated with insulin resistance and impaired insulin secretion. Insulin resistance is a major contributor to progression of the disease and to complications of diabetes. Type 2 diabetes is a common and underdiagnosed condition that poses treatment challenges to family practitioners. The introduction of new oral agents within the past three years has expanded the range of possible combination regimens available for treating type 2 diabetes. Despite the choice of pharmacologic agents, physicians must stress the nonpharmacologic approaches of diet modification, weight control and regular exercise. Pharmacologic approaches must be based on patient characteristics, level of glucose control and cost considerations. Combinations of different oral agents may be useful for controlling hyperglycemia before insulin therapy becomes necessary. A stepped-care approach to drug therapy may provide the most rational, cost-efficient approach to management of this disease. Pharmaco-economic analyses of clinical trials are needed to determine cost-effective treatment strategies for management of type 2 diabetes.
