ABSTRACT: Despite exhaustive efforts to better manage patients with type 2 diabetes mellitus (formerly known as non-insulin-dependent diabetes mellitus), attempts at maintaining near normal blood glucose levels in these patients remains unsatisfactory. This continues to pose a real challenge to physicians as the prevalence of this disease in the United States continues to rise. Type 2 diabetes is defined as a syndrome characterized by insulin deficiency, insulin resistance and increased hepatic glucose output. Medications used to treat type 2 diabetes are designed to correct one or more of these metabolic abnormalities. Currently, there are five distinct classes of hypoglycemic agents available, each class displaying unique pharmacologic properties. These classes are the sulfonylureas, meglitinides, biguanides, thiazolidinediones and alpha-glucosidase inhibitors. In patients for whom diet and exercise do not provide adequate glucose control, therapy with a single oral agent can be tried. When choosing an agent, it is prudent to consider both patient- and drug-specific characteristics. If adequate blood glucose control is not attained using a single oral agent, a combination of agents with different mechanisms of action may have additive therapeutic effects and result in better glycemic control.
ABSTRACT: Epidemiologic and interventional studies have led to lower treatment targets for type 2 diabetes (formerly known as non-insulin-dependent diabetes), including a glycosylated hemoglobin level of 7 percent or less and a before-meal blood glucose level of 80 to 120 mg per dL (4.4 to 6.7 mmol per L). New oral medications make these targets easier to achieve, especially in patients with recently diagnosed diabetes. Acarbose, metformin, miglitol, pioglitazone, rosiglitazone and troglitazone help the patient's own insulin control glucose levels and allow early treatment with little risk of hypoglycemia. Two new long-acting sulfonylureas (glimepiride and extended-release glipizide) and a short-acting sulfonylurea-like agent (repaglinide) simply and reliably augment the patient's insulin supply. Combinations of agents have additive therapeutic effects and can restore glucose control when a single agent is no longer successful. Oral therapy for early type 2 diabetes can be relatively inexpensive, and evidence of its cost-effectiveness is accumulating.
