Weight Effect of Current and Experimental Drugs for Diabetes Mellitus

From Promotion to Alleviation of Obesity
Review Article


Two landmark intervention studies, the Diabetes Control and Complications Trial (DCCT) in patients with type 1 diabetes mellitus and the United Kingdom Prospective Diabetes Study (UKPDS) in patients with type 2 diabetes mellitus, have unequivocally demonstrated that intensive diabetes therapy reduces the risk of long-term diabetic complications. As a result, the commonly accepted treatment goal for most patients with diabetes is the achievement and maintenance of glycemic control that is as close to the normal range as safely possible. Important adverse effects of intensive diabetes therapy, particularly when the treatment includes insulin or several of the oral antihyperglycemic agents, are an increased risk of hypoglycemia and undesired weight gain.

Improvement of glycemic control with insulin, insulin secretagogues (sulfonylureas, meglitinides), and insulin sensitizers (thiazolidinediones) is often accompanied by weight gain. The etiology of this weight gain is likely multifaceted, including a reduction of glucosuria, increased caloric intake to prevent hypoglycemia, and anabolic effects on adipose tissue.

Biguanides and α-glucosidase inhibitors have a neutral or even positive effect (decrease) on weight, which may partly be attributable to their non-insulinotropic mechanism of action, a modest effect on satiety, and to their gastrointestinal adverse effect profile.

Several antihyperglycemic agents that are currently in clinical development may improve glycemie control in conjunction with weight reduction. These include an analog of the pancreatic β-cell hormone amylin (pramlintide), as well as glucagon-like peptide-1 (GLP-1) and exendin, and their analogs.

Pharmacological agents with antihyperglycemic and positive weight effects have the potential to become important additions to our therapeutic armamentarium, in that they may help to achieve glycemie targets while addressing the long-standing clinical problem of weight gain as an adverse effect of intensive diabetes therapy.
