Polycystic ovary syndrome (PCOS), an endocrine abnormality characterized by hyperandrogenism and anovulation, affects 5-10% of women of reproductive age in the US. It is often accompanied by obesity and insulin resistance. In recent years, antidiabetic drugs, although not approved for such use by the FDA, have been tried for treatment of this disorder. This review describes the effectiveness of metformin and the thiazolidinediones in women with PCOS. Also included is a dosage and cost table for some insulin-sensitizing drugs.

Dapagliflozin (dap" a gli fl oe' zin; Farxiga – Bristol-Myers Squibb/AstraZeneca), an SGLT2 (sodium-glucose co-transporter 2) inhibitor, has been approved by the FDA for oral treatment of type 2 diabetes. Dapagliflozin is the second SGLT2 inhibitor to be approved for this indication; canagliflozin (Invokana) was the first .

Full-page newspaper advertisements addressed to patients with type 2 diabetes are promoting the convenience of "NEW once-a-day Glucophage XR (metformin HCl extended-release tablets),"and offering a coupon for a free 30-day supply in the month of March.

Empagliflozin (Jardiance – Boehringer Ingelheim/Lilly), an SGLT2 inhibitor, has been approved by the FDA for oral treatment of type 2 diabetes. It is the third SGLT2 inhibitor to be approved for this indication.

The FDA has approved the sodium-glucose co-transporter 2 (SGLT2) inhibitor ertugliflozin (Merck) for treatment of adults with type 2 diabetes, both alone (Steglatro) and in fixed-dose combinations with metformin (Segluromet) and sitagliptin (Steglujan). Ertugliflozin is the fourth SGLT2 inhibitor to be approved in the US. All four are available in combination with metformin and three are available in combination with a dipeptidyl peptidase-4 (DPP-4) inhibitor (see Table 3).

The sodium-glucose cotransporter 2 (SGLT2) inhibitor empagliflozin has been available for years alone (Jardiance – Boehringer Ingelheim) and in combination with metformin (Synjardy) to improve glycemic control in adults with type 2 diabetes. Both products have now been approved for use in children ≥10 years old. Empagliflozin is the second oral drug to become available in the US for treatment of type 2 diabetes in children; metformin has been available since 2000 for this indication. The injectable glucagon-like peptide-1 (GLP-1) receptor agonists liraglutide (Victoza) and...

Canagliflozin (kan" a gli floe' zin; Invokana – Janssen), a sodium-glucose co-transporter 2 (SGLT2) inhibitor, has been approved by the FDA for oral treatment of type 2 diabetes.

Two new injectable GLP-1 (glucagon-like peptide-1) receptor agonists, dulaglutide (Trulicity [trū li si tee] – Lilly) and albiglutide (Tanzeum [tan' zee um] – GSK), have been approved by the FDA for once-weekly treatment of type 2 diabetes. Other available GLP-1 receptor agonists include exenatide, which is approved for injection twice daily (Byetta) or once weekly (Bydureon), and liraglutide (Victoza), which is injected once daily.

Diet, exercise, and weight loss can improve glycemic control, but almost all patients with type 2 diabetes require antihyperglycemic drug therapy. Treating to a target A1C of <7% while minimizing hypoglycemia is recommended to prevent microvascular complications of diabetes (retinopathy, nephropathy, and neuropathy). An A1C target of <8% may be appropriate for some older patients.

The FDA has approved lixisenatide (Sanofi), a short-acting injectable GLP-1 (glucagon-like peptide-1) receptor agonist, for once-daily treatment of adults with type 2 diabetes, both alone (Adlyxin) and in a fixed-ratio combination with insulin glargine (Soliqua 100/33). Lixisenatide has been available since 2013 in many other countries as Lyxumia. It is the fifth GLP-1 receptor agonist to be approved in the US.
