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.

The FDA has approved Xultophy 100/3.6 (Novo Nordisk), a fixed-ratio combination of insulin degludec and the GLP-1 (glucagon-like peptide-1) receptor agonist liraglutide, for once-daily treatment of adults with type 2 diabetes inadequately controlled on basal insulin (<50 units daily) or liraglutide (≤1.8 mg daily).

Nateglinide (Starlix), a new meglitinide oral glucose-lowering agent, has been approved by the FDA.

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.

The FDA has approved Juvisync (Merck), a fixed-dose combination of the antihyperglycemic DPP-4 inhibitor sitagliptin (Januvia) and the HMG-CoA reductase inhibitor simvastatin (Zocor, and others).

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.

Most experts agree that lifestyle modifications and metformin (Glucophage, and others) should be used first to treat patients with type 2 diabetes. If metformin alone fails to control hyperglycemia, there is no general agreement on which drug should be added next. A recent article in The Medical Letter offered some support for a sulfonylurea. Three recent trials published in The Lancet favored the long-acting basal insulin glargine, the glucagon-like peptide (GLP-1) analog exenatide, and the dipeptidyl peptidase-4 (DPP-4) inhibitor linagliptin, respectively. Some of the advantages...

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 .

Sitagliptin phosphate (Januvia - Merck) is the first dipeptidyl-peptidase-4 (DPP-4) inhibitor to be marketed for treatment of type 2 diabetes. It has been approved by the FDA for oral use as monotherapy or in combination with metformin (Glucophage, and others), pioglitazone (Actos) or rosiglitazone (Avandia).
