The oral glucagon-like peptide-1 (GLP-1) receptor agonist semaglutide (Rybelsus – Novo Nordisk), which was approved by the FDA in 2019 for treatment of type 2 diabetes in adults, has now also been approved to reduce the risk of major adverse cardiovascular events (MACE) in adults with type 2 diabetes who are at high risk for these events. The injectable GLP-1 receptor agonists semaglutide (Ozempic), dulaglutide (Trulicity), and liraglutide (Victoza) are also approved for cardiovascular risk reduction in patients with type 2 diabetes (see Table 1).

Bexagliflozin (Brenzavvy – TheracosBio), a sodium-glucose cotransporter 2 (SGLT2) inhibitor, has been approved by the FDA to improve glycemic control in adults with type 2 diabetes. It is the fifth SGLT2 inhibitor to be approved in the US for this indication (see Table 4).

The recent report of a reduction in cardiovascular mortality in patients with type 2 diabetes treated with the SGLT2 inhibitor empagliflozin (Jardiance) was published soon after the FDA issued new warnings about an increased risk of fractures with canagliflozin (Invokana).

Sitagliptin (Januvia) and metformin (Glucophage, and others) are now available in a single tablet (Janumet - Merck) for treatment of type 2 diabetes. The combination is approved by the FDA for use in patients not adequately controlled by sitagliptin or meformin alone or in those already taking both drugs. Metformin is also available in combination with the thiazolidinediones pioglitazone and rosiglitazone and with the sulfonylureas glipizide and glyburide.

The FDA has approved orforglipron (Foundayo – Lilly), an oral small-molecule, nonpeptide glucagon-like peptide-1 (GLP-1) receptor agonist, to reduce excess body weight and maintain weight reduction long term in adults with obesity, or with overweight and at least one weight-related comorbidity. Orforglipron is the second oral GLP-1 receptor agonist to be approved in the US for this indication; an oral formulation of the peptide semaglutide (Wegovy) was approved in 2025.

Most patients with diabetes mellitus now test their own blood glucose. In recent years, meters commercially available for self-testing have become smaller and easier to use.

Sermorelin acetate, a synthetic form of human growth-hormone-releasing factor has been approved by the FDA for treatment of idiopathic growth hormone deficiency in children with growth failure.

An automatic, noninvasive, glucose-monitoring device (GlucoWatch Biographer) has been approved for marketing by the FDA. The manufacturer states that it is not meant to replace a regular blood glucose meter.

The FDA has approved fixed-dose combinations of metformin with either canagliflozin (Invokamet) or dapagliflozin (Xigduo XR) for treatment of patients with type 2 diabetes not adequately controlled with any one of these drugs, or in those already being treated with both metformin and either canagliflozin or dapagliflozin.

The FDA has approved a new formulation of glucagon (Gvoke – Xeris) for subcutaneous treatment of severe hypoglycemia in patients ≥2 years old with diabetes. Conscious patients with symptoms of hypoglycemia can take oral glucose. Glucagon is usually administered by a caregiver to an unresponsive patient. The new formulation is available in a single-use prefilled syringe (Gvoke PFS) and is expected to become available in a single-use auto-injector (Gvoke HypoPen) in 2020. Unlike previously available injectable glucagon products (Glucagon Emergency Kit, and others), Gvoke does not...
