Ertugliflozin (trade name Steglatro) is a drug for the treatment of type 2 diabetes. In the United States, it was approved by the Food and Drug Administration for use as a monotherapy and as a fixed dose combination with either sitagliptin or with metformin.[1] In Europe, it was approved in March 2018 for use as a monotherapy or combination therapy.[2]

Ertugliflozin is a sodium/glucose cotransporter 2 (SGLT2) inhibitor and is in the class of drugs known as gliflozins.

A combination with metformin is marketed as Segluromet and a combination with sitagliptin is marketed as Steglujan.


Under the US approval, ertugliflozin is contraindicated for patients with severe kidney failure, end-stage renal disease, and dialysis.[3] The European approval does not list any contraindications apart from hypersensitivity to the drug, which is standard for all drug approvals.[2]

Adverse effects

Adverse effects in studies that were significantly more common under ertugliflozin than under placebo included mycosis of the genitals in both men and women, vaginal itch, increased urination, thirst, hypoglycaemia (low blood sugar), and weight loss under the higher dosing scheme. A rare but life-threatening side effect of gliflozins is ketoacidosis; it occurred in three patients (0.1%) in ertugliflozin studies.[3]


Up to sixfold clinical doses over two weeks, or 20-fold single doses, are tolerated by patients without any toxic effects.[2]


As with many diabetes drugs, combining ertugliflozin with insulin or insulin secretagogues (such as sulfonylureas) may result in an increased risk for low blood sugar. Combination with diuretics may result in a higher risk for dehydration and low blood pressure. No clinically relevant pharmacokinetic interactions have been found in studies.[2][3]


Mechanism of action


After oral intake, ertugliflozin is practically completely absorbed from the gut and undergoes no relevant first-pass effect. Highest blood plasma concentrations are reached after one hour. When in circulation, 93.6% of the substance are bound to plasma proteins. Ertugliflocin is metabolised mainly to glucuronides by the enzymes UGT1A9 and UGT2B7. Cytochrome P450 enzymes play only a minor role in its metabolism.[2][3]

The elimination half-life is estimated to be 17 hours. 40.9% are eliminated via the faeces (33.8% in unchanged form and 7.1% as metabolites) and 50.2% via the urine (1.5% unchanged and 48.7% as metabolites). The high proportion of unchanged substance in the faeces is probably due to hydrolysis of the metabolites back to the parent substance.[2][3]
