Eltero15 mg

Eltero is a sodium-glucose cotransporter-2 (SGLT2) inhibitor used in the management of type 2 diabetes mellitus.

Established / FDA-approved indication

• As an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.

Combination use

Eltero may be used alone or in combination with other antidiabetic agents such as metformin, sulfonylureas, DPP-4 inhibitors, or insulin, when glycemic control is not achieved with a single agent, under physician supervision.

Not indicated for

• Type 1 diabetes mellitus
• Treatment of diabetic ketoacidosis

Cardiovascular outcomes

In a large cardiovascular outcomes trial, Eltero showed cardiovascular safety (non-inferiority for major adverse cardiovascular events) in patients with type 2 diabetes and established atherosclerotic cardiovascular disease, but a cardiovascular risk-reduction benefit has not been established; Eltero is therefore not indicated specifically for cardiovascular risk reduction.

Off-label use: Eltero is not commonly prescribed off-label. Any use outside the above should be individualized by a physician.

Each film-coated tablet contains Ertugliflozin (as ertugliflozin L-pyroglutamic acid) equivalent to 5 mg or 15 mg of Ertugliflozin as the active ingredient, together with pharmaceutically acceptable excipients.

Eltero is an oral, selective inhibitor of sodium-glucose cotransporter-2 (SGLT2), a protein responsible for the majority of glucose reabsorption in the kidney. By blocking this transporter, Eltero lowers blood glucose levels through an insulin-independent mechanism. It is used as part of a comprehensive treatment plan that includes diet, exercise, and glucose monitoring in adults with type 2 diabetes mellitus.

Sodium-Glucose Cotransporter-2 (SGLT2) Inhibitor; oral antihyperglycemic (antidiabetic) agent. Eltero belongs to this class of medicines.

Ertugliflozin selectively and reversibly inhibits SGLT2, the transporter responsible for reabsorbing the majority of glucose filtered by the kidney's proximal renal tubules.

Mechanism

• Inhibition of SGLT2 reduces renal reabsorption of filtered glucose and lowers the renal threshold for glucose, increasing urinary glucose excretion.
• This action is independent of insulin secretion or insulin action, so Ertugliflozin can be used at any stage of beta-cell function.
• The glucose-lowering effect also produces a mild osmotic diuresis and modest reductions in body weight and blood pressure.

Pharmacokinetics

Ertugliflozin is rapidly absorbed after oral administration, is highly bound to plasma proteins, undergoes hepatic metabolism primarily via glucuronidation (UGT1A9 and UGT2B7), and is eliminated mainly in feces and urine. Its elimination half-life supports once-daily dosing.

Eltero is taken orally, once daily in the morning, with or without food. Tablets should be swallowed whole and not crushed or chewed.

Insulin and insulin secretagogues

Concomitant use of Eltero with insulin or insulin secretagogues (e.g., sulfonylureas) increases the risk of hypoglycemia. A lower dose of the insulin or secretagogue may be required.

Diuretics

Eltero causes an osmotic diuresis, which may add to the effect of loop or thiazide diuretics and increase the risk of volume depletion, dehydration, and hypotension, particularly in the elderly and in patients with renal impairment.

UGT enzyme inducers

Strong inducers of UDP-glucuronosyltransferase (UGT) enzymes, such as rifampin, may reduce the exposure and glucose-lowering efficacy of Eltero; consider monitoring glycemic control if co-administered.

Digoxin

A modest increase in digoxin exposure has been observed with concomitant Eltero use; patients on digoxin should be monitored appropriately.

Common side effects

• Genital mycotic (yeast) infections
• Urinary tract infections
• Headache
• Vaginal pruritus
• Increased urination
• Mild increase in LDL cholesterol

Serious side effects (seek prompt medical attention)

• Euglycemic diabetic ketoacidosis — can occur even with normal or near-normal blood glucose; symptoms include nausea, vomiting, abdominal pain, fatigue, and difficulty breathing.
• Necrotizing fasciitis of the perineum (Fournier's gangrene) — a rare but life-threatening infection; seek emergency care for perineal/genital pain, swelling, redness, or fever.
• Lower limb amputation risk associated with the SGLT2 inhibitor class (see Precautions and Warnings).
• Volume depletion, dehydration, and hypotension.
• Hypersensitivity reactions.
• Urosepsis and pyelonephritis.

Pregnancy: Eltero is not recommended during pregnancy, particularly in the second and third trimesters, as SGLT2 inhibitors are believed to affect fetal renal development based on animal data and mechanism of action. Eltero should be used only if clearly needed and if the potential benefit justifies the potential risk to the fetus; a physician should be consulted before use in pregnancy, and an alternative antidiabetic regimen should generally be considered if pregnancy is planned or confirmed.

Lactation: It is not known whether Eltero is present in human milk. Because of the potential for adverse effects on renal development in the nursing infant, Eltero is not recommended while breastfeeding; a physician should be consulted to weigh the benefits of breastfeeding against the theoretical risk.

Diabetic ketoacidosis

Eltero has been associated with cases of euglycemic diabetic ketoacidosis, sometimes fatal, in which blood glucose may be only mildly elevated. Maintain a high index of suspicion in patients presenting with nausea, vomiting, abdominal pain, malaise, or dyspnea, even if glucose levels appear near-normal. Discontinue Eltero promptly if ketoacidosis is suspected or confirmed.

Lower limb amputation

An increased risk of lower limb amputation has been observed with SGLT2 inhibitors as a class (most strongly established for canagliflozin, but caution is advised with Eltero). Monitor patients, particularly those with a history of amputation, peripheral vascular disease, neuropathy, or diabetic foot ulcers, for signs of infection, new pain, or tenderness in the lower limbs.

Necrotizing fasciitis of the perineum (Fournier's gangrene)

Rare but serious and life-threatening cases have been reported across the SGLT2 inhibitor class, including with Eltero. Advise patients to seek immediate medical attention for severe pain, tenderness, erythema, or swelling in the genital or perineal area, with or without fever or malaise. Discontinue Eltero if this condition is suspected.

Volume depletion

Eltero can cause intravascular volume contraction. Symptomatic hypotension may occur, particularly in the elderly, in patients with renal impairment, low systolic blood pressure, or those on diuretics or other antihypertensives. Assess and correct volume status before initiating Eltero.

Genital mycotic infections and urinary tract infections

Increased risk of genital mycotic infections and urinary tract infections, including serious cases such as urosepsis and pyelonephritis, has been reported.

Hypoglycemia

Risk of hypoglycemia is increased when Eltero is combined with insulin or insulin secretagogues (see Interactions).

Surgery and prolonged fasting

Consider temporarily discontinuing Eltero before scheduled major surgery or in situations of prolonged fasting or acute serious illness, due to the risk of ketoacidosis; resume once the patient's condition has stabilized.

Hypersensitivity

Serious hypersensitivity reactions, including anaphylaxis and angioedema, have been reported; discontinue Eltero and institute appropriate treatment if such a reaction occurs.

There is limited clinical experience with Eltero overdose. In the event of a suspected overdose, seek immediate medical attention or contact emergency services or a poison control center. Management should include general supportive measures, close monitoring of clinical status, blood glucose, electrolytes, renal function, and volume status, as clinically indicated. There is no specific antidote for Eltero.

Store at room temperature (below 30°C), away from light and moisture. Keep out of reach of children.

Renal impairment

Eltero is not recommended in patients with an eGFR persistently below 45 mL/min/1.73m² and is contraindicated in severe renal impairment, end-stage renal disease, or dialysis (see Contraindications).

Hepatic impairment

No dosage adjustment is needed in mild-to-moderate hepatic impairment; use in severe hepatic impairment has not been studied and is not recommended.

Elderly patients

Elderly patients, especially those aged 65 years and older, are at greater risk of volume depletion; monitor renal function and volume status closely.

Pediatric patients

Safety and efficacy of Eltero in patients under 18 years of age have not been established; use in this population is not recommended.

Pregnancy and lactation

See Pregnancy and Lactation section above.

Eltero is generally used long-term as part of chronic management of type 2 diabetes mellitus. Duration of treatment should be individualized by the treating physician based on glycemic response, tolerability, and periodic reassessment of renal function and overall diabetes control.

SGLT2 inhibitors (Sodium-Glucose Cotransporter-2 inhibitors); oral antidiabetic agents

Ertugliflozin works by selectively inhibiting SGLT2 in the proximal renal tubule, the transporter responsible for reabsorbing most of the glucose filtered by the kidney. Blocking SGLT2 reduces glucose reabsorption and lowers the renal glucose threshold, leading to increased urinary excretion of glucose and a corresponding reduction in plasma glucose levels. This glucose-lowering effect is independent of insulin secretion or insulin sensitivity.

Safety and efficacy of Eltero have not been established in pediatric patients under 18 years of age. Eltero is therefore not recommended for use in children and adolescents until further data become available.
