Available dosage forms: TABLET.
Routes of administration: ORAL.
Brand Names
- ERTUGLIFLOZIN
- SEGLUROMET
- STEGLATRO
- STEGLUJAN
Indications and Usage
STEGLUJAN® is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. Limitations of Use Not recommended for use to improve glycemic control in patients with type 1 diabetes mellitus [see Warnings and Precautions (5.1)]. Has not been studied in patients with a history of pancreatitis. It is unknown whether patients with a history of pancreatitis are at increased risk for the development of pancreatitis while using STEGLUJAN [see Warnings and Precautions (5.2)].
Contraindications
STEGLUJAN is contraindicated in patients with: Severe renal impairment (eGFR less than 30 mL/min/1.73 m2), end-stage renal disease (ESRD), or on dialysis [see Warnings and Precautions (5.4) and Use in Specific Populations (8.6)]. Hypersensitivity to sitagliptin, ertugliflozin, or any excipient, in STEGLUJAN. Reactions such as anaphylaxis or angioedema have occurred [see Warnings and Precautions (5.9) and Adverse Reactions (6.2)].
Adverse Reactions
The following important adverse reactions are described elsewhere in the labeling: Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis [see Warnings and Precautions (5.1)] Pancreatitis [see Warnings and Precautions (5.2)] Lower Limb Amputation [see Warnings and Precautions (5.3)] Acute Renal Failure [see Warnings and Precautions (5.4)] Volume Depletion [see Warnings and Precautions (5.5)] Genitourinary Infections, including Urosepsis, Pyelonephritis, Necrotizing Fasciitis of the Perineum (Fournier’s Gangrene), and Genital Mycotic Infections [see Warnings and Precautions (5.6)] Heart Failure [see Warnings and Precautions (5.7)] Hypoglycemia with Concomitant Use with Insulin or Insulin Secretagogues [see Warnings and Precautions (5.8)] Hypersensitivity Reactions [see Warnings and Precautions (5.9)] Severe and Disabling Arthralgia [see Warnings and Precautions (5.10)] Bullous Pemphigoid [see Warnings and Precautions (5.11)]
Drug Interactions
Table 3: Clinically Significant Drug Interactions with STEGLUJAN Insulin or Insulin Secretagogues Clinical Impact: The risk of hypoglycemia is increased when STEGLUJAN is used in combination with insulin or an insulin secretagogue. Intervention: A lower dose of insulin or insulin secretagogue may be required to minimize the risk of hypoglycemia when used in combination with STEGLUJAN. Lithium Clinical Impact: Concomitant use of an SGLT2 inhibitor with lithium may decrease serum lithium concentrations. Intervention: Monitor serum lithium concentration more frequently during STEGLUJAN initiation and dosage changes. Positive Urine Glucose Test Clinical Impact: SGLT2 inhibitors increase urinary glucose excretion and will lead to positive urine glucose tests. Intervention: Monitoring glycemic control with urine glucose tests is not recommended in patients taking SGLT2 inhibitors. Use alternative methods to monitor glycemic control. Interference with 1,5-anhydroglucitol (1,5-AG) Assay Clinical Impact: Measurements of 1,5-AG are unreliable in assessing glycemic control in patients taking SGLT2 inhibitors. Intervention: Monitoring glycemic control with 1,5-AG assay is not recommended. Use alternative methods to monitor glycemic control.
Mechanism of Action
STEGLUJAN STEGLUJAN combines two antihyperglycemic agents with complementary mechanisms of action to improve glycemic control in patients with type 2 diabetes mellitus: ertugliflozin, a SGLT2 inhibitor, and sitagliptin, a DPP-4 inhibitor. Ertugliflozin SGLT2 is the predominant transporter responsible for reabsorption of glucose from the glomerular filtrate back into the circulation. Ertugliflozin is an inhibitor of SGLT2. By inhibiting SGLT2, ertugliflozin reduces renal reabsorption of filtered glucose and lowers the renal threshold for glucose, and thereby increases urinary glucose excretion. Sitagliptin Sitagliptin is a DPP-4 inhibitor, which is believed to exert its actions in patients with type 2 diabetes mellitus by slowing the inactivation of incretin hormones. Concentrations of the active intact hormones are increased by sitagliptin, thereby increasing and prolonging the action of these hormones. Incretin hormones, including glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), are released by the intestine throughout the day, and levels are increased in response to a meal. These hormones are rapidly inactivated by the enzyme, DPP-4. The incretins are part of an endogenous system involved in the physiologic regulation of glucose homeostasis. When blood glucose concentrations are normal or elevated, GLP-1 and GIP increase insulin synthesis and release from pancreatic beta cells by intracellular signaling pathways involving cyclic AMP. GLP-1 also lowers glucagon secretion from pancreatic alpha cells, leading to reduced hepatic glucose production. By increasing and prolonging active incretin levels, sitagliptin increases insulin release and decreases glucagon levels in the circulation in a glucose-dependent manner. Sitagliptin demonstrates selectivity for DPP-4 and does not inhibit DPP-8 or DPP-9 activity in vitro at concentrations approximating those from therapeutic doses.
Overdosage
STEGLUJAN In the event of an overdose with STEGLUJAN, contact the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdosage management recommendations. Employ the usual supportive measures as dictated by the patient’s clinical status. Ertugliflozin Removal of ertugliflozin by hemodialysis has not been studied. Sitagliptin In the event of an overdose, it is reasonable to employ the usual supportive measures, e.g., remove unabsorbed material from the gastrointestinal tract, employ clinical monitoring (including obtaining an electrocardiogram), and institute supportive therapy as dictated by the patient’s clinical status. Sitagliptin is modestly dialyzable. In clinical studies, approximately 13.5% of the dose was removed over a 3- to 4-hour hemodialysis session. Prolonged hemodialysis may be considered if clinically appropriate. It is not known if sitagliptin is dialyzable by peritoneal dialysis.
