DAPAGLIFLOZIN AND SAXAGLIPTIN

Clinical summary

Indications and usage Dapagliflozin and saxagliptin tablets are indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. Limitations of Use Dapagliflozin and saxagliptin tablets are not recommended for use to improve glycemic control in patients with type 1 diabetes mellitus [ see WARNINGS AND PRECAUTIONS (5.1) ]. Standard dosing Assess renal function before initiation of therapy and periodically thereafter. ( 2.1 ) Take orally, once daily in the morning with or without food. ( 2.2 ) For patients not already taking dapagliflozin, the recommended starting dose of dapagliflozin and saxagliptin tablets is a 5 mg dapagliflozin/5 mg saxagliptin tablet once daily. ( 2.2 ) In patients tolerating 5 mg dapagliflozin and 5 mg saxagliptin once daily who require additional glycemic control, the dapagliflozin and saxagliptin tablets dose can be increased to 10 mg dapagliflozin/5 mg saxagliptin tablet once daily. ( 2.2 ) Swallow tablet whole. Do not crush, cut or chew. ( 2.2 ) Withhold dapagliflozin and saxagliptin for at least 3 days, if possible, prior to major surgery or procedures associated with prolonged fasting. ( 2.5 ) Dose forms and strengths 10 mg DAPAGLIFLOZIN; 5 mg SAXAGLIPTIN HYDROCHLORIDE DIHYDRATE Contraindications Dapagliflozin and saxagliptin is contraindicated in patients with: History of a serious hypersensitivity reactions to dapagliflozin or to saxagliptin, including anaphylactic reaction, angioedema or exfoliative skin conditions [ see WARNINGS AND PRECAUTIONS (5.8) and ADVERSE REACTIONS (6.2)]. Moderate to severe renal impairment (eGFR less than 45 mL/min/1.73 m 2 ), end-stage renal disease (ESRD), or patients on dialysis [ see USE IN SPECIFIC POPULATIONS (8.6)]. Key warnings Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis : Consider ketone monitoring in patients at risk for ketoacidosis, as indicated. Assess for ketoacidosis regardless of presenting blood glucose levels and discontinue dapagliflozin and saxagliptin if ketoacidosis is suspected. Monitor patients for resolution of ketoacidosis before restarting. ( 5.1 ) Pancreatitis: If pancreatitis is suspected, promptly discontinue dapagliflozin and saxagliptin. ( 5.2 ) Heart Failure: Consider risks and benefits of dapagliflozin and saxagliptin in patients who have known risk factors for heart failure. Monitor patients for signs and symptoms. ( 5.3 ) Volume Depletion: Before initiating dapagliflozin and saxagliptin, assess volume status and renal function in the elderly, patients with renal impairment or low systolic blood pressure, and in patients on diuretics. Monitor for signs and symptoms during therapy. ( 5.4 ) Urosepsis and Pyelonephritis: Evaluate for signs and symptoms of urinary tract infections and treat promptly, if indicated. ( 5.5 ) Hypoglycemia: Consider lowering the dose of insulin secretagogue or insulin to reduce the risk of hypoglycemia when initiating dapagliflozin and saxagliptin. ( 5.6 ) Necrotizing Fasciitis of the Perineum (Fournier’s Gangrene): Serious, life-threatening cases have occurred in both females and males. Assess patients presenting with pain or tenderness, erythema, or swelling in the genital or perineal area, along with fever or malaise. If suspected, institute prompt treatment. ( 5.7 ) Hypersensitivity Reactions : There have been postmarketing reports of serious hypersensitivity reactions in patients treated with saxagliptin, such as anaphylaxis, angioedema, and exfoliative skin conditions. Promptly discontinue dapagliflozin and saxagliptin, assess for other potential causes, institute appropriate monitoring and treatment, and initiate alternative treatment for diabetes. ( 5.8 ) Genital Mycotic Infections: Monitor and treat if indicated. ( 5.9 ) Arthralgia: Severe and disabling arthralgia has been reported in patients taking DPP-4 inhibitors. Consider as a possible cause for severe joint pain and discontinue drug if appropriate. ( 5.10 ) Bullous Pemphigoid: There have been postmarketing reports of bullous pemphigoid requiring hospitalization in patients taking DPP-4 inhibitors. Tell patients to report development of blisters or erosions. If bullous pemphigoid is suspected, discontinue dapagliflozin and saxagliptin. ( 5.11 ) Drug interactions Table 3 : Clinically Relevant Interactions with Dapagliflozin and Saxagliptin Strong Inhibitors of CYP3A4/5 Enzymes Clinical Impact Ketoconazole significantly increased saxagliptin exposure. Similar significant increases in plasma concentrations of saxagliptin are anticipated with other strong CYP3A4/5 inhibitors (e.g., atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, ritonavir, saquinavir, and telithromycin). Intervention Do not coadminister dapagliflozin and saxagliptin with strong cytochrome P450 3A4/5 inhibitors [see DOSAGE AND ADMINISTRATION (2.4) and CLINICAL PHARMACOLOGY (12.3) ] . Insulin or Insulin Secretagogues Clinical Impact The risk o
