11 DESCRIPTION JANUVIA Tablets contain sitagliptin phosphate, an orally-active inhibitor of the dipeptidyl peptidase-4 (DPP-4) enzyme. Sitagliptin phosphate monohydrate is described chemically as 7-[(3 R )-3-amino-1-oxo-4-(2,4,5-trifluorophenyl)butyl]-5,6,7,8-tetrahydro-3-(trifluoromethyl)-1,2,4-triazolo[4,3- a ]pyrazine phosphate (1:1) monohydrate. The empirical formula is C 16 H 15 F 6 N 5 O•H 3 PO 4 •H 2 O and the molecular weight is 523.32. The structural formula is: Sitagliptin phosphate monohydrate is a white to off-white, crystalline, non-hygroscopic powder. It is soluble in water and N,N-dimethyl formamide; slightly soluble in methanol; very slightly soluble in ethanol, acetone, and acetonitrile; and insoluble in isopropanol and isopropyl acetate. Each film-coated tablet of JANUVIA contains 32.13, 64.25, or 128.5 mg of sitagliptin phosphate monohydrate, which is equivalent to 25, 50, or 100 mg, respectively, of free base and the following inactive ingredients: microcrystalline cellulose, anhydrous dibasic calcium phosphate, croscarmellose sodium, magnesium stearate, sodium stearyl fumarate, and propyl gallate.

⚠️ Warnings
• Ertugliflozin can lead to severe or life-threatening ketoacidosis especially in patients at risk e.g. those with acute fever, pancreatic disorder or
alcohol abuse
. The level of ketones in the urine should regularly be monitored even if the blood sugar is normal.
• Patients should be monitored for the signs and symptoms of volume depletion or low blood pressure during ertugliflozin therapy.
• Abnormalities of kidney function tests like increased serum creatinine levels or decreased glomerular filtration rate may occur during ertugliflozin therapy. Patients should be monitored for kidney function before and after initiating ertugliflozin therapy.
• Ertugliflozin can increase the risk of developing urinary tract infections (UTI) such as urosepsis or
pyelonephritis
(kidney infection). Patients should be monitored for the signs and symptoms of UTI and should be treated appropriately.
• Patients should be monitored for the signs and symptoms of pain, tenderness, ulcers or sores of the lower limbs, and bone infections such as osteomyelitis. Ertugliflozin therapy should be discontinued in such cases to avoid the risk of limb amputation.
• Increase in genital fungal or bladder infections have been observed in patients on ertugliflozin therapy. It is necessary to monitor to detect early and treat with appropriately. Patients who are uncircumcised or who have a history of genital fungal or bladder infections could be at a particularly higher risk.
• Patients who have high cholesterol levels should be monitored for the rise in the level of low-density lipoproteins and treated accordingly.
