Januvia (Sitagliptin) is an oral antidiabetic medicine belonging to class dipeptidyl peptidase-4 (DPP-4) inhibitor, manufactured by Merck & Co., was approved by the U.S. Food and Drug Administration (FDA) in 2006. In 2007, the FDA approved a variation of Januvia called Janumet, which is a combination of sitagliptin and metformin and is also made by Merck.
Sitagliptin is an anti-diabetic drug that works by increasing the levels of natural substances called incretins. Incretins help to control blood sugar by increasing insulin release, especially after a meal. They also decrease the amount of sugar your liver makes. It works by regulating the levels of insulin your body produces after eating.
The January 100 tablet belongs to a group of drugs called DPP-4 inhibitors (or gliptins). It works by helping to increase the amount of insulin your body produces after a meal and stopping your body from releasing too much glucose (sugar) into your bloodstream. The drug is usually taken once a day, has relatively few side effects, and is rarely the cause of weight gain.
Lowering blood sugar levels is an important part of controlling diabetes. If you control your condition, you can reduce your risk of serious diabetes problems such as kidney damage, eye damage, emotional problems, and loss of limbs. Properly controlled diabetes can also reduce the risk of heart disease and stroke. Taking this medication regularly with proper diet and exercise will help you to live a normal, healthy life. You should continue to use it as long as it is prescribed because it protects your future life.
Stop taking JANUVIA and call your doctor right away if you have severe and chronic stomach pain (stomach). Pain can be felt from your stomach to your back. Pain can be done with or without vomiting. This could be a sign of pancreatitis.
Before you start taking JANUVIA, tell your doctor if you have ever had a heart attack (your heart is not getting enough blood) or you have problems with your kidneys. Contact your doctor immediately if you are having difficulty breathing or have trouble breathing (especially if you are lying on the floor); swelling or fluid retention (especially on feet, ankles, or legs); abnormal rapid obesity; or unusual fatigue. These can be symptoms of heart failure.
Symptoms of allergies to JANUVIA, including rashes, chest and facial swelling, lips, tongue, and throat that may cause difficulty breathing or swallowing, may occur. If you have signs of a negative reaction, stop taking JANUVIA and call your doctor right away.
Kidney problems have been reported, sometimes requiring dialysis. Some people taking DPP-4 inhibitors such as JANUVIA may suffer from joint pain that can be very severe. Call your doctor if you have joint pain.
Tell your doctor right away if you have blisters or injuries on the outer layer of your skin (erosion). The dose of your sulfonylurea or insulin medication may need to be reduced while using JANUVIA. Signs and symptoms of low blood sugar can include headaches, drowsiness, weakness, dizziness, confusion, irritability, hunger, rapid heartbeat, sweating and nausea.
Your doctor can do a blood test before and during JANUVIA treatment to see how your kidneys are doing. Depending on these results, your doctor may change your JANUVIA dose.
JANUVIA tablets contain sixthliptin phosphate, an oral inhibitor of the enzyme dipeptidyl peptidase4 (DPP-4). Sitagliptin phosphate monohydrate is chemically defined as 7 - [(3R) -3-amino-1-oxo-4- (2,4,5trifluorophenyl) butyl] -5,6,7,8-tetrahydro-3- (trifluoromethyl ) - 1,2,4-triazolo [4,3-a] pyrazine phosphate (1: 1) monohydrate.
The art formula is C16H15F6N5O • H3PO4 • H2O and the molecular weight is 523.32.
Sitagliptin phosphate monohydrate is a white powder to white, crystalline, and non-hygroscopic. It is soluble in water and in N, N-dimethyl formamide; slightly soluble in methanol; slowly dissolves in ethanol, acetone, and acetonitrile; and does not contain isopropanol and isopropyl acetate.
Each tablet packed with JANUVIA film contains 32.13, 64.25, or 128.5 mg of sitagliptin phosphate monohydrate, equivalent to 25, 50, or 100 mg, respectively, free base and the following inactive ingredients: microcrystalline cellulose, anhydrous dibasic calcium phosphate, croscarmellose sodium, magnesium stearate, and sodium stearyl fumarate. In addition, the film cover contains the following inactive ingredients: polyvinyl alcohol, polyethylene glycol, talc, titanium dioxide, red iron oxide, and yellow iron oxide.
In patients with a higher glomerular filtration [GFR] or equal to 45 mL / min / 1.73 m2 to less than 90 mL / min / 1.73 m2, no dose adjustment of JANUVIA is required.
In patients with moderate renal impairment (large GFR or equivalent to 30 mL / min / 1.73 m2 to less than 45 mL / min / 1.73 m2), the dose of JANUVIA is 50 mg once daily.
In patients with severe renal impairment (eGFR less than 30 mL/min / 1.73 m2) or with renal insufficiency syndrome (ESRD) requiring hemodialysis or peritoneal dialysis, the dose of JANUVIA is 25 mg once daily. JANUVIA can be controlled without regard to dialysis time.
Because of the need for dose adjustment based on kidney function, kidney function tests are recommended before the start of JANUVIA and from time to time thereafter. There have been marketing reports after marketing kidney function in patients with kidney failure, some of whom have been given inappropriate doses of sitagliptin.

Januvia and Tradjenta are approved by the FDA for the treatment of type 2 diabetes, along with diet and exercise. A separate study of the two drugs was compared in a major review of the studies using a reliable source. The researchers looked at how well the Januvia and Tradjenta, may help to reduce the HBA1C levels. This is a measure of how well the blood glucose is controlled, over a period of several months. Januvius, was just as effective as Trajenta.
