Janumet Tablet (Sitagliptin + Metformin) | Used to Treat Type 2 Diabetes
Janumet Tablet is used to treat type 2 diabetes and alongside diet and exercise to improve glycemic control in adults. It contains a combination of metformin and sitagliptin. Metformin and sitagliptin are oral diabetes medicines that help control blood sugar levels. Metformin works by decreasing glucose (sugar) production in the liver and decreasing absorption of glucose by the intestines. Sitagliptin works by regulating the levels of insulin your body produces after eating. Janumet is not for treating type 1 diabetes.
Product Overview
Janumet Tablet is a combination medication used to improve blood sugar control in adults with type 2 diabetes mellitus. It integrates two widely recognized anti-diabetic agents with complementary mechanisms: Sitagliptin, a DPP-4 inhibitor, and Metformin, a biguanide. This dual-action therapy is particularly effective when single-agent treatments or diet and exercise alone do not provide sufficient glycemic control. By addressing the multiple factors contributing to high blood sugar, Janumet helps patients maintain healthy glucose levels and reduces the long-term risk of diabetes-related complications.

| Storage | Store at room temperature (20°C to 25°C) |
| Packaging | Blister strips in a cardboard carton |
| Administration | Oral intake with meals |
| Primary Goal | Reduction of HbA1c and fasting glucose |
Mechanism of Action
- Sitagliptin works by slowing the breakdown of incretin hormones, which increases insulin release in response to rising blood sugar.
- It simultaneously lowers the amount of sugar produced by the liver by suppressing glucagon levels.
- Metformin improves insulin sensitivity, helping the body use its natural insulin more effectively.
- Metformin also reduces the amount of glucose absorbed from the intestines during digestion.
- Together, they provide a comprehensive approach to lowering both fasting and post-meal blood sugar levels.
Key Benefits
- Offers superior blood sugar control compared to taking Sitagliptin or Metformin alone.
- Lowers the risk of hypoglycemia (low blood sugar) when used as a primary combination therapy.
- Helps manage weight as it is generally weight-neutral or may lead to modest weight loss.
- Promotes better patient compliance by combining two essential medications into a single daily tablet.
- Supports long-term cardiovascular and kidney health by maintaining stable glucose targets.

Uses
Glycemic Control in Type 2 Diabetes: Used as an adjunct to diet and exercise to lower blood glucose levels in adult patients.
Combination Therapy: Provides a solution for patients whose blood sugar is not well-controlled on Metformin or Sitagliptin alone.
Reduction of Glucose Production: Works to decrease the amount of sugar the liver produces and releases into the bloodstream.
Enhanced Insulin Response: Helps the pancreas produce more insulin when blood sugar levels rise after eating.
Prevention of Diabetes Complications: Assists in maintaining long-term HbA1c targets to reduce the risk of nerve damage, kidney issues, and vision loss.
