Uses Of TRAJENTA DUO 2.5/500MG TABLET
- Type II diabetes mellitus
Benefits of TRAJENTA DUO 2.5/500MG TABLET in Type II diabetes mellitus:
- Improved Blood Sugar Control: TRAJENTA DUO 2.5/500MG TABLET works by reducing glucose production in the liver and improving insulin sensitivity. It also helps increase insulin secretion in response to meals, effectively lowering blood sugar levels.
- Reduced Risk of Hypoglycemia: Because TRAJENTA DUO 2.5/500MG TABLET does not cause significant insulin release in the absence of food, the risk of low blood sugar (hypoglycemia) is lower compared to other diabetes medications.
- Weight Neutrality: The Metformin present in the medicine often helps in weight management, and linagliptin present in the medicine typically has a neutral effect on weight, making this combination a better choice for individuals concerned about weight gain.
- Cardiovascular Benefits: Linagliptin has shown to have potential cardiovascular protective benefits, which can be important for diabetic patients who are at an increased risk for heart-related issues.
How TRAJENTA DUO 2.5/500MG TABLET Works
TRAJENTA DUO 2.5/500MG TABLET is an antidiabetic medicine. It contains two medicines namely Metformin and Linagliptin. Metformin makes the body more sensitive to insulin (a hormone involved in glucose metabolism). This helps our body cells to utilize more amount of the circulating blood glucose. Additionally, it can stop glucose production by the liver and reduces its absoprtion in the body. Linagliptin controls blood sugar levels by blocking the actions of an enzyme called dipeptidyl peptidase (DPP)-4 that reduces insulin secretion in the body. Collectively, TRAJENTA DUO 2.5/500MG TABLET controls blood sugar levels and improve glycemic control in patients with type II diabetes.

Interactions
A, Drug-Drug interactions:
1. Other Antidiabetic Medications (Ex. Sulfonylureas and Insulin)
Interaction: Concurrent use with TRAJENTA DUO 2.5/500MG TABLET can increase the risk of hypoglycemia (low blood sugar) and other side effects
Effect: Enhanced blood sugar control but a higher risk of hypoglycemia.
2. Diuretics (Ex. furosemide)
Interaction: May potentiate the risk of lactic acidosis due to dehydration, particularly in metformin users.
Effect: Increased risk of dehydration, electrolyte imbalance, and hypoglycemia.
3.ACE Inhibitors (Ex. enalapril)
Interaction: Can improve insulin sensitivity, altering blood sugar levels and increasing the risk of hypoglycemia.
Effect: Increased risk of dehydration, electrolyte imbalance, and hypoglycemia.
3. Medications Affecting Renal Function
Interaction
- NSAIDs (Ex. ibuprofen) and contrast agents: May reduce kidney function, increasing the risk of metformin-induced lactic acidosis.
- Loop diuretics: Increase the risk of dehydration and subsequent kidney impairment.
Effect: Elevated levels of metformin due to reduced clearance.
4. Beta-Blockers (Ex. atenolol, propranolol)
Interaction: Can mask symptoms of hypoglycemia, such as rapid heartbeat or sweating, making it harder to detect low blood sugar.
Effect: Delayed recognition and management of hypoglycemia.
5. Rifampin (Rifampicin)
Interaction: Rifampin can reduce the effectiveness of linagliptin by inducing its metabolism, leading to suboptimal blood sugar control.
Effect: Reduced efficacy of Linaxa M in managing diabetes.
6. Medications Affecting Vitamin B12 Absorption
Interaction: Long-term use of metformin in Linaxa M can decrease vitamin B12 levels, potentially causing deficiency.
Effect: Anemia and neuropathy, which may worsen diabetes-related complications.
7. Thyroid Medications (Ex. Levothyroxine)
Interaction: Thyroid hormones can increase blood sugar levels, reducing the efficacy of Linaxa M.
Effect: Reduced glycemic control.
8. Corticosteroids (Ex. hydrocortisone) and Oral Contraceptives
Interaction: These medications can counteract the effects of Linaxa M by increasing blood sugar levels.
Effect: Hyperglycemia, reducing the effectiveness of diabetes management.
9. Anticoagulants (Ex. Warfarin)
Interaction: Altered blood glucose levels can impact the efficacy of anticoagulants.
Effect: Risk of blood sugar fluctuations interfering with anticoagulant management.
