Indication
Gluvan Plus is indicated as an adjunct to diet and exercises to improve glycaemic control in patients with type 2 diabetes mellitus whose diabetes is not adequately controlled on Metformin Hydrochloride or Vildagliptin alone or who are already treated with the combination of Vildagliptin and Metformin Hydrochloride, as separate tablets.
Dosage & Administration
Adults: Based on the patient’s current dose of Metformin, Gluvan Plus may be initiated at either 50 mg/500 mg or 50 mg/850 mg twice daily, 1 tablet in the morning and the other in the evening. Patients receiving Vildagliptin and Metformin from separate tablets may be switched to Gluvan Plus containing the same doses of each component. Doses higher than 100 mg of vildagliptin are not recommended. There is no clinical experience of Vildagliptin and Metformin in triple combination with other antidiabetic agents. Taking Gluvan Plus with or just after food may reduce gastrointestinal symptoms associated with Metformin.
Contraindications
This combination is contraindicated in patients with known hypersensitivity to Vildagliptin or Metformin Hydrochloride or to any of the excipients. It is contraindicated in patients with renal disease or renal dysfunction, acute myocardial infarction, and septicaemia. It is also contraindicated in patients with congestive heart failure patients and in patients with acute or chronic metabolic acidosis, including diabetic ketoacidosis, with or without coma. It should be temporarily discontinued in patients undergoing radiologic studies involving intravascular administration of iodinated contrast materials, because use of such products may result in acute alteration of renal function.
Side effects
The most common side effects are headache, tremor, dizziness, nausea, hypoglycaemia etc.
Drug interaction
No clinically relevant pharmacokinetic interaction was observed when Vildagliptin (100 mg once daily) was co-administered with Metformin Hydrochloride (1,000 mg once daily). Vildagliptin has a low potential for drug interactions. Since Vildagliptin is not a cytochrome P (CYP) 450 enzyme substrate nor does it inhibit nor induces CYP 450 enzymes, it is not likely to interact with co-medications that are substrates, inhibitors or inducers of these enzymes. As a result of these studies no clinically relevant interactions with other oral antidiabetics (glibenclamide, pioglitazone, metformin hydrochloride), amlodipine, digoxin, ramipril, Simvastatin, valsartan or warfarin were observed after co-administration with vildagliptin. On the other hand, Furosemide, Nifedipine and glyburide increase Cmax and blood AUC of Metformin with no change in renal clearance of Metformin.
