For patients with type-2 diabetes mellitus, Tesavel is indicated to improve glycaemic control: as monotherapy: in patients inadequately controlled by diet and exercise alone and for whom metformin is inappropriate due to contraindications or intolerance; as dual oral therapy in combination with: metformin when diet and exercise plus metformin alone do not provide adequate glycaemic control; a sulphonylurea when diet and exercise plus maximal tolerated dose of a sulphonylurea alone do not provide adequate glycaemic control and when metformin is inappropriate due to contraindications or intolerance; a PPAR? agonist (i.e. a thiazolidinedione) when use of a PPAR? agonist is appropriate and when diet and exercise plus the PPAR? agonist alone do not provide adequate glycaemic control; as triple oral therapy in combination with a sulphonylurea and metformin when diet and exercise plus dual therapy with these agents do not provide adequate glycaemic control; a peroxisome-proliferator-activated-receptor-gamma (PPAR?) agonist and metformin when use of a PPAR? agonist is appropriate and when diet and exercise plus dual therapy with these agents do not provide adequate glycaemic control. Tesavel is also indicated as add on to insulin (with or without metformin) when diet and exercise plus stable dosage of insulin do not provide adequate glycaemic control.
