Sitagliptin SUN is a medicine used to control blood glucose (sugar) levels in adults with type 2 diabetes. It is used together with diet and exercise in the following ways:
Sitagliptin SUN contains the active substance sitagliptin and is a ‘generic medicine’. This means that Sitagliptin SUN contains the same active substance and works in the same way as a ‘reference medicine’ already authorised in the EU called Januvia. For more information on generic medicines, see the question-and-answer document here.
Sitagliptin SUN is available as tablets and can only be obtained with a prescription. The recommended dose is 100 mg once a day. The dose may be lowered in some patients with reduced kidney function. If Sitagliptin SUN is taken with a sulphonylurea or insulin, the dose of the sulphonylurea or insulin may need to be lowered to reduce the risk of hypoglycaemia (low blood glucose levels).
For more information about using Sitagliptin SUN, see the package leaflet or contact your doctor or pharmacist.
Type 2 diabetes is a disease in which the pancreas does not make enough insulin to control the level of glucose in the blood or when the body is unable to use insulin effectively. The active substance in Sitagliptin SUN, sitagliptin, is a dipeptidyl-peptidase-4 (DPP-4) inhibitor. It works by blocking the breakdown of ‘incretin’ hormones in the body. These hormones are released after a meal and stimulate the pancreas to produce insulin. By increasing levels of incretin hormones in the blood, sitagliptin stimulates the pancreas to produce more insulin when blood glucose levels are high. Sitagliptin does not work when blood glucose levels are low. Sitagliptin also reduces the amount of glucose made by the liver, by increasing insulin levels and decreasing the levels of the hormone glucagon. Together, these processes reduce blood glucose levels and help to control type 2 diabetes.
Studies on the benefits and risks of the active substance in the authorised uses have already been carried out with the reference medicine, Januvia, and do not need to be repeated for Sitagliptin SUN.
As for every medicine, the company provided data on the quality of Sitagliptin SUN. The company also carried out a study that showed that it is ‘bioequivalent’ to the reference medicine. Two medicines are bioequivalent when they produce the same levels of the active substance in the body and are therefore expected to have the same effect.
Because Sitagliptin SUN is a generic medicine and is bioequivalent to the reference medicine, its benefits and risks are taken as being the same as the reference medicine’s.
The European Medicines Agency concluded that, in accordance with EU requirements, Sitagliptin SUN has been shown to have comparable quality and to be bioequivalent to Januvia. Therefore, the Agency’s view was that, as for Januvia, the benefits of Sitagliptin SUN outweigh the identified risks and it can be authorised for use in the EU.
Recommendations and precautions to be followed by healthcare professionals and patients for the safe and effective use of Sitagliptin SUN have been included in the summary of product characteristics and the package leaflet.
As for all medicines, data on the use of Sitagliptin SUN are continuously monitored. Suspected side effects reported with Sitagliptin SUN are carefully evaluated and any necessary action taken to protect patients.
Sitagliptin SUN received a marketing authorisation valid throughout the EU on 09 December 2021.

Product information documents contain:
For adult patients with type 2 diabetes mellitus, Sitagliptin SUN 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 peroxisome proliferator-activated receptor gamma (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 medicinal products do not provide adequate glycaemic control.
- a PPAR? agonist and metformin when use of a PPAR? agonist is appropriate and when diet and exercise plus dual therapy with these medicinal products do not provide adequate glycaemic control.
Sitagliptin SUN is also indicated as add-on to insulin (with or without metformin) when diet and exercise plus stable dose of insulin do not provide adequate glycaemic control.
