SITAGLIPTIN ASCEND

Posology The dose is 100 mg sitagliptin once daily. When used in combination with metformin and/or a PPAR agonist, the dose of metformin and/or PPAR agonist should be maintained, and sitagliptin administered concomitantly. 4). If a dose of sitagliptin is missed, it should be taken as soon as the patient remembers.

A double doseshould not be taken on the same day. Special populations Renal impairment When considering the use of sitagliptin in combination with another anti-diabetic medicinal product, its conditions for use in patients with renal impairment should be checked.

For patients with mild renal impairment (glomerular filtration rate [GFR]  60 to < 90 ml/min), nodose adjustment is required. For patients with moderate renal impairment (GFR  45 to < 60 mL/min), no dosage adjustment isrequired. For patients with moderate renal impairment (GFR  30 to < 45 mL/min), the dose of sitagliptin is 50 mg once daily.

For patients with severe renal impairment (GFR ≥ 15 to <30 mL/min) or with end- stage renal disease (ESRD) (GFR < 15 mL/min), including those requiring haemodialysis or peritoneal dialysis, the dose of sitagliptin is 25 mg once daily.

Treatment may be administered without regard to the timing of dialysis. Because there is a dosage adjustment based upon renal function, assessment of renal function isrecommended prior to initiation of sitagliptin and periodically thereafter.

Hepatic impairment No dose adjustment is necessary for patients with mild to moderate hepatic impairment. 2). However, because sitagliptin is primarily renally eliminated, severe hepatic impairment is notexpected to affect the pharmacokinetics of sitagliptin.

Elderly No dose adjustment is necessary based on age. Paediatric population Sitagliptin should not be used in children and adolescents 10 to 17 years of age because of insufficient efficacy. 2. Sitagliptin has not been studied in paediatric patients under 10 years of age Method of administration Sitagliptin can be taken with or without food.

Summary of the safety profile Serious adverse reactions including pancreatitis and hypersensitivity reactions have been reported. 4). Tabulated list of adverse reactions Adverse reactions are listed below (Table 1) by system organ class and frequency.

Frequencies are defined as: very common (≥ 1/10); common (≥ 1/100 to < 1/10); uncommon (≥ 1/1,000 to < 1/100); rare (≥ 1/10,000 to < 1/1,000); very rare (< 1/10,000) and not known (cannot be estimated from the available data). Table 1.

General Sitagliptin should not be used in patients with type 1 diabetes or for the treatment of diabeticketoacidosis. Acute pancreatitis Use of DPP-4 inhibitors has been associated with a risk of developing acute pancreatitis. Patients should be informed of the characteristic symptom of acute pancreatitis: persistent, severe abdominal pain.

Resolution of pancreatitis has been observed after discontinuation of sitagliptin (with or without supportive treatment), but very rare cases of necrotising or haemorrhagic pancreatitis and/or death have been reported. If pancreatitis is suspected, sitagliptin and other potentially suspect medicinal products should be discontinued; if acute pancreatitis is confirmed, sitagliptin should not be restarted.

Caution should be exercised in patients with a history of pancreatitis. e. metformin and/or a PPAR agonist), rates ofhypoglycaemia reported with sitagliptin were similar to rates in patients taking placebo. Hypoglycaemia has been observed when sitagliptin was used in combination with insulin or a sulphonylurea.

2). Renal impairment Sitagliptin is renally excreted. 2). When considering the use of sitagliptin in combination with another anti-diabetic medicinal product, its conditions for use in patients with renal impairment should be checked.

Hypersensitivity reactions Post-marketing reports of serious hypersensitivity reactions in patients treated with sitagliptin have been reported. These reactions include anaphylaxis, angioedema, and exfoliative skin conditions including Stevens-Johnson syndrome.

Onset of these reactions occurred within the first 3 months after initiation of treatment, with some reports occurring after the first dose. If a hypersensitivity reaction is suspected, sitagliptin should be discontinued. Other potential causes for the event should be assessed, and alternative treatment for diabetes initiated.
