Generic

Sitagliptin + Metformin Hydrochloride

Indications

When both sitagliptin and metformin medication is appropriate, this is advised as an addition to diet and exercise to enhance glycemic control in persons with type 2 diabetes mellitus. Important usage restrictions:

This should not be used in people with type 1 diabetes or to treat diabetic ketoacidosis because it is ineffective in these cases.

This has not been investigated in patients who have had pancreatitis in the past. It's unclear whether people who have had pancreatitis in the past are more likely to develop pancreatitis while using this.

Pharmacology

This pill combines two antihyperglycemic medicines with complimentary modes of action to help patients with type 2 diabetes improve their glycemic control. Metformin HCl, a member of the biguanide class, and Sitagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor. Sitagliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor that is thought to work in type 2 diabetes patients by reducing the inactivation of incretin hormones. The intestine releases incretin hormones throughout the day, including glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), and levels rise in response to a meal. T activates these hormones very quickly.

Dosage & Administration

Dose of film-coated tablet: The dosage of this tablet should be individualized on the basis of the patient's current regimen, efectiveness, and tolerability while not exceeding the maximum recommended daily dose of 100 mg sitagliptin and 2000 mg metformin. Initial combination therapy or maintenance of combination therapy should be individualized and left to the discretion of the health care provider.

This tablet should generally be given twice daily with meals, with gradual dose escalation, to reduce the gastrointestinal (GI) side efects due to metformin.

The starting dose of this tablet should be based on the patient’s current regimen. This tablet should be given twice daily with meals.

The recommended starting dose in patients not currently treated with metformin is 50 mg sitagliptin/500 mg metformin hydrochloride twice daily, with gradual dose escalation recommended to reduce gastrointestinal side efects associated with metformin.

The starting dose in patients already treated with metformin should provide sitagliptin dosed as 50 mg twice daily (100 mg total daily dose) and the dose of metformin already being taken. For patients taking metformin 850 mg twice daily, the recommended starting dose of this tablet is 50 mg sitagliptin/1000 mg metformin hydrochloride twice daily.

Interaction

Cationic Medicines: Cationic drugs are removed from the body by renal tubular secretion: Use at your own risk.

Phenprocoumon: Metformin may reduce phenprocoumon's anticoagulant effect. As a result, careful monitoring of the INR is advised.

Metformin's hypoglycemia effect can be reduced by taking levothyroxine. Blood glucose levels should be monitored, especially when thyroid hormone therapy is started or stopped, and metformin dosage should be modified if necessary.

Contraindications

Renal disease or renal dysfunction, as shown by serum creatinine values of 1.5 mg/dL [males], 1.4 mg/dL [females] or aberrant creatinine clearance, which can also be caused by situations including cardiovascular collapse (shock), acute myocardial infarction, and septicemia, is contraindicated.

Acute or chronic metabolic acidosis with or without coma, including diabetic ketoacidosis.

An allergic reaction to this tablet or sitagliptin in the past, such as anaphylaxis or angioedema.

Patients having radiologic examinations involving intravascular infusion of iodinated contrast materials should temporarily stop taking this pill.

Side Effects

Diarrhea, upper respiratory tract infection, and headache were the most prevalent adverse effects recorded in 5% of patients who started sitagliptin and metformin at the same time, and were more common than in placebo participants.

Hypoglycemia and headache were reported in 5% of patients treated with sitagliptin in combination with sulfonylurea and metformin, and were reported more frequently than in patients treated with placebo in combination with sulfonylurea and metformin.

In 5% of individuals treated with sitagliptin in combination with insulin and metformin, hypoglycemia was the sole adverse reaction reported, which was more common than in patients treated with placebo in combination.

Pregnancy & Lactation

Pregnancy Category B. There are no adequate and well-controlled studies in pregnant women with Sitagliptin Phosphate Monohydrate INN/Metformin Hydrochloride BP or its individual components; therefore, the safety of Sitagliptin Phosphate Monohydrate INN/Metformin Hydrochloride BP in pregnant women is not known. This tablet should be used during pregnancy only if clearly needed.

It is not known whether sitagliptin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when this tablet is administered to a nursing woman.

Precautions & Warnings

Lactic Acidosis- Lactic acidosis is a side effect of metformin use. Sepsis, dehydration, excessive alcohol use, hepatic insufficiency, renal impairment, and severe congestive heart failure all enhance the risk.

Malaise, myalgias, respiratory discomfort, increased somnolence, and nonspecific stomach distress are some of the symptoms. Low pH, increased anion gap, and high blood lactate are examples of laboratory abnormalities.

If acidosis is suspected, stop taking this tablet and admit the patient to the hospital right away.

Patients with hypothyroidism should have their thyroid-stimulating hormone (TSH) levels checked on a regular basis.

Metformin therapy for a long time has been linked .
