Sitagliptin F.C tablet



inhibitor of the dipeptidyl peptidase-4 (DPP-4) enzyme.                          (Drug Facts)


Sitagliptin phosphate monohydrate is described chemically as 7-[(3R)-3-amino-4-(2,4,5trifluorophenyl)butanoyl] -3-(trifluoromethyl)- 5,6,7,8-tetrahydro -1,2,4-triazolo[4,3-a]pyrazine monophosphate monohydrate. C16H15F6N5O•H3PO4•H2O=523.3

Mechanism of action:

DPP-4 inhibitor; therefore, increase and prolongs incretin hormone activity, which is inactivated by DPP-4 enzyme

Incretins increase insulin release and synthesis from pancreatic beta cells and reduce glucagon secretion from pancreatic alpha cells.

Sitagliptin is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.                                                                  (PDR)


Known serious hypersensitivity (e.g., anaphylaxis, angioedema) to sitagliptin or any ingredient in formulation.                                                                                  (PDR)

Warnings & Precautions:

1.Tell your doctor if you have or have had:

  • a disease of the pancreas (such as pancreatitis)
  • gallstones, alcohol dependence or very high levels of triglycerides (a form of fat) in your blood. These medical conditions can increase your chance of getting pancreatitis
  • type 1 diabetes
  • diabetic ketoacidosis (a complication of diabetes with high blood sugar, rapid weight loss, nausea or vomiting)
  • any past or present kidney problems.
  • an allergic reaction to  Sitagliptin

2.Children and adolescents below 18 years should not use this medicine.

3.Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

-          In particular, tell your doctor if you are taking digoxin (a medicine used to treat heart problems). The level of digoxin in your blood may need to be checked if taking with Sitagliptin.

4.This medicine has no or negligible influence on the ability to drive and use machines. However, dizziness and drowsiness have been reported, which may affect your ability to drive or use machines.

Drug Interactions:

Drugs Metabolized by Hepatic Microsomal Enzymes

Does not inhibit CYP isoenzymes 1A2, 2B6, 2C8, 2C9, 2C19, 2D6, or 3A4 in vitro or induce CYP3A4. Pharmacokinetic interactions with drugs metabolized by these isoenzymes unlikely.

Inhibitors of P-glycoprotein Transport System

Substrate of p-glycoprotein transport system. Potential pharmacokinetic interaction (increased absorption and renal clearance of sitagliptin) with p-glycoprotein inhibitors

Clinically important pharmacokinetic interactions with p-glycoprotein inhibitors unlikely. Does not appear to inhibit p-glycoprotein transport system.

Drugs Secreted by Renal Tubular Cationic Transport

Substrate of organic anion transport system; pharmacokinetic interaction unlikely with substrates of organic cationic transport system.

Protein-bound Drugs

Pharmacokinetic interaction unlikely

Adverse Reactions:

Adverse effects reported with sitagliptin include upper respiratory-tract infections, headache, and nasopharyngitis. Hypersensitivity reactions including anaphylaxis, angioedema, urticaria, rash, and Stevens-Johnson syndrome have also been reported.
