Clinical-Pharmacological Group

Oral hypoglycemic drug

Pharmacotherapeutic Group

Drugs for the treatment of diabetes mellitus; hypoglycemic drugs, other than insulins; dipeptidyl peptidase-4 (DPP-4) inhibitors

Pharmacological Action

Oral hypoglycemic agent, a highly selective inhibitor of dipeptidyl peptidase-4 (DPP-4).

Sitagliptin differs in chemical structure and pharmacological action from analogs of glucagon-like peptide-1 (GLP-1), insulin, sulfonylurea derivatives, biguanides, peroxisome proliferator-activated receptor (PPAR-γ) agonists, alpha-glucosidase inhibitors, and amylin analogs. By inhibiting DPP-4, Sitagliptin increases the concentration of two known incretin hormones: GLP-1 and glucose-dependent insulinotropic peptide (GIP). Incretin hormones are secreted in the intestine throughout the day, and their levels increase in response to food intake. Incretins are part of the internal physiological system regulating glucose homeostasis.

At normal or elevated blood glucose levels, incretin hormones contribute to increased insulin synthesis and its secretion by pancreatic beta-cells via intracellular signaling mechanisms associated with cyclic AMP. GLP-1 also helps suppress the increased secretion of glucagon by pancreatic alpha-cells. The decrease in glucagon concentration against the background of increased insulin levels leads to a reduction in glucose production by the liver, which ultimately results in decreased glycemia.

At low blood glucose concentrations, the listed effects of incretins on insulin release and reduction of glucagon secretion are not observed. GLP-1 and GIP do not affect glucagon release in response to hypoglycemia. Under physiological conditions, incretin activity is limited by the enzyme DPP-4, which rapidly hydrolyzes incretins into inactive products.

Sitagliptin prevents the hydrolysis of incretins by the DPP-4 enzyme, thereby increasing plasma concentrations of the active forms of GLP-1 and GIP. By increasing incretin levels, Sitagliptin enhances glucose-dependent insulin release and contributes to a reduction in glucagon secretion. In patients with type 2 diabetes mellitus with hyperglycemia, these changes in insulin and glucagon secretion lead to a decrease in the level of glycated hemoglobin HbA_1c and a reduction in plasma glucose concentration measured fasting and after a glucose tolerance test.

In patients with type 2 diabetes mellitus, a single dose of sitagliptin leads to inhibition of DPP-4 enzyme activity for 24 hours, resulting in a 2-3 fold increase in circulating incretins GLP-1 and GIP, an increase in plasma concentration of insulin and C-peptide, a decrease in plasma glucagon concentration, a reduction in fasting glycemia, as well as a decrease in glycemia after a glucose load or food load.

Pharmacokinetics

The pharmacokinetics of sitagliptin have been studied in healthy individuals and patients with type 2 diabetes mellitus.

After oral administration of the drug at a dose of 100 mg in healthy individuals, rapid absorption of sitagliptin is observed with C_max reached within 1-4 hours. AUC increases proportionally to the dose and in healthy subjects is 8.52 µmol × h after oral administration of a 100 mg dose, C_max was 950 nmol. The absolute bioavailability of sitagliptin is approximately 87%. Intra- and interindividual coefficients of variation for sitagliptin AUC are insignificant. Concurrent intake of fatty food does not affect the pharmacokinetics of sitagliptin.

Plasma AUC of sitagliptin increased by approximately 14% after the next dose of 100 mg upon reaching steady state after the first dose. After a single oral dose of 100 mg, the mean V_d of sitagliptin in healthy volunteers was approximately 198 L. The binding of sitagliptin to plasma proteins is 38%.

Only a small part of the administered drug is metabolized. After administration of ¹⁴C-labeled sitagliptin orally, approximately 16% of the radioactive drug was excreted as its metabolites. Traces of 6 metabolites of sitagliptin were detected, likely lacking DPP-4 inhibitory activity. In vitro studies have shown that the primary enzyme involved in the limited metabolism of sitagliptin is CYP3A4 with the participation of CYP2C8.

Approximately 79% of sitagliptin is excreted unchanged in the urine. Within 1 week after administration to healthy volunteers, ¹⁴C-labeled Sitagliptin was excreted: in urine – 87% and in feces – 13%. T_1/2 of sitagliptin after oral administration of a 100 mg dose is approximately 12.4 hours. Renal clearance is approximately 350 ml/min.

Elimination of sitagliptin occurs primarily through renal excretion via the mechanism of active tubular secretion. Sitagliptin is a substrate for the human organic anion transporter type 3 (hOAT-3), which may be involved in the renal elimination of sitagliptin. Sitagliptin is also a substrate for P-glycoprotein, which may also participate in the process of renal elimination of sitagliptin.

Indications

Monotherapy: as an adjunct to diet and exercise to improve glycemic control in type 2 diabetes mellitus;

Combination therapy: type 2 diabetes mellitus to improve glycemic control in combination with metformin or PPAR-γ agonists (e.g., thiazolidinedione), when diet and exercise in combination with monotherapy with the listed agents do not lead to adequate glycemic control.

Dosage Regimen

The method of application and dosage regimen for a specific drug depend on its form of release and other factors. The optimal dosage regimen is determined by the doctor. It is necessary to strictly adhere to the compliance of the dosage form of a specific drug with the indications for use and dosage regimen.

Administer orally once daily.

The recommended dose is 100 mg.

Take the tablet with or without food.

For patients with moderate renal impairment (creatinine clearance ≥30 to <50 mL/min), administer 50 mg once daily.

For patients with severe renal impairment (creatinine clearance <30 mL/min) or with end-stage renal disease requiring hemodialysis, administer 25 mg once daily.

Assess renal function before initiating therapy and periodically thereafter.

Administer the 25 mg and 50 mg doses using the corresponding strength tablets; do not split the 100 mg tablet to achieve these doses.

Dosage adjustment is not required for patients with hepatic impairment.

No dosage adjustment is recommended based on age, gender, race, or body mass index (BMI).

Adverse Reactions

From the respiratory system: upper respiratory tract infections (100 mg – 6.8%, 200 mg – 6.1%, placebo – 6.7%), nasopharyngitis (100 mg – 4.5%, 200 mg – 4.4%, placebo – 3.3%).

From the CNS: headache (100 mg – 3.6%, 200 mg – 3.9%, placebo – 3.6%).

From the digestive system: diarrhea (100 mg – 3%, 200 mg – 2.6%, placebo – 2.3%), abdominal pain (100 mg – 2.3%, 200 mg – 1.3%, placebo – 2.1%), nausea (100 mg – 1.4%, 200 mg – 2.9%, placebo – 0.6%), vomiting (100 mg – 0.8%, 200 mg – 0.7%, placebo – 0.9%).

Contraindications

Type 1 diabetes mellitus; diabetic ketoacidosis; pregnancy; lactation period (breastfeeding); children and adolescents under 18 years of age; hypersensitivity to sitagliptin.

Use in Pregnancy and Lactation

Contraindicated for use during pregnancy and lactation (breastfeeding).

Pediatric Use

The drug is contraindicated for use in children and adolescents under 18 years of age.

Geriatric Use

Elderly patients are more prone to developing renal failure. Accordingly, as in other age groups, dose adjustment is necessary in patients with severe renal impairment.

Special Precautions

Use with caution in patients with renal impairment. In moderate and severe renal impairment, as well as in patients with end-stage renal disease requiring hemodialysis, dose adjustment is required.

Elderly patients are more prone to developing renal failure. Accordingly, as in other age groups, dose adjustment is necessary in patients with severe renal impairment.

Drug Interactions

A slight increase in AUC (11%), as well as mean C_max (18%) of digoxin was noted when co-administered with sitagliptin. This increase is not considered clinically significant.

An increase in AUC and C_max of sitagliptin by 29% and 68%, respectively, was noted in patients with co-administration of sitagliptin in a single dose of 100 mg and cyclosporine (a potent P-glycoprotein inhibitor) in a single dose of 600 mg. These changes in the pharmacokinetic parameters of sitagliptin are not considered clinically significant.
