Description

Sitagliptin Phosphate Tablets USP belong to the Dipeptidyl Peptidase-4 (DPP-4) inhibitor class of oral antidiabetic agents. These tablets work by increasing incretin levels (GLP-1 and GIP), which in turn enhance insulin secretion and suppress glucagon release, leading to improved blood glucose control. Sitagliptin is not an insulin substitute but complements diet, exercise, and other antidiabetic agents to optimize glycemic management.

Pharmacological Classification

ATC Classification: A10BH01 – Dipeptidyl Peptidase-4 (DPP-4) Inhibitor
Mechanism of Action: Sitagliptin inhibits the DPP-4 enzyme responsible for the degradation of incretin hormones. By prolonging the activity of incretin hormones, Sitagliptin enhances insulin release and reduces glucagon secretion, effectively controlling blood glucose levels without causing hypoglycemia.

Therapeutic Indications

Sitagliptin Phosphate Tablets USP are indicated for the management of Type 2 Diabetes Mellitus in adults. They are used:

  • As monotherapy in patients who cannot tolerate metformin.
  • In combination therapy with metformin, sulfonylureas, or thiazolidinediones when monotherapy is insufficient.
  • As part of a comprehensive diabetes management plan, including diet control and regular exercise.

By controlling blood sugar levels, Sitagliptin helps prevent diabetes-related complications such as nephropathy, retinopathy, neuropathy, cardiovascular events, and sexual dysfunction.

Dosage and Administration

The dosage should be individualized based on the patient’s medical condition, renal function, and treatment response.

  • Recommended Dose: 100mg once daily by mouth, with or without food.
  • Renal Impairment Adjustments: Dose reduction may be necessary for patients with moderate to severe renal impairment.
  • Dosage Direction: As directed by the physician.

Important: Swallow the tablet whole with water. Do not chew, crush, or break the tablet.

Pharmaceutical Form and Appearance

  • Sitagliptin 25mg: Yellow, film-coated round tablet.
  • Sitagliptin 50mg: Light red, film-coated round tablet.
  • Sitagliptin 100mg: Yellow, film-coated oval tablet.

Each tablet is engraved for easy identification and packaged in moisture-resistant aluminum blisters or HDPE bottles to maintain potency.

Storage and Stability

  • Storage Condition: Store below 30°C in a dry place, away from direct sunlight and heat.
  • Humidity Protection: Keep the container tightly closed to protect from moisture.
  • Shelf Life: 24 months from the date of manufacture.
  • Temperature Guidelines: Controlled room temperature between 20°C and 25°C (68°F – 77°F) with permissible excursions between 15°C and 30°C (59°F – 86°F).

Clinical Pharmacology

Mechanism of Action: Sitagliptin selectively inhibits DPP-4, preventing the degradation of GLP-1 and GIP. These hormones stimulate insulin release and suppress glucagon secretion, reducing hepatic glucose output.
Pharmacokinetics:

  • Absorption: Rapidly absorbed after oral administration, with peak plasma concentration within 1–4 hours.
  • Bioavailability: Approximately 87%.
  • Metabolism: Minimal hepatic metabolism; primarily excreted unchanged in urine.
  • Half-life: Approximately 12 hours.
  • Excretion: Primarily renal via active tubular secretion.

Adverse Reactions

Sitagliptin is generally well-tolerated. Possible side effects include:

  • Nasopharyngitis
  • Headache
  • Upper respiratory tract infection
  • Hypoglycemia (especially when combined with sulfonylureas)
  • Mild gastrointestinal discomfort

Severe adverse events are rare but may include pancreatitis or hypersensitivity reactions. Immediate medical attention is advised if severe abdominal pain or allergic symptoms occur.


Drug Interactions

Sitagliptin has a low potential for drug-drug interactions. However, dose adjustments may be required when used with:

  • Sulfonylureas (risk of hypoglycemia)
  • Insulin (enhanced glucose-lowering effect)
  • Strong CYP3A4 inhibitors or P-gp inhibitors

Therapeutic Advantages

  • Provides effective glycemic control without weight gain
  • Low risk of hypoglycemia when used as monotherapy
  • Suitable for elderly and renal-impaired patients with adjusted dosing
  • Can be combined with Metformin or Insulin for synergistic effects
  • Promotes better treatment adherence due to once-daily dosing

Packaging and Presentation

Available in various pack sizes for patient convenience and institutional supply:

  • 30 Tablets Pack – Hospital and retail use
  • 90 Tablets Pack – Long-term therapy pack
  • 100 Tablets Pack – Institutional and export packaging
