Mechanism of Action

Alogliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor. It works by inhibiting the DPP-4 enzyme, which results in increased levels of incretin hormones. These hormones help regulate blood glucose by increasing insulin release and decreasing glucagon levels in a glucose-dependent manner.

Route of Administration

Alogliptin is administered orally in tablet form.

Pharmacokinetics

• Absorption
  • Rapidly absorbed with peak plasma concentrations occurring 1 - 2 hours after dosing. The absolute bioavailability is approximately 100%.
• Distribution
  • Alogliptin is 20 - 30% bound to plasma proteins
• Metabolism
  • Alogliptin does not undergo extensive metabolism, 60 - 70% of the dose is excreted as unchanged drug in the urine. Limited metabolism primarily via CYP2D6 and CYP3A4.
• Elimination
  • Primarily excreted unchanged in urine. The mean terminal half-life is approximately 21 hours.

Drug Precautions

Safety

Use with caution in patients with liver disease. Monitor liver functions tests regularly. Discontinue if pancreatitis or severe hypersensitivity reactions occur.

Pregnancy

Not recommended due to lack of sufficient data on safety.

Breast Feeding

Not recommended due to lack of sufficient data on safety.

Children and Elderly

Not recommended for children. Elderly patients should be monitored closely due to increased risk of adverse effects.

Renal Impairment

Dose adjustments are required for patients with moderate to severe renal impairment and ESRD.

Monitoring Requirements

Regular monitoring of liver function tests and renal function is recommended.

Drug Interaction

Caution with CYP2D6 and CYP3A4 inhibitors. Monitor for hypoglycemia when used with insulin or insulin secretagogues.

FAQs

How should I take the tablet?

Take alogliptin exactly as prescribed by your doctor, usually once daily, with or without food.

What should I avoid while taking?

Avoid alcohol and other medications that can affect liver function. Avoid useing alogliptin if you have a history of severe hypersensitivity reactions to DPP-4 inhibitors.

What happens if I miss a dose?
