Correct usage and dosage of Trelagliptin and dose adjustment plans for different patients

Trelagliptin (Trelagliptin) is a DPP-4 inhibitor hypoglycemic drug. It is characterized by long-acting effects. Therefore, unlike common once-daily drugs such as sitagliptin and linagliptin, trelagliptin usually only needs to be taken orally once a week. The recommended standard dose is 100mg once a week, before or after meals, regardless of food intake. Due to its convenient administration, it can greatly improve patient compliance and is suitable for patients with type 2 diabetes who require long-term oral hypoglycemic drugs.

For Patients with normal or mildly impaired renal function generally do not need to adjust the dose and should still use it at the standard dose. However, in patients with moderate renal impairment , because the drug may accumulate, doctors usually evaluate the patient's glomerular filtration rate (eGFR) and decide whether to reduce the dose or extend the dosing interval based on the situation. As for patients with severe renal insufficiency or undergoing dialysis treatment, the use of trotagliptin is usually not recommended, and other more appropriate antidiabetic drugs need to be selected based on individual circumstances.

For elderly patients Since they may be accompanied by a variety of underlying diseases and decreased renal function, clinical assessment should be based on the overall condition of the patient to assess whether the dose needs to be adjusted. Although clinical trials have shown that trolagliptin is well tolerated in the elderly, the risk of hypoglycemia still needs to be noted, especially when used in combination with insulin or sulfonylureas and appropriate dose reduction should be considered.

For patients with mild to moderate hepatic impairment, special adjustments are usually not required. However, for patients with severe hepatic impairment, due to the lack of sufficient clinical data, it is recommended to use it with caution or avoid use. Generally speaking, the dosing regimen of trolagliptin is relatively simple. The core principle is standard dose100 mg once a week. In special groups, individual adjustments need to be made based on renal function, age and concomitant medication.
