Description
Sitagliptin and Metformin Hydrochloride Extended-Release Tablets are a fixed-dose combination widely used in experimental studies involving type 2 diabetes mellitus (T2DM). This dual-action formulation features a DPP-4 inhibitor (sitagliptin) and a biguanide (metformin)—making it highly relevant for glucose metabolism, insulin resistance, and incretin pathway research.
Developed by Qilu Pharmaceutical (Hainan) Co., Ltd., this compound is approved under H20253718 and is intended exclusively for in vitro or in vivo laboratory research.
Not for human or animal consumption. For experimental use only.

Mechanism & Research Applications
This combination tablet works via two complementary mechanisms:
Sitagliptin inhibits DPP-4, increasing incretin hormones (GLP-1, GIP), enhancing insulin release and reducing glucagon in hyperglycemia.
Metformin reduces hepatic glucose production and improves peripheral glucose uptake.
Research applications include:
Glucose metabolism and insulin resistance studies
Evaluation of incretin pathway regulation
Investigations in combination therapy vs monotherapy efficacy
Experimental models of T2DM progression and treatment resistance
Preclinical pharmacokinetic and bioavailability analysis

Observed Effects in Research
Studies using this combination have reported:
Enhanced insulin sensitivity
Reduced postprandial glucose spikes
Improved -cell preservation
Attenuated hepatic gluconeogenesis
Synergistic glycemic control vs monotherapies Suitable for diabetes research
