Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical processing mold technology, specifically to a stamping mold for metformin hydrochloride sustained-release tablets. Background Technology

[0002] Metformin hydrochloride extended-release tablets are an oral hypoglycemic agent that primarily lowers blood glucose levels by reducing hepatic glucose output, improving peripheral tissue sensitivity to insulin, and increasing glucose uptake and utilization. It is mainly suitable for type 2 diabetic patients who are overweight or have high insulin levels, especially those whose blood glucose cannot be effectively controlled through diet and exercise.

[0003] Existing metformin hydrochloride sustained-release tablet stamping dies, after long-term use, may exhibit varying degrees of wear on different parts of the die surface due to the continuous friction and compression of the tablet raw material. This necessitates significant time-consuming regular maintenance and upkeep, including surface polishing and applying wear-resistant coatings, which undoubtedly increases production costs. Furthermore, severely worn dies may require complete replacement, resulting in substantial resource waste. Therefore, we propose a metformin hydrochloride sustained-release tablet stamping die to address the aforementioned problems. Utility Model Content
