Dapagliflozin is a column-like medicament acting on SGLT-2 target sites. Through the combination with the SGLT-2 of the kidney tubule, the glucose is inhibited from exerting glucose steady-state regulation effect, so that glucose cannot be reabsorbed back into blood by the kidney tubule, and finally, along with the urine discharged out of the body, the blood sugar of a human body is also reduced. Metformin can increase insulin sensitivity, so that the human body can use less insulin to achieve the effect of reducing blood sugar. The traditional effective treatment scheme is dapagliflozin combined with metformin, has a synergistic effect, can effectively regulate blood sugar of patients, and can also reduce adverse reactions.

Purchased from siella chemical technology (shandong) limited C21595-25g.
The adhesive I of the metformin hydrochloride sustained-release pellet core is selected from polyethylene oxide, the inventor discovers that the sustained-release performance can be obviously improved by using polyethylene oxide as the adhesive, and simultaneously discovers that the molecular weight of the polyethylene oxide has important significance on the release rate and biocompatibility of the drug, and the different molecular weights of the polyethylene oxide have different effects in the metformin hydrochloride sustained-release pellet core. It has been found that when the system according to the invention uses a viscosity average molecular weight of 1X10 5 The polyethylene oxide slow release effect is optimal. Because the molecular weight is too high, the solubility is too low, the uniformity of the sustained-release tablet is poor, and the sustained-release effect is poor because the molecular weight is too low.
