A box of Dagliflozin is relatively expensive at around$230. Dagliflozin belongs to glucose-lowering drugs, but the glucose-lowering mechanism of this drug is different from other drugs. Dagliflozin mainly reduces the reabsorption of glucose in the kidneys by increasing the filtration rate of the glomerulus, thus excreting the excess sugar tissues from the body, which has the effect of lowering blood sugar. Because it acts on the kidneys and promotes the excretion of tissue fluid by the kidneys, it also causes partial loss of electrolytes while lowering sugar. Although this drug is effective in lowering blood sugar, care should be taken to avoid hypotension and electrolyte disturbance during the medication. During the period of use, kidney and electrolyte examination should be carried out in time to avoid acute renal failure and other substantial damage, and if complications occur, it should be stopped in time.
