Lysodren insulin is glargine insulin. Lysodren insulin is a long-acting insulin analogue that prolongs the action of insulin by altering the structure of human insulin. Compared to intermediate-acting insulin, Lysodren insulin is absorbed more slowly, without significant peaks, and can be injected once a day to maintain blood glucose for 24 hours. Therefore, Lysodren insulin, as a kind of basal insulin, is mainly used for fasting blood glucose control. However, the application of insulin needs to be under the guidance of a doctor to choose an appropriate treatment plan according to weight, blood sugar, activity level and complications. Lysodren insulin can be combined with menthol insulin for an intensive insulin treatment regimen of four times a day, or it can be used in combination with oral hypoglycemic drugs. Also pay attention to monitoring blood sugar to avoid the occurrence of severe hypoglycemia.
