Diabetes is a chronic disease that takes a long time to treat. Although the disease does not have a special drug, but medical research is actively researching the latest drugs for the treatment of diabetes, the current effect of drugs for the treatment of diabetic patients is still good. 1, oral hypoglycemia oral hypoglycemic drugs the main active ingredient is sulfonylurea, the role of the drug principle is to promote the release of insulin, greatly enhancing the sensitivity of target cells to insulin. This drug is one of the earliest applied oral hypoglycemic drugs, which has now powerfully developed to the third generation and is still the first-line drug for type 2 diabetes in clinical practice. It works mainly by stimulating insulin secretion and is most effective when taken half an hour before a meal. Such as commonly used methanesulfonylurea (D860), chlorosulfonylurea, eugenol, pyrisulfonylurea, methanesulfonylurea (Damecam), ketorol, glucophage, and regeneron, such as nandrolone. 2.Oral hypoglycemic sensitizers Glucose sensitizers are mainly biguanides, which are the oldest of oral hypoglycemic drugs and do not induce hypoglycemia, have cardiovascular protective effects other than hypoglycemia, increase the uptake and utilization of glucose by peripheral tissues, and reduce the high rate of hepatic glucose production. However, it is not recommended for patients with severe cardiac, hepatic, pulmonary and renal dysfunction. To reduce the gastrointestinal side effects of biguanides, it is generally recommended to take them after meals. Such as hypoglycemia, metformin, Gevalt, Lixin, Medicomat, Diabetes lozenges. 3.α-glucosidase inhibitors α-glucosidase inhibitors mainly reduce postprandial blood sugar. Such as baixin apples. 4.Zolidinediones mainly enhance the sensitivity of target tissues to insulin. Such as troglitazone, pioglitazone, rosiglitazone (vindia), etc. 5.Oral insulin The non-sulfonylurea insulin secretagogues developed in recent years are fast-acting, short-acting and effective, with few side effects. It is more commonly used in the late stage of treatment. It has good effect on postprandial blood sugar, so it is also called mealtime blood sugar regulator. It is taken before meal. There are three commonly used insulin analogues: one is lysergic insulin, the second is menthol insulin, and the third is glargine insulin. 6, oral hypoglycemic Chinese medicine Chinese medicine has a weak and slow anti-hyperglycemic effect, and the effect of lowering blood sugar is not as good as western medicine. The combination of western medicine with Chinese herbal medicine for the treatment of diabetes can reduce the dosage of western medicine and delay the expiration date of western medicine than the comparison of western medicine treatment alone. At present, there are nearly 40 kinds of Chinese patent medicines used to lower blood sugar, most of which are pure Chinese medicine, and a few of which are added with western medicine to lower blood sugar, such as hypochlorhydria pill, hypoglycemic Shu, Huangjing bitter melon capsule, etc. The symptoms are: thirsty and drinking, polyuria, polyphagia and easy hunger, emaciation, body fatigue, shortness of breath and lazy speech. Because of its precise efficacy, low price, ease of administration, safety and reliability, and good tolerability, it has been widely used in clinical practice and has become the most commonly taken by patients, frequently used by clinicians, and a brand name hypoglycemic drug with high popularity. However, when applying this drug in the clinic, attention should be paid to avoid the appearance of hypoglycemia. Huangjing Bitter Melon Capsules: (composed of ginseng, bitter melonin, propolis, wolfberry, gorgonian, yellow essence, chrysanthemum, mulberry, yucca, kudzu, astragalus, pig pancreas powder, etc.) This product is a pure Chinese medicine preparation, which can benefit qi and nourish yin, clear heat and dryness, eliminate the three excesses, lower blood sugar, open blood and activate blood vessels. It regulates blood sugar and prevents complications of diabetes. It can also be used for the prevention of hyperglycemia and hyperlipidemia in sub-healthy people. Both steroidal glycoside mixture and pyrimidine nucleoside, the main components of bitter melon, can inhibit the uptake of glucose by the small intestine. Pig pancreas powder contains a large amount of insulin and active islet cells, which not only directly replenishes insulin but also activates and repairs islet cells and restores the insulin secretion function of the pancreas, and has the advantages of being more convenient, safer and smoother than insulin injection.
