Liver protectors are medications that protect liver function, specifically a class of medications that possess the ability to stabilize liver cell membranes, fight inflammation, and reduce liver transaminase and jaundice levels. Generally speaking, hepatoprotective drugs can be divided into three categories, which are anti-inflammatory and detoxifying hepatoprotective drugs, choleretic and hepatoprotective drugs, and antioxidant hepatoprotective drugs. 1. Anti-inflammatory and detoxification liver protection drugs: anti-inflammatory and detoxification liver protection drugs include glycyrrhizic acid and reduced glutathione, etc. These drugs have hormonal anti-inflammatory effects, but the side effects are smaller than those of hormones, and the adverse reactions are less. 2. Choleretic repair hepatoprotective drugs: choleretic drugs include ursodeoxycholic acid and adenosylmethionine, which can reduce bilirubin and improve jaundice in patients. Repair drugs mainly protect the liver cell membrane, the most representative is polyene phosphatidylcholine. 3. Antioxidant hepatoprotective drugs: Antioxidant hepatoprotective drugs are also a kind of commonly used hepatoprotective drugs, mainly dicyclomine and some Chinese herbs, such as schizandra, yin chen, etc. These drugs have been clinically proved to be effective for patients with jaundice. These drugs have been clinically proven to have better efficacy in acute and chronic liver diseases. Liver protection drugs are a large class of drugs that play an important role in protecting the liver, but the use of drugs should be standardized under the guidance of a doctor to avoid side effects or adverse reactions.
