There are many kinds of hepatoprotective drugs, such as compound glycyrrhetinic acid, reduced glutathione, polyenyl phosphatidylcholine, pentosidine preparations, and components of herbal medicines. How to use liver-protective drugs needs to be based on the nature of the disease and the underlying disease of the patient. If the patient suffers from hypertension and hypokalemia, glycopyrrolate preparations are not recommended; if the patient suffers from fatty liver, alcoholic liver, etc., polyenophosphatidylcholine is recommended as the main option; if the patient is a pregnant patient, drugs such as compound glycopyrrolate cannot be applied. At the same time, relevant indexes need to be tested, and liver protection alone should not be the main focus. It is recommended to go to a general hospital for evaluation, and then to choose the relevant drugs correctly.
