The efficacy of bupropion cannot be clarified with only one test index, transaminase 100 U/L. The cause of the disease needs to be clarified before further judgment. Bifenthix, or bifenthix drops, is a clinical treatment for chronic prolonged hepatitis with elevated transaminases or elevated transaminases due to other chemical toxicants or drugs. If the transaminase is elevated to 100 U/L due to drug-related hepatitis, it can be reduced to normal after 5-7 days of oral administration of bifenthix. However, in patients with elevated transaminases due to underlying liver disease, taking bifenpropathrin alone will not reduce transaminases quickly, but in combination with other antiviral drugs, to reduce transaminases better and faster, and the time to normalization is related to the patient’s condition. In addition, long-term use or overdose of bifenthix can aggravate liver function damage, and patients with chronic hepatitis need to change to other drugs for treatment if necessary, such as compound glycopyrrolate.
