A complete description of the six-month liver function changes and safety monitoring plan for long-term use of Pretomanid

Pretomanid is a new anti-tuberculosis drug mainly used for the combination treatment of multidrug-resistant tuberculosis (MDR-TB) or extensively drug-resistant tuberculosis (XDR-TB). During long-term use, liver function is one of the most important monitoring indicators to pay attention to. Clinical data shows that after using putomanid for about half a year, some patients may experience a mild increase in transaminase, but most cases are reversible, and liver function can return to normal after stopping the drug or adjusting the combination regimen. Therefore, regular monitoring of liver function is crucial to ensure patient safety during long-term treatment.

Regarding the specific monitoring plan, it is recommended to conduct a basic liver function assessment before medication, including indicators such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, and alkaline phosphatase. In the early stages of taking the medication, you should review it every 2 to 4 weeks to detect abnormalities as early as possible. If mild transaminase elevation is found but no symptoms, medication can be continued under the guidance of a doctor and follow-up visits should be strengthened; if the elevation exceeds 3 times the normal upper limit or is accompanied by symptoms such as jaundice and fatigue, the treatment plan should be adjusted immediately or the medication should be temporarily discontinued.

In the context of combined use of putomanid, the risk of abnormal liver function may increase, so attention should be paid to interactions with other anti-tuberculosis drugs, such as rifampicin, isoniazid, etc., which may have cumulative damage to the liver. Clinicians usually develop individualized monitoring frequency and intervention plans based on the patient's baseline liver function, past liver history, and combined medications to balance drug efficacy and safety.
Patients should closely observe their own conditions while taking putomanid. If they experience symptoms such as loss of appetite, nausea, yellowing of the skin or eyes, or darker urine, they should promptly inform their doctor. At the same time, maintaining a regular diet and avoiding alcohol and hepatotoxic drugs can further reduce the risk of liver function damage. Through standardized monitoring and safety management, changes in liver function under long-term use of putomanib are usually controllable, thereby ensuring the effectiveness and safety of combined anti-tuberculosis treatment.
