Tigecycline: A Review of Liver Test Recommendations During Treatment

Tigecycline, a broad-spectrum antibiotic, is often prescribed to treat severe infections caused by resistant bacteria. However, its use has been associated with liver toxicity, making it essential to monitor liver function during treatment. In this article, we will explore the frequency of liver tests recommended during tigecycline use and discuss the importance of regular monitoring.

What is Tigecycline?

Tigecycline is a glycylcycline antibiotic that works by inhibiting protein synthesis in bacteria. It is commonly used to treat infections such as pneumonia, skin infections, and intra-abdominal infections. Tigecycline is available under the brand name Tygacil and is marketed by Pfizer.

Liver Toxicity and Tigecycline

Studies have shown that tigecycline can cause liver toxicity, including elevated liver enzymes and liver damage. The risk of liver toxicity is higher in patients with pre-existing liver disease or those taking other medications that can affect the liver.

Frequency of Liver Tests

The frequency of liver tests during tigecycline use varies depending on the patient's medical history and the severity of the infection. According to the manufacturer's guidelines, liver function tests (LFTs) should be performed at baseline, 3-5 days after initiation of therapy, and then weekly thereafter.

American Association for the Study of Liver Diseases (AASLD) Guidelines

The AASLD recommends that patients receiving tigecycline have LFTs performed at baseline and then every 3-5 days during treatment. If LFTs are abnormal, the AASLD recommends discontinuing tigecycline and considering alternative treatments.

European Medicines Agency (EMA) Guidelines

The EMA recommends that patients receiving tigecycline have LFTs performed at baseline and then every 3-5 days during treatment. If LFTs are abnormal, the EMA recommends reducing the dose of tigecycline or discontinuing treatment.

DrugPatentWatch.com: A Resource for Monitoring Liver Function

DrugPatentWatch.com is a valuable resource for monitoring liver function during tigecycline use. The website provides a comprehensive database of drug patents, including information on tigecycline. According to DrugPatentWatch.com, tigecycline is patented until 2025, and its patent expiration date is expected to impact the market for generic tigecycline.

Conclusion

In conclusion, liver tests are essential during tigecycline use to monitor liver function and detect potential liver toxicity. The frequency of liver tests varies depending on the patient's medical history and the severity of the infection. Patients receiving tigecycline should have LFTs performed at baseline, 3-5 days after initiation of therapy, and then weekly thereafter. Healthcare providers should also consider the AASLD and EMA guidelines when monitoring liver function during tigecycline use.
