Clarifying the contraindications and high-risk medication scenarios for pazopanib is key to preventing serious adverse reactions. The following is a list of absolute contraindications and concomitant medications that need to be strictly avoided.

1、 Severe liver injury patients

1. Absolutely prohibited

Patients with severe liver function impairment are prohibited from using pazopanib, as it cannot effectively metabolize drugs and can lead to high blood drug concentrations and severe toxicity.

2. Pre medication evaluation

Liver function indicators must be tested before treatment. If baseline total bilirubin, transaminase, and other indicators significantly increase, medication should be postponed or abandoned.

3. Monitoring during treatment

During medication, liver function should be regularly checked. If there is a sharp increase in liver enzymes, the medication should be stopped immediately and medical attention should be sought.

2、 Risks associated with the combination of potent inducers of CYP3A4

1. Absolutely avoid combination use

Pazopanib should not be used in conjunction with CYP3A4 potent inducers such as rifampicin, phenytoin sodium, carbamazepine, and St. John's wort.

2. Consequences of combined use

This type of drug significantly accelerates the metabolism of pazopanib, causing a significant decrease in its blood concentration and directly weakening its anti-tumor efficacy.

3. Alternative solutions

If you need to use anti tuberculosis or anti epileptic drugs, you should discuss with your doctor to switch to alternative drugs that have no strong induction effect on CYP3A4.

3、 Other situations that need to be used with caution or avoided

1. Severe cardiovascular disease

Uncontrolled hypertension, severe arrhythmia, or recent myocardial infarction patients should not use it.

2. Recent active bleeding or thrombosis

Individuals with a tendency towards bleeding or a history of thrombotic events should carefully assess their risk.

3. Pregnancy and lactation period

Animal studies have shown fetal toxicity and the drug may enter breast milk, therefore it is contraindicated during pregnancy, and breastfeeding or medication should be stopped during lactation.
