Summary
Barbiturates induce CYP3A4, the main metabolic pathway of pazopanib, and may lower its exposure and antitumor efficacy. Pazopanib labeling advises avoiding strong CYP3A4 inducers.
What this interaction means in plain words
Amobarbital and Pazopanib can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Amobarbital belongs to Central Nervous System; Pazopanib belongs to Oncology.
Why it happens
CYP3A4 induction by amobarbital increases pazopanib clearance.
What to do
Avoid combination where possible and use a non-inducing alternative. If unavoidable, monitor tumor response and toxicity closely.
