Does poor liver function increase blood levels of drugs such as clozapine through decreased ability to metabalise the drug?

Yes, poor liver function can increase blood levels of drugs like clozapine due to the liver's reduced ability to metabolize these medications. The liver is primarily responsible for drug metabolism, and impaired function can lead to decreased clearance of the drug from the bloodstream. This can result in elevated drug levels, increasing the risk of side effects and toxicity. Therefore, monitoring and dosage adjustments may be necessary for individuals with liver dysfunction.
