ABSTRACT
Psychiatric symptoms are frequently found in patients with cancer and often require specific pharmacological treatment. Depression seems to be the most common psychiatric disorder followed by adjustment disorders, anxiety, and delirium. Psychiatric comorbidities are responsible for worse quality of life and low adherence to anticancer treatment. Many different psychiatric drugs are beneficial, but there are increasing risks of drug-drug interactions (DDIs) with anticancer drugs. We conducted a PRISMA-compliant systematic review (PROSPERO registered) on drug-drug interactions between psychiatric and anticancer medications, using predefined search terms in electronic databases and specialized interaction software. Only six studies met the predefined inclusion criteria, confirming a significant lack of evidence on this topic. The available studies were often limited by small sample sizes, inadequate controls, or insufficient assessment of drug interactions. Our expanded search in drug interaction software allowed us to cross-reference results and identify clinically relevant interactions. The aim of this paper is to collect and summarize in a user-friendly format the most significant DDIs and to show unfavorable and potentially dangerous combination of drugs.
