Does Belumosudil Interact with Midazolam?

CDI records a unknown classification for Belumosudil and Midazolam. The stored summary is: Concomitant use of REZUROCK with sensitive CYP3A substrates (e.g., midazolam) is predicted to increase CYP3A substrate exposure [see Clinical Pharmacology (12.3) ] , which may increase the risk of adverse reactions related to these substrates. Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This record was extracted from drug labeling through openFDA. NIH/NLM RxNorm is used for drug identities. The summary and severity classification are CDI's processed information, not a verbatim source quotation. Product, route, and patient circumstances matter.

How this information is prepared: CDI uses automated extraction, including AI, to summarize drug labeling from openFDA and includes separately identified curated-reference records. RxNorm helps identify medications; it does not verify interaction claims. Extracted summaries and CDI severity classifications can contain errors and are not verbatim FDA statements or independent clinical review. Maintained by CheckDrugInteractions.com. See our methodology or report a correction at support@checkdruginteractions.com.
