Coffee consumption can significantly alter the absorption, distribution, metabolism, and excretion of many drugs, leading to varied therapeutic responses.
The methodology involved a comprehensive review of research findings, clinical case reports, and expert panels from various reputable sources. These sources ranged from dedicated scientific databases such as Scopus, PubMed, Hindawi, OVID, Embase, and the Cochrane Library, to the broader database of Google Scholar, and the research-intensive Web of Science.
In terms of results, it was found that the simultaneous consumption of coffee significantly impacts the pharmacokinetics of many drugs. This can result in a heightened therapeutic response, a failure of the therapeutic response, or even toxic reactions. As a result, it's suggested that the concurrent consumption of coffee and medications that interact significantly with coffee should be avoided. It's advised that there should be an appropriate time gap between drug intake and coffee based upon the specific properties of the drug. Both pharmacists and clinicians should be aware of these potential risks of drug-coffee interaction.
