Probiotics may have an impact on drug metabolism, efficacy, and safety, according to recent research. The gut microbiota has been found to play a role in the metabolism of various drugs, including lovastatin and acetaminophen. However, the effect of probiotics on drug-metabolizing capacity is not well understood. A study showed that a specific probiotic increased the metabolic activity of acetaminophen, but had no effect on the efficacy of lovastatin. In addition, probiotics may influence drug absorption through alterations in the gut microbiota. It has also been suggested that the gut microbiota may contribute to liver damage and other organ diseases. Further research in this area could potentially improve therapy for various conditions.
