Chapter 1: The Gut Microbiome and Medications

Can the bacteria residing in your gut hinder the effectiveness of your medications? The human gut is home to trillions of microorganisms, including bacteria, fungi, archaea, and viruses. Together, these entities form the gut microbiome, a complex ecosystem that plays a critical role in our overall health.

Researchers are continually uncovering how these microorganisms influence various aspects of our physiology, behavior, and metabolism. A groundbreaking study has revealed that gut bacteria not only interact with medications but also accumulate them, rather than merely breaking them down. This accumulation could have significant implications for both our body’s physiology and the microbiome itself.

The study, published on August 10, 2021, in the esteemed journal Nature, involved the cultivation of 25 common gut bacteria and their interaction with 15 orally administered drugs. While interactions between drugs and the gut microbiome are already well-established, this research uncovered a new type of interaction.

Dr. Kiran Patil, a co-author of the study from the MRC Toxicology Unit at the University of Cambridge, noted, “It was surprising that the majority of the new interactions we saw between bacteria and drugs were the drugs accumulating in the bacteria.” Instead of metabolizing or altering the drugs, the bacteria “swallowed” these substances, leading to their accumulation.

This phenomenon has the potential to modify the function of common gut microbes. When drugs accumulate within bacterial cells, they can bind to various proteins and enzymes. For example, the widely used antidepressant duloxetine alters the molecules produced by one type of gut microbe, which in turn affects other bacteria that rely on these molecules for nourishment.

Understanding the microbiome is essential when prescribing or evaluating the effects of new oral medications. This insight may explain the variability in treatment responses among individuals, particularly regarding antidepressants, as well as the diverse side effects experienced by different patients.
