The gut microbiome preserves biological fingerprints of previously used medications for extended periods after treatment ends, a new study suggests.
Microbial communities in the digestive tract can shift dramatically when people take antibiotics and other drugs.
Researchers found that some of those shifts persist long after patients stop taking the medications.
The retained signatures may influence digestion, immunity and susceptibility to certain conditions.
Scientists analyzed microbiome samples collected before, during and after drug courses in study participants.
They identified microbial patterns uniquely associated with specific prior medication exposures.
The findings raise questions about how past prescriptions affect current health even when drugs are no longer active.
Clinicians may eventually use microbiome profiling to understand a patient’s medication history.
Researchers have not yet determined how long all medication-related signatures remain detectable.
The work adds to evidence that the microbiome acts as a long-term record of environmental and medical exposures.
