Psychotropic Drugs and Microbiota - Important and Little Known Interaction

Dr. Łoniewsk Targeting Microbiota 2019

During the 7th World Congress on Targeting Microbiota scheduled on October 10-11, 2019 at the ParkInn Hotel - Krakow, Poland, Dr. Igor Loniewski from Pomeranian Medical University, Poland will give a presentation entitled "Psychotropic Drugs and Microbiota - Important and Little Known Interaction".

Summary of presentation: "Alterations in intestinal microbiota have been associated with the use of antidepressants. Antidepressants differ in mechanisms of their antibacterial activity; for example, they affect cellular respiration, whereby Monoamine Oxidase Inhibitors (MAOIs) can disturb bacterial cell-wall synthesis. Tricyclic antidepressants (TCAs) inhibit DNA gyrase activity and plasmid DNA replication. Selective serotonin reuptake inhibitors (SSRIs) inhibit bacterial efflux pumps. Escitalopram has also antibacterial activity, moreover it was also shown that a six-week escitalopram treatment in a psychiatric hospital setting resulted in increased alpha biodiversity in fecal microbiota Antipsychotic treatment-related microbiome alterations potentially result in body weight gain and metabolic disturbances. Inflammation and resting metabolic rate suppression seem to play crucial roles in the development of metabolic disorders. However in our study we found that the microbiota of schizophrenia patients is highly individual but can be divided into different taxonomical and functional clusters and it does not change following six weeks of olanzapine therapy. Microbiota did not affect either the weight gain observed in women or the effectiveness of olanzapine therapy."
