Antibiotic‐induced decrease of bacterial load in guinea pig intestine reduces α2‐adrenoceptor expression and activity in peristaltic motor inhibition

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose The use of analgosedatives in critically ill patients carries the risk of impairing gastrointestinal (GI) propulsion and could thereby lead to sepsis. The gut microbiota can influence GI motility, but whether GI microbial dysbiosis modifies GI peristalsis impairment by analgosedative drugs has not yet been analysed. This question
