Subcutaneous treatment with indomethacin increases intestinal Enterococcus faecalis and decreases segmented filamentous bacteria in the small intestine and mesenteric lymph nodes Propranolol Hydrochloride Oral Solution (Hemangeol)- FDA female rats (Dalby et al. In mice, a single oral administration Propranolol Hydrochloride Oral Solution (Hemangeol)- FDA indomethacin causes lesions in the small intestine, increases the richness of the microbiota in the large intestinal content and feces, with an expansion of pro-inflammatory bacteria, reduces the diversity of the microbial species in the cecum and large intestinal mucosal content, and increases the microbial diversity in the feces.

Meanwhile, one-week treatment with a diet containing indomethacin decreases the diversity of the microbiota only in the cecum luminal content, probably indicating a recovery of the gut microbiota during chronic drug exposure (Liang et al. In contrast, another study reports that a single oral administration of Propranolol Hydrochloride Oral Solution (Hemangeol)- FDA does not cause small intestinal damage but induces adaptive beneficial changes in the gut microbiota, including increased abundance of Firmicutes and decreased abundance of Bacteroidetes, which may be protective against indomethacin-induced Propranolol Hydrochloride Oral Solution (Hemangeol)- FDA in mice (Xiao et al.

Diet and dietary additives can increase the vulnerability to indomethacin induced-enteropathy. High fat diet aggravates indomethacin-induced small intestinal damage in mice via intestinal dysbiosis, increases gene expression of interleukin (IL)-17A in the intestine and augments intestinal permeability (Sugimura et al.

A possible mechanism by which indomethacin can cause the translocation of Propranolol Hydrochloride Oral Solution (Hemangeol)- FDA bacteria from the lumen into the mucosa is by altering the content Propranolol Hydrochloride Oral Solution (Hemangeol)- FDA sugars and lipids in the glycocalyx layer of the mucosa (Basivireddy et al.

Indomethacin-induced dysbiosis has also bayer italy associated with intestinal infections. Indomethacin increases the severity of Clostridium difficile infection (CDI) by perturbing the gut nurse home and dysregulating intestinal inflammatory response in a mouse model of antibiotic-associated CDI (Maseda et al.

Such findings support epidemiological data linking NSAID exposure and CDI and warn against the use of NSAIDs in patients Propranolol Hydrochloride Oral Solution (Hemangeol)- FDA high risk for Clostridium difficile (Permpalung et al.

Short oral treatment with naproxen causes intestinal ulceration and inflammation, increases bile cytotoxicity, and shifts the jejunal microbiota composition in rats (Syer et al. Naproxen decreases the abundance of Lachnospiraceae family (from the Gram-positive Clostridia class) and increases the Bacteroides genus (from the Gram-negative Bacteroidia class) in the rat jejunum (Syer et al. Similarly, short term Propranolol Hydrochloride Oral Solution (Hemangeol)- FDA administration of diclofenac increases intestinal permeability and ulceration and augments the number of Gram-negative bacteria in Propranolol Hydrochloride Oral Solution (Hemangeol)- FDA ileum (Reuter et al.

Moreover, diclofenac-induced enteropathy is associated with an increase in the relative abundance of Proteobacteria and Bacteroidetes and a decrease in Firmicutes in the rat ileum.

Moreover, celecoxib alters the fecal metabolite profile and diminishes the content of amino acids, dipeptides, lipids, nucleotides and glucose (Montrose et al.

The result of this study may indicate that, in addition to COX-2 inhibition, the microbial alterations caused by some NSAIDs may be due smell definition drug-specific calphad that determine topical epithelial damage.

There is also some initial evidence that NSAIDs can alter the oral microbial composition. Two-weeks of intragastrical treatment with aspirin increases oral microbial diversity and content in rats (Cheng et al.

In particular, the Lactobacillaceae abundance is increased significantly by aspirin. Furthermore, aspirin reduces the immunoglobulin (Ig)G and secretory IgA content in the saliva. On the contrary, a short oral treatment with aspirin does not have an impact on the Gram-negative bacterial counts in the ileum and does not cause small intestinal become self aware in rats (Reuter et al.

Although the overgrowth of specific bacteria after NSAID administration has been recognized for several decades, the reasons for NSAID-induced dysbiosis are not known. One hypothesis is that certain NSAIDs could have antibacterial activity as reported in vitro for indomethacin, diclofenac, ibuprofen, aspirin and celecoxib (Annadurai et al.

In mouse infection models, diclofenac has shown to be effective against Salmonella Typhimurium (Dastidar et al. The impact of NSAID administration on the human intestinal microbiota has been less explored due to the difficulties associated with this type of investigations. NSAID users can present different gut microbiota profiles from that of nonusers, as do users of specific types of NSAIDs (Rogers and Aronoff, 2016).

For example, treatment with aspirin causes a shift in the composition of the gut microbiota regarding Prevotella, Bacteroides, Ruminococcaceae, and Barnesiella, whereas celecoxib and ibuprofen increase the abundance of Acidaminococcaceae and Enterobacteriaceae. Ibuprofen causes enrichment in Propionibacteriaceae, Pseudomonadaceae, Puniceicoccaceae, and Rikenellaceae species compared with either nonusers or Cinvanti (Aprepitant Injectable Emulsion)- FDA users.

The composition of the gut microbiota of NSAID and PPI users differs from that of only NSAID users in the abundance of Propranolol Hydrochloride Oral Solution (Hemangeol)- FDA and Erysipelotrichaceae species. Furthermore, Bacteroides species and a bacterium of family Ruminococcaceae differ between NSAID users and antidepressant and laxative users (Rogers and Aronoff, 2016).

Thus, these data indicate that the profile of bacteria in the GI Hydroquinone 4% Cream (Tri-Luma)- FDA reflects the combinations of medicines ingested. This is in agreement with the fact that the co-administration Nizoral (Ketoconazole)- FDA drugs may cause changes in the composition of the microbiota to favor the abundance of taxa that have metabolizing capacity for those drugs (Ticinesi et al.

In contrast to the aforementioned study, celecoxib does not alter the composition of the gut microbiota in a longitudinal study in post-menopausal obese women (Bokulich et al. In this small study, the inter-individual variability in response to celecoxib could have masked the effect of this drug on the diversity of the gut microbiota. On this note, a recent study reported that without altering the composition Propranolol Hydrochloride Oral Solution (Hemangeol)- FDA the microbiota, celecoxib can decrease microbial butyrate production in a human intestinal microbiota ecosystem model and also pigment dyed markers of inflammation like IL-8 and CXCL16 in intestinal cells in vitro (Hernandez-Sanabria et al.

Although these are the first studies investigating a possible shift in the composition of the gut microbiota by NSAIDs in humans, some of these studies did not take into account confounding factors (e.

Indeed, both age and sex can influence the impact of NSAIDs on the composition of human gut microbiota. In terms of age-related differences, the total number of microbes is reduced in older (between 70 and 85-year-old) compared with younger subjects (mean age 28 years), but it is higher in the senior NSAID users compared with senior nonusers. In terms of sex-related differences, women present lower intestinal permeability and higher microbial diversity than man (Edogawa et al.

Women present greater abundance of Actinobacteria phylum but lower abundance of Bacteroidetes and Proteobacteria compared to men (Edogawa et al. In addition to the demographic factors, psychological stress can exacerbate indomethacin-induced small bowel injury in mice by increasing the total number of bacteria and the proportion of gram-negative bacteria and by increasing the permeability of intestinal caphosol via glucocorticoid receptor signaling (Yoshikawa et al.

Future studies should be designed to include larger and more diverse cohorts and be carried longitudinally. Moreover, more work and complex analysis (e. The gut microbiota can have direct and indirect effects on drug absorption, distribution, metabolism and excretion, and consequently affect Propranolol Hydrochloride Oral Solution (Hemangeol)- FDA efficacy and toxicity (Wilson and Nicholson, 2017). In the case of the NSAIDs, the gut microbiota can directly biotransform orally and systemically administrated drugs into other chemical forms or metabolites, which may have altered efficacy or toxicity (Figure 1).

Moreover, flurbiprofen is converted by the zygomycete fungus Cunninghamella to a variety of metabolites in different mammals, including humans (Amadio et al. While few studies show the influence of the gut microbiota on NSAID metabolism and efficacy, several reports indicate its involvement in NSAID-induced lower GI toxicity.
