Clostridium difficile infection (CDI) remains a devastating cause of hospital-acquired diarrhea. Treatment modalities have centered traditionally on two antibiotics, metronidazole and oral vancomycin. Both drugs, however, have been associated with variable relapse rates up to 20%. ⋯ We believe that antibiotic selection for the treatment of patients with any infectious disease must account for the possibility of subsequent severe CDI. We posit 'upstream' antibiotic selection will prevent 'downstream' CDI and potentially ameliorate deficiencies in infection prevention practices. Formal studies evaluating such an endpoint would be useful in this era of dangerous CDI.

There is no denying that opioids are the most important analgesic drugs which are widely used in clinical situations. Still, prolonged administration of these drugs can cause to reduce their analgesic efficacy due to the development of tolerance. ⋯ As studies show, over-activity in cyclo-oxygenase pathways and production of prostaglandins due to long-term exposures of opioid have a critical role in the development of tolerance to antinociceptive effect of opioid, hyperalgesia, and opioid dependence. The present study aims at suggesting the hypothesis that through blending a non-steroid anti-inflammatory drug with opioid actively causes reduction in unwanted effects of opioid i.e. by inhibition of opioid-induced cyclo-oxygenase overactivity whereas it is well-known that the combination therapy via reducing opioid dosage reduces the unwanted effects.
