BACKGROUND: The inhibition of gastric acid secretion with ranitidine is frequently prescribed off-label to newborns admitted to neonatal intensive care units (NICU). Some studies show that the use of inhibitors of gastric acid secretion (IGAS) may predispose to infections and necrotising enterocolitis (NEC), but there are few data to confirm this association. This study aimed to compare the rates of neonatal infections and NEC among preterm infants (<37 weeks gestation) hospitalised in a NICU exposed or not to treatment with ranitidine...

There is a need to find/discover novel leads to treat complex and/or multi-factorial-pathogenic disease(s) like Nonsteroidal anti-inflammatory drugs (NSAID)-induced gastroenteropathy or gastrointestinal (GI) toxicity as it has emerged as an important medical and socioeconomic problem. There is no approved therapeutic strategy to prevent NSAID-induced enteropathic damage and highly effective gastro-protective drugs such as ranitidine hydrochloride (RAN) exacerbate it. In this purview, the multi target drug discovery approach (MTDD), combination approach and hit to lead strategies based on the foundation of ethnopharmacology and/or reverse pharmacology holds strong potential...

In this article we compare the efficacy of different pharmacological agents (ranitidine, and omeprazole) to support phage transit from stomach to distal portions of the gastrointestinal tract in rats. We show that a temporal modification of environment in the animal stomach may protect Twort-like therapeutic antistaphylococcal phage A5/80 (from bacteriophage collection of the Hirszfeld Institute of Immunology and Experimental Therapy PAS in Wroclaw, Poland) from the inactivation by gastric juice effectively enough to enable a significant fraction of orally administered A5/80 to pass to the intestine...
