Department of Preventive Medicine, Seoul National University College of Medicine, Seoul, Korea.
Objectives: This study was performed to evaluate the utilization patterns of acid suppressants following the withdrawal of ranitidine in Korea.
Methods: Health Insurance Review & Assessment Service (HIRA) data from January 2016 to May 2023 were utilized to assess the usage of histamine H2 receptor antagonists (H2RAs) and proton pump inhibitors (PPIs) for acid-related diseases. Drug utilization was calculated for each agent based on the defined daily dose (DDD).

This study investigated the potential genotoxic and carcinogenic effects of N-nitrosodimethylamine (NDMA), a hazardous compound found in ranitidine formulations that are used to treat excessive stomach acid. The study first examined the effects of NDMA-contaminated ranitidine formulation on Allium cepa root growth and mitotic activity. The results demonstrated dose-dependent decreases in both root growth and mitotic index indicating genotoxicity and cell division disruption.

Gastric ulcer (GU) is the most common health concern that occurs due to an imbalance between gastric protective mucosal and aggressive factors. Ethanol-induced GU in animal models resembles the pathophysiology of human ulcers. Natural products with fewer side effects are highly requested to attenuate their GU effects.

Although the cellular prion protein (PrP) has been evolutionarily conserved, the role of this protein remains elusive. Recent evidence indicates that PrP may be involved in neuroinflammation and the immune response in the brain, and its expression may be modified via various mechanisms. Histamine is a proinflammatory mediator and neurotransmitter that stimulates numerous cells via interactions with histamine receptors 1-4 (HRH1-4).
