Pharmacological Effects and Toxicogenetic Impacts of Omeprazole: Genomic Instability and Cancer. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2020; 2020:3457890.

Abstract
Omeprazole (OME) is commonly used to treat gastrointestinal disorders. However, long-term use of OME can increase the risk of gastric cancer. We aimed to characterize the pharmacological effects of OME and to correlate its adverse effects and toxicogenetic risks to the genomic instability mechanisms and cancer-based on database reports. Thus, a search (till Aug 2019) was made in the PubMed, Scopus, and ScienceDirect with relevant keywords. Based on the study objective, we included 80 clinical reports, forty-six in vitro, and 76 in vivo studies. While controversial, the findings suggest that long-term use of OME (5 to 40 mg/kg) can induce genomic instability. On the other hand, OME-mediated protective effects are well reported and related to proton pump blockade and anti-inflammatory activity through an increase in gastric flow, anti-inflammatory markers (COX-2 and interleukins) and antiapoptotic markers (caspases and BCL-2), glycoprotein expression, and neutrophil infiltration reduction. The reported adverse and toxic effects, especially in clinical studies, were atrophic gastritis, cobalamin deficiencies, homeostasis disorders, polyp development, hepatotoxicity, cytotoxicity, and genotoxicity. This study highlights that OME may induce genomic instability and increase the risk of certain types of cancer. Therefore, adequate precautions should be taken, especially in its long-term therapeutic strategies and self-medication practices.

Akyüz M, Ata Ş, Dinç E. A chemometric optimization of method for determination of nitrosamines in gastric juices by GC-MS. J Pharm Biomed Anal 2015; 117:26-36. [PMID: 26342445 DOI: 10.1016/j.jpba.2015.08.021] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2015] [Revised: 08/14/2015] [Accepted: 08/18/2015] [Indexed: 11/26/2022]
Abstract
A chemometrically optimized isolation procedure combined with gas chromatography-mass spectrometry detection technique has been proposed for quantitative determination of trace levels of nitrosamines in gastric juice samples of patients with the gastrointestinal tract problems. The extraction conditions of each nitrosamine were optimized using regression modelling based on central composite design. The extraction conditions for all nitrosamines were selected to be 10.7 min for extraction time, 4.2 for pH and 23 for 2-propanol percentage in extraction solution. The obtained recoveries of nitrosamines ranged from 94.0 (NDMA) to 99.3 (NDPheA) %, and the precision of this method, as indicated by the relative standard deviations was within the range of 0.7 (NDPheA) and 2.6 (NDMA) %. The detection limits obtained from calculations by using GC-MS results based on S/N=3 were found within the range from 0.3 to 1.1 pg/mL. Total nitrosamine concentrations were found at the highest concentration up to 2431.12 pg/mL in cancer patients, whereas they were found at the lowest concentration down to 12.18 pg/mL in gastritis patients. The classification results of the gastric juice samples in different patient groups were very satisfactory, allowing 100% of patients to be correctly grouped. A new mathematical model has been developed allowing for the classification of gastric juices with a 93.1% success rate based on just the ratio of MNPIZ to DNPIZ. The ratio of MNPIZ to DNPIZ might be considered as a biomarker for the classification of gastric juices of patients and might act as an indicator of increased risk for stomach cancer.
