INTRODUCTION: CYP2D6 and CYP2C19 functional status as defined by genotype is modulated by phenoconversion (PC) due to pharmacokinetic interactions. As of today, there is no data on the effect size of PC for CYP2C19 functional status. The primary aim of this study was to investigate the impact of PC on CYP2C19 functional status. METHODS: Two patient cohorts (total n=316; 44.2±15.4 years) were investigated for the functional enzyme status of CYP2C19 applying two different correction methods (PCBousman , PCHahn&Roll ) as well as serum concentration and metabolite-to-parent ratio of venlafaxine, amitriptyline, mirtazapine, sertraline, escitalopram, risperidone, and quetiapine...

BACKGROUND: s and Aims: Los Angeles (LA) grade C/D esophagitis is a severe manifestation of GERD that require active treatment and close follow-up. Potassium competitive acid blockers (P-CABs) are promising alternatives to proton-pump inhibitors (PPIs). We aimed to compare the efficacy and safety of P-CABs and PPIs in healing Grade C/D esophagitis to aid clinical decision-making. METHODS: A systematic literature search was performed using PubMed, MEDLINE, Cochrane Central Register of Controlled Trials...

INTRODUCTION: In Chile, more than 70% of adults are infected by Helicobacter pylori. Clarithromycin should not be used in any regimen if there is >15% resistance to this antibiotic, being greater than 26% in our population. In this scenario, the effectiveness of triple therapy (proton pump inhibitor [PPI], clarithromycin, amoxicillin) was only 63.8%. AIM: To evaluate the eradication rate and safety of dual therapy (esomeprazole and amoxicillin) in high doses, through a prospective, observational, and descriptive study...

OBJECTIVES: We aimed to explore the efficacy and safety of tailored therapy guided by genotypic resistance in the first-line treatment of Helicobacter pylori (H. pylori) infection in treatment-naive patients. METHODS: Gastric mucosal specimens were taken during gastroscopy, and main mutations of clarithromycin- and levofloxacin-resistant genes were detected by polymerase chain reaction (PCR). Sensitive antibiotics were selected individually for treating H. pylori infection with tailored bismuth-containing quadruple therapy (BQT) consisting of esomeprazole 20 mg twice daily, bismuth potassium citrate 220 mg twice daily, amoxicillin 1 g twice daily, and clarithromycin 500 mg twice daily, or levofloxacin 500 mg once daily, or metronidazole 400 mg four times daily...

Proton pump inhibitors (PPIs) have recently been reported to be linked with nephrotoxicity. PPIs are metabolized mainly or partly by cytochrome P450 2C19 (CYP2C19). However, the relationship between CYP2C19 genetic polymorphism and PPI-induced nephrotoxicity is unclear. In this study, we aimed to analyze the association between the time of occurrence of renal injury by PPIs, including lansoprazole, esomeprazole, rabeprazole, and vonoprazan, and CYP2C19 metabolizer status classified by CYP2C19 genotypes. Patients prescribed PPIs were reviewed in this retrospective cohort study...

BACKGROUND AND AIM: Fexuprazan is a novel potassium-competitive acid blocker (P-CAB). This study aimed to explore the noninferior efficacy and safety of fexuprazan to esomeprazole in treating erosive esophagitis (EE). METHODS: This was a phase III, randomized, double-blind multicenter study. Patients with endoscopically confirmed EE were randomized to receive fexuprazan 40 mg or esomeprazole 40 mg once a daily for 4-8 weeks. The healing rates of EE, symptom response, GERD-health-related quality life (GERD-HRQL), and treatment-emergent adverse events (TEAEs) were compared between fexuprazan group and esomeprazole group...

In recent times, the methods used to evaluate gastric ulcer healing worldwide have been based on visual examinations and estimating ulcer dimensions in experimental animals. In this study, the protective effect of rhodanine and 2,4-thiazolidinediones scaffolds compared to esomeprazole was investigated in an ethanol model of stomach ulcers in rats. Pretreatment with experimental treatments or esomeprazole prevented the development of ethanol-induced gastric ulcers. The severity of the lesions and injuries was significantly lower than that of vehicle (10% Tween 80) treated rats...

INTRODUCTION: Proton pump inhibitors (PPIs) constitute a widely utilized pharmaceutical class, frequently associated with notable instances of therapeutic inappropriateness. Such patterns of misuse not only contribute to elevated healthcare expenditure, but may also exacerbate clinical conditions in certain patients. METHODS: A comprehensive analysis was conducted between 2019 and 2023 to assess all prescriptions dispensed using the Anatomical, Therapeutic and Chemical (ATC) classification system, which allowed trends among primary PPIs to be visualized...

BACKGROUND: Treating Helicobacter pylori is becoming increasingly difficult with the development of bacterial resistance to many established treatment regimens.

BACKGROUND: Proton-pump inhibitors (PPIs) are the most effective drugs for treating acid-related disorders. However, once-daily dosing with conventional PPIs fail to fully control acid secretion over 24 h. This study aimed to compare the efficacy and safety of HIP1601 (dual delayed-release esomeprazole) and HGP1705 (delayed-release esomeprazole) in patients with erosive esophagitis (EE). METHODS: We enrolled 213 patients with EE randomized in a 1:1 ratio to receive 40 mg HIP1601 (n = 107) or HGP1705 (n = 106) once daily for 4 or 8 weeks...

BACKGROUND AND AIMS: Acid-suppressive drugs (ASDs) are widely used in many gastric acid-associated diseases. Nocturnal acid breakthrough has been a common problem of many ASDs, such as proton-pump inhibitors (PPIs) and H2 -receptor antagonists (H2RAs). Potassium-competitive acid blockers (P-CABs) are expected to solve this continuing conundrum. This article examined major ASDs and compared them with placebo in terms of nocturnal acid-inhibitory effects, using a network meta-analysis of randomized controlled trials (RCTs)...

OBJECTIVE: Peptic ulcer (PU) and hypertension are chronic diseases affecting up to 10% and 30% of the adult population worldwide. Most of these patients will require treatment with a combination of antihypertensive medicines, which have adverse effects on the body's different organs. This study specifically focused on antihypertensive multi-drug induced PU disease and disturbance of liver function. MATERIALS AND METHODS: During a 14-day oral administration of antihypertensive drugs, Cilnidipine (1 mg/kg), Rosuvastatin (1 mg/kg), Bisoprolol (0...

As a widely used antidepressant that works by inhibiting the reuptake of serotonin, sertraline exerts an antidepressant effect depending on its concentration in the brain, which might be limited by the blood-brain barrier (BBB). It is highly possible to combine proton pump inhibitors (PPIs) with sertraline in clinical trials. Nevertheless, the role played by PPIs in regulating the transport of sertraline across the BBB remains unclear. Here, the impact of PPIs on the distribution of sertraline in the brain and the mechanisms involved were investigated...
