Assessment of omeprazole and famotidine effects on the pharmacokinetics of tacrolimus in patients following kidney transplant-randomized controlled trial. Front Pharmacol 2024; 15:1352323. [PMID: 38638867 PMCID: PMC11024357 DOI: 10.3389/fphar.2024.1352323] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Accepted: 03/21/2024] [Indexed: 04/20/2024] Open
Abstract
Tacrolimus is metabolized in the liver with the participation of the CYP3A4 and CYP3A5 enzymes. Proton pump inhibitors are used in kidney transplant patients to prevent duodenal and gastric ulcer disease due to glucocorticoids. Omeprazole, unlike famotidine, is a substrate and inhibitor of the enzymes CYP2C19, CYP3A4, CYP3A5. The aim of this study was to compare the impact of omeprazole and famotidine on the pharmacokinetics of tacrolimus. A randomized, non-blinded study involving 22 stabilized adult kidney transplant patients was conducted. Patients received the standard triple immunosuppression regimen and omeprazole 20 mg (n = 10) or famotidine 20 mg (n = 12). The study material consisted of blood samples in which tacrolimus concentrations were determined using the Chemiluminescent Microparticle Immuno Assay method. A single administration of omeprazole increased tacrolimus concentrations at 2 h (day 2) = 11.90 ± 1.59 ng/mL vs. 2 h (day 1 - no omeprazole administration) = 9.40 ± 0.79 ng/mL (p = 0.0443). AUC0-6 amounted to 63.07 ± 19.46 ng × h/mL (day 2) vs. 54.23 ± 10.48 ng × h/mL (day 1), (p = 0.0295). AUC2-6 amounted to 44.32 ± 11.51 ng × h/mL (day 2) vs. 38.68 ± 7.70 ng × h/mL (day 1), (p = 0.0130). Conversely, no significant changes in values of pharmacokinetic parameters were observed for famotidine. Omeprazole significantly increases blood exposure of tacrolimus. The administration of famotidine instead of omeprazole seems safer for patients following kidney transplantation. Clinical Trial Registration: clinicaltrials.gov, identifier NCT05061303.

Abstract
INTRODUCTION Acid suppression medications, such as proton-pump inhibitors (PPIs) and histamine-2 receptor antagonists, are commonly prescribed for the treatment of gastroesophageal reflux disease and other gastrointestinal disorders. However, concerns regarding potential long-term side effects are brought up by the overuse of PPIs. This study aimed to investigate the relationship between PPI usage, allergy, and asthma in the general US population. METHODS Data of individuals aged ≥20 years who had information on PPI use and questionnaires on allergy and asthma in the US National Health and Nutrition Examination Survey (NHANES) 2005-2006 were analyzed. Univariate and multivariable logistic regression analyses were performed to determine the associations between PPI use, prevalent allergy, and asthma. RESULTS A total of 4,481 participants (representing 198,543,007 US individuals after weighting) were included in the analyses. PPI use was not significantly associated with the presence of allergy or asthma in the general study population after adjustment. However, in females without steroid exposure, PPI use was significantly associated with increased odds of allergy (adjusted odds ratio [aOR] = 1.69, 95% confidence interval [CI]: 1.002-2.86), among which esomeprazole use was significantly associated with increased odds of allergy (aOR = 2.68, 95% CI: 1.30-5.54) and lansoprazole with increased odds of asthma (aOR = 3.44, 95% CI: 1.50-7.87) as compared to no PPI use. Duration of PPI use was not significantly associated with allergy or asthma. CONCLUSIONS In US women without steroid exposure, PPI use is associated with increased likelihood of prevalent allergy and asthma.

Abstract
Tacrolimus is a calcineurin inhibitor used to prevent rejection in allogenic solid organ transplant recipients, which is metabolized in the liver with cytochrome P450 isoforms 3A4 and 3A5 (CYP3A4, CYP3A5). In turn, proton pump inhibitors (PPIs), such as Omeprazole - a substrate and inhibitor of CYP2C19 and CYP3A4 enzymes - are administered to kidney transplant patients in order to prevent duodenal and gastric ulcer disease, associated with the glucocorticoid treatment. Simultaneous administration of both drugs in renal patients has the potential to trigger drug interactions. In fact, there are several mechanisms which may impact the pharmacokinetics of tacrolimus. Inhibition of the CYP2C19 isoform may suppress the metabolism of omeprazole, subsequently altering its metabolic pathway to be metabolized by the CYP3A4 enzyme in order to maintain adequate biotransformation. Therefore, the competition for CYP3A4 may affect the metabolism of tacrolimus and result in its increased plasma concentrations, as well as in adverse reactions. Another mechanism has been related to the genetic polymorphism of the CYP2C19 isoform. Since all these interactions may lead to dysfunctions of the transplanted kidney, it seems significant to eliminate their consequences, for instance via the administration of drugs which are neither substrates, nor inhibitors of the CYP3A4 enzyme. Finally, the nephrotoxic effect of omeprazole should also be accounted for. Bearing in mind the aforementioned observations, the aim of the presented paper was to review the available studies addressing the effect of omeprazole on the pharmacokinetics of tacrolimus.

Abstract
Background Esomeprazole, a potent proton pump inhibitor (PPI), is widely used for the prevention of stress ulcers in intensive care unit (ICU) patients. Objective This study investigates the pharmacokinetics (PK) of esomeprazole in critically ill patients. Methods The study included eligible adult ICU patients who received endotracheal intubation assisted mechanical ventilation for more than 48 h and had at least an extra risk factor for stress ulcers. All enrolled patients received once-daily intravenous (IV) esomeprazole 40 mg. After the first dose of esomeprazole was administrated, serial blood samples were collected at 3, 5, 15, 30 min and 1, 2, 4, 6, 8, and 10 h. The total sample concentrations of esomeprazole were measured by UPLC-MS/MS. Esomeprazole PK parameters were analyzed using noncompartmental analysis. Results A total of 30 patients were evaluable. Mean age and body mass index (BMI) were 61.97 years and 23.14. PK sampling on the first dose resulted in the following median (IQR) parameters: AUC0−∞ 8.06 (6.65–9.47) mg·h/L; MRT0−∞ 4.70 (3.89–5.51) h; t1/2 3.29 (2.7–3.87) h; V 24.89 (22.09–27.69) L; CL 6.13 (5.01–7.26) L/h; and Cmax 2.56 (2.30–2.82) mg/L. Conclusions According to the label of esomeprazole, our study showed different esomeprazole PK parameters in ICU patients compared with healthy volunteers. Esomeprazole has unique pharmacokinetic parameters in critically ill patients.

Proton pump inhibitors interfere with the anti-tumor potency of RC48ADC. Toxicol In Vitro 2021; 79:105292. [PMID: 34871754 DOI: 10.1016/j.tiv.2021.105292] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Revised: 11/13/2021] [Accepted: 11/30/2021] [Indexed: 11/23/2022]
Abstract
Antibody-drug conjugates (ADCs) are a promising modality for cancers, but the interaction between them and proton pump inhibitors (PPIs), the common adjuvant drugs for cancer treatment, has not been understood. Here, the interactions between PPIs and RC48ADC, a novel HER2-targeting ADC, were quantified in vitro. CCK-8 assay showed that RC48ADC displayed a significant inhibitory effect on the proliferation of SK-BR-3, NCI-N87 and SK-OV-3 cells with the IC50 values of 4.91 ± 1.15 ng/mL, 14.54 ± 0.85 ng/mL and 11.28 ± 0.68 ng/mL respectively. PPIs alone had no significant anti-tumor effect in the dose range of 1.37-1000 ng/mL. When used together, PPIs inhibited the anti-tumor activity of RC48ADC in a dose-dependent manner. And 1000 ng/mL (~Cmax) PPIs significantly recovered RC48ADC-inhibited cell proliferation by (32.85 ± 2.81) % (p < 0.05). However, cimetidine, a non-PPIs gastric acid secretion inhibitor, had no significant inhibitory effect on RC48ADC. Furthermore, omeprazole, rather than cimetidine, significantly reduced the activity of vacuolar H+-ATPase and Cathepsin B compared with the control cells. These results, if confirmed in vivo, indicate that PPIs are antagonists of RC48ADC, even all ADCs, appearing to be due to inhibition of vacuolar H+-ATPase activity. Moreover, cimetidine combined with ADCs instead of PPIs can prevent an adverse drug interaction.

Abstract
WHAT IS KNOWN AND OBJECTIVE Esomeprazole, the S-isomer of omeprazole, is a proton pump inhibitor which has been approved by over 125 countries, also known as NEXIUM® . Esomeprazole was developed to provide further improvement on efficacy for acid-related diseases with higher systemic bioavailability due to the less first-pass metabolism and lower plasma clearance. Esomeprazole is primarily metabolized by CYP2C19. Approximately <1% of Caucasians and 5%-10% of Asians have absent CYP2C19 enzyme activity. Although the influence of various CYP2C19 phenotypes on esomeprazole pharmacokinetics has been studied, this is the first report in the Japanese population where 27 low CYP2C19 metabolizers were included. METHODS In this study, a population PK model describing the PK of esomeprazole was developed to understand the difference of CYP2C19 phenotypes on clearance in the Japanese population. The model quantitatively assessed the influence of CYP2C19 phenotype on esomeprazole PK in healthy Japanese male subjects after receiving repeated oral dosing. The inhibition mechanism of esomeprazole on CYP2C19 activity was also included in the model. RESULTS AND DISCUSSION CYP2C19 phenotype and dose were found as statistically significant covariates on esomeprazole clearance. The apparent clearance at 10-mg dose was 17.32, 9.77 and 7.37 (L/h) for homozygous extensive metabolizer, heterozygous extensive metabolizer and poor metabolizer subjects, respectively. And the apparent clearance decreased as dose increased. WHAT IS NEW AND CONCLUSION The established population PK model well described the esomeprazole PK and model-predicted esomeprazole PK was in good agreement with external clinical data, suggesting the robustness and applicability of the current model for predicting esomeprazole PK.

Abstract
Purpose: Research comparing the clinical efficacy of dexlansoprazole and esomeprazole has been limited. This study aims to compare the clinical efficacy of single doses of dexlansoprazole (modified-release 60 mg) and esomeprazole (40 mg) after 24-week follow-up in patients with mild erosive esophagitis. Methods: We enrolled 86 adult GERD subjects, randomized in a 1:1 ratio to two sequence groups defining the order in which they received single doses of dexlansoprazole (n=43) and esomeprazole (n=43) for 8 weeks as initial treatment. Patients displaying complete symptom resolution (CSR) by the end of initial treatment (8 weeks) were switched to on-demand therapy until the end of 24 weeks. Follow-up endoscopy was performed either at the end of 24 weeks or when severe reflux symptoms occurred. Five patients were lost to follow-up, leaving 81 patients (dexlansoprazole, n=41; esomeprazole, n=40) in the per-protocol analysis. Results: The GERDQ scores at 4-, 8-, 12-, 16-, 20-, and 24-week posttreatment were less than the baseline score. The CSR, rate of symptom relapse, days to symptom resolution, sustained healing rate of erosive esophagitis, treatment failure rate, and the number of tablets taken in 24 weeks were similar in both groups. The esomeprazole group had more days with reflux symptoms than the dexlansoprazole group (37.3±37.8 vs 53.9±54.2; P=0.008). In the dexlansoprazole group, patients exhibited persistent improvement in the GERDQ score during the on-demand period (week 8 vs week 24; P<0.001) but not in the esomeprazole group (week 8 vs week 24; P=0.846). Conclusions: This study suggests that the symptom relief effect for GERD after 24 weeks was similar for dexlansoprazole and esomeprazole. Dexlansoprazole exhibited fewer days with reflux symptoms in the 24-week study period, with better persistent improvement in the GERDQ score in the on-demand period.

J Pharmacol Sci 2019; 139:361-366. [PMID: 30902567 DOI: 10.1016/j.jphs.2019.03.001] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2019] [Revised: 02/14/2019] [Accepted: 03/04/2019] [Indexed: 11/26/2022] Open
Abstract
Polymorphisms of cytochrome P450 (CYP) enzymes can affect enzymatic activity, drug metabolism and drug interactions. Although the potential for drug interactions is especially important when co-administering drugs with strong inductive or inhibitory potential towards drug-metabolizing enzymes, the relationship between CYP genotypes and the extent of the inductive or inhibitory effects remain poorly understood. We investigated the effects of rifampicin (inductive) and fluvoxamine (inhibitory) on metabolism of omeprazole and CYP2C19 enzymatic activity in 19 healthy Japanese subjects. Pharmacokinetic analyses of the CYP2C19 probe drug, omeprazole, were performed before and after rifampicin or fluvoxamine administration. The allele frequencies of the CYP2C19*1, CYP2C19*2 and CYP2C19*3 genotypes were 65.8%, 26.3% and 7.9%, respectively. Subjects with the CYP2C19*1 allele displayed higher levels of omeprazole metabolism than those without the CYP2C19*1 allele. Rifampicin increased omeprazole metabolism in all subjects irrespective of genotype, which suggested that CYP2C19 enzymatic activity was induced by rifampicin administration for all genotypes. Conversely, while fluvoxamine reduced omeprazole metabolism in subjects carrying the CYP2C19*1 allele, it had no impact on omeprazole pharmacokinetics in subjects without this allele. The genotyping of CYP2C19 may be useful for predicting drug interactions with metabolic inhibitors.

Effects of Plasma Albumin on the Pharmacokinetics of Esomeprazole in ICU Patients. BIOMED RESEARCH INTERNATIONAL 2019; 2018:6374374. [PMID: 30643812 PMCID: PMC6311297 DOI: 10.1155/2018/6374374] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/04/2018] [Revised: 10/28/2018] [Accepted: 11/26/2018] [Indexed: 11/18/2022]
Abstract
Objectives To evaluate the effects of plasma albumin on pharmacokinetics of esomeprazole in ICU patients. Methods This study was performed in 32 consecutive intensive care unit (ICU) patients. They were divided into two groups according to the plasma albumin levels. Nineteen patients with low plasma albumin levels (<30 g/L; male/female, 12/7) were assigned to low plasma albumin group (LPAG). Thirteen patients with plasma albumin levels >30 g/L (male/female, 9/4) were assigned to high plasma albumin group (HPAG). All patients were received intravenous (IV) of 40 mg esomeprazole in 5 min. Blood samples were collected via basilic vein at different time points and concentrations of esomeprazole were determined by UPLC-MS/MS. Results MRT(0-∞), t1/2, V, CL, and Cmax between two groups were significantly difference (P<0.05). Compared with HPAG, MRT(0-∞), t1/2, and V of esomeprazole in LPAG were increased by 1.42-fold, 1.49-fold, and 1.24-fold, respectively; the maximum drug concentration of esomeprazole in LPAG was decreased to 82.5%. AUC(0-∞) of LPAG was 1.23 times than that of group B. CL in LPAG was 80% of HPAG. There was no statistical difference between the two groups of AUC(0-∞) and CL. Conclusions Some pharmacokinetic parameters of esomeprazole may be changed in ICU patients with low plasma albumin.

Abstract
BACKGROUND AND AIM Proton pump inhibitors are effective for the treatment of gastric ulcers after endoscopic submucosal dissection (ESD). However, the most excellent therapy is controversial. Vonoprazan, an active potassium-competitive acid blocker, has a strong gastric acid secretion inhibitory effect, but its efficacy for the treatment of post-ESD gastric ulcers is unclear. Herein, we aimed to determine the healing effect of vonoprazan on post-ESD gastric ulcers. METHODS We carried out a prospective randomized controlled trial examining 92 patients who had undergone ESD for the treatment of gastric neoplasms between April 2015 and June 2016 at Machida Municipal Hospital. Patients were treated with 20 mg/day vonoprazan (V group) or 20 mg/day esomeprazole (E group) for 8 weeks. We evaluated the 8-week cure rate for artificial ulcers and any complications after ESD. RESULTS A total of 80 patients (median age, 73.5 years; 71.3% male) were analyzed. Cure rate for the V group was significantly higher than that for the E group (94.9% [37/39] vs 78.0% [32/41], respectively; P = 0.049). In a multivariate analysis, only vonoprazan was correlated with ulcer healing (odds ratio = 6.33; 95% CI = 1.21-33.20; P = 0.029). Delayed bleeding was experienced only in the E group (7.3% [3/41]), but no significant difference compared with the V group was observed (P = 0.241). CONCLUSION Vonoprazan was significantly superior to esomeprazole for the healing of post-ESD gastric ulcers and should be considered as a treatment of first choice.

Abstract
Objective CYP2C19 metabolic activity influences the efficacy of Helicobacter pylori eradication therapies comprising PPIs. Rabeprazole (RPZ) and esomeprazole (EPZ) are PPIs not extensively metabolized by CYP2C19. The aim of this study was to elucidate whether or not first-line triple therapies using RPZ or EPZ are equally effective in Japanese patients with different CYP2C19 genotypes. Methods Two-hundred patients infected with H. pylori were randomized to receive one of the following regimens: amoxicillin (750 mg), clarithromycin (200 mg), and either esomeprazole (20 mg) (EAC group) or rabeprazole (10 mg) (RAC group), twice a day for one week. The CYP2C19 polymorphisms were determined by polymerase chain reaction and the serum level of pepsinogens was measured. Results The eradication rates of the EAC and RAC regimens were 79.8% (95% confidential interval: 71.7-89.0%) and 74.7% (66.0-83.4%), respectively, in a per protocol (PP) analysis (p=0.488). The eradication rates of the EAC and RAC regimens were not significantly different between patients with the homo EM genotype (p=0.999) or hetero IM or PM genotypes (p=0.286). A lower PG I/II ratio was associated with lower eradication rates (p=0.025). Conclusion Although the eradication rate was less than 80%, the EAC and RAC regimens were equally effective in each CYP2C19 genotype group. The PG I/II ratio was associated with the results of EAC and RAC therapy in this series of patients.

Abstract
OBJECTIVES We evaluate the efficacy of concomitant therapy for Helicobacter pylori infection and the associated factors that influence it in China, where it has not previously been investigated. METHODS In this prospective study, 374 consecutive patients with H. pylori infection were randomly assigned to 10 day regimens of concomitant therapy with different proton pump inhibitors: esomeprazole (20 mg)/omeprazole (20 mg), amoxicillin (1000 mg), clarithromycin (500 mg) and metronidazole (400 mg). All drugs were administered twice daily. A [(13)C]urea breath test was performed at least 4 weeks after the completion of treatment. Gene polymorphisms and antimicrobial susceptibility were determined. RESULTS A total of 374 patients with active, uncomplicated duodenal ulcer disease were enrolled in the study (187 cases in each group). The overall eradication rate resulting from concomitant therapy was 90.7% (PP) and 86.1% (ITT) and the eradication rate was significantly higher in the group that received an esomeprazole-based regimen compared with the group that received an omeprazole-based regimen [95.4% versus 86.0%, respectively, P = 0.003 (PP) and 89.8% versus 82.4%, P = 0.036 (ITT), respectively]. Moreover, the omeprazole-based regimen was an independent risk factor for treatment failure (P = 0.039), as were CYP2C19 extensive metabolizer (P = 0.005), clarithromycin (P = 0.000) and metronidazole resistance (P = 0.000). In addition, CYP2C19 polymorphisms and antibiotic resistance had a synergistic effect on eradication rates. The majority of side effects were mild and none was serious. CONCLUSIONS The 10 day concomitant therapy yielded an eradication rate of nearly 90%. Antibiotic resistance, CYP2C19 polymorphisms and their interactions were closely associated with regimen efficacy.

Abstract
Proton pump inhibitors (PPIs) are potent acid-suppressive medications commonly used for management of acid-related diseases. Over the past decade, gastrointestinal injury following chemotherapy has attracted wide attention from oncologists. Two international clinical practice guidelines, the National Comprehensive Cancer Network (NCCN) and the Multinational Association of Supportive Care in Cancer (MASCC) antiemesis guidelines, recommend omeprazole for the treatment of chemotherapy-induced epigastric pain. In recent years, PPIs have been widely used for the prevention and treatment of chemotherapy-induced gastrointestinal mucositis. This paper summarizes the mechanisms by which chemotherapy causes damage to the gastrointestinal tract, the mechanisms underlying the protection afforded by PPIs against gastrointestinal injury induced by chemotherapy, and their clinical applications.

Abstract
The prevalence of Helicobacter pylori infection is gradually decreasing in Japan. On the main island of Japan, nearly all H. pylori isolates possess cagA and vacA with strong virulence. However, less virulent H. pylori strains are frequently found in Okinawa where cases of gastric cancer are the lowest in Japan. Eradication therapy for peptic ulcer, idiopathic thrombocytopenic purpura, gastric mucosa-associated lymphoid tissue lymphoma and early gastric cancer after endoscopic resection has been approved by the Japanese national health insurance system. However, the Japanese Society for Helicobacter Research recently stated that all 'H. pylori infection' was considered as the indication for eradication irrespective of the background diseases. To eliminate H. pylori in Japan, the Japanese health insurance system should approve the eradication of all H. pylori infections.
