AIMS: Proton pump inhibitors (PPIs) belong to the most frequently used drugs, also in patients with cirrhosis. PPIs are extensively metabolized by the liver, but practice guidance on prescribing in cirrhosis is lacking. We aim to develop practical guidance on the safe use of PPIs in cirrhosis. METHODS: A systematic literature search identified studies about the safety (i.e. adverse events) and pharmacokinetics of PPIs in cirrhotic patients. This evidence and data from the product information was reviewed by an expert panel who classified drugs as safe; no additional risks known; additional risks known; unsafe; or unknown...

Background/Aims: Moxifloxacin-based sequential therapy showed an excellent eradication rate as the first line treatment of Helicobacter pylori ( H. pylori ) infection. However, to the best of our knowledge, there were only a few studies on the treatment of those with failed moxifloxacin-based sequential therapy. Hence, this study was to investigate the efficacy of bismuth-containing quadruple therapy in those with failed moxifloxacin-based sequential or reverse sequential therapy for H...

BACKGROUND AND GOAL: Cytochrome P450 (CYP) enzymes are responsible for the conversion of clopidogrel into its active metabolite and the metabolism of proton pump inhibitors (PPIs), which may also inhibit CYP enzymes. A current Food and Drug Administration advisory suggests avoiding esomeprazole and omeprazole while taking clopidogrel because of concerns that PPIs may compromise clopidogrel's antiplatelet effects. The objective of the present study was to examine the robustness of this interaction using a well-controlled study design in a population of participants free of confounders...

Background: Helicobacter pylori , the cause of most peptic ulcer diseases, infects approximately 50% of the population worldwide. Indian data on cost and effectiveness of the standard first-line therapies for H. pylori eradication are scarce. Thus, the present study was aimed at comparing the cost and efficacy of two standard first-line therapies: Regimen I comprising pantoprazole (40 mg) plus amoxicillin (750 mg) plus clarithromycin (500 mg) (PAC) and Regimen II comprising rabeprazole (20 mg) plus amoxicillin (625 mg) plus metronidazole (200 mg) (RAM)...

Sofosbuvir plus ledipasvir (SOF-LDV) combination therapy is a promising therapy for post-transplant hepatitis C virus (HCV) reinfection. It is known that gastric pH elevation induces lower absorption of ledipasvir; therefore, the use of proton pump inhibitors (PPIs) should be considered regarding dose reduction after SOF-LDV therapy induction. Here, we report two patients who developed duodenal ulcers due to the discontinuation of PPIs after the induction of SOF-LDV therapy for post-transplant HCV reinfection...

A new validated bio-analytical LC-MS/MS method was developed for the simultaneous extraction and determination of four proton pump inhibitors: esomeprazole, lansoprazole, pantoprazole and rabeprazole in human plasma using escitalopram as an internal standard. The proteins in plasma samples were precipitated using acetonitrile for the extraction of analytes which is a simple economic method. The separation was accomplished using a mobile phase composed of 10 mM ammonium formate: acetonitrile: methanol (20:40:40% v/v) at a flow rate of 0...

BACKGROUND/AIMS: Phase III study demonstrated that vonoprazan-based Helicobacter pylori eradication therapy achieved higher eradication rate compared with lansoprazole. However, there is no study that evaluated the efficacy of vonoprazan in a large sample in real world. We investigated the eradication rate and safety of vonoprazan-based eradication therapy compared with our randomized control trial using second-generation proton pump inhibitor (PPIs). METHODS: (First study) A total of 147 patients who have H...

Proton-pump inhibitors (PPIs), such as omeprazole, lansoprazole, and rabeprazole, are used for the treatment of gastroesophageal reflux disease and peptic ulcer disease. The use of PPIs has increased, especially in older individuals, and a pharmacoepidemiological study indicated that the use of PPIs peaks in people aged 80 years or older. In this population, Alzheimer's disease (AD) is a common neurological disorder and type of dementia, occurring with a frequency of approximately 10%. Currently, over 45 million people are estimated to have dementia worldwide, and it is a major cause of death in the elderly...

BACKGROUND: The standard triple Helicobacter pylori regimen now shows unacceptably low treatment success in Korea. Administration of the concomitant therapy for 10 days, which has a high cure rate, is recommended as an alternative first-line treatment in areas of high clarithromycin resistance including Korea. Recently, modified bismuth-containing quadruple therapy with amoxicillin (PAM-B therapy) showed excellent results, regardless of dual clarithromycin and metronidazole resistance...

BACKGROUND AND AIMS: Endoscopic submucosal dissection (ESD) is a well-established minimally invasive treatment for early gastric cancer. To heal ESD-induced ulcers, we commonly prescribe proton pump inhibitors (PPIs). Vonoprazan is our new choice, which is reported to have a stronger and longer acid inhibitory effect than existing PPIs. Here, we aimed to evaluate the efficacy of vonoprazan for healing ESD-induced ulcers compared with rabeprazole. METHODS: We reviewed 190 patients who underwent ESD before and after we switched the acid secretion inhibitor from rabeprazole to vonoprazan...

BACKGROUND: Since the introduction of the first proton pump inhibitor (PPI) 20 years ago, studies have examined the presence of a rebound effect when this treatment is discontinued. These studies are heterogeneous and contradictory: the last literature review on the rebound in gastric acidity dates from 2006 and did not allow to conclude on the subject. Our objective was to carry out an up-to-date literature review on the existence and characteristics of this gastric acid rebound at the end of PPIs...

The pharmacokinetics (PK) and pharmacodynamics (PD) of proton pump inhibitors differ among cytochrome P450 (CYP) 2C19 genotypes. Therefore, we developed azeloprazole sodium (Z-215), a novel proton pump inhibitor, whose metabolism is not affected by CYP2C19 activity in vitro. However, the PK and PD of azeloprazole sodium have not been evaluated in Japanese subjects. We conducted an open-label, crossover study in healthy Japanese male volunteers to evaluate the plasma concentration and intragastric pH with respect to CYP2C19 genotype after repeated administration of 10, 20, and 40 mg azeloprazole sodium and 10 and 20 mg rabeprazole sodium (rabeprazole)...

BACKGROUND: Rabeprazole at 10 or 20 mg twice daily (b.i.d.) has been reported to be highly effective in the treatment of proton pump inhibitor (PPI)-resistant reflux esophagitis (RE) that is refractory to the standard once-daily PPI regimen. We evaluated the efficacy and safety of rabeprazole maintenance therapy at 10 mg once daily (q.d.) or b.i.d. for longer than 8 weeks. METHODS: Patients with RE refractory to standard PPI regimens for at least 8 weeks were enrolled...

A novel Liquid Chromatography-tandem mass spectrometry (LC-MS/MS) method is presented for the quantitative determination of two potential genotoxic impurities (PGIs) in rabeprazole active pharmaceutical ingredient (API). In order to overcome the analytical challenges in the trace analysis of PGIs, a development procedure supported by Quality-by-Design (QbD) principles was evaluated. The efficient separation between rabeprazole and the two PGIs in the shortest analysis time was set as the defined analytical target profile (ATP) and to this purpose utilization of a switching valve allowed the flow to be sent to waste when rabeprazole was eluted...
