Omeprazole, a proton pump inhibitor (PPI) is one of the most widely prescribed drugs used world wide and is available over-the-counter in some countries. According to the results of numerous clinical studies, CYP2C19 polymorphisms is an important factor affecting the pharmacokinetics of most PPIs.According to some research,Asian populations is characterized by high prevalence of defect CYP2C19a...
BACKGROUND The effects of PPI are variable owing to the CYP2C19 polymorphisms. However, whether the polymorphisms could affect the Hp eradication efficacy of triple therapy is still not clear. The present study aimed to assess the effects of CYP2C19 gene polymorphisms on proton pump inhibitor (PPI), amoxicillin, and levofloxacin triple therapy for Helicobacter pylori (Hp) eradication. MATERIAL ...
Individuals vary widely in their response to drug treatment. After receiving doses of a drug that are recommended based on a population average, some patients could have an insufficient response, whereas others may experience adverse effects. Of the many factors causing variability in drug response across individuals, genetic polymorphism of drug-metabolizing enzymes is deemed to be one of the ...
This is the first study performed in population from Bosnia & Herzegovina (BH), in which we analysed a significance of genetic variations in drug-metabolising enzyme, cytochrome P450 (CYP), in pathogenesis of Type 2 diabetes. We have determined allele frequencies for CYP2C9*2, CYP2C19*2, and CYP2D6*4 in diabetic patients and nondiabetic controls. Genomic DNA was extracted from blood samples col...
Clopidogrel hydrogen sulfate (CHS) is a thienopyridine, which can be used to prevent cardiovascular complications alone or in combination with acetyl salicylic acid as an important antiplatelet agent. Clopidogrel benzene sulfonate (CB) is a special clopidogrel salt that can be used as a conventional drug for antiplatelet effects, but the mechanism is still unknown. This study aimed to compare t...
Background: Not all patients with acid-related disorders receiving proton pump inhibitor (PP) treatment get adequate gastric pH control. The genetic variation of receptors, metabolic enzymes, and transporters are known to cause failures of therapies. We have conducted a study to evaluate the influence of gastric H+/K+-ATPase, CYP2C19, and ABCB1 polymorphisms on the pharmacokinetic and pharmacod...
OBJECTIVES The aim of this study was to assess the degree of platelet inhibition by adjunctive cilostazol in patients with acute myocardial infarction (AMI) according to hepatic cytochrome P450 2C19 (CYP2C19) genotype. BACKGROUND Although adjunctive cilostazol intensifies platelet inhibition in AMI patients, it is not established whether this regimen can be free from the effect of CYP2C19 los...
The interindividual variability of Proton Pump Inhibitor (PPI) therapy results from the phenotype associated with cytochrome P450 2C19 (CYP2C19) gene, namely CYP2C19*17 allele. Our aim was to characterize patients’ genetic undergoing PPI therapy. A sample 33 oral mucosa cells Portuguese pharmacy patients collected, followed by genotyping. allelic frequencies CYP2C19*1 (-806C) and (-806T) were 7...
BACKGROUND Lansoprazole, amoxicillin, and clarithromycin are commonly used drugs for eradication of Helicobacter pylori (H. pylori). A few studies reported that the eradication rate was influenced by the functional polymorphism of CYP2C19, whose product metabolizes proton pomp inhibitors including lansoprazole. METHODS This study examined the eradication rate among 67 participants in the poly...
