摘要: The commonly used regimens for the eradication of Helicobacter pylori infection consist administration proton pump inhibitors (PPIs) and 1 to 3 antimicrobial agents, such as amoxicillin, clarithromycin, metronidazole, fluoroquinolone, or tetracycline. Each agent has its own pharmacologic characteristics. PPIs are metabolized by cytochrome P450 2C19 (CYP2C19), which is polymorphic. CYP2C19 genotypic differences in pharmacokinetics pharmacodynamics influence rates H PPI-containing regimens. Amoxicillin a time-dependent antibiotic, whereas tetracycline, fluoroquinolone not. plasma half-life agents also differs among these antibiotics. To achieve consistently high rates, must be designed based on good understanding resistance patterns bacteria characteristics therapy.
