PREVPAC consists of a daily administration pack containing two PREVACID 30-mg capsules, four amoxicillin 500-mg capsules, USP, and two clarithromycin 500-mg tablets, USP, for oral administration.
The components in PREVPAC (PREVACID, amoxicillin, and clarithromycin) are indicated for the treatment of patients with
infection and duodenal ulcer disease (active or one-year history of a duodenal ulcer) to eradicate
H. pylori. Eradication of
has been shown to reduce the risk of duodenal ulcer recurrence (See CLINICAL STUDIES and DOSAGE AND ADMINISTRATION).
To reduce the development of drug-resistant bacteria and maintain the effectiveness of PREVPAC and other antibacterial drugs, PREVPAC should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
Published Studies Related to Prevpac (Clarithromycin / Amoxicillin / Lansoprazole)
Recent success of pantoprazole -or lansoprazole- based clarithromycin plus amoxicillin treatment in the eradication of Helicobacter pylori. [2004.12]
BACKGROUND/AIMS: There are some reports showing that resistance of Helicobacter pylori (H. pylori) to clarithromycin has increased in recent years. We aimed to investigate the current success of a most popular first-line eradication regimen by using two different proton pump inhibitors: lansoprazole and pantoprazole... CONCLUSIONS: The most popular first-line eradication protocols of H. pylori achieved only a moderate success in the current study. Alternative therapy options are needed instead of clarithromycin-based triple treatment for eradication of H. pylori. The choice of proton pump inhibitor is not important in the eradication rate of H. pylori.
Comparison of the efficacy of 250 mg and 500 mg clarithromycin used with lansoprazole and amoxicillin in eradication regimens for Helicobacter pylori infection. [2004.07.31]
CONCLUSIONS: The cure rates for the two regimens were similar, although adverse effects were more frequent with the LAC500 regimen, suggesting that 250 mg of clarithromycin b.d. may be sufficient in our patient population.
Absence of symptomatic benefit of lansoprazole, clarithromycin, and amoxicillin triple therapy in eradication of Helicobacter pylori positive, functional (nonulcer) dyspepsia. [2003.09]
OBJECTIVES: The aim of this study was to compare the effect of a combination of lansoprazole, clarithromycin, and amoxicillin (LCA) versus placebo on the severity of symptoms in functional dyspepsia patients who were positive for Helicobacter pylori (H. pylori)... CONCLUSIONS: There was no difference in sustained improvement of dyspepsia symptoms when LCA was compared with placebo. An 82% cure rate of H. pylori infection was observed with LAC.
Lafutidine, a novel histamine H2-receptor antagonist, vs lansoprazole in combination with amoxicillin and clarithromycin for eradication of Helicobacter pylori. [2003.04]
BACKGROUND: In contrast to the growing amount of data concerning proton pump inhibitor-based triple therapy for Helicobacter pylori infection, it is still controversial whether proton pump inhibitor can be replaced by H2 receptor antagonist without compromising efficacy. Lafutidine is a novel potent H2 receptor antagonist with gastroprotective activities such as enhancement of gastric mucosal blood flow... CONCLUSIONS: The lafutidine-clarithromycin-amoxicillin therapy yielded satisfactory results for eradicating H. pylori, which was comparable with those of the lansoprazole-based regimen with the same drug combination.
Impact of clarithromycin resistance and CYP2C19 genetic polymorphism on treatment efficacy of Helicobacter pylori infection with lansoprazole- or rabeprazole-based triple therapy in Japan. [2003.01]
OBJECTIVE: Helicobacter pylori treatment failure is thought to be due mainly to polymorphic cytochrome P450 2C19 (CPY2C19) genetic polymorphism, associated with proton pump inhibitor metabolism, and antimicrobial susceptibility. This report has ascertained which was more important, CPY2C19 polymorphism or antimicrobial susceptibility, when using 1-week lansoprazole-based or rabeprazole-based triple therapy in Japan... CONCLUSIONS: The key to successful eradication of H. pylori, using lansoprazole or rabeprazole with clarithromycin and amoxicillin, is clarithromycin susceptibility, not CPY2C19 polymorphism.
