Final answer:
Prevacid (lansoprazole) in h. pylori is therapy helps decrease stomach acid levels and inhibits the growth of the bacteria.
Step-by-step explanation:
Lansoprazole is a medication that is used to decrease acid levels in the stomach. It is part of a triple therapy regimen for treating Helicobacter pylori (H. pylori) infection, which is a major cause of peptic ulcers. The current protocol for treating H. pylori involves a combination of lansoprazole, amoxicillin, and clarithromycin taken for either 10 or 14 days.
H. pylori prefers acidic environments, so by reducing acid levels with lansoprazole, the bacteria's growth can be inhibited. This, combined with the antibiotics, helps to cure the infection and prevent further complications such as ulcers and stomach cancer.
Therefore lansoprazole is used as part of a triple therapy regimen for treating H. pylori infection. It helps decrease stomach acid levels and inhibits the growth of the bacteria. The combination of lansoprazole, amoxicillin, and clarithromycin is taken for 10 or 14 days to cure the infection and prevent complications.
