Use agents known to be effective against H pylori.

Metronidazole (Flagyl)

Reduced to its active form intracellularly only by anaerobic organisms, then disrupts the helical structure of DNA and inhibits bacterial nucleic acid synthesis.

Tetracycline (Sumycin)

Inhibits bacterial protein synthesis by binding with 30S and possibly 50S ribosomal subunit(s).

Clarithromycin (Biaxin)

Inhibits bacterial growth, possibly by blocking the dissociation of peptidyl tRNA from ribosomes, causing the arrest of RNA-dependent protein synthesis.

Amoxicillin (Amoxil, Trimox)

Inhibits the final stage of bacterial cell wall synthesis by binding to specific PBPs on the inner part of the bacterial wall, leading to bacterial lysis.
