Final answer:
The first line triple therapy for H Pylori infection consists of omeprazole, amoxicillin, and clarithromycin (OAC) and is recommended by the US FDA.
Step-by-step explanation:
The first line triple therapy for H Pylori infection is a combination of three drugs: omeprazole, amoxicillin, and clarithromycin (OAC). This treatment is recommended by the US Food and Drug Administration and is typically administered for a duration of 10 days. Omeprazole is not an antibiotic, but it is used to decrease acid levels because H. pylori prefers acidic environments.
