PPI Dose Conversion

• In 2004, when the original guideline was developed (CG17), doses of proton pump inhibitors (PPIs) were based on the British National Formulary (BNF) at the time, as in table 1 below.
• During the update of this guideline (2014), the Guideline Development Group (GDG) has further defined the PPI doses specifically for severe oesophagitis and H pylori eradication therapy, as in tables 2 and 3 below.
