Rabeprazole tablet strengths and course lengths for the GPhC assessment

The manufacturer's UK product information for Pariet gastro-resistant tablets states that the recommended dose for active duodenal ulcer and active benign gastric ulcer is 20 mg once daily in the morning, that most patients with duodenal ulcer heal within four weeks, and that most patients with benign gastric ulcer heal within six weeks.

The same information states that for erosive or ulcerative gastro-oesophageal reflux disease the recommended dose is 20 mg once daily for four to eight weeks, and that for long term management a maintenance dose of 20 mg or 10 mg once daily can be used depending on response.

It also states that for eradication of Helicobacter pylori, Pariet 20 mg twice daily is given with clarithromycin 500 mg twice daily and amoxicillin 1 g twice daily for 7 days.

Each question fixes the values needed for its arithmetic. Write the unit beside every step and distinguish a single dose from a daily total or a supply period. All prescriptions and patients here are fictional; these are revision materials, not for patient care.
