Omeprazole, 20 mg once daily, provides effective prophylactic therapy in patients at risk of developing NSAID-associated peptic ulcers or dyspeptic symptoms.

The study discloses a strong and dose-dependent association between body mass and reflux oesophagitis in women as opposed to no association among men. This association might be caused by increased oestrogen activity in overweight and obese females.

To evaluate the therapeutic potential of the newly developed proton pump inhibitor lansoprazole in patients with reflux oesophagitis, we performed a double-blind randomized clinical trial comparing 20 mg omeprazole and 30 mg lansoprazole, involving 229 patients at 9 Scandinavian hospitals. The treatment period was 4 or 8 weeks, and main efficacy variables were healing of endoscopic changes, relief of reflux symptoms, and occurrence of adverse events. No significant difference in terms of healing was found, either after 4 or after 8 weeks' treatment. Patients receiving lansoprazole experienced a greater improvement in heartburn after 4 weeks (p = 0.03), and there was a similar trend for acid regurgitation. Lansoprazole was found to be an effective and safe alternative to omeprazole in short-term treatment of moderate reflux oesophagitis.

SUMMARYBackground: On-demand therapy with esomeprazole is effective for long-term treatment of non-erosive gastrooesophageal reflux disease, but it has not been evaluated in erosive gastro-oesophageal reflux disease. Aims: To compare endoscopic and symptomatic remission over a 6-month period when patients with healed erosive gastro-oesophageal reflux disease are treated with esomeprazole 20 mg, either once daily or on-demand. Methods: Patients with verified erosive reflux oesophagitis of Los Angeles grades A-D were enrolled. Following 4-8 weeks treatment with esomeprazole 40 mg daily, those who were endoscopically healed and had symptom control during the last week were randomized to maintenance therapy for 6 months with esomeprazole 20 mg, taken either once daily or on-demand.
