Abstract

BACKGROUND:

Frequent nighttime heartburn is common. Lansoprazole 15 mg is indicated for treatment of heartburn and other gastro-oesophageal reflux disease-related symptoms.

AIM:

To evaluate the efficacy and safety of lansoprazole in self-treating subjects with frequent nocturnal heartburn.

METHODS:

A total of 864 subjects with heartburn on >or=2 days/week over the past month were randomized to double-blind treatment with lansoprazole 15 or 30 mg or placebo each morning. Endpoints were percentage of night times without heartburn (primary), percentage of 24-h days without heartburn and percentage of subjects without heartburn on day 1.

RESULTS:

Mean percentage of night times without heartburn was significantly greater with lansoprazole 15 mg (61.3%) or lansoprazole 30 mg (61.7%) vs. placebo (47.8%) over 14 days (P < 0.0001 vs. placebo for both doses). Percentage of 24-h days without heartburn and percentage of subjects without heartburn on day 1 were significantly greater with lansoprazole 15 or 30 mg vs. placebo.

CONCLUSIONS:

Both lansoprazole 15 and 30 mg were highly effective and well tolerated in reducing symptoms in subjects with frequent nighttime heartburn. The benefit of therapy on 24-h heartburn and nighttime heartburn on day 1 of treatment was also evident. Lansoprazole 15 mg is a suitable choice for management of frequent nighttime heartburn.
