In this pilot, randomized controlled trial,
79 subjects were allocated to A. vera syrup (standardized
to 5.0 mg polysaccharide per mL of syrup)
at a dose of 10 mL/d, omeprazole capsule (20 g/d)
or ranitidine tablet (150 mg in a fasted state in the
morning and 150 mg 30 min before sleep at night)
for a period of 4 weeks. The frequencies of eight main symptoms of GERD (heartburn, food regurgitation,
flatulence, belching, dysphagia, nausea,
vomiting and acid regurgitation) were assessed at
weeks 2 and 4 of the trial.
