Health-related quality of life outcomes of omeprazole versus ranitidine in poorly responsive symptomatic gastroesophageal reflux disease.

OBJECTIVE: This study evaluated changes in health-related quality of life (HRQL) outcomes of once-daily omeprazole compared with ranitidine for the short-term treatment of patients with poorly responsive symptomatic gastroesophageal reflux disease (GERD). METHODS: A double-blind, randomized clinical trial, compared omeprazole versus ranitidine for the treatment of poorly responsive GERD. Eligible patients had a history of predominant heartburn symptoms with symptomatic heartburn after 6 weeks of ranitidine treatment. Patients were randomized to omeprazole 20 mg once daily (n = 156) or ranitidine 150 mg twice daily (n = 161) and followed for 8 weeks. Assessments were completed at baseline and after 8 weeks with physician-rated symptoms: Gastrointestinal Symptom Rating Scale (GSRS); Psychological General Well-Being (PGWB) Index; Sleep Scale; Impact on Daily Activities Scale, and Overall Treatment Effect. Primary HRQL endpoints were the GSRS reflux scale and PGWB total score. RESULTS: No differences between the 2 treatment groups were observed in baseline demographic, clinical or HRQL measures. After 8 weeks, omeprazole-treated patients had greater improvement in GSRS reflux scale scores (p<0.0001) and PGWB total scores (p = 0. 019) compared with ranitidine-treated patients. Significant between group differences favoring omeprazole were also observed in GSRS total scores (p<0.0001), abdominal pain scale scores (p = 0.003), and indigestion scale scores (p = 0.003), Impact on Daily Activities (p = 0.001), PGWB positive well-being (p = 0.015), anxiety (p = 0. 030), and general health scale scores (p = 0.010). Patient ratings of overall treatment effect demonstrated the significantly (p<0. 0001) greater benefits of omeprazole (mean = 5.26) compared with ranitidine treatment (mean = 3.83). CONCLUSIONS: Omeprazole treatment significantly reduced persistent reflux-related symptoms and normalized psychological well-being compared with ranitidine in poorly responsive symptomatic patients with GERD.[1]
