First-week clinical responses to dexlansoprazole 60 mg and esomeprazole 40 mg for the treatment of grades A and B gastroesophageal reflux disease

Core Tip

Core tip: No existing report has investigated the short-term clinical effects of dexlansoprazole 60 mg vs esomeprazole 40 mg. This study compared the one-week clinical effects of a single dose of the two drugs for grades A and B erosive esophagitis. We enrolled 175 adult patients with gastroesophageal reflux disease (GERD) and randomized them in a 1:1 ratio into a dexlansoprazole (n = 88) or esomeprazole group (n = 87) for an intention-to-treat analysis (ITT). The primary end-points were the complete symptom resolution (CSR) rates at days 1, 3, and 7. The CSRs for both groups were similar at days 1, 3 and 7. In the subgroup analysis, female patients achieved higher CSRs in the dexlansoprazole group than in the esomeprazole group at day 3 (38.3% vs 18.4%, P = 0.046). In the esomeprazole group, female sex was a negative predictive factor for CSR at post-dose day 1 [OR = -1.249 ± 0.543; 95%CI: 0.287 (0.099-0.832), P = 0.022] and day 3 [OR = -1.254 ± 0.519; 95%CI: 0.285 (0.103-0.789), P = 0.016]. This pilot study suggested that the overall CSR rates for GERD patients were similar at days 1 through 7 for both the dexlansoprazole and esomeprazole groups, although a higher CSR was observed at day 3 in female patients who received a single dose of dexlansoprazole.
