Study discontinuation because of loss of treatment
efficacy or relapse of EO from the trials of most placebotreated
patients made meaningful safety comparisons difficult
within each trial. In addition, pooling of adverse
event rates tends to include RCTs of the same molecule
regardless of study populations. Therefore, no indirect comparisons were attempted on the safety endpoints in
this review, which is limited to the only 11 eligible RCTs
for indirect treatment effectiveness comparisons on different
study populations. However, in general, both dexlansoprazole
and esomeprazole were well tolerated in the
reviewed RCTs with majority of the reported adverse
events being mild or moderate, similar to that of lansoprazole
and omeprazole, respectively, which have a longestablished
history of use in patients with GERD and
other acid-related disorders
