6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

Gastroesophageal Reflux Disease (GERD) Adults Safety in nine randomized comparative US clinical trials in patients with GERD included 1,473 patients on oral pantoprazole (20 mg or 40 mg), 299 patients on an H 2 -receptor antagonist, 46 patients on another PPI, and 82 patients on placebo.

The most frequently occurring adverse reactions are listed in Table

The number of patients treated in comparative studies with pantoprazole sodium for injection is limited;

however, the adverse reactions seen were similar to those seen in the oral studies.

Thrombophlebitis was the only new adverse reaction identified with pantoprazole sodium for injection.
