*FOR NEXIUM IV ONLY. Administration site reactions have mainly been observed in a study with high-dose exposure over 3 days (72 hours). In the non-clinical program for esomeprazole intravenous formulation there was no evidence of vaso-irritation but a slight tissue inflammatory reaction at the injection site after subcutaneous (paravenous) injection was noted. The non-clinical findings somewhat indicated that the clinical tissue irritation was concentration related.
