Outcome Measures

Primary Outcomes (3)

    1- Day 2

  • change in serum creatinine level

    Mean change in serum creatinine (mg/dL) from baseline to end of treatment.

    Day 2

  • Incidence of adverse drug reactions

    Number of participants who develop adverse drug reactions including nausea, vomiting, or anaphylactoid reactions during treatment

    Day 2

Secondary Outcomes (2)

  • rate of clinical recovery

    immediately after the intervention

  • incidence of serious complications

    immediately after the intervention
