Condition(s) targeted: Itching
Intervention: Ondansetron (Zofran) (Drug); Diphenhydramine (Benadryl) (Drug)
Sponsored by: United States Army Institute of Surgical Research
Official(s) and/or principal investigator(s):
Stuart Gross, MD, Principal Investigator, Affiliation: Wilford Hall Medical Center, Lackland AFB, San Antonio, TX
Steven E Wolf, MD, Study Director, Affiliation: US Army Institute of Surgical Research, Fort Sam Houston, TX
The purpose of this study is to see if a drug called ondansetron (Zofran) controls itching
from healing burn wounds as well or better than the usual drug used, diphenhydramine
Official title: A Pilot Study to Determine the Pruritic Benefits of Ondansetron Versus Diphenhydramine in Burn Patients Undergoing Wound Healing
Study design: Treatment, Randomized, Double Blind (Subject, Caregiver, Investigator), Active Control, Crossover Assignment, Bio-equivalence Study
Primary outcome: Ondansetron will have a greater ability to control pruritus in burn patients who are undergoing wound healing when compared to the standard of care, diphenhydramine.
A clear mechanism or cause for pruritus in patients recovering from burn has not been
While the exact mechanisms/pathways for itching are currently unclear, histamine antagonism
appears to be the most popular treatment. Whether histamine antagonism works predominantly
via peripheral inhibition or central sedation is uncertain. By treating another intermediary
in the pruritus cascade, it may be possible that an alternate treatment could be used while
eliminating some of the unwanted side effects of antihistamine at the same time.
