Pruritus Clinical Trial
Official title:
Evaluation of Provase in the Post Burn Rehabilitation Population for Itch Control and Moisturization Properties
Severe itching following burn injury is a common complication. As many as 87% of burn
patients report severe itching. The intense itching can increase anxiety and can interfere
with sleep and normal activities of daily living thus affecting quality of life. Often the
itching will become so intense patients will scratch or rub the skin until an open wound
develops. Current treatment for itching includes antihistamines, steroids. and/or
moisturizers, but too often, the patient does not receive relief, even from drugs, and
suffers undesirable side effects.
Swiss-American Products, Inc, has developed a new skin moisturizer containing a blend of
endopeptidase enzymes. These products have resolved itching in other types of skin disease
such as dermatitis. The hypothesis that itching can be reduced through the use of these
endopeptidase enzyme containing products in the post burn population will be tested.
