Pilot Studies Testing the Use of Oral Amitriptyline in Reducing Localized Burn Injury-induced Microvesicle Particle Release
Wright State University
Summary
The purpose of this study is to determine the amount of substances contained in skin known as microvesicle particles (MVP). The hypothesis to be tested in this study is that treatment with a single dose of 75mg of amitriptyline will block the MVP released from the skin from a very small localized burn injury.
Description
The purpose of this study is to determine the amount of substances contained in skin known as microvesicle particles (MVP). Studies suggest these MVP are involved in many conditions such as after the thermal burn injury. In fact, there is evidence suggesting that these MVP cause severe toxic effects and could be responsible for deaths following extensive thermal burn injuries. These particles are typically found in skin and are evaluated by taking a portion of area with skin biopsy. Of importance, MVP release from the skin can be blocked by drugs such as amitriptyline, a medicine which is a tr…
