Rosacea
Conditions
Brief summary
Rosacea is a common skin condition associated with easy blushing and red face; many patients with rosacea react to sunlight with increased redness. The purpose of this study is to determine if the use of a topical medication will help reduce sunlight induced redness and irritation in patients with rosacea.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Difference in redness of Ultraviolet B induced erythema with 4% imipramine | 10 minutes post-treatment | Erythema change from baseline with 4% imipramine application in response to a low level of UVB are measured by using a mexameter device and thermal photography. |
| Difference in redness of Ultraviolet B induced erythema with 4% amitriptyline | 10 minutes post-treatment | Erythema change from baseline with 4% amitriptyline application in response to a low level of UVB are measured by using a mexameter device and thermal photography. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Tolerability of 4% imipramine on facial skin | 10 minutes post-treatment | The tolerability of 4% imipramine on facial skin at baseline/Day 1 compared to Day 2 is measured by the Visual Analog Scale for pain and itch. \[0= no skin pain/itch; 10 = severe skin pain/itch\] |
| Tolerability of 4% amitriptyline on facial skin | 10 minutes post-treatment | The tolerability of 4% amitriptyline on facial skin at baseline/Day 1 compared to Day 2 is measured by the Visual Analog Scale for pain and itch. \[0= no skin pain/itch; 10 = severe skin pain/itch\] |
