title: Results of reflex photometric determinations of vasoconstriction after topical steroid application. Tachyphylaxis, relative and absolute refractory phase after single and multiple application of steroid.
abstract: After a repeated intensive topical application (4-h rhythm), there it is phase already after 28 h in which the cutaneous vessels are insensitive (refractory) to constrictor stimuli due to steroids. This refractory phase lasts for at least 68 h. A single local application of steroid likewise leads to a diminished vasoreactivity for a limited time. The relative refractory phase is limited to 96 h under the given experimental conditions.
