Abstract
Background: To determine the results of standardized ulcer treatment regimes and effects of the oral thromboxane A 2 antagonist Ifetroban (250 mg daily) on healing of chronic lower-extremity venous stasis ulcers. Methods: In a prospective, randomized, double blind, placebo-controlled multicenter study, 165 patients were randomized to Ifetroban (n = 83) versus placebo (n = 82) for a period of 12 weeks. Both groups were treated with sustained graduated compression and hydrocolloid. Ulcer size was measured weekly by tracings and computerized planimetry. A total of 150 patients completed the study. Results: Complete ulcer healing was achieved after 12 weeks in 55% of patients receiving Ifetroban and in 54% of those taking a placebo with no significant differences; 84% of ulcers in both groups achieved greater than 50% area reduction in size. Conclusions: These results are likely to be useful as a benchmark for comparison with other treatment protocols concerning the care of chronic lower-extremity stasis ulcers.
