Tibenelast is an orally active phosphodiesterase inhibitor that was undergoing phase II clinical trials in the USA as a bronchodilator. In preclinical studies Tibenelast is moderately active against the lung and stomach enzyme while being a very weak inhibitor of the heart enzyme and it does not inhibit enzymes involved in arachidonic acid metabolism. Tibenelast shows potent anti-anaphylactic activity in guinea pigs without cardiovascular effects at the bronchodilatory doses.
