Effect of thromboxane A2 synthetase inhibitor, OKY-046, on sputum in chronic bronchitis and diffuse panbronchiolitis.
The mechanisms of excessive sputum production are only partially understood. We speculated that a selective thromboxane (Tx) A2 synthetase inhibitor, OKY-046, now used in the treatment of asthma in Japan, could decrease excess sputum production in patients with chronic airways disease. To test this hypothesis, we carried out a double-blind, placebo-controlled study of the effects of OKY-046, ad...
متن کاملBeneficial effect of OKY-046, a selective thromboxane A2 synthetase inhibitor, on experimental cerebral vasospasm.
Effects of OKY-046, a selective inhibitor of thromboxane (TX)A2 synthetase and a platelet aggregation inhibitor, on in vitro and in vivo models of cerebral vasospasm were studied. The contraction of the isolated rabbit basilar artery by an exposure to 1.0 ml of whole rabbit blood plus 0.05 or 0.1 units/ml of thrombin was diminished by the treatment with 10(-4) M of OKY-046 and/or 10(-6) M of ci...
متن کاملInhibitory effect of a selective thromboxane synthetase inhibitor, OKY-046, on acetaldehyde-induced bronchoconstriction in asthmatic patients.
We recently reported that inhaled acetaldehyde causes bronchoconstriction indirectly via histamine release in patients with asthma. The purpose of this study was to investigate a role of thromboxane A2 in acetaldehyde-induced bronchoconstriction in asthmatic airways. We investigated the bronchial response to inhalation of ascending doses (5, 10, 20, and 40 mg/ml) of acetaldehyde in nine asthmat...
متن کاملThe effect of a thromboxane synthetase inhibitor, OKY-046, on urinary excretion of immunoreactive thromboxane B2 and 6-keto-prostaglandin F1 alpha in patients with ischemic cerebrovascular disease.
Thromboxane synthetase activity is selectively inhibited by (E)-3-[4-(1-imidazolylmethyl)phenyl]-2-propenoic acid hydrochloride monohydrate (OKY-046). A single dose of 100 mg OKY-046 was orally administered to patients with ischemic cerebrovascular disease and healthy volunteers. Platelet aggregation and thromboxane B2 (TXB2) generation of intact and homogenised platelets induced by 1.0 mM sodi...
متن کاملEffect of OKY-1581, a thromboxane synthetase inhibitor, on coronary thrombosis in the conscious dog.
OKY-1581, a new thromboxane synthetase inhibitor, was studied in a conscious canine model of coronary thrombosis. After thoracotomy with placement of a left circumflex coronary artery flow probe and implantation of an electrode into the circumflex artery, animals were assigned randomly to the following groups: 0.9% NaCl vehicle control or OKY-1581 1 mg/kg every 4 intravenously for 24 h. During ...
