摘要:
An agent for the prophylaxis or treatment of TXA.sub.2 -mediated diseases, particularly, a TXA.sub.2 synthetase inhibitor, which comprises a pyridazinone compound of the formula (I) ##STR1## wherein each symbol is as defined in the specification, or a pharmacologically acceptable salt thereof as an active ingredient. The pyridazinone compound (I) and pharmacologically acceptable salts thereof used in the present invention have prophylactic and therapeutic activities against TXA.sub.2 -mediated diseases, particularly a TXA.sub.2 synthetase inhibitory action and are useful as an agent for the prophylaxis or treatment of TXA.sub.2 -mediated diseases, particularly as TXA.sub.2 synthetase inhibitors.
摘要:
A novel carboxylic acid compound having a condensed ring, which is represented by the formula (I) ##STR1## wherein each symbol is as defined in the specification, a pharmacologically acceptable salt thereof, a pharmaceutical composition thereof and pharmaceutical use thereof. The novel carboxylic acid compound having a condensed ring and pharmacologically acceptable salt thereof of the present invention have superior GPIIb/IIIa antagonism in mammals inclusive of human; can be administered orally; have long life in blood and low toxicity; and show less side-effects. Accordingly, they are extremely useful for the prophylaxis and treatment of thrombotic diseases and other diseases.
