Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
43 words
A method of inhibiting thromboxane synthetase activity, and thus inhibiting arachidonic acid-induced platelet aggregation and broncho-constriction, which comprises administering to the circulatory system of a mammalian host in need thereof an effective amount of 1-(3-phenyl-2-propenyl)-1H-imidazole or a pharmaceutically acceptable acid addition salt thereof.
Claim 2
Independent Claim
43 words
A method of inhibiting thromboxane synthetase activity, and thus inhibiting arachidonic acid-induced platelet aggregation and broncho-constriction, which comprises administering to the circulatory system of a mammalian host in need thereof an effective amount of 1-(3-phenyl-2-propenyl)-1H-imidazole or a pharmaceutically acceptable acid addition salt thereof.
Claim 3
Dependent Claim
26 words
The method as defined in claim 1 wherein said 1-(3-phenyl-2-propenyl)-1H-imidazole is administered in an amount within the range of from about 1 to about 100 mg/kg.
Claim 4
Dependent Claim
18 words
The method as defined in claim 1 wherein said imidazole is in the form of its hydrochloride salt.
Claim 5
Independent Claim
31 words
A method of inhibiting arachidonic acid-induced platelet aggregation which comprises administering to a mammalian host in need thereof an effective amount of 1-(3-phenyl-2-propenyl)-1H-imidazole or a pharmaceutically acceptable acid addition salt thereof.
