A method for the prevention of diseases caused by thrombus or embolus. The method is to separately administer 2-acetoxy-5-(&#x3b1;-cyclopropylcarbonyl-2-fluorobenzyl)-4,5,6,7-tetrahydrothieno[3,2-c]pyridine or a pharmaceutically acceptable salt thereof, and aspirin, in their pharmacologically effective amounts, to a warm-blooded animal.

Method of treatment with coadministration of aspirin and prasugrel

A combination of 2-acetoxy-5-(&#x3b1;-cyclopropylcarbonyl-2-fluorobenzyl)-4,5,6,7-tetrahydrothieno[3,2-c]pyridine or a pharmaceutically acceptable salt thereof, and aspirin, which possess excellent inhibitory activity against platelet aggregation and thrombogenesis, and is useful for preventing or treating diseases caused by thrombus or embolus.

Medicinal compositions containing aspirin

A compound of a formula (1) and pharmacologically acceptable salts thereof:wherein Rrepresents hydrogen, halogen, alkyl or hydroxyl; Rrepresents hydrogen or halogen; Rrepresents hydrogen, alkyl, hydroxyl, carboxyalkyl, alkoxycarbonylalkyl, alkylsulfonyl, alkoxycarbonylalkylsulfonyl, craboxyalkylsulfonyl or carboxyalkylcarbonyl; each of Rand Rrepresents hydrogen, halogen, alkyl, carbamoyl, alkoxy, carboxyl, alkoxycarbonyl, monoalkylcarbamoyl or dialkylcarbamoyl; Rrepresents a heterocycle, hydrogen, alkyl, cycloalkyl, aralkyl, carboxyalkyl, alkoxycarbonyalkyl, aliphatic or aromatic acyl, carbamoyl, alkylsulfonyl, aryl, formimidoyl, 1-iminoalkyl, N-alkylforminidoyl or iminoarylmethyl; each of Rand Rrepresents hydrogen or alkyl; n represents 0, 1 or 2. The compound exhibits excellent activated blood coagulation factor X inhibitory activity and prevents or treats blood coagulation-related diseases.

Benzamidine derivatives

Acid addition salts of 2-acetoxy-5-(&agr;-cyclopropyl-carbonyl-2-fluorobenzyl)-4,5,6,7-tetrahydrothieno&lsqb;3,2-c&rsqb;-pyridine. The acid addition salts of tetrahydrothienopyridine derivatives of the present invention exhibit excellent oral absorption, metabolization into the active compound, and platelet aggregation-inhibiting effects, low toxicity, and excellent storage and handling stabilities, and are useful as medicaments, preferably preventive or therapeutic agents (particularly therapeutic agents) for diseases caused by a thrombus or an embolus, still more preferably preventive or therapeutic agents (particularly therapeutic agents) for thrombosis or embolism.

Acid addition salts of hydropyridine derivatives

Cyclic amino compounds

A cyclic amine derivative represented by the following formula: ##STR1## wherein R.sup.1 represents a substituted or unsubstituted phenyl group, R.sup.2 represents a substituted of unsubstituted C.sub.1 -C.sub.8 aliphatic acyl group, a substituted or unsubstituted benzoyl group or a C.sub.1 -C.sub.4 alkoxycarbonyl group, and R.sup.3 represents a substituted 3 to 7 membered saturated cyclic amino group which may form a fused ring; or pharmaceutically acceptable salts thereof. The compounds and salts have excellent platelet aggregation inhibitory action. They are useful for the treatment and prevention of such diseases as embolism, thrombosis or arteriosclerosis and for the preparation of pharmaceutical compositions for such uses.

Cyclic amine derivatives

Compounds of formula (I): ##STR1## wherein: R.sup.1 represents a saturated heterocyclic group attached to the bond or group represented by A through a ring carbon atom; R.sup.2a, R.sup.2b, R.sup.2c, R.sup.3a, R.sup.3b, R.sup.3c and R.sup.3d are hydrogen or various other groups or atoms; and A represents a single bond or an alkylene group having from 1 to 6 carbon atoms are serotonin 2 receptor antagonists and have the ability to inhibit the activity of squalene synthase. They can not only prevent and inhibit the development and progression of arteriosclerosis but can also inhibit thrombosis in arteriosclerotic lesions and can improve hemodynamics.

Diphenylethane compounds containing a saturated heterocyclic group,

Compounds of formula (I): ##STR1## [wherein: R.sup.1 is aryl; R.sup.2 is hydrogen, alkyl, alkoxy, halogen or cyano; R.sup.3 is a group of formula --B--NR.sup.4 R.sup.5, where R.sup.4 and R.sup.5 are independently hydrogen, alkyl or substituted alkyl or R.sup.4 and R.sup.5, together with the nitrogen to which they are attached, form a heterocycle, and B is alkylene or a group of formula --CH.sub.2 CH(OR.sup.6)CH.sub.2 --, where R.sup.6 is hydrogen, alkanoyl, substituted alkanoyl or arylcarbonyl, or a group of formula --D--R.sup.7, where D is a single bond or alkylene and R.sup.7 is a heterocycle; and A is alkylene; and pharmaceutically acceptable salts and esters thereof] are useful for the treatment and prevention of circulatory diseases and psychosis.
