    • A sulfonamide derivative of the general formula:

      wherein, R¹ represents

      (i) COOR¹¹,
      (ii) CH₂OR¹² or
      (iii) CONR¹³R¹⁴,
      wherein
      R¹¹ represents a carbocyclic ring unsubstituted or substituted by an alkyl or alkoxy group of from 1 to 4 carbon atom(s) or halogen atom, or steroid,
      R¹² represents a hydrogen atom or COR¹⁵,
      R¹³ and R¹⁴ each represent a hydrogen atom or alkyl group of form 1 to 4 carbon atom(s) or NR¹³R¹⁴ represents an amino acid residue or heterocyclic ring, or
      R¹⁵ represents an alkyl group of from 1 to 4 carbon atom(s) or phenyl group,


      wherein

      represents


      Ba represents

      (i) -CH₂-CH₂-(CH₂)m- (Ba-1),
      (ii) cis-CH=CH-(CH₂)m- (Ba-2),
      (iii) -CH₂-O-(CH₂)m- (Ba-3),
      (iV) -S-(CH₂)m- (Ba-4) or
      (V)
      wherein m represents an integer of from 1 to 6, and the configuration of a double bond is E, Z or EZ and a phenylene group represetns an o-, m- or p-phenylene group in the formula (Ba-5),
      R 2a represents a bond or an alkylene group of from 1 to 4 carbon atom(s),
      R 3a represents a carbocyclic or heterocyclic ring unsubstituted or substituted by from one to three of an alkyl group of from 1 to 4 carbon atom(s), alkoxy group of from 1 to 4 carbon atom(s), hydroxy group, carboxyl group, ciano group, halogen atom or nitro group, or
      R 2a represents an alkyl group of from 1 to 12 carbon atom(s) together with R 3a,
      cyclodextrin clathrates thereof, or non-toxic salts thereof in case that NR¹³R¹⁴ represents an amino acid residue, possess an antagonistic activity on TXA₂, in particular, inhibit blood platelet aggregation and contraction of artery, and are, therefore, useful for prevention and/or treatment of inflammation, hypertension, thrombus, cerebral apoplexy, asthma, cardiac infarction, angina pectoris, cerebral infarction and death by aucte cardiac diseases in mammales, in particular in humans, which are induced by thromboxane A₂.
