(EN) Thienyl-, furyl- and pyrrolyl-sulfonamides, pharmaceutically-acceptable salts of sulfonamides, formulations of salts and the sulfonamides, and methods for modulating or altering the activity of the endothelin family of peptides using the formulations and sulfonamides are provided. In particular, formulations of sodium salts of N-(isoxazolyl)thienylsulfonamides, N-(isoxazolyl)furylsulfonamides and N-(isoxazolyl)pyrrolylsulfonamides are provided. A process of preparing an alkali metal salt of a hydrophobic sulfonamide is provided. The process includes the step of dissolving a free sulfonamide in an organic solvent in the presence of a saturated alkali metal salt solution and recovering the formed sulfonamide salt from the organic phase.(FR) L'invention concerne des thiényl-, furyl- et pyrolylsulfamides, des sels pharmaceutiquement acceptables de sulfamides, des formulations de sels et des sulfamides, ainsi que des procédés visant à moduler ou altérer l'activité des peptides appartenant à la famille de l'endothéline au moyen des formulations et des sulfamides en question. En particulier, l'invention concerne des formulations de sels de sodium de N-(isoxazolyl)thiénylsulfamides, N-(isoxazolyl)furylsulfamides, et N-(isoxazolyl)pyrolylsulfamides. L'invention concerne aussi un procédé d'élaboration de sel de métal alcalin à partir d'un sulfamide hydrophobe. Ce procédé consiste à dissoudre un sulfamide libre dans un solvant organique, en présence d'un soluté salin de métal alcalin saturé, et à extraire de la phase organique le sel de sulfamide ainsi formé.
