Abstract

Iso- and heterocyclic phenylsulphonamides can be prepared by reaction of corresponding iso- and heterocyclic amines with phenylsulphonic acid derivatives. The iso- and heterocyclic phenylsulphonamides have thrombocyte aggregation-inhibiting and thromboxane A.sub.2 antagonist action and can be used in medicaments.
