Abstract
The invention provides water-soluble salts of tienilic acid, 2,3-dichloro-4-(2-thienylcarbonyl)-phenoxyacetic acid, and amino acids of the formula ##STR1## in which n is an integer of 1 to 5 and R represents a basic nitrogenous group, preferably an amino group or guanidino group. These salts, unlike the parent acid are water-soluble and are of good biodisponibility and may be used in injectable form, e.g. for emergency treatment.
