Thiazolidine derivatives of formula ##STR1## in which R, R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 have the meanings as defined in the specification, Q is CH or N and X is H or a pharmacologically acceptable cation derived from an inorganic or organic base limited to amino acids. These derivatives are obtained by condensing phthalic or quinolinic anhydride, possibly substituted in the ring, with the thiazolidine, optionally substituted, in an aprotic solvent. Said derivatives as well as the salts thereof possess a fluidizing mucosecretolytic action.
