New chemical compounds, which are pyrrolidinoethylamine amides, in the form of free bases and salts thereof, which are useful as antitussives, pharmaceutical compositions thereof, and method of treating therewith. In the form of their salts, the compounds have the formula: ##STR1## wherein ##STR2## is an acyl radical of a phenylacetic,.alpha.-phenyl-.alpha.-ethylacetic, diphenylacetic, benzilic, .alpha.-lower-alkoxy-.alpha.,.alpha.-diphenylacetic, 10-phenothiazinecarboxylic, benzoic, halobenzoic, 3-coumarincarboxylic, 9-xanthenecarboxylic, salicylic, cresotic, halocresotic, lower-alkoxybenzoic, phenoxyacetic, phenoxyisobutyric, halophenoxyisobutyric, cinnamic, or 9-fluorene carboxylic acid, and wherein R'H represents an inorganic or organic acid, and wherein R may be, for example, a substituted aromatic ring of the formula: ##STR3## wherein R.sub.1 and R.sub.2 may independently be lower-alkyl, lower-alkoxy, hydrogen, lower-alkenyloxy, or lower-alkynyloxy, and X may be hydrogen or halogen. Medicaments containing these active principles may be used, inter alia, in the treatment of coughs and respiratory complaints.
