Abstract: The invention concerns the use of diphenylamine as a detoxicant for halogen-containing drugs administered to animals, such as carbon tetrachloride, hexachlorophene, bithionol sulfoxide, etc. The diphenylamine may be administered separately to the animal or simultaneously with the halogen-containing drug in the form of a therapeutic composition.

Abstract: This invention relates to 2,3-dihydro-imidazo[2,1-b]-thiazole derivatives of the formula: ##STR1## in which R represents a phenyl or substituted phenyl group,R.sub.1 represents a hydrogen atom or a phenyl substituted with a halogen atom or a C.sub.1-4 alkoxy group,R.sub.2, r.sub.3, r.sub.4 and R.sub.5, which may be the same or different, represent each a hydrogen atom, a C.sub.1-4 alkyl group or a phenyl radical,R.sub.1, r.sub.2, r.sub.3, r.sub.4 and R.sub.5 not being simultaneously hydrogen when R represents a phenyl group or a phenyl group substituted with a halogen atom or a nitro group, and their pharmaceutically acceptable acid addition salts.Said compounds have an anti-inflammatory and analgesic activity.
