This invention relates to derivatives of perhydroisoindol of formula: ##STR1## in which the radicals R are hydrogen atoms or together form a bond, the symbols R.sub.2 are phenyl radicals which can be substituted by a halogen atom or a methyl radical in position 2 or 3, R.sub.3 is a halogen atom or a hydroxy radical, R.sub.4 is H or halogen if R.sub.3 is halogen, in their isomer forms, or mixture thereof, and possibly also their salts when they exist, and preparation thereof. The derivatives of the invention are particularly interesting as P substance antagonist.
本发明涉及公式为:##STR1##的过氢化异
