Compounds of the class of spiro[norbornane-2,3'-piperidines], spiro[bicyclo[2.2.2]octane-2,3'-piperidines], and corresponding spiro-pyrrolidine derivatives which are unsubstituted at the ring nitrogen atom or substituted by neutral or basic radicals, and the pharmaceutically acceptable acid addition salts of these new compounds possess valuable pharmacological properties and are active ingredients for pharmaceutical compositions. In particular, these new compounds have an antiviral activity. Specific embodiments are (1RS,2RS,4SR)-spiro[norbornane-2,3'-piperidine]-hydrochloride and 1'-[2-(2-azaspiro[5.5]undec-2-yl)-ethyl]-spiro[bicyclo[2.2.2]octane-2,3'-p iperidine]-dihydrochloride.
