Selected substituted 1-phenyl-2-pyrrolidin-2-yl-ethanols and their pharmacologically-acceptable acid-addition salts are useful as analgesics in human and veterinary medicine. Such compounds are prepared by reducing corresponding substituted 1-phenyl-2-pyrrolidin-2-yl ethanones and are formulated into medicinal compositions suitable for administration.
2-Benzylpyrrolidines bearing from 1 to 4 nuclear substituents on the benzyl ring are pharmacologically active, particularly on the CNS, on blood pressure and on pain sensation for warm-blooded animals. They are synthesized, e.g., by reducing appropriate 2-benzylpyrrolidines and are formulated into medicament compositions according to established conventional techniques.
