The present invention provides a method of minimizing the uterotrophic effect of non-steroidal antiestrogen compounds of formula II <CHEM> wherein either R<4> is H or a lower alkyl radical and R<5> is a lower alkyl radical, or R<4> and R<5> are joined together with the adjacent nitrogen atom to form a heterocyclic radical; R<6> is H or a lower alkyl radical; R<7> is H, halo, OH, a lower alkyl radical, or is a buta-1,3-dienyl radical which together with the adjacent benzene ring forms a naphthyl radical; R<8> is H or OH; and n is 2; or a pharmaceutically acceptable salt thereof, wherein said formula II compound is administered to a woman for the treatment or prevention of breast carcinoma, comprising concurrently or sequentially administering to said woman a compound of formula I <CHEM> wherein R<1> and R<3> are independently hydrogen, -CH3, -CO-(C1-C6 alkyl), or -CO-Ar, in which Ar is optionally substituted phenyl; and R<2> is selected from the group consisting of pyrrolidino, hexamethyleneimino, and piperidino; or pharmaceutically acceptable salt or solvate thereof. The present invention further provides pharmaceutical compositions comprising a compound of formula I and a compound of formula II together with a pharmaceutically acceptable carrier, excipient, or diluent. |
