The invention relates to the use of an NK-1 receptor antagonist for the treatment or prevention of benign prostatic hyperplasia (BPH). The preferred NK-1 receptor antagonists are compounds of the general formula (I) wherein the meanings of R, R1, R2, R2', R3, R4 are explained in the specification and the pharmaceutically acceptable acid addition salts and the prodrugs thereof. Preferred compounds are 2-(3,5-bis-trifluoromethyl-phenyl)-N-methyl-N-(6-morpholin-4-yl-4-o-tolyl-pyridin-3-yl)-isobutyramide,3-(3,5-bis-trifluoromethyl-phenyl)-N-methyl-N-[6-(4-methyl-piperazin-1-yl)-4-o-tolyl-pyridin-3-yl]-isobutyramide,2-(3,5-bis-trifluoromethyl-phenyl)-N-[6-(1,1-dioxo-1.lambda.6-thiomorpholin-4-yl)-4-o-tolyl-pyridin-3-yl]-N-methyl-isobutyramide and 2-(3,5-bis-trifluoromethyl-phenyl)-N-[6-(1,1-dioxo-1.lambda.6-thiomorpholin-4-yl)-4-(4-fluoro-2-methyl-phenyl)-pyridin-3-yl]-N-methyl-isobutyramide. The invention also relates to pharmaceutical composition comprising one or more such NK-1 receptor antagonists and a pharmaceutically acceptable excipient for the treatment and/or prevention of benign prostatic hyperplasia. |
