BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to remedies for prostate diseases, endometriosis and obesity comprising, as active ingredient, droloxifene having the chemical structure represented by the following formula, ##STR1## or a pharmaceutically acceptable salt thereof.
BACKGROUND OF THE INVENTION
Droloxifene is a known compound disclosed in U.S. Pat. No. 5,047,431 in which it is disclosed as an anti-tumor agent, particularly for treatment and prevention of cancer of the breast. Droloxifene is also useful for the relief of bone diseases caused by the deficiency of estrogen or the like, which are often observed in women after menopause or those with the ovaries removed. U.S. Pat. No. 5,254,594.
Gill-Sharma, et al., J. Reproduction and Fertility (1993) 99, 395, disclose that tamoxifen at 200 and 400 mg/kg/day reduces the weights of the testes and secondary sex organs in male rats.
Neubauer, et al., The Prostate 23: 245 (1993) teach that raloxifene treatment of male rats produced regression of the ventral prostate.
SUMMARY OF THE INVENTION
This invention provides a method for treating a condition or disease selected from endometriosis, obesity, benign prostatic hypertrophy and prostatic carcinoma in mammals which comprises administering to said mammal an amount of droloxifene or a pharmaceutically acceptable salt thereof which is effective in treating said condition or disease.
DETAILED DESCRIPTION OF THE INVENTION
The preparation of droloxifene ne) and pharmaceutically acceptable salts thereof is described in U.S. Pat. No. 5,047,431 which is incorporated herein by reference.
As used in this application, "prostatic disease" means benign prostatic hyperplasia or prostatic carcinoma. "Treating" means curing, alleviating the symptoms of or preventing the onset of a disease or condition.
The remedies for the prostatic diseases, endometriosis and obesity of this invention comprise, as active ingredient, droloxifene or a salt thereof. The pharmaceutically acceptable salts of droloxifene are salts of non-toxic type commonly used, such as salts with organic acids (e.g., formic, acetic, citric, maleic, tartaric, methanesulfonic, benzenesulfonic or toluenesulfonic acids), inorganic acids (e.g. hydrochloric, hydrobromic, sulfuric or phosphoric acids), and amino acids (e.g., aspartic or glutamic acids). These salts may be prepared by the methods known to chemists of ordinary skill.
The remedies for the diseases and conditions of this invention may be administered to animals including humans orally or parenterally in the conventional form of preparations, such as capsules, microcapsules, tablets, granules, powder, troches, pills, suppositories, injections, suspensions and syrups.
The remedies for the diseases and conditions of this invention can be prepared by the methods commonly employed using conventional, organic or inorganic additives, such as an excipient (e.g., sucrose, starch, mannitol, sorbitol, lactose, glucose, cellulose, talc, calcium phosphate or calcium carbonate), a binder (e.g., cellulose, methylcellulose, hydroxymethylcellulose, polypropylpyrrolidone, polyvinylprrolidone, gelatin, gum arabic, polyethyleneglycol, sucrose or starch), a disintegrator (e.g., starch, carboxymethylcellulose, hydroxypropylstarch, low substituted hydroxypropylcellulose, sodium bicarbonate, calcium phosphate or calcium citrate), a lubricant (e.g., magnesium stearate, light anhydrous silicic acid, talc or sodium lauryl sulfate), a flavoring agent (e.g., citric acid, menthol, glycine or orange powder), a preservative (e.g., sodium benzoate, sodium bisulfite, methylparaben or propylparaben), a stabilizer (e.g., citric acid, sodium citrate or acetic acid), a suspending agent (e.g., methylcellulose, polyvinylpyrrolidone or aluminum stearate), a dispersing agent (e.g., hydroxypropylmethylcellulose), a diluent (e.g., water), and base wax (e.g., cocoa butter, white petrolatum or polyethylene glycol). The amount of the active ingredient in the medical composition may be at a level that will exercise the desired therapeutica
