Control of selective estrogen receptor modulators
View Patent ↗The treatment of an estrogen sensitive condition by the administration of a selective estrogen receptor modulator is improved by additionally administering a progestationally active compound to the recipient. The additional agent can express both progestational and androgenic activity or an androgenically active material can be employed, if desired. Additionally, clomiphene in an array of isomeric ratios (EN:ZU) can be used alone for prevention of osteoporosis, maintenance of a healthful blood lipid profile, and prevention of breast tumors, or to sustain amenorrhea.
1. In a method of achieving contraception in a premenopausal human female by administering to the female a contraception effective amount of a contraceptive agent, the improvement which comprises said agent being a combination of a contraception effective amount of a Selective Estrogen Receptor Modulator and an agent which exhibits progestogenic activity, wherein the amount of the agent which exhibits progestogenic activity is effective to ameliorate or eliminate the bleeding side effects of the Selective Estrogen Receptor Modulator.
2. The method of claim 1 wherein the Selective Estrogen Receptor Modulator is clomiphene.
3. The method of claim 1 wherein the Selective Estrogen Receptor Modulator is a benzothiophene.
4. The method of claim 1 wherein the agent which exhibits progestogenic activity is an antiprogestin.
5. The method of claim 4 wherein the antiprogestin is a progesterone receptor antagonist.
6. The method of claim 5 wherein the Selective Estrogen Receptor Modulator is clomiphene.
7. The method of claim 5 wherein the Selective Estrogen Receptor Modulator is a benzothiophene.
8. The method of claim 4 wherein the amount of antiprogestin is that sufficient to maintain the blood estrogen concentration in the range of about 25 to 125 pg/ml.
9. The method of claim 8 wherein the amount of antiprogestin is that sufficient to maintain the blood estrogen concentration in the range of about 60 to 90 pg/ml.
10. The method of claim 1 wherein the agent which exhibits progestogenic activity expresses both androgenic and progestogenic activity.
11. The method of claim 10 wherein the agent which exhibits progestogenic activity comprises the combination of an androgen and a progestin.
12. The method of claim 10 wherein the agent which exhibits progestogenic activity is a single material which expresses both activities.
13. The method of claim 12 wherein the agent which exhibits progestogenic activity is danazol or levonorgestrel.
