The process for making crystals of a medicinally effective ingredient having a predetermined average particle size in a predetermined size range and a maximum particle size that does not exceed a predetermined maximum value, includes subjecting a supersaturated solution containing the medicinally effective ingredient to a wet milling by a wet milling apparatus while crystallizing, in order to obtain a primary particle suspension. Crystals obtained according to this process and pharmaceutical preparations containing them are also described.

The process for making crystals of a 11&bgr;-benzaldoxim-estra-4,9-diene derivative having a predetermined average particle size in a predetermined size range and a maximum particle size that does not exceed a predetermined maximum value, includes subjecting a supersaturated solution containing a special 11&bgr;-benzaldoxim-estra-4,9-diene derivative of formula (I) to a wet milling by a wet milling apparatus while crystallizing, in order to obtain a primary particle suspension. Crystals obtained according to this process and pharmaceutical preparations containing them are also described.
The methods provided herein comprise administering a selective progesterone receptor modulator (SPRM) during a first dosing period and at least one progestogen during a second dosing period. The dosing periods can run concomitantly or sequentially with or without a period where neither the SPRM nor the progestogen is administered.
