Quote from the patent;
It's a total of 4 new RU58841 solutions; 0.5%, 1%, 2% and 5%. I'm posting the 2- and 5% solutions only. These have the same ingredients, but at different ratios. The percentage amounts stated are based on the total weight of the solution. The solutions are prepared by dissolving the various components in water, which means that you begin with water, and add everything else to it. The drug should be added when the vehicle is prepared.
Formula - 2% solution
- 54% Demineralized water
- 40% Ethanol (96%)
- 2% Polyethoxylated hydrogenated castor oil (BASF Cremophor RH 410)
- 2% Vinylimidazolium methochloride/vinylpyrrolidone copolymer (BASF Luviquat FC 550)
- 2% RU58841
Formula - 5% solution
- 27% Demineralized water
- 63% Ethanol (96%)
- 2.5% Polyethoxylated hydrogenated castor oil (BASF Cremophor RH 410)
- 2.5% Vinylimidazolium methochloride/vinylpyrrolidone copolymer (BASF Luviquat FC 550)
- 5% RU58841
[0009]Due to the teratogenicity of antiandrogens, intrinsic to the substances, with an influence on sex differentiation in the late stage of pregnancy, the substances mentioned cannot be used in the form of conventional aqueous/alcoholic hair lotions because of the occurrence of precipitates of the substances at the application site after evaporation of the solvent and the associated toxicological risk of transfer of the substance to pregnant women. Furthermore, delayed release of the active compounds over a relatively long period of time, in order to avoid high systemic concentrations of the active substance and the associated occurrence of systemic antiandrogenic effects, is not guaranteed by conventional formulation for application to the scalp.
[0010]In order to make the antiandrogenic active compounds in the above-mentioned references available for a reliable and effective treatment, it was therefore necessary to discover compositions which do not have the disadvantages described for conventional scalp treatment compositions.

[0088]The treatment of androgenic alopecia can be carried out reliably and effectively with the compositions according to the invention. This is an extremely important finding, in view of the poor treatment results to date.
