- b. a first compound;
- and
- c. a second compound;
- and
- wherein the first compound and second compound are different, and each is selected from the group consisting of DMSO, diethyleneglycol monoethyl ether, diethyl sebacate, diisopropryl adipate, dipropylene glycol, polyethylene glycols, isopropanol, t-butanol, polyethylene glycol dodecyl ether, cetyl alcohol, mineral oil, caprylic triglyceride, capric triglyceride, caprylic/capric triglycerides, and stearic acid, or a combination thereof.

- a. 0.01% to 20% (w/w) of the at least one active agent is selected from the group consisting of tamoxifen, raloxifene, toremifene, N-desmethyl-tamoxifen, iodoxifene, droloxifene, clomefine, ormeloxifene, lasofoxifene, ospemifene, nafoxidine, fulvestrant, letrozole, anastrozole, and exemestane, and salts and solvates thereof, or a combination thereof;
- and
- wherein the first compound comprises 10% to 90% (w/w) of diethyleneglycol monoethyl ether;
- and the second compound comprises 5% to 80% (w/w) of a penetration enhancer selected from the group consisting of DMSO, diethyl sebacate, diisopropryl adipate, dipropylene glycol, polyethylene glycols, isopropanol, t-butanol, polyethylene glycol dodecyl ether, cetyl alcohol, mineral oil, caprylic triglyceride, capric triglyceride, caprylic/capric triglycerides, and stearic acid, or a combination thereof;
- or
- wherein the first compound comprises 10% to 90% (w/w) of DMSO;
- and the second compound comprises 5% to 80% (w/w) of a penetration enhancer selected from selected from the group consisting of diethyleneglycol monoethyl ether, diethyl sebacate, diisopropryl adipate, dipropylene glycol, polyethylene glycols, isopropanol, t-butanol, polyethylene glycol dodecyl ether, cetyl alcohol, mineral oil, caprylic triglyceride, capric triglyceride, caprylic/capric triglycerides, and stearic acid, or a combination thereof, or a combination thereof.
