First Claim
Patent Images
1. A method for commercial scale production under an inert atmosphere of a transdermal formulation comprising a therapeutically effective amount of a hormone, the method comprising the steps of:
- dissolving a polyalcohol in an amount between 1% and 10% by weight of the formulation and a permeation enhancer in an amount between 1% and 30% by weight of the formulation in an alkanol in an inert atmosphere to form a stirred solution;
adding the therapeutically effective amount of the hormone to the stirred solution to form a hormone solution;
adding purified water to the hormone solution to form a hydroalcoholic mixture;
adding to the hydroalcoholic mixture a sequestering agent in an amount between 0.03% and 0.09% by weight of the formulation to form a second solution;
adding a gelling agent to the second solution in an amount between 0.5% and 10% by weight of the formulation to form a primary compounding solution having viscosity between 16,000 and 40,000 cps; and
adding a pH regulator in an amount between 0.2% and 0.5% by weight of the formulation to the primary compounding solution to adjust the pH to between 5 and 7 to form the transdermal hormone formulation.

20. A method for producing under an inert atmosphere a 500 kilogram batch of a transdermal formulation comprising a therapeutically effective amount of a testosterone compound, the method comprising the steps of:
-
dissolving 5.0 kilograms of a testosterone compound, 25 kilograms of propylene glycol and 30 kilograms diethylene glycol monoethyl ether in 223 kg of stirred 200 proof ethanol to form a stirred solution; adding 168 kg purified water to the stirred solution to form a hydroalcoholic mixture; adding to the hydroalcoholic mixture while stirring 300 grams of edetate disodium dissolved in 10 kg purified water to form a second solution; adding 6.0 kilograms of Carbomer Carbopol 980 to the second solution to form a third solution having viscosity between 22,000 and 25,000 cps; adding 7.64 kilograms of triethanolamine to the third solution to adjust the pH to between 5 and 7 to form the transdermal testosterone formulation; and collecting about 500 kilograms of the transdermal testosterone formulation.
