Process for the production of dry pharmaceutical forms and the thus obtained pharmaceutical compositions
First Claim
1. A process for the production of a solid dispersion of 1 to 20% by weight of a surface active agent, 10 to 60% by weight of at least one therapeutic agent selected from the group consisting of progesterone and a mixture of progesterone and estradiol or an ester or ether thereof in a hydrophilic carrier having enhanced solubility in an aqueous media comprising dissolving the therapeutic agent in a volatile organic solvent containing a very hydrophilic polymer and without strong heat or vacuum evaporating the solvent to dryness to form a co-precipitate of therapeutic agent and hydrophilic polymer.

Abstract
A process for the production of a solid dispersion of at least one therapeutic agent in a hydrophilic carrier having enhanced solubility in an aqueous media comprising dissolving at least one therapeutic agent in a volatile organic solvent containing a very hydrophilic polymer and evaporating the solvent to dryness to form a co-precipitate of therapeutic agent and hydrophilic polymer and the resulting products and their therapeutic method of use.
