Abstract:
A process for making a pharmaceutical composition suitable for delivery through mucosal membranes comprising:a) preparing a proteinic pharmaceutical agent composition in micellar form in an aqueous medium which has an alkali metal salicylate in a concentration of from 1 to 10 wt./wt. % of the aqueous micellar pharmaceutical agent composition, an alkali metal lauryl sulphate in a concentration of from 1 to 10 wt./wt. % of the aqueous micellar pharmaceutical agent composition and a pharmaceutically acceptable edetate in a concentration of from 1 to 10 wt./wt. % of the aqueous micellar pharmaceutical agent composition;b) slowly adding the micellar proteinic pharmaceutical agent composition, while mixing vigorously, to at least one absorption enhancing compound, while continuing to mix vigorously, said absorption enhancing compounds being selected from the group consisting of lecithin, hyaluronic acid, pharmaceutically acceptable salts of hyaluronic acid, octylphenoxypolyethoxyethanol, glycolic acid, lactic acid, chamomile extract, cucumber extract, oleic acid, linolenic acid, borage oil, evening of primrose oil, trihydroxy oxo cholanylglyine, glycerin, polyglycerin, lysine, polylysine, triolein and mixtures thereof, wherein the amount of each absorption enhancing compound is present in a concentration of from 1 to 10 wt./wt. % of the total formulation, and the total concentration of alkali metal salicylate, alkali metal lauryl sulphate, edetate and absorption enhancing compounds is less than 50 wt./wt. % of the formulation.
