- Pharmaceutical formula
-
The present invention concerns a pharmacological vehicle or carrier system, which makes possible administration of the active ingredient with a high absorption thereof in the blood circulation of the patient treated therewith, in particular also in the case of oral administration. The pharmacological vehicle system according to the invention comprises ultrafine particles of a reaction product of a reactive derivative of an at least dibasic inorganic acid or an alkane-carboxylic acid having 2 or 3 carboxyl groups and optionally one or two hydroxy groups, wherein one bond of the dibasic inorganic acid or one carboxy group of the alkane-carboxylic acid is bonded to a pharmacological active ingredient containing a hydroxy group, SH group and/or a primary or secondary amino group having a ractive hydrogen atom on this group, and the other bond is bonded to the free hydroxy group of a glycerolipid having at least one free hydroxy group on the glycerol. The invention further concerns these reaction products and a process for the preparation of ultrafine particles of these reaction products.
