The gist of the invention is a new pharmaceutical composition which contains a lipid phase,composed as follows: 1.0-40.0% solid lipids; 0.1 -10.0% roxithromycin; 1.0-10.0% surfactants, and optionally 0-20.0% of preservatives, plus complementing water to make 100%. The invention further concerns application of the pharmaceutical composition to produce medicinal products targeted at treating androgenic hair loss and/or common acne. The preparation method of the pharmaceutical composition comprises the following stages: the aqueous phase and components of the lipid phase are heated separate to the temperature of 75-85°C; both phases are combined and homogenised, and the obtained microemulsion is cooled down to the room temperature; after the cooling, preservatives are added. |
