Abstract: A pharmaceutical preparation comprising:(a) isosorbide dinitrate as active ingredient(b) a solvent for isosorbide dinitrate(c) an ointment consistency agent(d) an emulsifying agent(e) water, and(f) possibly customary preservatives, antioxidants, buffers and/or odorants;where the weight ratio of water: consistency agent including emulsifying agent: solvent is 30 to 80: 3 to 35: 3 to 35, the amount of emulsifying agent is from 0% to 15% by weight and the amount of isosorbide dinitrate is from 2% to 20% by weight. The preparation has an ointment-like consistency and is administered topically to the skin, where it has a high adsorption rate and a long duration of response.

Abstract: Supersaturated aqueous to organic solvent solution of isosorbide dinitrate, process of preparation at elevated temperatures, and use of the supersaturated solutions for the production of infusion solutions.
