A pharmaceutical liquid composition containing the Pirfenidone in a very high concentration of more or less 25% by weight can be obtained by dissolving the Pirfenidone in diethylene glycol monoethyl ether. Even when the liquid medicinal compositions are stored for a long period of time, the Pirfenidone will not be recrystallized with a good chemical and physical stability. Furthermore, the liquid compositions are little irritating to the wounds on the mucous membrane of the skin and suitable for the manufacture of pharmaceutical formulations to be administered either via the oral, percutaneous, nasal or vaginal routes or by means of spray, patch, inhalation, injection or intravenous drip.

Solubility, absorption, and permeability of drugs upon oral administration are improved when the drugs are mixed and/or complexed with water-miscible organic solvents. Illustratively, the absorption of a heparin-deoxycholic acid conjugate upon oral administration is increased by mixing and/or complexing this conjugate with dimethyl sulfoxide. Other illustrative water-miscible organic solvents include N-methylpyrrolidone, polyoxyl 35 castor oil, diethylene glycol monoethyl ether, and benzoic acid.

The invention belongs to the technical field of water treatment, and particularly relates to sustained-release nano-calcium peroxide materials, preparation thereof, and a method for removing chlorohydrocarbon and benzene series from underground water by strengthening and activating the sustained-release nano-calcium peroxide materials through ferrous sulfide. By taking calcium chloride, hydrogen peroxide with the mass fraction being 30% and ammonium hydroxide with the mass fraction being 30% as raw materials and by adding different dispersing agents, an irreversible coagulation phenomenon is avoided in the synthesis process, then by adding different macromolecular polymers such as polyethylene glycol 400 (PEG400), polyvinyl alcohol (PVA) and diethylene glycol monoethyl ether (DEGMME), a film is formed on the surface of nCaO2, and through processes such as washing with water and ethyl alcohol and vacuum drying, the sustained-release nano-calcium peroxide advanced oxidation materials embedded with the various macromolecular polymers are obtained. By applying the oxidation materials, the purposes of efficient and lasting treatment of pollutants and lowering of the repair cost of the underground water in contaminated sites are achieved.
