Abstract:
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.
