Furthermore, the invention relates to a method for preparing said pharmaceutical composition and also the use thereof, preferably in paediatrics, for the manufacture of a drug that can be used to treat moderate-to-severe pain, inflammation, fever and/or other illnesses in which ibuprofen and/or codeine are traditionally used principally as analgesic. The composition of the invention exhibits good stability after three years under different temperature and relative humidity conditions.
