The invention relates to freeze-dried soft, flexible and continous matrix of low-molecular weight hyaluronic acid or salt thereof, in which the molecular weight of the hyaluronic acid is preferably between 50 000 and 200 000 Da, containing at least one peptide or protein. It also relates to a pharmaceutical composition in the form of a layer which is characterised by this freeze-dried low-molecular weight hyaluronic acid containing at least one peptide or protein. The drug is preferably chosen from at least one of GH, IGF-I, IGF-II and/or EGF and could be mixtured with an antibiotic agent. The process for the manufacture of this matrix and the use of the pharmaceutical composition for the manufacturing of a drug for wound healing is claimed. The invention discloses a method for accurately obtaining a predetermined dosage of a topically administerable drug which is characterised by freeze-drying a water solution of low-molecular weight hyaluronic acid and the peptide or protein to form a layer.
