A method for producing antibiotic composites is described, which is characterized in that a salt, which can be subjected to plastic deformation and which consists of at least one cationic component of a protonated antibiotics base from the groups of aminoglycoside antibiotics, the lincosamide antibiotics and the tetracycline antibiotics and of at least one anionic components from the group of organic sulfates and/or organic sulfonates and/or fatty acid esters, is used as a binding agent for the fixation of inorganic composite components and/or possibly organic composite components and possibly for the molding of the composites while adding water, especially through pressing, extrusion, rolling, calendering and grinding processes.
