The invention relates to a form of administration for the controlled releasing of the active substance 3-(2-dimethylaminomethyl cyclohexyl) phenol, preferably (1R,2R)-3-(2-dimethylaminomethyl cyclohexyl) phenol, or one of the pharmaceutically acceptable salts thereof. Said form of administration (i) in vivo reaches the peak plasma level of the active substance after 2 to 10 h, and/or (ii) in vitro releases 3.0 to 37 percent by weight of the active substance originally contained therein after 05 hours, 5.0 to 56 percent by weight after 1 hour, 10 to 77 percent by weight after 2 hours, 15 to 88 percent by weight after 3 hours, at least 30 percent by weight after 6 hours, at least 50 percent by weight after 12 hours, at least 70 percent by weight after 18 hours, and at least 80 percent by weight after 24 hours when measured according to the European pharmacopoeia by means of a blade mixer in buffer solution at a pH value of 6.9 (preferably 900 ml), a temperature of 37 °C, and 75 U/min.
