Cats:
For moderate-deep sedation and restraint of cats Medetor should be administered at a dosage of 50 – 150 µg medetomidine hydrochloride /kg bw (corresp. to 0.05 – 0.15 ml Medetor/kg bw).
For anaesthesia Medetor should be administered at a dosage of 80 µg medetomidine hydrochloride / kg bw (corresp. to 0.08 ml Medetor / kg bw) and 2.5 to 7.5 mg ketamine / kg bw. Using this dosage anaesthesia occurs within 3 – 4 minutes and is apparent for 20 – 50 minutes. For longer lasting procedures administration has to be repeated by using ½ of the initial dose (i.e. 40 µg medetomidine hydrochloride (corresp. to 0.04 ml Medetor / kg bw) and 2.5 - 3.75 mg ketamine / kg bw) or 3.0 mg ketamine / kg bw alone. Alternatively, for longer lasting procedures anaesthesia may be extended by use of the inhalation agents isoflurane or halothane, with oxygen or oxygen/nitrous oxide. See section 4.5.
Advice on correct administration: Animals should be fasted 12 hours before anaesthesia.
