Abstract [en]

The pharmacokinetics and effects of the opioid methadone on behaviour, arterial blood pressure, heart rate and haematocrit were studied in goats. Two goats received methadone (0.2 mg/kg) intravenously and the terminal half-life was 88 and 91 min, the volume of distribution 8.4 and 6.1 L/kg, and clearance 86 and 123 mL/min/kg. In a crossover study eight goats received methadone (0.6 mg/kg) or 0.15 M NaCl subcutaneously (SC). After SC administration bioavailability was complete and the terminal half-life was 215 +/- 84 min (mean +/- SD), T-max 31 +/- 15 min and C-max 45 +/- 11 ng/mL. Blood pressure and haematocrit increased while heart rate did not change. The goats did not ruminate and they climbed, scratched, gnawed and showed tail-flicking after SC methadone in contrast to NaCl administration. The use of methadone in goats may be restricted due to the inhibition of rumination and the rather short half-life.
