Description
Summary:The antinociceptive effects of buprenorphine have been reported in dogs and cats. This study evaluated changes in the mechanical nociceptive threshold and the sedative effects of buprenorphine, acepromazine and its combination in cats, determined by the same observer using a nociceptive threshold testing device and DIVAS, respectively. Eight animals were previously conditioned to the procedures. After four baseline measurements, 0.02mg [kg.sup.-1] of buprenorphine, 0.06mg.[kg.sup.-1] of acepromazine, or 0.01mg [kg.sup.-1] of buprenorphine with 0.03mg [kg.sup.-1] of acepromazine were administered intramuscularly in a blinded and experimental study using a Latin square design within a one week interval between treatments. The antinociceptive and sedative effects were evaluated at 15, 30, 45 minutes and 1, 2, 3, 4, 6, 8 and 12 hours post treatment. The nociceptive threshold increased significantly only after the combination buprenorphine-acepromazine (between 45 minutes and 1 hour). Regarding sedation, the use of acepromazine and the combination of both were associated with significantly higher DIVAS values from 15 minutes to 4 hours and 1 5 minutes to 3 hours post treatment, respectively. No increase in these values was noted with the use of buprenorphine. It was concluded that it could not be verified the superiority of neuroleptanalgesia over the use of drugs alone
