Dogs were randomly assigned to receive gabapentin (20 mg\/kg orally) and trazodone (8 mg\/kg orally) followed by maintenance isoflurane or maintenance isoflurane alone. For their second event, dogs received the other treatment. The MAC was determined using an iterative bracketing technique with electric stimulation. Hemodynamic variables and vital parameters were assessed throughout the anesthetic episode. The effect of treatment on outcome variables was analyzed by use of a paired <jats:italic>t<\/jats:italic> test (<jats:italic>P<\/jats:italic> &lt; .05).<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sc_a3\">\n<jats:title>RESULTS<\/jats:title>\n<jats:p>The mean \u00b1 SD MAC of isoflurane in dogs was significantly lower with gabapentin and trazodone premedication and isoflurane (0.625 \u00b1 0.18%) compared with isoflurane alone (0.95 \u00b1 0.14%). The mean MAC of isoflurane reduction was 0.33 \u00b1 0.04%. Heart rate was decreased but still within normal limits in premedicated dogs.
