Figure 2.

Thermal threshold in relation to plasma concentrations. The green graph (circles) shows the thermal threshold (°C) after administration of 0.2 mg/kg levomethadone intramuscularly. The red graph (triangles) illustrates the thermal threshold (°C) of the 4 saline treatments. The blue graph (squares) demonstrates the plasma levomethadone concentration (ng/mL). Note the time points of significant threshold rise (stars). All data are displayed as Mean ± SD of the 6 dogs.
