	ED₅₀ (log mol)	Area Under Curve (arbitrary unit)
NE	−7.73 ± 0.07	129.74 ± 13.54
120 mmol of K⁺	−7.56 ± 0.07	70.22 ± 6.06*
NE/thiopental	−7.61 ± 0.05	83.86 ± 4.45*
NE/miconazole	−7.64 ± 0.06	83.84 ± 6.25*

One-way analysis of variance followed by Newman–Keuls multiple comparisons test was used, *p < .05, versus NE.
