Table 3.

ED₅₀ values of the antinociception produced by Dezocine and Morphine.

Compounds	Antinociception ED₅₀ (mg/kg)
Compounds	Hot plate test	Abdominal constriction test	Formalin test Phase I Phase II
Dezocine	—	0.2 (0.1–0.2)	0.4 (0.2–1.0)	0.4 (0.2–0.9)
Morphine	6.9 (5.6–8.5)^a	0.8 (0.5–1.2)^a	5.1 (4.3–5.9)^b	3.1 (2.8–3.3)^b

The antinociceptive ED₅₀ values were calculated from data obtained at 15 min after drug administration. In parentheses are 95% confidence limits.

^a,bThe data of morphine associated with hot-plate test, abdominal constriction test and formalin test were cited from our previous data^34,35.
