The mean duration of action of the study medication (minutes). The mean (minutes) duration of therapeutic effect of study medications were naproxen (527.28 +/- 60.01), G. kola (454.09 +/- 55.49) and Celebrex (563.47 +/- 38.21) subgroup. The 2-way ANOVA with post hoc comparison of the mean duration of G. kola therapeutic action showed it was less than that of naproxen (p < 0.002) and Celebrex (p < 0.001). It was longer than the placebo (p < 0.001) as illustrated in Figure 3.
