Linear regression analyses of Q_(tot)over time of pseudoephedrine vs amygdalin and their ratios was adopted for correlation evaluation.RESULTS: At 1, 2, 4, 6, and 8 h, the Q_(tot),T_(tot)and Kp of pseudoephedrine showed a good correlation with that of amygdalin.CONCLUSION: There was a small difference in theratios of Q_(tot), T_(tot)and Kp between pseudoephedrine and amygdalin, and a correlation between them.展开更多
