Effect of aspirin (Asp) and aspirin after loxoprofen-trans-OH (Lox → Asp) addition on platelet aggregation threshold index (PATI). Loxoprofen-trans-OH concentration of (a): maximum concentration after taking loxoprofen at a dose of 60 mg, (b): the concentration 6 h after taking loxoprofen at a dose of 60 mg, (c): 12 h after taking loxoprofen at a dose of 60 mg (n = 6 for a and b, n = 5 for c; *P < 0.05 compared with the control; †P < 0.05 compared with the aspirin only group; These values represent the mean ± SEM.)
