Under conditions where vesicular 5-HT accumulation was inhibited by Tbz, citalopram was similarly effective (EC 50 = 94.5 nM; 46.0–194.3 nM; 95% C.I.; log IC 50 not different from Ctrl, P = 0.58, F = 0.32, extra sum-of-squares F test), although a clear trend toward weaker maximal effect was observed (fit bottom = 26.7%; 9.7–43.6%; 95% C.I.; not different from Crtl, P = 0.10, F = 2.71, extra sum-of-squares F test).
