                                                    The aim of our study was to examine the effect of LY393558 on the 5-HT-stimulated vasoconstriction of human pulmonary arteries (hPAs) and to determine the underlying mechanism(s). LY393558 showed the greatest antagonistic effect against the vasoconstriction elicited by 5-HT, 5-CT and α-methyl-5-HT.

                                                    The effect of LY393558, a potent 5-hydroxytryptamine reuptake inhibitor with 5-HT1B/1D receptor antagonist properties, on seizure-induced respiratory arrest evoked by acoustic stimulation was also examined in DBA/1 mice. Acute administration of LY393558 also significantly reduced seizure-induced respiratory arrest in DBA/1 mice.
