Reduction of the serotonin 5-HT1B and 5-HT2A receptor-mediated contraction of human pulmonary artery by the combined 5-HT1B receptor antagonist and serotonin transporter inhibitor LY393558.

CONCLUSIONS: LY393558 reduces the 5-HT-induced contraction antagonizing 5-HT1B and 5-HT2A receptors probably due to synergic interaction between SERT inhibition and 5-HT1B receptor antagonism. Thus, it might represent a valuable future option in the pulmonary arterial hypertension therapy.
