Abstract:This study investigates the interactions of sibutramine, a hypophagic drug non‐selective inhibitor of norepinephrine (NE) and 5‐HT uptake, with the α1‐ARs subtypes of the rat vas deferens (α1A), spleen (α1B) and aorta (α1D) and with human α1‐ARs subtypes expressed in HEK 293 cells. Sibutramine potentiated the contractions induced by NE in the vas deferens, consistent with an indirect sympathomimetic action. In the rat spleen, sibutramine (up to 100 μM) was unable to affect the contractions induced by NE, sugge… Show more
