  rdf:value "Una de las dos principales subdivisiones farmacológicas de los receptores adrenérgicos que fueron originalmente definidas por las potencias relativas de varios compuestos adrenérgicos. Los receptores alfa fueron descritos inicialmente como receptores excitatorios que realizan un estímulo postjuncional en la contracción del músculo liso. Sin embargo, un mayor análisis reveló una imagen más compleja de subtipos de receptores alfa y su participación en la regulación de la retroalimentación."@es, "One of the two major pharmacological subdivisions of adrenergic receptors that were originally defined by the relative potencies of various adrenergic compounds. The alpha receptors were initially described as excitatory receptors that post-junctionally stimulate smooth muscle contraction. However, further analysis has revealed a more complex picture involving several alpha receptor subtypes and their involvement in feedback regulation."@en ;
