En av de två större farmakologiska undergrupperna av adrenerga receptorer som ursprungligen definierades efter den relativa potensen hos olika adrenerga föreningar. Alfareceptorerna beskrevs först som stimulerande receptorer som åstadkommer kontraktion i glatt muskulatur. Noggrannare undersökningar påvisar dock en mer komplex bild som involverar flera undertyper av alfareceptorer och deras roll vid återkopplingsreglering.
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.
