The alpha-1 adrenoceptors are involved in smooth muscle contraction. This is achieved by the receptor-ligand complex coupling with the G protein alpha-q/11 subtype, which results in increased intracellular calcium and thus muscle contraction. There are 3 subtypes of the alpha-1 adrenoceptor; 1a (Hirasawa A et al, 1993), 1b (Ramarao CS et al, 1992) and 1d (Esbenshade TA et al, 1995).
