Receptor adrenérgico alfa 1A – Wikipédia, a enciclopédia livre

O receptor adrenérgico alfa 1A (adrenorreceptor α1A). também conhecido como ADRA1A, é um receptor adrenérgico alfa 1 e também denota o gene humano que o codifica.[1] É encontrado no trato urinário e na próstata.[2]

A tansulosina é um fármaco antagonista seletivo desse receptor, sendo utilizado para o tratamento de hiperplasia benigna de próstata. Diminui a obstrução do fluxo urinário (melhorando os sintomas obstrutivos) através do relaxamento da musculatura lisa na próstata e na uretra.[2]
