How Terazosin works
Terazosin is an alpha-1 blocker.
It primarily functions by blocking the action of adrenaline on alpha-1 receptors located on muscle cells in the prostate, bladder neck, and blood vessels. By preventing adrenaline from triggering these receptors and causing muscles to contract, Terazosin allows the muscles to relax.
As a result, it reduces the symptoms of an enlarged prostate by relaxing the muscles in the prostate and bladder neck, thereby improving urine flow.
