They are similar, but terazosin has a wider spectrum for treating more conditions, but one is a selective alpha antagonist and the other is an alpha receptor antagonist.-
Meaning terazosin α-antagonists are pharmacological agents that act as antagonistsis (a type of receptor ligand or drug that does not provoke a biological response itself upon binding to a receptor, but blocks or dampens agonist-mediated responses) of α adrenergic receptors (α-adrenoceptors)
Terazosin is a selective alpha 1 antagonist used for treatment of symptoms of an enlarged prostate (BPH). It also acts to lower the blood pressure, and is therefore a drug of choice for men with hypertension and prostate enlargement.
It works by blocking the action of adrenaline on smooth muscle of the bladder and the blood vessel walls.
Alfuzosin Specific actions of the α1 receptor mainly involve smooth muscle contraction. It causes vasoconstriction in many blood vessels including those of the skin, gastrointestinal system, kidney (renal artery) and brain.-
Alfuzosin is an α1 receptor antagonist used to treat benign prostatic hyperplasia (BPH). It works by relaxing the muscles in the prostate and bladder neck, making it easier to urinate.
