The two primary drug classes used for BPH are: Alpha-blockers. These drugs relax smooth muscles, especially in the bladder neck and prostate. They include terazosin (Hytrin), doxazosin (Cardura), tamsulosin (Flomax), alfuzosin (Uroxatral), and silodosin (Rapaflo). Alpha-blockers help relieve BPH symptoms, but they do not reduce the size of the prostate.
Barbiturates are in the group of medicines known as central nervous system depressants (CNS). Also known as sedative-hypnotic drugs, barbiturates make people very relaxed, calm, and sleepy. These drugs are sometimes used to help patients relax before surgery. Some may also be used to control seizures (convulsions).
