FRIDAY, Oct. 7 (HealthDay News) -- The erectile dysfunction drug

high blood pressure or anxiety.
Eight other drugs have been approved to treat symptoms of BPH:
Proscar (finasteride), Avodart (dutasteride), Jalyn (dutasteride
and tamsulosin), Hytrin (terazosin), Cardura (doxazosin), Flomax
(tamsulosin), Uroxatral (alfuzosin) and Rapaflo (silodosin).
Cialis is produced by Indianapolis-based Eli Lilly and Co.
