Pharmacotherapy for BPH (Benign Prostatic Hyperplasia)
Mechanisms of Obstruction and Rationale for Pharmacotherapy
Current pharmacotherapy for Benign Prostatic Hyperplasia (BPH) is based on agents that relax the smooth muscles of prostatic urethra and stroma and those that deprive acinar cells of androgen.
Various agents have been tried in the treatment of BPH (Table). They may be broadly grouped into those affecting the dynamic component of urethral obstruction, namely the smooth muscle and prostatic stroma, and those affecting the glandular elements by androgen deprivation. The mechanism of action of many agents claimed to be useful in Benign Prostatic Hyperplasia is not clearly understood.
