title: [Pharmacological combinations in the treatment of benign prostatic hypertrophy].
abstract: In the development of the obstructive symptomatology of benign prostatic hypertrophy (BPH), two components may be identified, mechanical and dynamic. In the mechanical component, the interaction of a stromal and a epithelial compartment determines prostatic mass growth. The dynamic component involves smooth muscle tone in the prostate and urethra. The consideration that prostatic disease is not only epithelial in origin, but also stromal, leads to the association of an antiandrogen (which acts on the epithelial component) and an antiestrogen (active on the stromal component) in the medical therapy of BPH. In 1985 we carried out a randomized study on 256 BPH patients treated with Cyproterone acetate (CPA) plus Tamoxifen (TAM). Recently, we performed a multicenter double blind study on BPH patients treated with the association CPA plus Serenoa Repens. A statistically significant difference in prostate volume reduction between the groups treated with the combinations and those with the monotherapies was observed. The development of new compounds, such as 5 alpha reductase and aromatase inhibitors, consents to introduce a combination therapy with less side effects. A second pharmacological association may be obtained with drugs acting on the mechanical and others acting on the dynamic (alpha blockers) component of BPH. This combination may associate the early symptomatic effect of alpha blockers with the long term results of a 5 alpha reductase inhibitor, antiestrogen or aromatase inhibitor.
