Based on literature data, feasibility of combined therapy with Serenoa repens extracts (including Permixon) and α1-adrenoblocators in patients with LUTS/BPH based on the pathogenesis of these drugs and clinical results was analyzed.
The composition and biological activity of various SRE is influenced by the extraction method, as well as the production technology used by the manufacturer, which can lead to different results of experimental and clinical studies. The mechanism of action of SRE, including hexane extract Permixon, is multicomponent, which combines an antiandrogenic effect, influence on neurogenic regulation of urinary tract function (α-adrenoreceptors, M-holinoreceptors, vanilloid receptors), anti-inflammatory and anti-edematous actions. At the same time, the effect of these preparations is not limited to the influence on the prostate gland, but can directly affect the bladder, helping to reduce functional disorders. A wider range of mechanisms of action and a possible direct effect of SRE on the bladder provides the same clinical effect as other traditionally used drugs (α-blockers, 5α-reductase inhibitors) with a significantly lower frequency of side effects of therapy. A number of publications demonstrate the feasibility of combined therapy with α1-adrenoblockers and SRE in patients with LUTS/BPH, especially with a high degree of urination dysfunction. Futher investigations are needed.
The role of Serenoa repens extracts in the combination therapy of LUTS/BPH is still under discussion. Serenoa repens extracts monotherapy demonstrates similar effectiveness in patients with LUTS as α1-adrenoblockers and 5α-reductase inhibitors. Recent studies indicate the advantages of combining Serenoa repens extracts with α1-adrenoblockers, especially in patients with moderate or severe symptoms. These advantages are associated with the multicomponent action of Serenoa repens extracts, which complements the blockade of α1-adrenergic receptors with other mechanisms of action (in particular, anti-inflammatory).
The combination of drugs with different mechanisms of action, in particular, Serenoa repens extracts (Permixon) and α1-adrenoblockers has certain pathophysiologically based advantages, which allows to increase the efficiency of therapy. In addition, combination therapy is not associated with an increased rate of side effects.
