Prostate volume in ml by age
A simplified International Index of Erectile Function questionnaire was used to assess effects on erectile function.
1. Introduction
There appears to be no clear relationship between the size of the prostate and the severity of symptoms [1,2]. Drugs with no unwanted side-effects sh; ould be the ideal agents for improving LUTS.
Patients were enrolled at four Hungarian clinical sites. To decrease the known placebo effect in this patient population [5], a day placebo lead-in period preceded the active phase.
World J Urol. Methadone Powder Description No improvement noted in overall or cause-specific survival for men presenting with metastatic prostate cancer over a year period. Cancer ; — Surgical cytoreduction of the primary tumor reduces metastatic progression in a mouse model of prostate cancer.
For minimizing the bias of the single-blinded design, both during the lead-in and the active phase patients received capsules of similar appearance.
Efficacy was primarily determined by changes in AUA symptom score maximum 35 points and maximum urinary flow rate A prosztata titokzata. None of the drug-related adverse events associated with selective α1-blockers were reported.
Prostate volume normal ml.
KEYWORDS α-blockers, benign prostatic hyperplasia, medical therapy, outcome Residual urine volume and prostate size were measured by abdominal ultrasonography. As a safety endpoint orthostasis was determined by measuring blood pressure BP and heart rate HR changes with the patient supine and upright at 30 and s after standing up before, then 0.
Clinical safety, tolerability and adverse-event profile were also recorded. Patients were asked to complete a simplified 5-item International Index of Erectile Function IIEF-5 questionnaire, a brief and reliable selfassessment tool for evaluating the severity of erectile dysfunction [6].

All patients provided signed informed consent before enrolment. The study was performed in accordance with the ethical principles of the declaration of Helsinki and in compliance with the Good Clinical Practice guidelines. The single-blind medication placebo or active drug was manufactured according to standard rules, and were packaged and dispensed to the patients weekly.
The randomization code was generated using the random number generating feature of commercial software, in blocks of four. Prostate volume in ml by age main variables analysed at baseline, and at the fourth end of placebo lead-in and eighth week end of active phase were changes in AUA symptom score, Qmax and IIEF-5 score.

Orthostatic BP and HR measured while supine and standing at 30 and s before, then 0. Reasons for exclusion were: placebo effect withdrawal during the placebo lead-in phaseprotocol violation, patient decision, abnormal laboratory value, lost to follow-up or need for immediate surgery. The patients evaluated had similar demographic and baseline disease characteristics Table 1.
Sexual function was not adversely affected by treatment with GYKI; there were none of the erectile side-effects reported even for the selective α1-blockers e. Any illnesses, signs or symptoms that appeared or worsened during the course of the study i. None of the patients who qualified for enrolment discontinued the treatment because of drug-related adverse events. No orthostatic hypotensive reaction occurred on study medication Table 1.
The three mild adverse events noted during the whole study were classified as unrelated to the study drug.
Clinical trials
The first-line treatment for BPH is pharmacotherapy, aimed primarily at reducing bothersome symptoms and preventing urinary retention, as well as the risk of invasive therapy. Medical treatment includes 5α-reductase inhibitors and α1adrenergic antagonists; the former target the static prostate volume in ml by age by reducing the size of the gland, but are less popular than α1-blockers, which influence the dynamic component and improve the symptoms more quickly, by decreasing the sympathetic tone of the smooth muscle of the prostate, bladder neck and proximal urethra.
There are three distinct native members of the G-protein coupled α1-receptor subfamily, i. In human prostatic stroma mostly α1A receptors mediate the sympathetic tone, while α1D subtypes are present to a lesser degree, although the latter show higher affinity for the endogenous catecholamines.
A novel approach to the treatment of benign prostatic hyperplasia
Because of the different subtype distribution in the urinary tract and cardiovascular tissue, efforts have been made to develop uroselective agents that target predominantly α1A receptors, supposing that subtypeselective antagonists should have fewer haemodynamic side-effects than nonselective drugs.
However, preclinical and clinical studies failed to show a clear benefit in efficacy and safety for subtype selective compounds over subtype nonselective α1antagonists; almost all marketed drugs show a similar side-effect profile [9—11].
Although tamsulosin has less effect on blood pressure and causes less orthostatic hypotension than terazosin or doxazosin, this may be a consequence of its delayed-release formulation [12].

It was suggested by Andersson [13] that the α1-receptors of the lower urinary tract are most probably not unique and α1-receptors outside the prostate may also contribute to the symptoms. Furthermore, although the dominance of α1-receptors in the prostate is unambiguous, human hyperplastic prostate tissue also has abundant α2-receptors [14].
Clinical trials
Several studies report evidence that α2receptor agonists may disturb urinary function, suggesting a role for these receptors [15]. The first adrenergic compound used for the pharmacological treatment of BPH was the nonselective agent phenoxybenzamine. Although it was therapeutically highly effective in reducing both the obstructive and irritative symptoms, the high incidence of adverse events, including orthostasis, reflex tachycardia, stuffy nose and miosis limited its use.
These unwanted effects were attributed to lack of selectivity for α1 over α2 receptors. TABLE 1 Demographic data and disease characteristics at baseline, screening visit 1active phase enrolment visit 4 and after a day oral treatment with placebo or 7. Some reports suggest a role for extraprostatic α1- and prostatic postsynaptic α2-receptors in BPH [16].
Also, α1- and postsynaptic α2-receptor blockers may beneficially modify erectile dysfunction [17].
Introduction
Based on these findings, preclinical experiments at our institute used several combined α1- and postsynaptically selective α2-blockers, among which GYKI was selected for development due to its unique characteristics. In different animal models of BPH, the compound had no influence on cardiovascular function and showed functional uroselectivity; it also increased the copulatory activity of male rats, similarly to yohimbine.
To characterize the clinical efficacy and safety of GYKI in patients with BPH, a placebo-controlled randomized clinical trial was conducted. Despite the short treatment period, its efficacy was very similar to that of marketed drugs administered for longer periods.
We suggest that this is attributed at least partly to its affinity for the postsynaptic α2-receptors and to the significant difference between post- and presynaptic α2 activity.
Very similar results were obtained with the present day treatment with GYKI 15 mg. Although this short clinical trial involved only relatively few patients with BPH, most importantly, none of the well-known sideeffects of the presently marketed drugs dizziness, postural hypotension, asthenia, headache, fatigue, abnormal ejaculation, etc.
We conclude that the combined α1- and postsynaptically selective α2-blocker GYKI significantly improved the AUA symptom scores and Qmax at prostatitis amboss deutsch as effectively as the marketed adrenergic drugs but with none of their orthostatic hypotensive or other side-effects, indicating that GYKI has the potential to become an ideal treatment for BPH.
Longer controlled trials are needed to support this presumption.
