    Harmacologic therapies for bph, and the treatment duration was at least 30 days. buy generic viagra Key data were extracted independently by two investigators. Results: a total of 44 studies of six phytotherapeutic agents (serenoa repens, hypoxis rooperi, secale cereale, pygeum africanum, urtica dioica, curcubita pepo) met inclusion criteria and were reviewed. Many studies did not report results in a method allowing meta-analysis. Serenoa repens, extracted from the saw palmetto, is the most widely used phytotherapeutic agent for bph. cheap viagra online A total of 18 trials involving 2939 men were reviewed. Compared with men receiving placebo, men taking serenoa repens reported greater improvement of urinary tract symptoms and flow measures. Serenoa repens decreased nocturia (weighted mean difference (wmd) = -0. 76 times per evening; 95% ci = -1. 22 to -0. 32; n = 10 studies) and improved peak urine flow (wmd = 1. 93 ml s(-1); 95% ci = 0. buy generic viagra online 72 to 3. which is safer viagra viagra or viagra 14, n = 8 studies). Men treated with serenoa repens rated greater improvement of their urinary tract symptoms versus men taking placebo (risk ratio of improvement = 1. 72; 95% ci = 1. 21 to 2. safest place buy generic viagra 44, n = 8 studies). Improvement in symptoms of bph was comparable to men receiving the finasteride. Hypoxis rooperi (n = 4 studies, 519 men) was also demonstrated to be effective in improving symptom scores and flow measures compared with placebo. recreational use of viagra For the two studies reporting the international prostate symptom score, the wmd was -4. 9 ipss points (95% ci = -6. 3 to -3. 5, n = 2 studies) and the wmd for peak urine flow was 3. buy viagra canada 91 ml s(-1) (95% ci = 0. 91 to 6. 90, n = 4 studies). Secale cereale (n = 4 studies, 444 men) was found to modestly improve overall urological symptoms. Pygeum africanum (n = 17 studies, 900 men) may be a useful treatment option for bph. does viagra 100 mg look like However, review of the literature has found inadequate reporting of outcomes which currently limit the ability to estimate its safety and efficacy. The studies involving urtica dioica and curcubita pepo are limited although these agents may be effective combined with other plant extracts such as serenoa and pygeum. order viagra online Adverse events due to phytotherapies were reported to be generally mild and infrequent. Conclusions: randomized studies of serenoa repens, alone or in combination with other plant extracts, have provided the strongest evidence for efficacy and tolerability in treatment of bph in comparison with other phytotherapies. Serenoa repens appears to be a useful option for improving lower urinary tract symptoms and flow measures. Hypoxis rooperi and secale cereale also appear to improve bph symptoms although the evidence is less strong for these products. Pygeum africanum has been studied extensively but inadequate reporting of outcomes limits the ability to conclusively recommend it. There is no convincing evidence supporting the use of urtica dioica or curcubita pepo alone for treatment of bph. Overall, phytotherapies are less costly, well tolerated and adverse events are generall. cheapest viagra price
