简要总结
The aim of the study is to uses Prosta-OK® Neo that contains herb extracts including lycopene, phellinus linteus, pomegranate, pumpkin seed, selenium and zinc that have been demonstrated with functions of inhibiting 5-alpha reductase, antioxidant, anti-inflammation and regulating the synthesis of nitric oxide to explore whether Prosta-OK® can help reduce symptoms and elevate the quality of life in patients with mild to severe non-neurogenic male lower urinary tract symptoms receiving Tamsulosin therapy.
详细描述
Lower urinary tract symptoms (LUTS) are kind of uncomfortable subjective feelings reported from patients and are divided into three groups, storage, voiding, and postmicturition symptoms. Many epidemiological studies have pointed out that the prevalence of LUTS among individuals aged at least 40 years in the United States, the United Kingdom, Sweden, China, Taiwan, and South Korea is up to 60%. LUTS may cause mental health disorders such as anxiety and depression and affect lifestyle that leads to a negative impact on the quality of life. In recent years, there have been numerous academic or clinical studies that assess the improvement of plant and herb extracts in LUTS.
Prosta-OK® Neo is mainly comprised of herb extracts, including lycopene, phellinus linteus, pomegranate, pumpkin seed, selenium and zinc that have been demonstrated with functions of inhibiting 5-alpha reductase, antioxidant, anti-inflammation and regulating the synthesis of nitric oxide.
The aim of the study is to explore whether take Prosta-OK® 2 tablets for 85 days compared with placebo group can help reduce symptoms and elevate the quality of life in patients with mild to severe non-neurogenic male LUTS receiving Tamsulosin therapy.
