PROSTATE FUNCTION SUPPORT FORMULA

Description

RELATED APPLICATIONS

This is a continuation application of U.S. patent application Ser. No. 16/867,386, filed May 5, 2020; which is a divisional application that claims priority to U.S. patent application Ser. No. 15/829,797 filed on Dec. 1, 2017; the contents of the foregoing of which are herein incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

The prostate is a gland that is part of the male reproductive system surrounding the urethra at the neck of the bladder. The main function of the prostate is to make a thin fluid (semen) that lubricates the urethra and transports sperm. As men age, the prostate loses its original structure and function which may lead to urinary problems. Common prostate conditions include prostate cancer which ranks second most common cancer in men. One in seven men will be diagnosed with prostate cancer during his lifetime and is the third leading cause of cancer death in men in the USA (American Cancer Soc. 2017). Symptoms of prostate cancer include difficulty urinating, blood in semen, pelvic and bone pain and erectile dysfunction. Treatment includes radiation therapy, hormone therapy, surgery, chemotherapy, and cryosurgery.

Benign Prostatic Hypertrophy (BPH)—Enlarged Prostate is another common prostate condition in men, with a prevalence of 50%-60% amongst men 60 years or older and 90% for men 70 years or older (Roehrborn, C. G. “Benign Prostatic Hyperplasia: An Overview”, Reviews in Urology 7, Suppl. 9 (2005) S3-S14). Approximately 14 million men in the United States have symptoms of BPH. Men with symptomatic BPH have a 23% lifetime risk of developing acute urinary retention (AUR) if left untreated (Rosenberg, M. T., et al, “STEP. Simplified Treatment of the Enlarged Prostate”, Int. J. Clin. Pract. (2010), 64(4):488-496). Symptoms of BPH include urinary frequency, nocturia, difficulty urinating, and dribbling. Treatment includes alpha blockers, 5-alpha reductase inhibitors, tadalifil, and surgery.

Yet another prostate condition is Prostatitis; the most common urinary tract problem for men younger than age 50 and the third most common urinary tract problem for men older than age 50. Symptoms of prostatitis include painful or difficult urination and pain in the groin, pelvic area or genitals. Treatment includes antibiotics, alpha blockers, and anti-inflammatory agents.

A need exists for safe and effective supplements to treat prostate conditions.

The present invention contains Saw Palmetto, a Tier 2 supplement containing fatty acids and beta-sitosterols, commonly used to help men with prostate or urinary symptoms. Saw Palmetto has been shown in vivo (rat) to reduce the weight and inhibit growth of prostate (Talpur, N. et al “Comparison of Saw Palmetto, extract and whole berry, and cernitin on prostate growth in rats”, Mol. Cell. Biochem. (2003) 250(1-2):21-26). Saw Palmetto is clinically shown to be comparable or more effective than pharmaceutical drugs for pain and urinary symptoms associated with prostatitis and BPH (Cai, T. et al, Int. J. Antimicrob. Agents (2009) 33(6):549-553; Pais, P. et al, Adv. Ther. (2010) 27(8):555-563; Bondarenko, B. et al, (2003) Phytomedicine). Saw Palmetto may help reduce the pressure that the prostate exerts on the urethra by shrinking the lining of the prostate. Saw Palmetto may reduce cancer cell proliferation and inflammation (Goldmann, W. H. et al, Cell Biol. Int (2001) 25(11):1117-1122; Yang, Y. et al, Intl. Jour. Onc. (2007) 31(3):593-600). Additional clinical studies on Saw Palmettol have shown a statistically significant improvement in urinary symptoms in men with LUTS (Lower urinary tract symptoms), a group of clinical symptoms involving the bladder, urinary sphincter, urethra, and, prostate (Gerber, G. S. et al, Urology (2001) 58960-4, 964-965); progress in CPSI (Chronic Prostitis Symptom Index) scores (Kraychick, S. G. et al, 27^th Annual Euro. Assoc. of Urology Cong. Feb. 24-28, 2012, Paris FR), and others (Carraro, J. C. et al, Prostate (1996) 28(4):231-240; Sinescu, I. et al, Urol. Intl. (2011) 86:284-289).

Beta-sitosterols have been shown clinically to decrease levels of DHT (hormone linked to BPH) and significantly improve urinary flow (Berges, R. R. et al, (Lancet (1995) 345:1529-1532; Klipper, K. F. et al, BR J. Urol. (1997) 80(3):427-432). Data comparing men treated with beta-sitosterol to those receiving placebo indicate a significant decrease in symptom scores in the beta-sitosterol group after three and six months of treatment. In a follow-up study, these improvements were maintained for an additional 18 months of observation.

Stinging Nettle is an herb commonly used to treat urinary problems associated with BPH and urinary tract infections (UTI). Stinging Nettle is clinically shown to relieve difficulty in urinating and urge to urinate caused by BPH (Ghorbanibirgani, A. et al, Iran. Red Cres. Med. J. (2013) 15(1):9-10; Pavone, C. D. et al, Yrologia (2010) 77(1):43-51; Safarinejad, M. R. et al, J. Her. Pharmacother. (2005) 5(4):1-11). In vitro, Stinging Nettle is seen to interfere with SHGB and prevent it from combining with androgens (Nahata, A. et al, Andrologia (2012) 44:396-409). Stinging Nettle acts a 5-α-reductase inhibitor, preventing the conversion of testosterone to Dihydrotestosterone (DHT) (Lopatkin, N. et al, World J. Urol. 2005). The German Commission E approves the use of nettle leaf as supportive therapy in patients with LUTS (combined with immune and antimicrobial therapy) and to prevent and treat formation of urinary gravel. Stinging Nettle leads to significant reduction in IPSS (International Prostate Symptoms Score), serum PSA (prostate specific antigen) and prostate size in a prospective, randomized double blind, placebo controlled cross over clinical trial of 558 men with BPH (Safarinejad, M. R. et al, J. Her. Pharmacother. (2005) 5(4):1-11). In a similar trial of 100 men with BPH, the treatment group had better effects in relieving clinical symptoms in BPH patients compared to placebo (Ghorbanibirgani, A. et al, Iran. Red Cres. Med. J. (2013) 15(1):9-10). In one embodiment the Stinging Nettle is used as a herb powder.

Combination therapy clinical studies of Saw Palmetto with Stinging Nettle or Quercetin reduced the symptoms in 85% of LUTS secondary to BPH patients (Pavone, C. D. et al, Yrologia (2010) 77(1):43-51), showed IPSS improvement (Bondarenko, B. et al, (2003) Phytomedicine), was superior to placebo (Lopatkin, N. et al, World J. Urol. 2005), and relieved symptoms of prostatitis (Cai, T. et al, Intl. J. Antimicrob. Agents (2009) 33(6):549-553).

Quercetin (CAS Reg. No. 117-39-5), named as 2-(3,4-dihydroxyphenyl)-3,5,7-trihydroxy-4H-chromen-4-one, is a plant polyphenol from the flavonoid group, found in many fruits, vegetables, leaves, and grains. Quercetin is a Tier 1 supplement and naturally occurring flavonoid recognized as a potent antioxidant, anti-inflammatory and gives relief of symptoms associated with prostatitis. Quercetin promoted prostate cancer cells apoptosis and caspase activation in vitro (Kim, Y. H. et al, J. Cell. Biochem. (2007) 100(4):998-1009; Lee, D. H. et al, Biochem. Pharmacol. (2008) 75(12):2345-2355; Xing, N. et al, Carcinogenesis (2001) 22:409-414; Wang, G. et al, Oncol. Rep. (2013) 30:357-363). Quercetin is effective in vivo in combination with finasteride to reduce prostate weight and anti-tumor activity (Ma, Z. et al, J. Endocrinol. (2004) 181(3):493-507; Ferry, D. R. et al, Clin. Cancer Res. (1996) 2(4):659-668). Quercetin is clinically shown to provide symptomatic improvement in CP/CPPS and shown to enhance the efficacy of antibiotic to treat CP when used in combination with other natural ingredients; saw palmetto and stinging nettle (Cai, T. et al, Intl. J. Antimicrob. Agents (2009) 33(6):549-553). Quercetin is a recommended treatment through the UPOINT System for Prostatitis Treatment used by medical professionals (Shoskes, D. A. et al, Urology (2010) 75(6); Shoskes, D. A. et al, Urology (1999) 54(6):960-963) demonstrating decrease in IPSS in a randomized, double-blind, placebo controlled clinical trial. Quercetin has an effect on human prostate tumor in vivo xenografts in mice and inhibits prostate cancer cell proliferation in vitro (Yang, F. et al, Oncology Reports (2016) 35(3):1602-1610).

Pygeum Africanum is a Tier 2 herb used to promote prostate and bladder health, BPH, and nocturia (also known as nycturia, the need to urinate at night) reduction. The major active components of Pygeum Africanum are fat-soluble sterols (phytosterols) and fatty acids that can inhibit the production of DHT (dihydrotestosterone), pro-inflammatory prostaglandins in the prostate (Andro, M. C. et al, Curr. Ther. Res. (1995) 56:796-817; Monograph. “Pygeum africanum”, Alternative Medicine Review. (2002) V7(1)), and triterpenes and ferulic acid nesters to block the accumulation of cholesterol in the prostate. Pygeum Africanum is shown in vitro and in vivo to modulate bladder contractility, inhibit cancer cell proliferation and viability, promote cell apoptosis, and suppress production of prostaglandins (Levin, R. M. et al, J. Urol. (1996) 156:2084-2088; Santa Maria, M. A., et al, Arch. Esp. Urol. (2003) 56(4):369-378; Boulbes, D. et al, BJU Int. (2006) 98(5):1106-1113; Quiles, M. T. et al, Prostate (2010) 70(10):1044-1053; Papaioannou, M. et al, Invest. New Drugs (2010) 28(6):729-743). Pygeum Africanum is clinically shown to improve urinary flow, reduce nocturia, and improve prostate symptoms, urinary parameters, and sexual function in men with BPH or prostatitis (Andro, M. C. et al, Curr. Ther. Res. (1995) 56:796-817; Carani, C. et al, Arch. Ital. Urol. Nefrol. Androl. (1991) 63(3)341-345; Chatelain, C. et al, Urology (1999) 54(3):473-478; Barlet, A. et al, Wein Klin. Wochesschr. (1990) 102:667-673; Breza, J. et al, Curr. Med. Res. Opin. (1998) 14(3):127-139).

Green Tea Extract is a Tier 2 supplement with antioxidant qualities to provide support for prostate health, normal prostate size, and anti-cancer protective effect. Green Tea Extract is shown to regulate DHT production and hormones that influence prostate volume. Catechins (polyphenol compounds) in green tea shown to have anti-inflammatory qualities, reduce infection, enhance the immune system, and regulate the production and activities of hormones (Alschuler, L. et al, Am. J. Natur. Med. (1996) 5:28-31; Graham, H. N. et al, Prev. Med. (1992) 21:334-350). In vitro, in vivo and clinical studies identified EGCG (green tea catechin) to be a modulator of molecular pathways to prostate carcinogenesis (Nihal, A. et al, Nutr. Rev. (1999) 57:78-83; Ahmad, N. et al J. Natl. Cancer Inst. (1997) 89:1881-1886). In vitro EGCG acts as an anti-androgen antagonist, suppresses prostate cancer cell proliferation and production of prostate-specific antigen (PSA), reduces tumor size and delays development of prostate tumors in TRAMP mice (Adhami, V. M. et al, Clin. Cancer Res. (2009) 15(6):1947-1953; Gupta, S. et al, Proc. Natl. Acad. Sci. USA (2001) 98(18):10350-10355; Kim. S. J. et al, Cancer Prev. Res. (2014) 7(4):435-444). Clinically shown in randomized trials to reduce overall rate of progression of prostate cancer in men with HGPIN (high-grade prostatic intraepithelial neoplasia), an abnormality of prostatic glands and believed to precede the development of prostate adenocarcinoma, the most common form of prostate cancer (Kumar, N. B. et al, Cancer Prev. Res. (Phila) (2015) 8(10):879-887; Bettuzzi, S. et al, Cancer Res. (2006) 66(2):1234-1240; Brausi, M. et al, Eur. Urol. (2008) 54(2):472-473). Other clinical trials with great tea and/or its components shown benefits of decreased PSA levels, and other biomarkers correlated with prostate cancer (Henning, S. M. et al, Prostate (2015) 75(5):550-559; McLarty, J. et al, Cancer Prev. Res. (2009) June 19; Nguyen, M. et al, Cancer Prev. Res. (Phila) (2012) 5(2):290-298).

Lycopene is a Carotenoid produced by plants. Lycopene enhances antioxidant response to support prostate health and is generally recognized as safe (GRAS). Epidemiological/Clinical studies link increased lycopene consumption with decreased prostate cancer risk, decreasing serum PSA levels, suppression of tumor growth and supporting urinary function (Obermuller-Jevic, U. C. et al, J. Nutr. 133(11):3356-3360; Ford, N. A. et al, Nutr. Cancer (2011) 63(2):256-263; Yang, C. M. et al, J. Nutr. Biochem. (2012) 23(1):8-17; Zhang, X. et al, Chin. Med. J. (2010) 123(16):2231-2236; Mariani, S. et al, Int. J. Mol. Sci. (2014) 15(1):143301440; Qiu, X. et al, Cancer Prev. Res. (Phila) (20-13) 6(5):419-427; Tang, Y. et al, Neoplasia (2011) 13(2):108-119; Gann, P. H. et al, Cancer Res. (1999) 59(6):1225-1230). Animal studies show antitumorigenic effect (Yang, C. M. et al, Mol. Nutr. Food Res. (2011) 55(4):606-612; Yang, C. M. et al, J. Nutr. Biochem. (2012) 23(9):1155-1162). Lycopene is shown in vitro and in vivo to enhance the antioxidant response of prostate cells, inhibit proliferation, demonstrate chemopreventive effect induce apoptosis and decrease the metastatic capacity of prostate cancer cells and may affect insulin-like growth factor (IGF) intracellular pathway in prostate cancer cells (Konijeti, R. et al, Prostate (2010) 70(14):1547-1554; Kim, H J. S. et al, Nutr. Cancer (2003) 47(1):40-47). Clinical trials with lycopene showed reduction of PSA levels (Kucuk, O. et al, Exp. Biol. Med. (2202) 227(10):881-885; Schwarz, S. 1391(1):49-53; Mohanty, N. K. et al, Urol. Oncol. (2005) 23(6):383-385; Ansari, M. S. et al, BJU Intl. (2003) 92(4):375-378).

Vitamin E, an essential vitamin, and Selenium, an essential mineral, have antioxidative properties and are widely used to prevent damage to the cells, tumor suppression in prostate cancer and provide immune support. Vitamin E and selenium have been shown in vitro and in vivo to reduce risk of prostate cancer, suppress tumor progression and cell apoptosis (Pinto, J. T. et al, Int. J. Cancer (2007) 120(7):1410-1417; Zhang, Y. et al, Proc. Natl. Acad. Sci. USA (2002) 99(11):7408-7413; Limpens, J. et al, J. Nutr. (2006) 136:1287-1293; Malafa, M. et al, Intl. J. of Cancer (2006) 118(10):2441-2447). Selenium has shown in vitro to decrease the activity of the androgen receptor leading to apoptosis and growth inhibition on prostate cancer cells, increase levels of p53 (tumor suppression) and regulate oxidative and the immune system (Kong et al, Biomaterials (2011) 32(27):6515-6522; Sarveswaran, S. et al, Int. J. Oncol. (2010) 36(6):1419-1428). Higher blood selenium concentrations have been clinically associated with decreased prostate cancer (EPIC and Physicians' health study) and decrease PSA levels (Clark, L. C. et al, British J. of Urol. 1998) 81:730-734; Allen, N. E. et al, Am. J. Clin. Nutr. (2008) 88(6):1567-1575; Li, H. et al, J. Natl. Cancer Inst. (2004) 96(9):696-703; Meyer, H. A. et al, Cancer Epidemiol. Bioimarkers Prev. (2009) 18(9):2386-2390).

Vitamin B-6 is required for proper prostate function cell repair and immune health, and the proper manufacture and metabolism of hormones necessary for prostate health.

Zinc is a Tier 3 supplement for prostatitis, prostate cancer and BPH. Zinc induces apoptosis and antiproliferative effects on prostate cancer and BPH cells in vitro (Costello, L. C. et al, Open Urol. Nephrol. J. (2008) 1; Franklin, R. B. et al, Arch. Biochem. Biophys. (2007) 463(2):211-217. Zinc plays a role in testosterone, sperm formation and motility, and DNA damage repair (Netter, A. et al, Arch. Androl. (1981) 7(1):69-73). Clinical experience associates an inverse relationship between zinc intake and risk of prostate issues (Medarova, Z. et al, Am. J. Cancer Res. (2014) 4(4):385-393; Costello, L. C. et al, Mol. Cancer. (2006) 5:17; Mahmoud, A. M. et al, PLoS ONE (2016) 11.11 e0165956 PMC).

“Zinc gluconate” is the zinc salt of gluconic acid. It is an ionic compound consisting of two anions of gluconate for each zinc (II) cation. Zinc gluconate is available from a number of commercial sources.

“Selenium as an amino acid chelate” is an enhanced form of selenium, a vital trace element nutrient with multiple roles in the growth and functioning of living cells in higher animals and humans. Inorganic salt forms of selenium such as sodium selenite and sodium selenite when complexed or incorporated with amino acids, such as aspartic acid and methionine, form selenium-amino acid chelates with enhanced absorption properties.

“Copper gluconate” is the copper salt of gluconic acid. It is soluble in water and insoluble in ethanol. Copper gluconate is available from a number of commercial sources.
