    Abstract

    Elevated cholesterol levels, especially low lipoprotein cholesterol (LDL-C), leads to atherosclerosis—which may increase the risk of heart attack, stroke, and peripheral artery disease. Statins are common medications that can help lower cholesterol levels. However, myopathy can be a serious side effect that prevents patients from taking statins and significantly decreases overall quality of life. Described herein are dosage forms containing select combinations of natural herbal extracts and phytonutrients having the surprising ability to lower LDL-C levels in amounts comparable to statin drugs without noted side effects such as myopathy.

    Description

    DETAILED DESCRIPTION

    [0019] Described is a selected combination of plant-natural products with the ability to lower cholesterol, LDL-cholesterol, LDL-C/HDL-C, and total cholesterol/HDL-C, while not lowering desirable HDL-cholesterol levels in the subject. The described compositions containing the selected combination are shown herein to unexpectedly lower total and LDL cholesterol levels in a subject substantially better than the sum of the components of the combination. These results establish an improvement over other dietary supplements and—at least with respect to lowering undesirable cholesterol levels—in efficacy comparable to statin drugs, which is significantly more than the individual components of the selected combinations. Further, as described herein, the described formulations should present an attractive alternative to prescription drugs since, unlike statins, they were not seen to lead to side effects such as myopathy.

    [0020] Specifically described are compositions containing select different botanical extracts and phytonutrients with the ability to lower both total and LDL-C cholesterol levels. While not intending to be bound by theory, the following may help explain the surprising and unexpected results described herein. The described composition are found to inhibit proprotein convertase subtilisin/kexin-type 9 (“PCSK9”) and down-regulate the PCSK9 gene. PCSK9 is a secreted serine protease that regulates the post-transcriptional degradation of the LDL receptor to reduce cholesterol uptake. He et al. (2017) infra. PCSK9 binds directly to the epidermal growth factor repeat A (EGF-A) of the LDL receptor and takes part in the process by which LDL receptors are transported from endosomes to the lysosome for degradation. Cameron et al. (2008) infra. LDL receptors are crucial for regulating cholesterol level. LDL receptors transport LDL-cholesterol from blood into the cell so LDL-cholesterol can be degraded. The presence of PCSK9 in blood serum leads to the degradation of LDL receptor thus causing high cholesterol level in blood. The compositions described herein contain ingredients that suppress PCSK9—thus preventing degradation of the LDL receptor, while maintaining healthy cholesterol levels.

    [0021] As previously identified herein, the dosage form comprise at least five phytonutrients selected from the group consisting of phytosterol or phytosterol esters, berberine, lycopene, silymarin, polydatin, chitosan, danshen extract, Dioscorea nipponica Makia extract, golden kiwi root extract, olive extract, Scutellaria baicalensis extract, white mulberry extract, quercetin, Phaleria macrocarpa fruit extract, pinostrobin, and resveratrol. Preferably, the at least five phytonutrients include at least one of phytosterol, berberine, lycopene, silymarin, and polydatin.

    [0022] Phytosterol and/or phytosterol esters (sometimes called plant sterol and stanol esters) are readily commercially available. Methods of using the dosage forms described herein typically administer to the subject (on a daily basis) from about (plus or minus 5%) 200 mg to about 9,000 mg of phytosterol and/or phytosterol esters. Preferred daily dosages are between 1 and 2 grams. The administration of phytosterol and/or phytosterol esters (in amounts of 1.3 to 1.5 g daily) have been described as reducing LDL-cholesterol in subjects, but only in amounts of about 10.2%. See, e.g., Reaver et al. Nutrients (2019), 1, 2108; and Acuff et al. Lipids in Health and Disease (2007), 6:11.

    [0023] Berberine is readily commercially available. Methods of using the dosage forms described herein typically administer to the subject (on a daily basis) from about (plus or minus 5%) 200 mg to about 1,500 mg of berberine. Preferred daily dosages are between 500 to 900 mg. The administration of berberine (in amounts of 1 g daily) have been described as reducing total cholesterol and LDL-cholesterol in subjects, but only in amounts of about 11.6% and 16.4% respectively. See, e.g., Derosa et al. Expert Opin. Biol. Ther. (2013), 13, 475-482. See, also, Galletti et al. Lipids in Health and Disease, (2019) 2, 66; and Sola et al. PLOS one, (2014) 9, e101978.

Methods of using the dosage forms described herein typically administer to the subject (on a daily basis) from about (plus or minus 5%) 4 mg to about 500 mg of lycopene. Preferred daily dosages are between 100 to 250 mg. The administration of lycopene (in amounts of 22 mg daily) have been described as reducing LDL-cholesterol in subjects, but only in amounts of about 3.7 mg/dl. See, e.g., Nishimura et al. Nutrients (2019) 11, nu11051177. See, also, Misra et al. J. Obstet. Gynaecol. Res. (2006) 32, 299-304 (for a composition containing 4 mg lycopene, together with vitamin A, vitamin E, zinc sulfate monohydrate, and monohydrated selenium dioxide, which reportedly lowered both total cholesterol and LDL-cholesterol in subjects).

    [0025] Silymarin is readily commercially available. Methods of using the dosage forms described herein typically administer to the subject (on a daily basis) from about (plus or minus 5%) 20 mg to about 1,000 mg of silymarin. Preferred daily dosages are between 250 to 750 mg. Silymarin is the extract of Silybum marianum, or milk thistle, and its major active compound is silybin. The administration of silymarin (in amounts of 600 mg daily) have been described as reducing total cholesterol and LDL-cholesterol in subjects, but only in amounts of about 27 mg/dl and 17 mg/dl respectively. See, e.g., Huseini et al. Phytotherapy Research (2006) 20, 1036-1039.

    [0026] Polydatin is readily commercially available. Methods of using the dosage forms described herein typically administer to the subject (on a daily basis) from about (plus or minus 5%) 10 mg to about 1,000 mg of polydatin. Preferred daily dosages are between 250 to 750 mg.

Preferred daily dosages are between 250 to 1,000 mg.

    [0033] White Mulberry extract is readily commercially available. Methods of using the dosage forms described herein typically administer to the subject (on a daily basis) from about (plus or minus 5%) 20 mg to about 1,000 mg of white mulberry extract. Preferred daily dosages are between 250 to 750 mg.

    [0034] Quercetin is readily commercially available. Methods of using the dosage forms described herein typically administer to the subject (on a daily basis) from about (plus or minus 5%) 50 mg to about 1,200 mg of quercetin. Preferred daily dosages are between 250 to 750 mg.

    [0035] Phaleria macrocarpa fruit extract is readily commercially available. Methods of using the dosage forms described herein typically administer to the subject (on a daily basis) from about (plus or minus 5%) 20 mg to about 2,000 mg of the extract. Preferred daily dosages are between 250 to 1,000 mg.

    [0036] Pinostrobin is readily commercially available. Methods of using the dosage forms described herein typically administer to the subject (on a daily basis) from about (plus or minus 5%) 20 mg to about 1,000 mg of pinostrobin. Preferred daily dosages are between 250 to 750 mg.

    [0037] Resveratrol is readily commercially available. Methods of using the dosage forms described herein typically administer to the subject (on a daily basis) from about (plus or minus 5%) 10 mg to about 1,000 mg of resveratrol. Preferred daily dosages are between 250 to 750 mg. The administration of resveratrol (in amounts of 250 mg daily) have been described as reducing total cholesterol and LDL-cholesterol in subjects, but only in amounts of about 29 mg/dl and 19.7 mg/dl respectively. See, e.g., Batista-Jorge et al. Life Science (2020) 256, 117962.

    [0038] In certain embodiments, the methods are particularly useful in treating patients with, for example, high levels of C-reactive protein (“CRP”), since the described compositions do not appear to significantly raise HDL cholesterol in the subject, which has been identified as risky for them. See, e.g., R. Dullaart “Increased Coronary Heart Disease Risk Determined by High High-Density Lipoprotein Cholesterol and C-Reactive Protein: Modulation by Variation in the CETP Gene” Arteriosclerosis, Thrombosis, and Vascular Biology, 2010; 30:1502-1503. Typically, levels of C-reactive protein (CRP) greater than 10 mg/L are considered as a “high level.” Thus, the methods described herein may be particularly useful, when the subject being administered the dosage form(s) has relatively high levels of HDL cholesterol and C-reactive protein (CRP) as may be determined by standard blood testing in comparison to a healthy subject.

    [0039] Once being apprised of the instant disclosure, a person of ordinary skill in the art will be readily able to make or prepare the dosage forms using Galenical techniques. Preferably, a finished product delivery forms is selected from the group consisting of a softgel, capsule, tablet, gel, powder, gummy, liquid, effervescent, bar, topical patch, serum, lotion, and cream.

    [0040] Furthermore, the described dosage forms and methods can be used in combination with other cholesterol-lowering therapies, such as the administration of statins.

    [0041] The invention is further described with the aid of the following illustrative Examples.

    Example I

    [0042] More than 112 dosage forms containing 570 mg phytosterol, 440 mg berberine, 52.5 mg lycopene, 240 mg silymarin and 40.5 mg polydatin were made.

    Example II

    [0043] A pilot study was conducted with four people. Study subjects were instructed to fast for 12 hours before taking blood measurements occurring at time 0 and 4 weeks after supplementation with the formula of Example I once a day before their largest meal of the day.

    [0044] Triglyceride, total cholesterol, and HDL-cholesterol were measured using Cardiochek Home Use Analyzer from pts Diagnostics of Whitestown, Ind., US. LDL-cholesterol was calculated using the Friedewald Equation.

    [0045] Participants were given 4 week servings of Composition of Example I and, after their blood test at time 0, were instructed to take the supplement 15 minutes before their biggest meal daily and for 28 consecutive days thereafter. Participants were instructed to maintain their normal diet and physical activities. A final blood test was conducted on the 31st 29th day after daily consumption of the composition of Example I.

    [0046] Results: After 4 weeks of supplementation with the composition of Example I, there was a significant decrease in total cholesterol (−87.38 mg/dL (−40%), p<0.05) and LDL-cholesterol (−75.15 mg/dL (−54%), p<0.05). There was also a decrease in triglyceride level (−48.63 mg/dL), but the result was not statically significant. There was a decrease in LDL-C/HDL-C (−1.48, p<0.05) and total cholesterol/HDL-C (−1.91, p<0.05). HDL-C did not see any significant change after 4 weeks of supplementation.

    [0047] Daily consumption of the composition of Example I yielded a drastic decrease in total cholesterol and LDL-cholesterol levels in comparison to other cholesterol-lowering supplements containing plant phytonutrients and other vitamins/minerals without altering HDL-cholesterol levels. Surprisingly, Composition of Example I reduced total and LDL cholesterol in a period of four weeks—which is dramatically shorter than the 8-24 weeks often required to see an effect in other cholesterol lowering supplements. See, Galletti et al. (2019); Sola et al. (2014); Derosa et al. (2013); Reaver et al. (2019); Acuff et al (2007); Nishimura et al. (2019); Misra et al. (2006); Huseini et al. (2006); Batista-Jorge et al. (2020); and Sprecher et al. (2002).

    [0048] Not only did the composition of Example I have astonishing results compared against other cholesterol lowering dietary supplements, this study found that the cholesterol-lowering ability of the composition of Example I showed comparable results to statin pharmaceuticals.

    [0049] Table 1 shows the reduction of serum LDL cholesterol levels (mg/dL) according to daily oral doses of different statin drugs. Law et al. (2003) infra screened 165 different clinical studies on different statins with various dosages. These studies lasted typically a few weeks. The results of these studies were compared against the composition of Example I. Only rosuvastatin showed a greater cholesterol-lowering effect at 20 mg or above than the composition of Example I.

    TABLE-US-00001 TABLE 1 Reduction of LDL-C levels (mg/dL) of different statins oral dosage vs Composition of Example I. Rreduction in LDL-C levels (mg/dL) 5 mg 10 mg 20 mg 40 mg 80 mg Atorvastatin 58.3917 69.2193 80.0469 91.2612 102.0888 Fluvastatin 17.7882 28.6158 39.4434 50.271 61.0986 Lovastatin NA 39.4434 54.138 68.4459 83.1405 Pravastatin 28.2291 36.7365 45.2439 53.3646 61.872 Rosuvastatin 71.1528 80.4336 89.7144 98.9952 108.276 Simvastatin 41.7636 50.6577 59.5518 68.8326 77.7267 Formula A 75.15

    [0050] Table 2 also shows that the composition of Example I provides LDL-cholesterol reduction results comparable to other statins used at clinically relevant dosages. With a 54% lowering of LDL-C levels, the composition of Example I outperformed all statins besides rosuvastatin (80 mg) and atorvastatin (20 mg and above). Fan et al. (2020) infra. With a price of about $59/month, the composition of Example I can be much less expensive than branded statin drugs which, depending on dosage, range anywhere from $44-US $508/month.

    [0051] In conclusion, a formula that contains the ingredients as described herein (e.g., the composition of Example I) can perform better than other cholesterol lowering supplements. The described dosage forms achieve similar or even better results than most statins medications, but were not seen to lead to side effects such as myopathy.
