Description

Title
Oral composition for the treatment and/or prevention of disorders associated with menopause.
STATE OF THE ART
Menopause means the definitive cessation of menstrual cycles, resulting from the loss of ovarian follicular function, and is retrospectively diagnosed after 12 consecutive months of amenorrhea or absence of the menstrual cycle.
The climacteric is defined as the period that precedes and follows menopause. During this transition phase, the onset of physical and psychological disorders, which depend on the progressive deficiency of hormones (including estrogen) and the involution of the functional activity of the ovaries, is common. Indicatively, the climacteric begins around 40-50 years of age and lasts about 7-10 years. Although not a disease, this physiological phase is characterized by a series of disorders (hot flashes, insomnia, irritability, vaginal dryness, decreased libido), common to many women; we speak, in fact, of climacteric syndrome.
Hot flashes (or flushes) and sweating, secondary to vasomotor instability, affect 75 to 85% of women and usually appear before the interruption of the menstrual cycle. They last on average about 7.5 years, but also more than 10 years. Generally, the intensity and frequency of hot flashes decrease over time. They are the most common reason for which women seek medical attention during the perimenopausal period, especially if symptoms impair the quality of life. Symptoms associated with menopause, both neurovegetative (hot flashes, sweating, headache) and psychoaffective (irritability, anxiety, depression, nervousness, sleep disorders), as well as osteoporosis and increased cardiovascular risk, which are known to manifest themselves in the climacteric, are attributable to the lack of estrogens.
Hormone replacement therapy therefore constitutes an effective therapeutic remedy. However, the administration of estrogen is not without risk, especially in the long term. Risks of estrogen therapy and combined estrogen/progestogen therapy include endometrial cancer, deep vein thrombosis, pulmonary embolism, stroke, breast cancer, cholecystopathy, and urinary stress incontinence. Additionally, estrogen therapy may be contraindicated in women who have had or are at high risk for breast cancer, stroke, coronary heart disease, or thrombosis.
A natural aid against menopause symptoms would seem to come from phytoestrogens. These are compounds of plant origin with a biphenolic structure similar to that of estrogens. This provides them with pseudo- hormonal properties, including the ability to bind estrogen receptors, and are therefore also known as plant estrogens. Although these molecules have been the object of extensive research, their role in the well-being of the human body remains controversial1 ,2 due to the estrogen-like effects that may be a risk for some individuals (for example in women undergoing treatment with tamoxifen, phytoestrogens could antagonize the desired antiestrogenic effect of the drug).
Due to the possible adverse effects of hormonal and phytoestrogen-based therapy, there is an increasing demand for alternative natural treatments (certainly less powerful than hormones but surely free of serious side effects) for the symptoms and pathological processes associated with menopause.
Several studies have shown that the reduction in estrogens that occurs in menopause is associated with an increase in oxidative stress. In addition to being associated with a wide range of diseases (cardiovascular diseases, diabetes, Alzheimer’s disease, etc.), oxidative stress is also involved in the pathogenesis of vasomotor disorders of menopause (hot flashes and night sweats).3
Flavonoids or bioflavonoids represent a large class of phenolic compounds widespread in the plant world. From the numerous studies conducted on this large variety of compounds, it has emerged that flavonoids are able to exert various beneficial actions on the human body. More specifically, among the main biological activities ascribed to flavonoids4 we find: antioxidant and radical scavenger activity; anti-inflammatory activity and protective and strengthening activities against capillaries and microcirculation.
Their potential ability to capture and chelate metals and reactive oxygen species (ROS) depends on the chemical structure and the number and position of the hydroxy groups. This antioxidant action makes flavonoids very useful in all those conditions characterized by strong oxidative stress.
It has also been observed that flavonoids improve the quality of the blood vessel wall and protect against aging processes by reducing the risk of atherosclerosis5.
Plants belonging to the Citrus genus, more commonly known as citrus fruits, are particularly rich in bioflavonoids. Among these, the lemon (deriving from the Citrus lirnon L. plant) is a fruit very rich in important natural compounds, including flavonoids, citric acid, ascorbic acid, minerals, and essential oils. Lemon extract is usually titrated in flavonoids (not belonging to the class of isoflavones).
Ashwagandha (also called Withania somnifera (L.) Dunal) is a plant which has been known for many years for its adaptogenic properties. Over 50 chemical constituents have been identified in the various parts of the Ashwagandha plant; among the major components we find alkaloids (isopelletierins, anaferins, etc.), steroidal lactones (withanolides, withaferins) and saponins.6 The extract is usually titrated in withanolides. Many pharmacological studies were conducted in order to describe the multiple biological activities of the Withania somnifera L. Dunal plant. Ashwagandha helps reduce stress, anxiety, mood swings, cortisol levels and stress-related food cravings.7 Ashwagandha exerts its beneficial effects on anxiety and related disorders thanks to its GABA-mimetic properties.8 The clinical study conducted by Chandrasekhar and collaborators9 showed that Ashwagandha is able to reduce cortisol levels in the blood, thus reducing the levels of stress and depression, and of physiological markers of anxiety. Moreover, by significantly reducing cortisol concentrations, Ashwagandha helps relieve insomnia. Ashwagandha exerts these positive effects on sleep disorders without causing drowsiness during the day or, on the contrary, possessing the excessively stimulating effects that other excellent phytotherapeutic drugs with a tonic action can sometimes have, such as real ginseng. One study has shown that Ashwagandha can reduce the onset of vasomotor symptoms.10
Furthermore, Ashwagandha can be effective in improving both immediate and general memory, as well as improving executive function, attention, and information processing speed.11
The study conducted by Dongre and collaborators12 showed that Ashwagandha is able to improve sexual function in healthy women.
Finally, Ashwagandha also appears to have an anti-aging effect.13 Aging and lifespan of normal and healthy cells are linked to the telomerase shortening mechanism, which limits cells to a fixed number of divisions. Extracts from Ashwagandha root can significantly increase telomerase activity, thereby protecting against telomere loss and potentially delaying aging. A study conducted by Raguraman and collaborators13 showed that the incubation of human FleLa cells with Ashwagandha root extract improved telomerase activity by 45%.
Flowever, to date, none of the pharmacological treatments or natural treatments available on the market has allowed us to observe a particular and valid efficacy in the prevention and/or treatment of disorders associated with menopause.
The need for a new and improved therapeutic treatment that has the advantage of being a highly specific treatment with reduced or even absent side effects, as compared to the classic therapies known for the treatment and/or prevention of disorders associated with menopause, is therefore apparent.
DESCRIPTION OF THE INVENTION An object of the present invention is therefore to provide a natural, innovative, and non-hormonal, effective and safe product for the treatment of menopause symptoms, both of neurovegetative and psychoaffective nature.

CLINICAL STUDY
An observational epidemiological study was conducted on a group of 40 women in pre-menopause or post-menopause phases with classic autonomic and psychoaffective symptoms. The enrollment period was of 2 months and a follow-up check was performed at day 15, day 30 and day 60. The women were treated with the formulation of Example 1 , twice a day for a period of 1 month and then with 1 capsule a day for another month. The purpose of the study was to verify the efficacy of the formulation in improving the well-being of the woman during the study period, by relieving the neurovegetative and psycho-affective symptoms typical of menopause, such as hot flashes, sweating, sleep disorders, mood swings, irritability, headaches, feelings of tiredness/fatigue and decreased libido.
FOLLOW-UP AND OBSERVATIONAL RESULTS
A total of 40 women between the ages of 47 and 60 (average 51.7 ± 3.4 years) were enrolled for the observational study. Of these, 25 women were in a pre-menopause phase and the other 15 were in a post-menopause phase.
A numerical scale from 0 (no symptoms) to 5 (maximum intensity) was used for the evaluation of symptoms.
The 7 most common symptoms associated with menopause were evaluated: hot flashes, sweating, sleep disorders, mood swings, irritability, headaches, tiredness/fatigue.
The results, reported as the average value for each symptom ± the standard deviation, are summarized in Table 1 and graphically represented in Figure 1. Table 1. Effect of the formulation of Example 1 on the classic symptoms of menopause.
Table 2 shows the percentage changes calculated with respect to visit 1. Table 2. Percentage change in symptoms associated with menopause calculated for visit 2 (day 15), visit 3 (day 30) and visit 4 (day 60) compared to the starting value recorded at visit 1.

All treated women reported a reduction in symptoms related to hot flashes, sweating, sleep disorders, mood swings, irritability, headache, and fatigue. An improvement in symptoms was observed already after 15 days of treatment, while after 2 months of treatment the average reduction of all symptoms was of 55.8%. Hot flashes and sweating, the most annoying menopause symptoms, recorded a clear and surprising reduction after 2 months of treatment, equal to 60.8% and 64.2%, respectively.
In addition to the symptoms described above, the efficacy of the treatment in improving the decreased libido was also evaluated in a small group of patients compared to the total number of women enrolled (18 patients). The results are shown in Figure 2, where changes in decreased libido are observed.
After 2 months of treatment with the formulation of Example 1 , an improvement in sexual desire (libido) equal to 28.3% was obtained.
CONCLUSIONS
In general, the results of the observational study showed that the formulation containing a lemon extract (d.e. from Citrus Limon (L.) Osbeck) and an Ashwagandha ( Witania somnifera (L.) Dunal) extract is surprisingly effective in improving symptoms (both of neurovegetative and psychoaffective nature) associated with the menopause period (pre- and post-menopause).
