The present invention relates to the pharmaceutical composition or the health food manufactured from the raw materials including ginsenoside Rg1 and Rb1, glycyrrhizic acid and jujuba cyclic adenosine monophosphate (jujuba cAMP) for treating depression and anxiety disorder. In particular, the present invention relates to the pharmaceutical composition or the health food for treating depression and anxiety disorder; it has definite functions and components, obvious curative effect, fewer side effects and high safety for long-term usage.
Psychological disorders are caused by brain dysfunction and afflicted individuals show abnormalities in awareness, thought, emotion, behavior, will and intelligence, etc. Psychological disorders occupy four in ten diseases, causing the most serious load in society. People are now paying more and more attention to psychological dysfunction in the course of social development. The medical community and the society as a whole are urgently seeking psychological medicine to combat psychological disorders. Anxiety disorder and depression are the most common psychological dysfunction, with anti-anxiety and anti-depression pharmaceuticals being the main method of treatment.
Anxiety disorder is a psychological disease manifest mainly as anxious emotion. The main characteristics are breakout or continuous anxious emotions such as anxiety, catatonia and fear, etc., in combination with syndromes such as autonomic nerves disturbance, muscle rigidity and exercise disturbance, etc. Since Sigmund Freud had separated anxiety disorder from neurasthenia, scholars around the world have begun large-scale studies on anxiety disorder and have accumulated a large amount of data. According to modern medical research, the etiology of anxiety disorder includes defects in psychological anatomy, neurotransmitter/modulator-receptor and neuro-endocrine system, etc.
The current mainstream anti-anxiety medicine is benzodiazepine the mechanism of which is to modulate the activity of the inhibitory neurotransmitter, gamma-aminobutyric acid (GABA), to reduce and relieve the symptoms. However, benzodiazepine has many side effects including insomnolence, allergy, muscle pain, weakness, nausea, exercise dysfunction, blurred vision, weariness, disturbance and delusion, etc.
Depression is a common disease. World Health Organization (WHO) published, “The incidence of depression in the world is about 11%. At present, there are about 340 million psychological depressed patients in the world, and the number is increasing.” The investigation is found that depression will be increased to be the number two common disease in the world from now on to 20 years later.”
The current mainstream anti-depression pharmaceuticals are Prozac, Paxil and Zoloft, etc., which belong to selective serotonin reuptake inhibitor (SSRI), serotonin-norepinephrine reuptake inhibitor (SNRI), and norepinephrine and dopamine reuptake inhibitor (NDRI), inhibiting the uptake of 5-hydroxytryptamine (5-HT), norepinephrine (NE) and dopamine (DA). The mechanism by which these anti-depression pharmaceuticals function is by increasing the amount of human neurotransmitters such as 5-HT so as to alleviate the symptoms of depression. However, the marketed anti-depression pharmaceuticals have side effects with different levels, such as increased suicide rate, headache, giddiness, vertigo, insomnolence, hypersomnia, tinnitus, thirsty, apocleisis, orexis, increased body weight, increased blood pressure, stomach upset, regurgitation nausea, emesis, dyspepsia, diarrhea, constipation, leg pain, skin rash, dither, convulsions, hyperhidrosis, edema, sexual appetite and impotence, etc.
In recent years, anti-depression pharmaceuticals, such as Prozac, etc., had become a serious social problem. In 2004, the Food and Drug Administration (FDA) of the United States further mandated the pharmaceutical companies to revise product labels to clearly state the side effects and cautions in the instructions of 32 major anti-depression pharmaceuticals in the market, and emphasized to physicians and nurses that these pharmaceuticals might increase children's and adolescents' suicide rates. However, many depression patients having therapeutic condition and therapeutic aspiration stop or refuse their therapies due to worries about or inability to withstand many side effects of the present anti-depression pharmaceuticals. In light of the current situation, the search for a new generation of pharmaceuticals with fewer side effects, high safety for long-term usage and more pronounced/potent anti-depression and anti-anxiety qualities has become the center of attention of the entire pharmaceutical world.
It is therefore attempted by the applicant to deal with the above situation encountered in the prior art.
The purpose of the present invention is to provide a pharmaceutical composition or a health food to overcome the insufficiency of the currently available treatments for depression and anxiety disorder. The pharmaceutical composition or a health food is manufactured from the raw materials including ginsenoside Rg1 and Rb1, glycyrrhizic acid and jujuba cAMP for treating depression and anxiety disorder. In particular, the new technical scheme offering definite functions and components, obvious curative effect, fewer side effects and high safety for long-term usage is provided.
The resolving scheme of the pharmaceutical of the present invention is the result endeavored by the inventor in accordance with the pathological and pharmacological theories of modern medicine for treating depression and anxiety disorder. The scheme, employing three raw materials including ginseng, liquorice and jujuba, is developed based on the pathological and pharmacological theories of modern medicine for treating anxiety; specifically, it integrates past pharmaceutical-targeted research with the recent knowledge developed in post-receptor mechanism. Ginsenoside from ginseng has adenylate cyclase (AC) activity to stimulate cAMP synthesis and cAMP phosphodiesterase (CAPD) inhibitory activity to reduce cAMP breakdown; glycyrrhizic acid (and glycyrrhetinic acid) from liquorice are strong inhibitors of CAPD. Ginsenoside Rg1 and Rb1 and glycyrrhizic acid when paired and used collectively further increase the concentration and activity of cAMP and protein kinase A (PKA) respectively in the organism. The increasing concentration and activity of cAMP can (1) increase the synthesis and release of the neurotransmitter such as norepinephrine, etc., (2) increase the expression of the brain-derived neurotrophic factor (BDNF), and (3) inhibit the hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis and the secretion of glucocorticoid, so as to achieve the significant anti-depression function. The increasing concentration and activity of PKA can magnify the inhibition function of GABA on neurons, so as to achieve the significant anti-anxiety function. In addition, jujuba cAMP being the extrinsic non-hydrolyzable cAMP can participate in the metastasis of cAMP in the organism, simulate the enzyme function and increase the expression of cAMP and PKA in the organism, so as to achieve the anti-depression and anti-anxiety functions. Therefore, ginsenoside Rg1 and Rb1 are paired with glycyrrhizic acid and jujuba cAMP; these raw materials are expected to act collectively to further increase the anti-depression effect and the anti-anxiety effect of the present invention. Ginseng, liquorice and jujuba are commonly used pharmaceutical materials and food in Chinese medicine and have been used in dietary nourishing medicinal meals for several thousand years. In this long clinical and dietary history, the safety and efficacy of combined use of ginseng, liquorice and jujuba have been sufficiently proven. The inventor's research and experimental results have shown that if these three pharmaceutical materials are only normally decocted and extracted to obtain the extract, the extract does not have significant anti-depression and anti-anxiety effects compared with the mainstream anti-depression and anti-anxiety pharmaceuticals of the present technology. However, upon further purification of the extract of these three pharmaceutical materials to increase the concentration of the effective components containing ginsenoside Rg1 and Rb1, glycyrrhizic acid and jujuba cAMP, etc., as described in this invention, a pharmaceutical composition with significant anti-depression and anti-anxiety function is obtained. The experimental result has proven that the present invention has significant anti-depression and anti-anxiety effects compared with the mainstream pharmaceuticals, Paroxetine and Diazepam, for treating depression and anxiety disorder respectively. The debris resulting from the three pharmaceutical materials after extraction and purification was also collected and tested in animal experiments. Although the debris contains a trace amount of ginsenoside Rg1 and Rb1, glycyrrhizic acid and jujuba cAMP, it does not show significant anti-depression and anti-anxiety functions in the animal experiments. Importantly, taking ginseng, liquorice and jujuba would not generate the side effects of the mainstream anti-depression and anti-anxiety pharmaceuticals of the present technology. Patients will not need worry about the side effects so they will not cease or refuse the pharmaceutical therapy forever. Therefore, the inventor submits that ginsenoside Rg1 and Rb1, glycyrrhizic acid and jujuba cAMP are the raw materials for manufacturing the pharmaceutical composition or the health food for treating depression and anxiety disorder. In particular, the new technical scheme offers definite functions and components, high safety for long-term usage without side effects, substantially improving the drawbacks generated in the prior art.
Glycyrrhetinic acid has higher liposolubility than glycyrrhizic acid and can easily enter the brain through the blood-brain barrier. Since the glycyrrhizic acid is converted to glycyrrhetinic acid in the human body with almost 100% efficiency, the inhibition of CAPD by glycyrrhizic acid is proceeded by transforming glycyrrhizic acid to glycyrrhetinic acid in the body. Accordingly, glycyrrhizic acid or glycyrrhetinic acid can be the raw material for manufacturing the pharmaceutical composition of the present invention.
