The present invention relates to a composition comprising B vitamins and C vitamins, in particular to a composition comprising B vitamins and C vitamins for promoting motility of the gastrointestinal system. The present composition is suitable for the prevention and/or treatment of conditions or diseases associated with deficiencies of gastrointestinal motility.
Nowadays, the pressure of people's life is generally increasing, the pace of life is accelerating, and the competition is fiercer day by day. More and more patients are suffering from gastrointestinal disorders or gastrointestinal discomfort. The pathogeny thereof is extensive, and the symptoms thereof are also different.
Gastrointestinal (GI) motility is a coordinated neuromuscular process that transports nutrients through the digestive system. Impaired motility of the gastrointestinal system can be involved in gastroesophageal reflux disease, gastroparesis (e.g., diabetic and postsurgical gastroparesis), irritable bowel syndrome (IBS), ileus, and constipation (e.g., functional or drug-induced constipation), and is one of the largest health care burdens of industrialized nations. In view of the above, a way to effectively stimulate motility of the gastrointestinal system is highly desirable and would be an advance in the art.
Functional dyspepsia and chronic gastritis often have such symptoms as abdominal fullness, upper abdominal pain, nausea, anorexia and so on. An important reason for this kind of symptoms is delayed gastric emptying caused by gastrointestinal motility disorders. And gastrointestinal motility disorders tend to cause IBS. Currently, drugs for treatment of gastrointestinal motility include metoclopramide, domperidone and itopride.
In the past, there were many kinds of drugs for treatment of gastrointestinal diseases, but few drugs have good curative effects and no side effects, and drugs or health care products with long-term health care effects as well as improving gastrointestinal function, promoting gastrointestinal motility and relieving gastrointestinal discomfort symptoms are even rare.
As mentioned above, (1) metoclopramide as a dopamine receptor blocking drug with strong central anti-vomiting and gastrointestinal tract excitement effects, can inhibit the relaxation of gastric smooth muscle, increase the response of gastrointestinal smooth muscle to cholinergic, accelerate gastric emptying, and increase the activity of the gastric antrum. In addition, the drug also has the function of stimulating the release of prolactin. The side effects of Metoclopramide commonly include lethargy, irritability, fatigue, and weakness. Moreover, high-dose or long-term use of the drug may block the dopamine receptor, showing the symptoms of Parkinson's disease. (2) Domperidone as a peripheral dopamine receptor antagonist can promote upper gastrointestinal peristalsis and tension recovery, facilitate gastric emptying, increase the movement of gastric antrum and duodenum, coordinate pyloric contraction, and enhance esophageal peristalsis and the tension of the lower esophageal sphincter. Because of its poor penetration into the blood brain barrier, domperidone almost has no antagonistic effect on the dopamine receptor in the brain. It is reported abroad that its high-dose intravenous injection may cause seizures (there is no this preparation in China). This drug, however, is a powerful prolactin-releasing drug which may cause menstrual disorders. (3) Itopride has dual effects of dopamine receptor blockade and acetylcholinesterase inhibition. It can enhance the movement of stomach and duodenum and facilitate gastric emptying by stimulating the release of endogenous acetylcholine and inhibiting the hydrolysis thereof. It also has a moderate anti-vomiting effect. The elderly or aged patients should use this drug with caution.
B vitamins are all water soluble, most of which are coenzymes, taking part in the in vivo metabolism of sugar, protein and fat.
Vitamin B1 (thiamine) can promote gastrointestinal peristalsis and increase appetite. Vitamin B1 can inhibit the activity of cholinesterase to hydrolyze acetylcholine. Lack of vitamin B1 may increase the activity of cholinesterase and accelerate the hydrolysis of acetylcholine. Acetylcholine is an important neurotransmitter and its deficiency can lead to nerve conduction disorders, especially affecting the nerve conduction at the gastrointestinal tract and gland, and lead to slow gastrointestinal peristalsis, abdominal distension, diminished digestive glandular secretion, and appetite decrease.
Vitamin B2 constitutes many important coenzymes in the flavoproteins. It can be converted into flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), both of which are important coenzymes in the tissue respiration, function to transfer hydrogen in the enzyme system, and participate in the metabolism of sugar, protein and fat, and can maintain normal visual function. Furthermore, Vitamin B2 can activate Vitamin B6 and convert tryptophan into niacin, and may be related to maintaining the integrity of red blood cells. It can maintain and improve the health of epithelial tissue, such as the gastrointestinal mucosal tissue. When the human body lacks B2, especially in severe deficiency status, the mucosal layer of human body cavity will have problems that cause mucosal lesions, and this can enhance the carcinogenic effect of chemical carcinogens. Vitamin B2 can thus prevent cancer.
Vitamin B3 (niacin) constitutes a coenzyme of dehydrogenase in the body. Vitamin B3, as the most requisite amount of B vitamins of the human body, not only keeps health of the digestive system, but also alleviates gastrointestinal disorders. Niacin is converted into nicotinamide in the human body. Nicotinamide is a component of coenzyme I and coenzyme II and participates in the in vivo lipid metabolism, oxidation process of tissue respiration, and the anaerobic decomposition of carbohydrates. It can keep the health of the digestive system, relieve gastrointestinal disorders, and effectively relieve the symptoms of constipation. Its deficiency can lead to angular cheilitis, glossitis, diarrhea, and so on. Diarrhea is a typical symptom of this disease. Constipation often occurs in its early days. Then it is often accompanied by diarrhea because of enteritis and the atrophy of the intestinal wall, digestive gland, intestinal wall and mucosa, and intestinal villus. The stool is watery or pasty, with large quantities and a lot of stink and sometimes with blood. Tenesmus may happen when the lesion is near the anus. Diarrhea is often severe and refractory and can be combined with absorption disorders.
Vitamin B5 (pantothenic acid) has an active form of coenzyme A, is an acyl carrier in vivo, and participates in the metabolism of sugar, fat, and protein. They work synergistically to regulate metabolism, maintain skin and muscle health, enhance the functions of the immune system and nervous system, and promote cell growth and division (including promotion of production of red blood cells and prevention of anemia). The lack of vitamin B5 may lead to the symptoms including anepithymia, dyspepsia, and being susceptible to duodenal ulcer.
Vitamin B6 comprises pyridoxine, pyridoxal and pyridoxamine, which can be transformed to one another. It can react with ATP in vivo via an enzyme and then be transformed into a coenzyme of a variety of enzymes having physiological activity, thereby participating in various metabolic functions of amino acids and fats. Combined with vitamin B1, it has a strong analgesic effect. Vitamin B12 can enhance the analgesic effect by the combination of the above two, and relieve the pain caused by peripheral nerve disease and spinal cord disease. Studies have reported that the intravenous drip of vitamin B6 mixed with azithromycin can reduce side effects of azithromycin on the gastrointestinal tract. Its main targets are blood, muscle, nerves, skin, etc. Its functions are the synthesis of antibodies, production of gastric acid in the digestive system, utilization of fat and protein (which should be supplemented especially on a diet), and the maintenance of the sodium/potassium balance (stabilization of the nervous system). Lack of vitamin B6 damages cells and affect humoral immunity. Feeding of vitamin B6 can improve immunity, reduce carcinogens in the body, and has a certain anticancer effect.
Vitamin B7, also known as vitamin H, biotin, and coenzyme R, is involved in the metabolism of fatty acids and carbohydrates in the body, promoting protein synthesis. It also involved in the metabolism of vitamin B12, folic acid, and pantothenic acid. It can promote urea synthesis and excretion, enhance the body's immune response and resistance to infection, stabilize the lysosomal membrane of normal tissues, maintain the body's humoral immunity and cellular immunity, affect the secretion of a series of cytokines, improve the body's immune function, and reduce the symptoms of perianal eczema and itching. The biotin side chain carboxyl group can be linked to the lysine residues of the enzyme via an amide bond. Biotin is a carboxyl carrier and is also involved in the metabolism of vitamin B12, folic acid, and pantothenic acid.
Vitamin B9 (folic acid) belongs to water-soluble B vitamins consisting of pteridine, p-aminobenzoic acid, and glutamic acid residues. The drug is absorbed by the intestinal tract and then passes through the portal vein into the liver, where it is converted into an active tetrahydrofolic acid under the action of the dihydrofolate reductase. Tetrahydrofolic acid is the carrier of “one carbon group” in the body. The “one carbon group” can be linked to the tetrahydrofolic acid at its 5 or 10-position carbon atom, and is mainly involved in the synthesis and transformation of purine nucleotides and pyrimidine nucleotides. The methyl group required for conversion of uracil nucleotides to thymidine nucleotides is derived from the methylene group provided by tetrahydrofolic acid bearing a “one carbon group”. As a result, folic acid deficiency can result in a “one carbon group” transfer barrier, and a difficult synthesis of thymidine nucleotide, thereby affecting DNA synthesis and slowing down the rate of cell division, that is, the cell cycle will only stay in the G1 phase and the S and G2 phases will be relatively prolonged. The above changes will affect not only hematopoietic cells (causing the megaloblastic anemia) but also the somatic cells (especially the digestive tract mucosal cells). Folic acid deficiency can lead to B1 absorption disorders. The health benefits of folic acid for women are widely noted in the medical community, and pregnant and lactating women should be supplemented with folic acid. Besides, it can be used to prevent rectal cancer and heart disease. It has also been found to prevent free radicals from destroying chromosomes. Humans with deficient folic acid may suffer from megaloblastic anemia and leukopenia.
Deoxyadenosine cobalamin is the main existing form of vitamin B12 in the body and is a cobalt-containing red compound that is active only after it is converted to methylcobalamin and coenzyme B12. Vitamin B12 and folic acid play an important role in DNA synthesis. In addition, vitamin B12 also plays an important role in the maturation of red blood cells and in the normal maintenance of the nervous system. It is often associated with the role of folic acid. Folic acid has multiple coenzyme forms in the cell, and some studies have suggested that folic acid can intervene in the occurrence of gastrointestinal cancer and that folic acid can treat atrophic gastritis and improve gastric mucosal pathology.
Choline bitartrate has the effect of promoting the transformation of phospholipids and accelerating the operation of fat, and has a cholagogic effect; inositol can promote cell metabolism, promote development, and increase appetite. P-aminobenzoic acid (PABA) is actually a component of folic acid and it functions as a coenzyme in the body. PABA works with folic acid to promote protein metabolism and blood cell production.
Vitamin C, also known as ascorbic acid, is one of antioxidant vitamins. It participates in hydroxylation reaction in the body and is required for the formation of bones, teeth, and the interstitial adhesions in connective tissues and non-epithelial tissues. It can maintain the normal function of the teeth, bones, and blood vessels, and increase resistance to diseases. It is reported that vitamin C is deficient at different levels in various populations. When the body has some small problems, people should promptly be supplemented with vitamins and minerals to improve nutrition deficiencies, especially the elderly should pay more attention. Vitamins have a preventive effect on many diseases, many diseases may be more or less related to the lack of vitamin C, and vitamin C can also be combined with many other drugs to treat some diseases. Vitamin C is an antioxidant that protects the body from the threat of free redicals. Vitamin C is also a coenzyme. Many studies have shown that vitamin C can block the synthesis of carcinogenic N-nitroso compounds, prevent the formation of carcinogenic ammonium nitrate in the salted, pickled, and smoked foods containing nitrite (bacon, sausage, and so on), and prevent cancer, especially it has a better preventive effect on rectal cancer and colon cancer. At the same time, it has the effect of softening the blood vessels of the anus and increasing the elasticity of the anus. VC is easily damaged by heat or oxidants, especially light, trace heavy metals, and fluorescent substances can promote its oxidation, which makes VC be greatly restricted in application. Therefore, derivatives of vitamin C, including metal salts of VC, esters generated by VC with various acids, and compounds of VC and carbohydrates, etc., not only can get rid of the instability nature of VC, but also can better exert the physiological function of VC. These derivatives include vitamin C (L-ascorbic acid), Sodium ascorbate (L-sodium ascorbate), magnesium ascorbyl phosphate, L-Ascorbate-polyphosphate, ascorbyl palmitate, ascorbin stearate, vitamin C and glucose compound, etc.
From the perspective of mechanism of action, vitamin B is an important coenzyme involved in energy metabolism of human body, and vitamin C can promote the body's absorption of members of B vitamins. Multivitamin B C is used to improve the energy metabolism of the human body and provide more energy for the gastrointestinal tract to improve the functional dyspepsia caused by inadequate gastrointestinal motility. The mechanism for the increase in energy metabolism includes assisting carbohydrates and fat in releasing energy, decomposing amino acids, and transporting nutrient-containing oxygen and energy throughout the body. Multivitamin BC will be likely to become a new drug or health food with higher safety for promoting the motility of gastrointestinal system, yet there is no evidence to date to prove the ability of vitamin B and vitamin C to promote the motility of the gastrointestinal system, especially the therapeutic and regulatory effect of vitamin B and vitamin C on motility disorders of the gastrointestinal system in pathological state. Due to the large number of family members of B vitamins and their interdependent relationship, component selection and compatibility of the B vitamins are very important for preparation of drugs or health food for the treatment or regulation of motility disorders of the gastrointestinal system.

The purpose of this study was to evaluate the therapeutic effects of different prescriptions of multivitamin BC tablets in mice constipation model induced by loperamide.
Species: mouse
Gender and quantity: Male, 80
Animal week-age: 6-8 weeks
Weight range: 17.0-20.0 g
Animal sources: Shanghai Lingchang Biotechnology Co. LTD
Animal certificate number: 2013001820135
Experimental animals were randomly divided into 8 groups, 10-12 animals per group by the random number table method. The doses and multivitamin BC tablets prescriptions for each groups are shown in Table 1 and Table 2.
After fasting and freely drinking for about 22-24 hours, each group of the mice were administrated at above doses at 20 ml/kg, and the model group and the control group were intragastrically administrated with 0.5% CMC-Na solution at the same dose. After 30 minutes of administration, the control group was injected subcutaneously with the saline solution containing 1.0% Tween 80 while the other groups were injected subcutaneously with loperamide in an injection volume of 10 ml/kg. After a subcutaneous injection for 30 minutes, an intragastric administration of the charcoal solution was performed at an administration volume of 10 ml/kg.
Small intestinal propulsive rate (%)=(the propulsive distance of the charcoal solution/the total length of the small intestine)×100
Twenty minutes after an intragastric administration of the charcoal solution, the animal was sacrificed by cervical dislocation and its abdominal cavity was immediately opened to separate the mesentery. The intestinal canal from the pylorus to the ileocecal junction was carefully removed and put on a tray. Be careful not to involve the small intestine, gently place the small intestine in a straight line, and measure the total length of the small intestine. The length from the pylorus to the front of the charcoal solution is the propulsive distance of the charcoal solution, and the small intestinal propulsive rate (%) of the charcoal solution was calculated.
Experimental data were expressed by Mean±SE and one-way ANOVA was performed by SPSS. Comparison between groups was made using LSD test.
Effects of the different multivitamin BC tablets prescriptions on the small intestinal propulsive distance and propulsive rate (%) of the charcoal solution in the mice are shown in Table 3 and
The results showed that compared with the control group, the small intestinal propulsive rate (%) of the model group was significantly reduced (64.5±8.5 VS 28.1±5.3), indicating that the mouse constipation model was successfully prepared. Compared with model group, the small intestinal propulsive rate (%) were improved at different levels in Itopride positive control group, VBs (5×), VBs+choline (5×), VBs+VC (5×), VBs+VC+biotin (5×), VBs+VC+choline (5×) groups (28.1±5.3 VS 42.7±5.5, 42.7±12 0.4, 45 0.2±8.0, 43.0±8.2, 40.1±6.5, 52.1±6.8).
All the different multivitamin BC tablets prescriptions can improve small intestinal propulsive rate (%) of the 2.5 mg/kg loperamide-induced constipation mouse model, and the effects of VBs (5×), VBs+choline (5×), VBs+VC (5×), VBs+VC+biotin (5×), VBs+VC+choline (5×) groups were superior to Itopride positive control group.
The purpose of this study was to evaluate the therapeutic effects of different prescriptions of multivitamin BC tablets in mice constipation model induced by loperamide.
Species: mouse
Gender and quantity: Female, 40

Experimental animals were randomly divided into 8 groups, 5 animals per group by the random number table method. The doses and different multivitamin BC tablets prescriptions for each groups are shown in Table 4 and Table 5.
Free access to forage and drinking water was allowed. Each group of the mice were administrated at above doses at 20 ml/kg, and the model group and the control group were intragastrically administrated with 0.5% CMC-Na solution at the same dose. After 30 minutes of administration, the control group was injected subcutaneously with the saline solution containing 1.0% Tween 80 while the other groups were injected subcutaneously with loperamide in an injection volume of 10 ml/kg. After a subcutaneous injection for 30 minutes, an intragastric administration of the charcoal solution was performed at an administration volume of 10 ml/kg. Start time counting 15 mins after feeding charcoal, recorded the time of defecation of first black stool, the number of stools between 0-2 h and 4-6 h, weighing and measuring the dry weight (60° C., 6 h) of stools. Then calculated the stools water content (%)[(the wet stool weight−the dry stool weight)/(the wet stool weight)*100%]. Each mice was raised in a single cage during the experiment, fasted but without water deprivation. The weight of each mice was recorded before drug administration and at the end of the study, respectively.

Effects of the different multivitamin BC tablets prescriptions on the time of defecation of first black stool, the number of stools within 6 h were shown in Table 6 and
Effects of the different multivitamin BC tablets prescriptions on mice wet stool weight, dry stool weight and the stool water content within 6 h showed in Table 7, and
The results showed that compared with the control group, the time of defecation of the first black stool of the model group extended (264.2±131.18 VS 104.0±12.00). Compared with model group, the time of defecation of the first black stool in VBs (5×), VBs+VC (5×), VBs+VC+biotin (5×), VBs+VC+choline (5×) groups were shorten to a certain degree (264.2±131.18 VS 177.2±105.25, 178.8±113.19, 171.4±123.03).
Compared with the control group, the number of stools, the wet stool weight, the dry stool weight within 6 h were all decreased in model group slightly. The number of stools in VBs (5×), VBs+choline (5×), VBs+VC+choline (5×) groups were higher than the model group (2.8±1.92 VS 6.6±3.44, 4.8±2.86, 3.2±1.30). The wet stool weight of VBs (5×), VBs+choline (5×), VBs+VC+biotin (5×), VBs+VC+choline (5×) groups were greater than the model group (0.043±0.031 VS 0.092±0.040, 0.068±0.048, 0.059±0.042, 0.054±0.023). The dry stool weight of VBs (5×), VBs+choline (5×), VBs+VC+biotin (5×), VBs+VC+choline (5×) groups were greater than the model group (0.0246±0.019 VS 0.0567±0.023, 0.046±0.031, 0.026±0.014, 0.032±0.015). The stool water content of VBs (5×), VBs+VC (5×), VBs+VC+biotin (5×), VBs+VC+choline (5×) groups were slightly higher than the model group (31.59±25.82 VS 37.19±8.94, 36.56±25.03, 50.95±10.53, 38.31±18.37).
