FIELD OF THE INVENTION

The present invention relates to a pharmaceutical composition for snoring treatment, its fabrication and utilities


BACKGROUND

Snoring (obstructive sleep apnea in medical science) is a ubiquitous sleeping phenomenon. At present, most people take it as a common behavior and even think it is a sign of good sleep.


Reports show that at least 20% people snore during sleeping. In fact, snoring is harmful to heath, because snoring causes repetitive sleep apnea which is associated with reduction in blood and brain oxygen saturation, thus causing hypoxaemia and possibly hypertension, brain diseases, arrhythmia, myocardial infarction and stenocardia. Sudden death could happen if breathing during sleeping in the night pauses for over 120 seconds.


Medical research shows that snoring is mainly caused by the following three reasons:


1. Central diseases


2. Obstructive diseases


3. Combination of the above two called mixed


Generally speaking, adults' snoring is caused by mixed reasons while children's is caused by obstructive diseases. In-depth studies have determined the risk factors such as smoking, alcohol, obesity and other physiological causes (like deflection of nasal septum, other abnormalities in internal nasal structure, chronic nasal congestion, congestion in laryngeal tissue, fitness, lack of muscle tone, hypertrophy of tonsil and adenoid, and tongue swelling). Drug treatment (benzodazines and sedatives, for instance) can potentially cause muscular flaccidity, thus increase risk or tendency of snoring. Snoring is often categorized into several degrees ranging from mild to severe, including hypopnea (breathing could become astonishingly slow and shallow during this time) and apnea (breathing stops or pauses during this time). The latter is the symptom of obstructive sleep apnea (OSA) which relates to complete or partial obstructions of upper airway.


Currently, treatments for snoring are mainly surgery, drug therapy, physical intervention, etc. Surgery treatments: varied and must be chosen according to the specific airway obstructions. Nasal surgery and palatopharyngoplasty are the most common surgeries taken to treat snoring and sleep apnea. However, whether it works or not depends on the patient. This surgery also makes patients suffer a lot. Drug treatment: there are plenty of drugs domestic and overseas used to treat snoring, such as acetazolamide and thyrine. By boosting metabolism, these drugs have certain effects alleviating snoring to some extent during the therapy, but fail to cure. Physical instrument like nasal splint and cingulum rest appeared in recent years is seen less and less on market due to its limited effectiveness.


Chinese traditional medicines have years of history in treating snoring, with remarkable effects, no side-effect and extensive application.


CONTENTS OF THE INVENTION

The present invention is aimed to provide a pharmaceutical composition for snoring treatment, its fabrication and utilities.


Specifically, the present invention provides a pharmaceutical composition for snoring treatment. The crude drugs of it contain the components proportioned by the weight of:


15-25 doses of Gambir and 5-15 doses of Cassia.


The present invention unexpectedly found during study that using Gambir together with Cassia has better effect than using just Gambir, which shows that the two drugs have synergistic effect when used together in the present invention. What is more, there's no research that reports the advantages of Cassia and cassia twig, being two different parts of a plant, for snoring treatment. The present invention found out that using Cassia with Gambir generates better effects than using cassia twig with Gambir.


Gambir is dry stem and branch with hook of Uncaria rhynchophylla (Miq.) ex Havil, sweet and a bit bitter in taste and mild cold-natured. It is useful for clearing heat, calming liver wind and relieving convulsion. Modern pharmacology research has proved that Gambir can treat asthma, children convulsion, heating, and dizziness and regulate central nervous system.



Cassia is dry bark of Cinnamomum cassia Presl, acrid in taste and warm-natured. It is used to supplement kidney-yang, warm the stomach and spleen, remove internal cold and promote blood circulation. Modern pharmacology research has proved that Cassia can treat asthma and regulate central nervous system.


Crude drugs of the composition in the present invention contain components proportioned by the weight of:


15 doses of Gambir and 5 doses of Cassia; 20 doses of Gambir and 10 doses of Cassia; 25 doses of Gambir and 15 doses of Cassia.


In a detailed fabrication for the present invention, weights of of Gambir and Cassia are: 25 doses of Gambir and 15 doses of Cassia.


The present invention further found that, adding Trichosanthes, Phragmites and Turmeric to Gambir and Cassia increases effect on treating snoring, compared with using same amount of just Gambir and Cassia. Therefore, crude drugs of the composition in the present invention may contain components proportioned by the weight of: 12-18 doses of Trichosanthes, 12-20 doses of Phragmites and 6-12 doses of Turmeric.


Among which:



Trichosanthes is the root of Trichosanthes kirilowii Maxim, sweet and a bit bitter in taste and mild cold-natured. It is used to treat pyreticosis, polydipsia, lung heat, dry cough, internal heat, symptom-complex of excessive eating, swelling and ulcer on the body surface and pyogenic infections. Modern pharmacology research has proved that Trichosanthes is effective at anti-early pregnancy, anticancer, improving immunity, and antibiosis and antivirus.



Phragmites is fresh or dry rhizome of Phragmites communis Trin, sweet in taste and cold-natured. It is used to treat pyreticosis, polydipsia, stomach heat, emesis, lung heat, dry cough, pulmonary abscess, heat strangury and pain in gonorrhea. Modern pharmacology research has proved that Phragmites is effective at restraining skeletal muscle and relaxing isolated guinea pig ileum.


Turmeric is the dry rhizome of Curcuma Longa L., acrid and bitter in taste and warm-natured. It is used to treat chest pain, abdominal pain, and dysmenorrhea and limb pain caused by Qi-stagnation and blood stasis. Modern pharmacology research has proved that Turmeric has hypolipidemic, antineoplastic, anti-inflammatory and antiviral effects. It also has cholagogue effects and helps promoting cardiovascular system.


Furthermore, crude drugs of the composition in the present invention may contain components proportioned by the weight of:


15 doses of Gambir, 5 doses of Cassia, 12 doses of Trichosanthes, 12 doses of Phragmites and 6 doses of Turmeric;


20 doses of Gambir, 10 doses of Cassia, 15 doses of Trichosanthes, 17 doses of Phragmites and 9 doses of Turmeric;


25 doses of Gambir, 15 doses of Cassia, 18 doses of Trichosanthes, 20 doses of Phragmites and 12 doses of Turmeric;


The composition is fabricated by combing the active ingredients such as power, aqueous extract and alcohol extract of the crude drugs with common pharmaceutical auxiliaries or auxiliary materials.


Pharmaceutical auxiliaries mentioned in the present invention refer to substances in the composition apart from active ingredients, including but not limited to filler (diluent), lubricant (glidant or antitack agent), dispersant, humectant, adhesive, modifier, solubilizer, antioxygen, bacteriostatic agent, emulsifier and disintegrating agent. Adhesives include syrup, Arabic gum, gelatin, sorbitol, tragacanth, cellulose and its derivatives (such as microcrystalline cellulose, sodium carboxymethylcellulose, ethyl cellulose, hydroxypropyl methyl cellulose), gelatin mucilage, syrup, starch slurry and polyvinylpyrrolidone; filler includes lactose, powdered sugar, dextrin, starch and its derivatives, cellulose and its derivatives, inorganic calcium salt (such as calcium sulfate, calcium phosphate, calcium hydrophosphate, calcium carbonate), sorbitol and glycine; lubricants include aerosol, magnesium stearate, talcum powder, aluminium hydroxide, boric acid, hydrogenated vegetable oil and polyethylene glycol; dispersants include starch and its derivatives (such as sodium carboxymethyl starch, sodium glycollate starch, pregelatinized starch, modified starch, hydroxypropyl starches, corn starch, etc.), polyvinylpyrrolidone and microcrystalline cellulose; humectants include lauryl sodium sulfate, water or alcohol; antioxygens include sodium sulfite, sodium hydrogen sulfite, sodium pyrosulfite and dibutyl benzoic acid; bacteriostatic agents include 0.5% phenol, 0.3% cresol and 0.5% chloretone; modifiers include hydrochloric acid, citric acid, potassium (sodium) hydroxide, sodium citrate and buffer agents (including sodium dihydrogen phosphate, disodium hydrogen phosphate, etc.); emulsifiers include polysorbate-80, fatty acid sarbitan, pluoronic F-86, lecithin and fabaceous lecithin; solubilizers include Tween 80, bile and glycerine.


Pharmaceutically auxiliary ingredients mentioned in the present invention, though have certain physiological activity, won't affect the composition or derivative's taking dominant role in treating diseases. They will only have an auxiliary effect which is the result of utilization of the known activity of them. They are in common use for auxiliary treatment in pharmaceutical field. Adding these auxiliary ingredients in use with the composition of the present invention also falls within protection of the present invention.


Furthermore, the said dosage form is the form of gastrointestinal absorption; the dosage form will be medical liquor, oral liquid, drink, granules, powder, pills, troche or capsule.


The present invention also provides fabrication of the said pharmaceutical composition. Here are the steps:


(1) Take crude drugs according to the formula proportion;


(2) Take the crude drugs and mix them up for aqueous extraction, or extract the crude drugs respectively. Then take the aqueous extractives out for use in next step.


(3) Add common pharmaceutical auxiliaries or auxiliary materials into the aqueous extractives and the composition is made.


Furthermore, extraction method used in step (2) is decoction or ultrasound.


Adding either aqueous extractives or powder in drug is a traditional way used in Chinese traditional medicine. After extracted in water, most of the effective components will come out, since water has high dissolving capacity, which will make it easier for the drug to be absorbed in human body and render better effects. Decoction, for instance, is such kind of dosage form. Adding powder, on the other hand, with relatively large surface area, is also good for absorption of effective components inside body. However, since the drug has not been extracted, the effective components has to be dissolved inside the body and then be absorbed, which makes it slower to take effects, compared with aqueous extractives. Meanwhile, it reduces toxic and side effects of the harmful substances in the medicine. It is suitable for long-term therapy. Making the crude powder into pills, for example, is such kind of dosage form. At present, using ethanol as the solvent to extract drugs is the most common way in pharmaceutical process. Ethanol is a semi-polar solvent. Its dissolving capacity falls between that of polar and non-polar solvent. It can dissolve some water-soluble components and some components that can only be dissolved by non-polar solvent. Using ethanol extraction instead of decoction by water can prevent large amounts of inactive substances from coming out, thus increase concentration and extraction efficiency of effective components. But ethanol costs more than water. Therefore, in modern pharmaceutical production, to save cost of production, water decoction is still adopted most. As long as the physiological activity of the aqueous extractives from the composition in the present invention, water decoction, crude powder, ethanol extraction or mix of the former three can be used to fabricate specific dosage form, to meet needs of production and usage.


The present invention also provides the said pharmaceutical composition's utilities in making drugs for snoring treatment.


The present invention provides composition of Gambir, Cassia, Trichosanthes, Phragmites and Turmeric which has remarkable effects on improving or inhibiting snoring and has no side-effects. It can be a new choice for clinical treatment of snoring since it has no surgery risks.

Take products fabricated with composition of the present invention in Example 4. Dosage is 2 troches, 0.25 g in each troche (equals to 12 g of crude drug), before going to bed; analyze statistics of effects on 120 sleep apnea patients.


Symptoms of Sleep Apnea are Mainly:


Daytime: clinical symptoms are sleepiness, fatigue, hypomnesis, dyspnea chest discomfort, irritability, headache in the morning, dizziness and thirsty and throat ache. Standard symptoms shall be diagnosed by the pause times and duration of sleep apnea.


Nighttime: clinical symptoms are snoring, frequent pause of breathing, abnormal sleep actions; insomnia, dreaminess, labored breathing, polyuria and enuresis.


Degrees are mild, moderate and severe.


Mild patients suffer 30-50 times of apnea/seven hours, pause duration 10-30 seconds;


Moderate patients suffer 50-100 times of apnea/seven hours, pause duration 30-60 seconds;


Severe patients suffer 100-200 times of apnea/seven hours, pause duration 60+seconds;


Among the 120 patients, 80 are male and 40 are female, aging from 36-82. 60 of them are mild patients, 40 are moderate and 20 are severe.


Treatment: take the medicines with warm water every night before going to bed. 7 days are a therapy.


Evaluation standard for efficacy: effective: snoring sound lowered, times of awakening by labored breathing reduced, fatigue and restlessness during sleep disappeared, energetic during daytime, dizziness and tiredness disappeared.


Obvious efficacy: snoring sound lowered, thirstiness disappeared, never awakened by labored breathing, no sleepiness during daytime.
