## Background
PRIORITY CLAIM
This application claims the benefit of the filing date of Taiwan Patent Application No. 103110986, filed Mar. 25, 2014, entitled “INHALATION-TYPE PHARMACEUTICAL COMPOSITION FOR THE TREATMENT OF ALZHEIMER'S DISEASE AND PREPARATION METHOD THEREOF,” and the contents of which are hereby incorporated by reference in their entirety.
FIELD OF THE INVENTION
The present invention relates to an inhalation-type pharmaceutical composition and the preparation method thereof, more particularly, to the inhalation-type pharmaceutical composition used for the treatment of Alzheimer's disease and the preparation method thereof.
BACKGROUND
The main clinical feature of Alzheimer's disease (AD) is a cognitive decline that leads to progressive memory loss and impairment in language and emotion. Therefore, the patient care and the treatment of the Alzheimer's disease are expensive and degraded quality of life for patient's families.
Therefore, the treatment of Alzheimer's disease has become a very important topic. Nowadays, the U.S. Food and Drug Administration (FDA) has approved two types of medications for the management of Alzheimer's disease: N-methyl-D-aspartate receptor antagonist including memantine hydrochloride and cholinesterase inhibitors including rivastigmine hydrogen tartrate, donepezil hydrochloride, and galantamine hydrobromide. Those aforementioned approved pharmaceuticals can inhibit cholinesterase, repress the hydrolysis of neurotransmitter acetylcholine, and increase the acetylcholine content in human brain, which in turn may improve symptoms and defer the process of memory-loss. However, those pharmaceutical treatments are unable to cure Alzheimer's disease, but only relieve certain AD symptoms. Furthermore, those medications will bring some side effects to AD patients, including nausea, headache, diarrhea, insomnia, pain, hallucination, or dizziness, etc.
Therefore, the current treatment for Alzheimer's disease lacks a medicine combined with the curative effect for Alzheimer's disease and without side effects to patients.

Then, the hydrogen provided by the hydrogen bottle is mixed with the atomized medicine, where at this time the gas volume concentration of hydrogen in the inhalation-type pharmaceutical composition is larger than 66.66%, for example between 67 to 96%. In another embodiment of the present invention, the hydrogen can also be directly collected from the hydrogen generated in the electrolyzed water. The hydrogen is then collected from the hydrogen generated in the electrolyzed water, not the gas mixture of hydrogen and oxygen, and is directly mixed with the atomized medicine, where at this time the gas volume concentration of hydrogen in the inhalation-type pharmaceutical composition will also be larger than 66.66%.
Please refer to FIG. 1. FIG. 1 is a method flowchart illustrating a preparation method for an inhalation-type pharmaceutical composition for the treatment of Alzheimer's disease according to one embodiment of the present invention. As shown in FIG. 1, the preparation method for the inhalation-type pharmaceutical composition of the present invention comprises the following steps:
(S1) preparing a first gas, wherein the first gas comprises hydrogen;
(S2) atomizing a medicinal liquid in order to generate an atomized medicine, wherein the atomized medicine is selected from a group comprising rivastigmine hydrogen tartrate, donepezil hydrochloride, galantamine hydrobromide, memantine hydrochloride, and any combination thereof; and
(S3) mixing the first gas and the atomized medicine in order to generate the inhalation-type pharmaceutical composition, wherein the gas volume concentration of hydrogen in the inhalation-type pharmaceutical composition is between 2 to 96%.
According to the preparation method for the inhalation-type pharmaceutical composition for the treatment of Alzheimer's disease provided by one embodiment of the present invention, the first gas is generated by electrolyzing water in step (S1) of the present invention. The first gas comprises a gas mixture of hydrogen and oxygen, where the volume ratio of hydrogen to oxygen is 2:1. In the embodiment, the gas volume concentration of hydrogen in the inhalation-type pharmaceutical composition is between 2 to 66.66%, but is not limited to this range.
Please refer to FIG. 2. FIG. 2 is a method flowchart illustrating a preparation method for an inhalation-type pharmaceutical composition for the treatment of Alzheimer's disease according to another embodiment of the present invention. As shown in FIG. 2, another preparation method for the inhalation-type pharmaceutical composition of the present invention comprises the following steps:
(S21) preparing a first gas, wherein the first gas comprises hydrogen;
(S22) atomizing a medicinal liquid in order to generate an atomized medicine, wherein the atomized medicine is selected from a group comprising rivastigmine hydrogen tartrate, donepezil hydrochloride, galantamine hydrobromide, memantine hydrochloride, and any combination thereof;
(S23) preparing a second gas; and
(S24) mixing the first gas, the second gas, and the atomized medicine in order to generate the inhalation-type pharmaceutical composition.
According to the preparation method for the inhalation-type pharmaceutical composition for the treatment of Alzheimer's disease provided by one embodiment of the present invention, the first gas is generated by electrolyzing water in step (S21) of the present invention. The first gas comprises a gas mixture of hydrogen and oxygen, where the volume ratio of hydrogen to oxygen is 2:1. Furthermore, the gas volume concentration of hydrogen in the inhalation-type pharmaceutical composition can be reduced by adding the second gas. In the present embodiment, the gas volume concentration of hydrogen in the inhalation-type pharmaceutical composition is between 4.7 to 66.66%, but is not limited to this range.
In another embodiment of the present invention, the required hydrogen can also be provided by using a hydrogen bottle. The hydrogen provided by the hydrogen bottle is then mixed with the atomized medicine, where at this time the gas volume concentration of hydrogen in the inhalation-type pharmaceutical composition is larger than 66.66%, for example between 67 to 96%. When a user inhales gas with higher gas volume concentration of hydrogen, such as the gas volume concentration of hydrogen being higher than 96%, namely gas inhaled by the user has lower gas volume concentration of oxygen, which would result in lack of oxygen to the user's body. Therefore, it is imperative that the invention controls the volume concentration of hydrogen to not be higher than 96%, for example having the gas volume concentration of hydrogen in the inhalation-type pharmaceutical composition to be between 67 to 90%. In another embodiment of the present invention, hydrogen can also be directly collected from the hydrogen generated in the electrolyzed water. The hydrogen collected from the hydrogen generated in the electrolyzed water, not a gas mixture of hydrogen and oxygen, is directly mixed with the atomized medicine, where at this time the gas volume concentration of hydrogen in the inhalation-type pharmaceutical composition will also be larger than 66.66%.
Please refer to FIG. 3. FIG. 3 is a schematic diagram of an electrolysis device illustrating step (S1) in the preparation method for an inhalation-type pharmaceutical composition for the treatment of Alzheimer's disease according to one embodiment of the present invention. In the present embodiment, the first gas comprising the gas mixture of hydrogen and oxygen can be generated by electrolyzing water, wherein an electrolysis device 100 comprises an electrolysis tank 102, electrolytic water 104, two electrodes 106A and 106B, and a power supply.
Firstly, the electrolysis tank 102 is used to accommodate the electrolytic water 104, wherein the main ingredient of the electrolytic water 104 is pure water, but is not limited thereof. In practical application, electrolytes such as sodium hydroxide, calcium carbonate and sodium chloride can be added into the electrolyzed water 104 as needed. Then, the electrolysis tank 102 comprises two electrodes 106A and 106B, wherein the two electrodes 106A and 106B respectively represent a cathode electrode and an anode electrode. The two electrodes 106A and 106B are coupled to a power supply (not shown) in order to provide the required power to electrolyze the water. In one embodiment of the present invention, the polarity of the two electrodes 106A and 106B are fixed, for example, the electrode 106A is the cathode and the electrode 106B is the anode. In another embodiment of the present invention, the polarity of the two electrodes 106A and 106B can be alternated. For example, at a point in time, the electrode 106A is the cathode and the electrode 106B is the anode, but after a predetermined time, the electrode 106A changes into the anode and the electrode 106B changes into the cathode.
After the two electrodes 106A and 106B are powered, the water 104 in the electrolysis tank 102 will begin to be electrolyzed in order to generate hydrogen and oxygen. Hydrogen is generated on the cathode and oxygen is generated on the anode, and both hydrogen and oxygen are released to the upper part of the electrolysis tank 102 in order to form a first gas 108. The first gas 108 is outputted from a first gas line 110 of the electrolysis tank 102 to be used, but is not limited thereof. In another embodiment of the present invention, hydrogen from the cathode and oxygen from the anode are outputted to the electrolysis tank 102 through a gas pipe and then mixed to form the first gas 108.
Hydrogen and oxygen are generated from electrolyzing the water 104, where the volume ratio of hydrogen to oxygen is 2:1. In one embodiment of the present invention, the invention can further add a second gas 112 to the inhalation-type pharmaceutical composition to reduce the gas volume concentration of hydrogen in the inhalation-type pharmaceutical composition. For example, the gas volume concentration of hydrogen in the inhalation-type pharmaceutical composition can be controlled to be between 4.7 to 66.66%. The second gas is a gas selected from a group comprising air, water vapor, inert gas, oxygen or any combination thereof.
Please refer to FIG. 4. FIG. 4 is a schematic diagram of a gas mixing system illustrating step (S2) and (S3) in the preparation method of an inhalation-type pharmaceutical composition for the treatment of Alzheimer's disease according to one embodiment of the present invention. In step (S2) and (S3) of the preparation method, a medicinal liquid 220 can be atomized by a gas mixing system 200, and then the atomized medicinal liquid 220 can be mixed with the first gas 108 in order to generate an inhalation-type pharmaceutical composition 214.
The gas mixing system 200 comprises an atomized/volatile gas mixing tank 210. The atomized/volatile gas mixing tank 210 is coupled to the electrolysis device 100 by the first gas line 110, as shown in FIG. 3, which is used to accept the first gas 108 to mix an atomized medicine 212 in order to generate the inhalation-type pharmaceutical composition 214. The atomized/volatile gas generator 210 further comprises an oscillator 216, such as an ultrasonic oscillator. The oscillator 216 is adapted to atomize the medicinal liquid 220 in the atomized/volatile gas generator 210 in order to generate the atomized medicine 212. The medicinal liquid 220 can be a group comprising rivastigmine hydrogen tartrate, donepezil hydrochloride, galantamine hydrobromide, memantine hydrochloride, and any combination thereof. The above medicine for the treatment of Alzheimer's disease is well known to those skilled in the art, and hence will not be described in further detail.
In another embodiment of the present invention, the atomized/volatile gas generator 210 can accommodate between 40 c.c. and 100 c.c of medicinal liquid, which can be completely atomized within 60 min using the atomized/volatile gas generator 210. Therefore, the gas yield of the atomized medicine can be between about 0.67 cc/min to about 1.67 cc/min, and the gas yield controlled by the electrolysis tank 102 can be between about 2,000 cc/min to about 3,000 cc/min, wherein the gas generated from the electrolysis tank only has the gas mixture of hydrogen and oxygen (the volume ratio of hydrogen to oxygen is about 2:1), and thus the gas volume concentration of hydrogen in the inhalation-type pharmaceutical composition is between 66.61 and 66.65%. The heat is generated from the electrolysis tank when the electrolytic tank is conducted to electrolyze. The water in the electrolysis tank will then be evaporated by the heat generated from the electrolysis tank. Then the gas generated from the electrolysis tank not only has the gas mixture of hydrogen and oxygen but also has a small amount of water vapor, therefore the gas volume concentration of hydrogen in the inhalation-type pharmaceutical composition will be lower than 66.61%, for example the gas volume concentration of hydrogen in the inhalation-type pharmaceutical composition can be between 60 and 66.61%. Evidently, the small amount of water vapor can be reduced through cooling. Therefore, the inhalation-type pharmaceutical composition for the treatment of Alzheimer's disease can be made by mixing the gas mixture of hydrogen and oxygen with the atomized medicine. The gas volume concentration of hydrogen in the inhalation-type pharmaceutical composition is generally between 60% ̃66.61%.
In another embodiment of the present invention, the composition ratio of the first gas and the atomized medicine in the inhalation-type pharmaceutical composition separately are 35.33 ̃99.99% and 0.01 ̃64.67%, which are calculated according to the concentration percentage of the gas, but are not limited thereof. In practical application, the composition ratio of the first gas and the atomized medicine can be adjusted according to the patient's situation and is also administered daily through inhalation at least one to three times, where each session may be in the range of 30 to 60 minutes.
In another embodiment of the present invention, the composition ratio of the first gas, the atomized medicine and the second gas in the inhalation-type pharmaceutical composition separately are 33 ̃97%, 0.01 ̃64%, and 2 ̃66%, which are calculated according to the concentration percentage of the gas, but are not limited thereof. In practical application, the composition ratio of the first gas, the atomized medicine and the second gas can be adjusted according to the patient's situation and is also administered daily through inhalation at least one to three times, where each session may be in the range of 30 to 60 minutes.
According to the above embodiments of the present invention, the inhalation-type pharmaceutical composition of the present invention comprises hydrogen and the atomized medicine in order to form the inhalation-type pharmaceutical composition that is to be inhaled by a user (not shown). Studies have found that there is an instable oxygen species (O+), also known as free radicals, in the human body. The free radicals are usually created due to diseases, diet, environment and one's lifestyle, where the free radicals can be excreted in the form of water by reacting with the inhaled hydrogen. Using this method, the amount of free radicals in the human body can be reduced, thereby restoring the body condition from an acidic state to an alkaline state, which can achieve an anti-oxidation, anti-aging and beauty health effect, and even eliminating chronic diseases. In addition, according to clinical studies, the atomized medicinal liquid is 1-5 micro meters and is more easily absorbed by the human body than its non-atomized counterpart. That is to say, compared with its non-atomized counterpart, the atomized medicine can achieve the same therapeutic effect with a much lower dosage. Furthermore, the drug's side effects can be reduced due to the lower dosage of administered atomized medicine. The medicinal liquid may be the liquid mixture that is oral medicine dissolved in the water. Therefore, the inhalation-type pharmaceutical composition having hydrogen and the atomized medicine may provide an excellent therapeutic effect.
Compared to conventional technology, the present invention provides an inhalation-type pharmaceutical composition for the treatment of Alzheimer's disease and the preparation method thereof. The inhalation-type pharmaceutical composition of the present invention can provide the convenience of taking medicine and removing harmful radicals in the body of the patient through the use of hydrogen while also increases the absorption effect of the medicine for the patient by using an atomized medicine. At the same time, because the use of the small amount of the vaporized pharmaceutical liquid can indirectly reduce the side effects on the user.
With the examples and explanations mentioned above, the features and spirits of the invention are hopefully well described. More importantly, the present invention is not limited to the embodiment described herein. Those skilled in the art will readily observe that numerous modifications and alterations of the device may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the meets and bounds of the appended claims.
