Definitions
- the present invention relates to low dose nicotine dry powder compositions for inhalation.
- Nicotine is injected into the body through various methods, such as by smoking cigarettes such as cigarettes, cigars, pipes, etc., by using a method in which aerosol is generated by heating the aerosol-generating material in a cigarette, or by directly inhaling nicotine powder, etc. It is delivered.
- the method of directly inhaling nicotine powder uses a dry powder inhaler (DPI) to deliver it directly to the user's airway by inhaling the dry powder, and the dry powder improves diseases in addition to nicotine.
- DPI dry powder inhaler
- it is also used including various active ingredients (drugs).
- the conventional nicotine dry powder for inhalation has a nicotine content of 1 to 10% by weight, so it has the potential to cause coughing when inhaled, and the cough induced during inhalation causes discharge of the inhaled active ingredient, etc. There was a problem of not being able to obtain sufficient functionality.
- One purpose of the present invention is to solve the above problems, suppress coughing caused by high nicotine content when inhaling nicotine dry powder, and sufficiently and effectively perform the designed nicotine function through appropriate adjustment of nicotine powder and flavor powder.
- the object is to provide an obtainable nicotine dry powder composition for inhalation and a method for producing the same.
- a nicotine dry powder composition for inhalation comprising nicotine powder and flavor powder
- the nicotine powder contains nicotine or nicotine salt, amino acids, and excipients,
- the flavor powder includes flavoring agents and excipients
- a nicotine dry powder composition for inhalation characterized in that the nicotine content is less than 0.5% by weight based on the total dry powder composition.
- the nicotine dry powder composition for inhalation When using the nicotine dry powder composition for inhalation according to one aspect of the present invention, coughing is suppressed, discharge of the inhaled active ingredient is suppressed, and the user can sufficiently and effectively obtain the designed function of nicotine and active ingredient, You can maximize the satisfaction of nicotine, etc.
- FIG. 1 is a diagram showing the spray drying process and conditions according to an embodiment of the present invention.
- Figure 2 is a diagram showing the jet milling process and conditions according to an embodiment of the present invention.
- Figure 3 is a graph showing the evaluation results of the NGI (Next generation impactor) test, a standard device for evaluating pharmaceutical inhalants, when the nicotine content is 0.99% by weight, 0.74% by weight, and 0.5% by weight, respectively.

- the flavor powder includes flavoring agents and excipients
- a nicotine dry powder composition for inhalation characterized in that the nicotine content is less than 0.5% by weight based on the total dry powder composition.
- Nicotine powder according to an embodiment of the present invention is an element constituting a nicotine dry powder composition for inhalation and corresponds to a powder containing nicotine or a nicotine salt.
- the nicotine salt may exist in the form of a salt of nicotine and an organic acid
- the organic acid may correspond to lactic acid, tartaric acid, pyruvic acid, benzoic acid, citric acid, and/or salicylic acid, but is not limited thereto.
- the organic acid has the advantage of being a metabolite in vivo, being non-toxic and harmless to the human body, and being easily decomposed and excreted even when absorbed into the human body.

- the nicotine salt is preferably nicotine lactate.
- Nicotine powder may contain amino acids and excipients in addition to the nicotine or nicotine salt.
- the type of amino acid is not greatly limited, but may be one or more of leucine, lysine, valine, arginine, threonine, phenylalanine, glycine, and/or methionine, and preferably the amino acid may include leucine. .
- leucine when leucine is included as an amino acid, unlike in the case of other amino acids, leucine has hydrophobicity and is distributed to the outer shell of the powder when forming the powder, thereby improving the flowability of the final nicotine dry powder composition. Compliance can be improved.
- the content of amino acids included at this time is preferably 5% by weight or less based on the total dry powder.
- the amino acid content is preferably 5% by weight or less as described above, the particle size and particle size distribution of the final nicotine dry powder composition can be improved, and the leucine content is also subject to FDA approval.

- the excipient preferably contains mannitol, which has the advantage of being formulated through spray drying.
- the mannitol is water-soluble, stable in moisture before and after formulation, has no particularly negative sensory characteristics other than a slight sweetness, and has no special side effects, so it is particularly advantageous for use as a carrier material for delivering nicotine.
- Mannitol has the advantage that when absorbed into the bronchial tubes, it can bind with bronchial sputum (phlegm) and play a role in facilitating excretion.
- the nicotine dry powder composition for inhalation includes flavor powder as another component, and the flavor powder will be described in detail below.
- the flavor powder may be composed of a flavoring agent and an excipient, and the flavoring agent refers to a flavor commonly used in smoking articles, etc., for example, rosemary, eucalyptol, licorice, sucrose, fructose syrup, Isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, mint oil, mandarin oil, It may include, but is not limited to, catechin, grapefruit, caraway, cognac, jasmine, cocoayl, menthol, cinnamon, ylang-ylang, sage, spearmint, ginger, coriander, coffee, etc.
- the flavoring agent refers to a flavor commonly used in smoking articles, etc., for example, rosemary, eucalyptol, licorice, sucrose, fructose syrup, Isosweet, cocoa, lavender, cinnamon,
- the flavoring agent contains menthol.
- the flavor powder may also contain excipients, and the types of excipients include sugars and/or sugars including sucrose, trehalose, dextrose, glucose, maltose, etc., as described in detail previously. It may contain sugar alcohols including mannitol, sorbitol, galactitol, maltitol, xylitol, lactitol, etc. Among these, it is preferable to use mannitol as an excipient.
- the nicotine dry powder composition for inhalation may include nicotine powder and flavor powder in a weight ratio of 9:1 to 5:5, preferably in a weight ratio of 8:2 to 6:4. It may be included.
- the aerodynamic delivery characteristics of the powder can be adjusted.
- the particle size, particle distribution, and transfer characteristics of the powder are good, allowing the user to enjoy the functions of nicotine and flavor.
- everyone can be satisfied.
- the weight ratio of nicotine powder and flavor powder exceeds 9:1 (for example, 10:1, etc.)
- the sensation of hitting the upper bronchial tubes may be reduced
- the weight ratio of nicotine powder and flavor powder is 5.
- it is less than 5 for example, 4:6, etc.
- the particles tend to become larger, making it difficult for the flavor particles to attract and deliver the nicotine particles to the inside of the bronchial tubes.
- the nicotine content ultimately included in the nicotine dry powder composition for inhalation is less than 0.5%, and if the nicotine content is higher than this, the amount of nicotine provided may be reduced due to coughing. Compared to this, the use (inhalation) efficiency of inhaled nicotine may be reduced.
- the nicotine dry powder composition for inhalation may further include a cough suppressant component in addition to the nicotine powder and flavor powder described in detail above, and is not greatly limited to these cough suppressant components.
- a cough suppressant component in addition to the nicotine powder and flavor powder described in detail above, and is not greatly limited to these cough suppressant components.
