The materials, compounds, compositions, articles, and methods described herein may be understood more readily by reference to the following detailed description of specific aspects of the disclosed subject matter and the Examples included therein.
Also, throughout this specification, various publications are referenced. The disclosures of these publications in their entireties are hereby incorporated by reference into this application in order to more fully describe the state of the art to which the disclosed matter pertains. The references disclosed are also individually and specifically incorporated by reference herein for the material contained in them that is discussed in the sentence in which the reference is relied upon.
General Definitions
In this specification and in the claims that follow, reference will be made to a number of terms, which shall be defined to have the following meanings:
All percentages, ratios and proportions herein are by weight, unless otherwise specified. All temperatures are in degrees Celsius (° C.) unless otherwise specified.
The terms “a” and “an” are defined as one or more unless this disclosure explicitly requires otherwise.
Ranges may be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, another aspect includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another aspect. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint.
The terms “comprise” (and any form of comprise, such as “comprises” and “comprising”), “have” (and any form of have, such as “has” and “having”), “include” (and any form of include, such as “includes” and “including”) and “contain” (and any form of contain, such as “contains” and “containing”) are open-ended linking verbs. As a result, an apparatus that “comprises,” “has,” “includes” or “contains” one or more elements possesses those one or more elements, but is not limited to possessing only those elements. Likewise, a method that “comprises,” “has,” “includes” or “contains” one or more steps possesses those one or more steps, but is not limited to possessing only those one or more steps.
Any embodiment of any of the disclosed methods or compositions can consist of or consist essentially of—rather than comprise/include/contain/have—any of the described steps, elements, and/or features. Thus, in any of the claims, the term “consisting of” or “consisting essentially of” can be substituted for any of the open-ended linking verbs recited above, in order to change the scope of a given claim from what it would otherwise be using the open-ended linking verb.
The feature or features of one embodiment may be applied to other embodiments, even though not described or illustrated, unless expressly prohibited by this disclosure or the nature of the embodiments.
Any embodiment of any of the disclosed compounds or methods can consist of or consist essentially of—rather than comprise/include/contain/have—any of the described steps, elements, and/or features. Thus, in any of the claims, the term “consisting of” or “consisting essentially of” can be substituted for any of the open-ended linking verbs recited above, in order to change the scope of a given claim from what it would otherwise be using the open-ended linking verb.
For the purposes of the present disclosure the terms “sublingual” and “buccal” are used interchangeably. The definition of “sublingual” is administration of a drug under the tongue to be absorbed by the tissue therein. The definition of “buccal” is to administer a drug by placing it between your cheek and gum. For the purposes to the present disclosure the user can either place the disclosed compositions under the tongue of between the check and gum, whichever mode of delivery is more convenient. Therefore, the disclose compositions can be absorbed in any manner chosen by the user.
The feature or features of one embodiment may be applied to other embodiments, even though not described or illustrated, unless expressly prohibited by this disclosure or the nature of the embodiments.
A smokeless oral nicotine product can be provided to the user in a portioned or a non-portioned format. Portioned smokeless oral nicotine products can reduce or eliminate the handling of the tobacco by the user, which can offer significant advantages in terms of better hygiene, convenience and/or ease of use.

Nicotine Compounds
Disclosed herein are two sources of nicotine: naturally derived and synthetic. The two forms of nicotine are not combined or otherwise admixed with one another in any of the compositions disclosed herein. The disclosed salts can be formed from either the naturally derived or the synthetic nicotine. The word “nicotine” is used herein to refer to both naturally derived or synthetic nicotine unless otherwise designated as naturally occurring or synthetic nicotine.
The disclosed nicotine compounds are chosen from nicotine, pharmacologically acceptable salts of nicotine, a nicotine complexes, and polymer resins of containing nicotine. Non-limiting examples of nicotine salts includes nicotine benzoate, nicotine lactate, nicotine malate, nicotine ditartrate, nicotine salicylate, nicotine citrate and nicotine levulinate. Non-limiting examples of nicotine in combination with a resin includes nicotine polacrilex and nicotine resinate.
In one non-limiting example the nicotine salt is nicotine benzoate. In another non-limiting example the nicotine salt is nicotine lactate. In a further non-limiting example the nicotine salt is nicotine malate. In a yet further non-limiting example the nicotine salt is nicotine ditartrate. In a still yet further non-limiting example the nicotine salt is nicotine salicylate. In a yet another non-limiting example the nicotine salt is nicotine citrate. In a still yet another non-limiting example the nicotine salt is nicotine levulinate.
Nicotine can be synthesized by the procedure outlined herein below in Scheme I. Synthetic details can be found in Del Castillo E et al., “Enantioselective Synthesis of Nicotine via an Iodine-Mediated Hoffmann-Loffler Reaction,” Org. Lett. 2019, 21, 705-708.

Carriers
In one aspect the disclosed carriers are polysaccharides. Non-limiting examples of poly saccharide carriers include inulin, galactogen, cellulose, chitin, pectin, psyllium, guar, hemicellulose, potato starch, and partially hydrolyzed polysaccharides. In another aspect the carriers are sugar alcohols, for example, sorbitol, erythritol, xylitol, lactitol, maltitol, mannitol, hydrogenated starch hydrolysates, isomaltose, or any combination thereof In a further aspect carrier component is based on a native or chemically modified agar, alginates, carrageenan gum, cellulose, chitosan, chitin, cyclodextrin, dextran, gellan gum, glycogen, glycosaminoglycan, gum karaya, inulin, pectin, polydextrose, xanthan gum, or any other starches, gums or other polysaccharide, including functionalized derivatives, dextrinized, hydrolyzed, oxidized, alkylated, hydroxyalkylated, acetylated, fractionated, and physically modified starches and mixtures thereof In some embodiments glycerin and/or propylene glycol can be added as a carrier.
In one aspect the carrier can serve as a bulking agent. In one embodiment, microcrystalline cellulose is utilized as a carrier in the base compositions and as a bulking agent in the pouches disclosed herein below. In another embodiment, two or more carriers can be combined, for example, microcrystalline cellulose and inulin. This combination can be utilized in both the base composition, as well as in the pouches. As it relates to the disclosed pouches, dextrin is added as a bulking agent, however, dextrin can also serve as carrier for any flavors that the formulator wishes to add. For example, ethylvanillin is a compound which provides vanilla flavoring. Ethylvanillin can be compounded with dextrin, microcrystalline cellulose or inulin and then admixed with the bulking agents or other carriers.
In one aspect of the one or more carriers, one of the carriers is water soluble while others are not. This allows the formulator to control the release of the active base when the active base is delivered by way of a non-water soluble, but water permeable pouch as described herein below. This combining of carriers allows the delivery of nicotine either via a nicotine salt or by way of a polymer supported nicotine, for example, polacrilex.
The disclosed compositions can comprise from about 80% to about 95% by weight of one or more carriers. In one embodiment the disclosed compositions can comprise from about 80% to about 90% by weight of one or more carriers. In another embodiment the disclosed compositions can comprise from about 85% to about 95% by weight of one or more carriers. In a further embodiment the disclosed compositions can comprise from about 85% to about 90% by weight of one or more carriers.

The amount of each ingredient varies depending upon the formulator's choice of the ratio of the nicotine-containing ingredient and sunflower oil, i.e., the ratio of nicotine-containing ingredient to sunflower oil can be, as disclosed herein above, from about 1:1 to about 1:3. The choice of ratio will also dictate the relative amounts of adjunct ingredients that are added. With stirring, the nicotine-containing ingredient sunflower oil admixture is then slowly heated to from about 50° C. to about 75° C., again predicated on the ratio of ingredients and the choice of excipients.
At this point antioxidants, as well as other adjunct ingredients can be optionally added to the nicotine-containing compound/sunflower oil admixture during heating. The amount and ratio of any antioxidants added to the admixture varies depending upon the formulator's choice. In one non-limiting embodiment, the amount of antioxidant is from about 0.01% to about 0.10% by weight of the admixture.
Following the optional addition of an antioxidant and/or other adjunct ingredients, the resulting admixture is then slowly added to a dry particulate substrate with sufficient mixing to form a homogenous dispersion. The quantity of the admixture that is added to the substrate is from about 5% to about 60% by weight. The final dispersion is then dehydrated by which ever means chosen by the formulator, for example, oven drying, lyophilization, convection drying, microwave radiation, etc. In one non-limiting embodiment, the dispersion is dried from about 45 to about 135 minutes. Depending upon many factors including the type of adjunct ingredients and the ratio of the nicotine-containing compound to sunflower oil, the time can be shortened or lengthened.
At this point an alkalizing agent is incorporated. In one non-limiting example, sodium bicarbonate is used as the alkalizing agent. The amount of alkalizing agent is predicated on the amounts of other ingredients and the choice of substrate. In one non-limiting embodiment the composition can comprise from about 1% to about 25% by weight of the alkalizing agent.
After homogenizing the alkalizing agent into the homogeneous admixture now formed, other adjunct ingredients can be added. Non-limiting examples include bulking agents which provide a mouthfeel that is compatible with the pouches, thereby providing the user with a feeling of “substance” inside the pouch. Bulking agents include microcrystalline cellulose and inulin. In addition, sweeteners, for example, maltitol, and/or flavoring compounds are added to provide different oral sensations.
The resulting composition can then be further compounded with other adjunct ingredients, at levels that vary depending upon the formulator's choice, such as bulking agents (e.g., microcrystalline cellulose), high potency sweeteners (e.g., maltitol) and/or flavoring compounds, and ultimately rendered in various different oral or intraoral form factors.
In one non-limiting example, nicotine benzoate (15 g) and sunflower oil (45 g) are combined in a stainless-steel reaction vessel with efficient stirring and heated to 50° C. until homogeneous. The nicotine benzoate sunflower oil admixture is then slowly metered into inulin (500 g) as a dry particulate substrate compound while mixing until homogeneously dispersed. Sodium bicarbonate (20 g) is added while mixing until homogenously dispersed. The admixture is then placed in a convection airflow dehydration chamber for 90 minutes to remove remaining moisture and effect a molecular association between the nicotine and the sunflower oil infused dry particulate. The resulting composition is then combined with microcrystalline cellulose (200 g), maltitol (175 g) and spearmint flavoring (100 g) and then charged to unit dose oral pouches.
Pouches
The properties of the pouch can influence the release of the nicotine, nicotine salt, or nicotine in combination with a resin from the pouch composition and thereby possibly influence the rate of uptake by the user. The disclosed pouches comprise water insoluble fiber which allows moisture, typically the user's saliva, to enter the pouch and solubilize the water-soluble components.
Disclosed herein are water-insoluble pouches which can comprise insoluble fiber, for example, wheat fibers, oat fibers, pea fibers, rice fiber, maize fibers, oat fibers, tomato fibers, barley fibers, rye fibers, sugar beet fibers, buckwheat fibers, potato fibers, cellulose fibers, apple fibers, cocoa fibers, cellulose fiber, powdered cellulose, bamboo fibers, bran fibers or combinations thereof.
In one embodiment the disclosed pouches comprise cellulose prepared by processing alpha-cellulose obtained as a pulp from strains of fibrous plant materials, such as wood pulp. In a further embodiment the pouches can comprise wheat fibers, oat fibers, or combinations thereof. The following are non-limiting examples of plant fibers Vitacel WF 600™, Vitacel HF 600™, Vitacel P95™, Vitacel WF 200™, Vitacel LOO™, Vitacel Erbsenfaser EF 150™, Vitacel bamboo fiberbaf 90™Vitacel HF 600™, Vitacel Cellulose L700G™, Vitacel PF200™, Vitacel potatofiber KF200™, Vitacel bamboo fiberhaf BAF40™, Vitacel Haferfaser/oat fiber HF-401-30™, Vitacel L 00™, Vitacel Cellulose L700G™, Vitacel LC1000™, Vitacel L60020™, Vitacel L600™ or combination thereof.
In formulating pouches containing various amounts of the base nicotine delivery composition it is one embodiment of the present disclosure that the amount of water-insoluble fiber can be reduced without compromising the mouthfeel during use. It is important that the pouch material does not cause swelling in use because this fact can counteract the dissolution of the water-soluble component, thereby preventing the user from experiencing any decrease in pouch content during use.
In addition, the pouch composition can also provide for a desirable mouthfeel such as a soft and/or sticky texture. The desirable texture and mouthfeel can be obtained while still being able to store manufactured pouches together in abutment, for example, in cans and the like without sticking or clumping together to result in ruptures of the pouches when being removed. The desirable mouthfeel can in some embodiments also comprise a tingling sensation reminiscent of tobacco pouches, but without many of the undesirable effects associated therewith, for example, discoloring of tissue.
In one aspect of the disclosed kits, the kits comprise an active base composition and a pouch for delivery of nicotine sublingually to the user.
The disclosed kits can comprise either naturally occurring nicotine or synthetic nicotine, the choice of which is left to the formulator. The kits comprise a water-permeable pouch, into which an active base composition and a delivery system is added. The disclosed pouches comprise:

B) from about 80% to about 95% by weight of a delivery system wherein the delivery control system contains one or more delivery control agents, carriers, solubilizers or mixtures thereof.
In one embodiment of this aspect, the pouches comprise:
A) from about 70 mg to about 510 mg of an active base composition, comprising:
B) from about 350 mg to about 1500 mg of one or more carriers; and

As demonstrated by the following data and
The disclosed animal studies were conducted utilizing the disclosed compositions. Table I summarizes the Study design. Male Beagle dogs from Marshall Bioresources were utilized for this study. Animals were identified by ear tattoo and cage label. The study was not blinded. The animals were healthy at the start of the study. Body weights were recorded at each dosing time point. General health observations were recorded at each dosing and sample collection time point for the duration of the study.
Dosing
Nicotine, 4 mg per pouch, was administered via buccal administration. Animals were anesthetized with propofol at a dose of 6 mg/kg, animals were then intubated and maintained in an anesthetic state using isoflurane at 1-5% and 2 L of oxygen flow. The pouch with test article was placed in the buccal space, rinsed with a small volume of water (0.5-1 mL). Every 5 minutes after placing the pouch the test article test article in the buccal space, the isoflurane mask was removed and the pouch gently squeezed. Special attention was taken to ensure saliva did not leak from the mouth. Following 30 minutes, the pouch test article was removed from the buccal space and the animal allowed to recover from anesthesia. All pouches were retained following dosing. Each pouch was placed in individual conical tube with the animal ID and pouch identification.

Sample Collection, Preparation and Storage
Each blood sample (approx. 2000 μL) was collected from the jugular vein in a K2ETDA collection tube and gently inverted several time to mix. The samples were kept on ice until centrifugation at 4° C. for 5 minutes at 3,000×g. Approximately 1000 μL plasma was separated by centrifugation. The resulting plasma samples were stored at -80 C until bioanalysis was conducted.
Quantitative Plasma Sample Analysis
Plasma samples were extracted by protein precipitation and analyzed using LC-MS/MS. Individual and Mean plasma concentrations and resulting pharmacokinetic parameters for nicotine are shown in Tables 4-7. All data are expressed as ng/mL of nicotine. Samples that were below the limit of quantification (1.0 ng/mL in plasma) were excluded from the calculation of mean values. Mean concentrations versus time data are plotted in
Pharmacokinetic parameters were calculated from the time course of the plasma concentration. Pharmacokinetic parameters were determined with Phoenix WinNonlin (v8.0) software using a noncompartmental model. The maximum plasma concentration (Cmax) and the time to reach maximum plasma concentration (tmax) after dosing were observed from the data. The area under the time concentration curve (AUC) was calculated using the linear trapezoidal rule with calculation to the last quantifiable data point (AUCO-last), and with extrapolation to infinity (AUC∞) if applicable. Plasma half-life (t1/2) was calculated from 0.693/slope of the terminal elimination phase. Mean residence time, MRT, was calculated by dividing the area under the moment curve (AUMC) by the AUC. Any samples below the limit of quantitation (1.0 ng/mL plasma) were not used in the calculation of mean values
