In the context of the present invention, the singular form of a word may include the plural, and vice versa, unless the context clearly dictates otherwise. Thus, the references “a,” “an” and “the” are generally inclusive of the plurals of the respective terms. For example, reference to “an ingredient” or “a method” may include a plurality of such “ingredients” or “methods.”
Similarly, the words “comprise,” “comprises,” and “comprising” are to be interpreted inclusively rather than exclusively. Embodiments provided by the present disclosure may lack any element that is not specifically disclosed herein. Thus, a disclosure of an embodiment defined using the term “comprising” is also a disclosure of embodiments “consisting essentially of” and “consisting of the disclosed components”. Thus, the term “comprising” is generally to be interpreted as specifying the presence of the stated parts, steps, features, or components, but does not exclude the presence of one or more additional parts, steps, features, or components. For example, a composition comprising a chemical compound may thus comprise additional chemical compounds.
Generally, compositions as disclosed herein, in particular topical compositions and/or compositions for oral consumption may comprise one or more pharmaceutically acceptable carrier(s), excipient(s), stabilizer(s) or the like.
Where used herein, terms like “for example”, “e.g.” or “such as”, particularly when followed by a listing of terms, is merely exemplary and illustrative, and should not be deemed to be exclusive or comprehensive. Any embodiment disclosed herein may be combined with any other embodiment disclosed herein.
Unless expressed otherwise, all percentages expressed herein are by weight of the total weight of the composition. Thus, unless indicated otherwise, “%” indicates “% weight/weight (w/w)”, also called “weight %” or “% by weight”.
In the context of the present invention, the terms “about”, “around”, “approximately” or the symbol “˜” can be used interchangeably, and are meant to comprise variations and/or uncertainties generally accepted in the field, e.g. comprising analytical errors and the like. Thus “about” may also indicate measuring uncertainty commonly experienced in the art, which can 10 be in the order of magnitude of e.g. +/−1, 2, 5, 10, or even 20 percent (%). Furthermore, “about” may be understood to refer to numbers in a range of numerals, for example the range of +/−20, +/−15, +/−10, +/−5, +/−2, +/−1, +/−0.5, +/−0.1% of the referenced number. Moreover, all numerical ranges herein should be understood to include all integers, whole or fractions, within the range.
As used herein, the term “in some embodiments” is meant to comprise “in one embodiment”, “in some embodiments”, and “in one or more embodiments”.
In the context of the present invention, the terms “subject” or “patient” can be used interchangeably, and are meant to comprise a human, animal and/or mammal. In particular, a human subject can e.g. be selected from one or more of: female, male, senior, adult, adolescent, child, or infant. An animal subject can e.g. be selected from pet, husbandry, mammal, reptile, bird, and/or animal in a zoo.
In the context of the present invention, the term “treatment” is meant as an act aiming at alleviating, lessen, improving and/or curing any symptom(s), condition(s), or disease(s) in a subject. The effect or efficiency of a treatment can be assessed by a control, e.g. no treatment, treatment with a known composition, or treatment with a placebo. Generally, a “treatment” in the present context comprises administration of a suitable amount of a composition to a subject. Compositions of the present invention are preferably administered intra-nasally, such as by a nose spray using a nasal pump spray device used in the treatment of nasal congestion, such as Navision® or Otrivin® comprising xylometazoline, such as xylometazoline hydrochloride.
Alternatively, the composition can be administered inside the nostril(s) by other means, such as applying a suitable amount with e.g. a finger or applicator, and/or by “sniffing” or “snorting”.
In the context of the present invention, the terms “intra-nasal”, “intranasal” and simply “nasal” can be used interchangeably. This applies as well for “intra-nasally”, “intranasally” and simply “nasally”.
A “sleep disorder” or “somnipathy” can be described as a disorder of the sleep patterns of a subject. Sleep disorders are common in both children and adults. Disruptions in sleep can be caused by a variety of issues, including teeth grinding (bruxism) and night terrors. Commonly, when a subject suffers from difficulty falling asleep and/or staying asleep with no obvious cause, it is referred to as insomnia. Sleep disorders can e.g. be classified into dyssomnias, parasomnias, circadian rhythm sleep disorders involving the timing of sleep, and other disorders including ones caused by medical or psychological conditions.
The most common sleep disorder is insomnia. Other disorders are sleep apnoea, narcolepsy and hypersomnia (excessive sleepiness at inappropriate times), sleeping sickness (disruption of sleep cycle due to infection), sleepwalking, and night terrors.
The risk of developing sleep disorders in the elderly is especially increased for sleep disordered breathing, periodic limb movements, restless legs syndrome, REM sleep behaviour disorders, insomnia and circadian rhythm disturbances.
Nasal sprays are used to deliver medications locally in the nasal cavities or systemically. They are used locally for conditions such as nasal congestion and allergic rhinitis. In some situations, the nasal delivery route is preferred for systemic therapy because it provides an agreeable alternative to injection or pills. Substances can be assimilated extremely quickly and directly through the nose. Many pharmaceutical drugs exist as nasal sprays for systemic administration (e.g. sedative-analgesics, treatments for migraine, osteoporosis and nausea). Other applications include hormone replacement therapy, treatment of Alzheimer's disease and Parkinson's disease. Nasal sprays are often seen as a more efficient way of transporting drugs with potential use in crossing the blood-brain barrier.
Apart from treatment of one or more sleep disorders, the present compositions are also believed to be suitable to provide relaxation of a subject, in particular nervousness or even fear, in particular irrational fear. Examples may comprise user situations in e.g. public transport, passengers in aircraft, train, bus, or car, such as transport situations, where the subject would like to relax and/or sleep, but is hindered to do so because of anxiety. Further conditions and/or examples may comprise jet lag, anxiety, and/or difficulties in falling asleep under unusual circumstances, e.g. when travelling, e.g. not sleeping at home, e.g. during transport in a bus, car, train, aeroplane, ship, hotel, pension, prison, or in a hospital, hospice, or the like, as well as during military service or the like. In some embodiments, the present composition provides a positive effect and/or treatment in a condition related to Parkinson, multiple sclerosis (MS), muscle spasmed, anxiety, depression, Alzheimer, epilepsy, pain relief, and/or neuroprotective effects.
In a first aspect, the present invention concerns a composition comprising by weight: 5-30% hemp oil; 0.1-5.0% cannabidiol (CBD) and/or cannabinol (CBN); 0.01-1.0% lavender oil; 30-95% (or up to 100%) sesame oil; and 0.1-5.0% vitamin E and/or Tocopherol equivalents.
The composition can be formulated for nasal application, e.g. as nasal spray.
“Hemp seed oil” or “hemp oil” is obtained by pressing hemp seeds. It is rich in healthful oils and fatty acids, is popular as a remedy for a range of conditions including skin issues and stress. It may also contain properties that contribute to reduced risks of illnesses like Alzheimer's disease and cardiovascular disease. Hemp oil may also reduce inflammation in the body. Hemp oil contains large amounts of omega-6 and omega-3 fats, and all nine essential amino acids. Hemp seeds also contain the following compounds: Vitamin C, Calcium, Iron, Omega-3 fatty acids, Gamma linolenic acid, Arginine, Magnesium, and B vitamins. Hemp oil may comprise further compounds, there among cannabinoids, but only in very low or trace amounts.
“Cannabidiol” or “CBD”, CAS no. 3956-29-1, is a commonly cannabinoid used to address a variety of medical conditions, including insomnia. In contrast to e.g. tetrahydrocarbinol (THC) and tetrahydrocannabivarin (THCV), CBD is considered to be one of the many non-psychoactive cannabinoids found in Cannabis.
“Cannabinol” or “CBN”, CAS no 521-35-7, is a cannabinoid that has been shown to help effectively as a sleep aid or sedative, to regulate the immune system and works to relieve the pain and inflammation caused by several conditions, including insomnia, arthritis and Crohn's disease. It is believed to be mildly psychoactive, and only found in trace amounts in Cannabis.
“Lavender essential oil” or “lavender oil” is used e.g. in aromatherapy. Commonly, lavender oil is produced by steam distillation of Lavandula angustifolia flowers. The oil promotes relaxation and is believed to treat anxiety, fungal infections, allergies, depression, insomnia, eczema, nausea, and menstrual cramps.
“Sesame oil” is an edible oil provided by pressing sesame seeds. Sesame oil can also be used for a variety of treatments and ailments. Sesame oil is believed to possess antifungal, antiviral, as well as anti-inflammatory properties. Furthermore, it contains antioxidants such as sesamol and sesaminol.
“Vitamin E” is a group of eight fat soluble compounds that include four tocopherols and four tocotrienols. Both the tocopherols and tocotrienols occur in α-, β-, γ-, and δ-forms, as determined by the number and position of methyl groups on the chromanol ring. Vitamin E is the major lipid-soluble antioxidant in the cell antioxidant defense system and is exclusively obtained from the diet. Vitamin E has health promoting properties that are attributed to its antioxidant action and its ability to stabilize cell membrane and promote restoration of the skin barrier function. Commonly, vitamin E activity of the different vitamin E isomers is expressed in “α-tocopherol equivalents”, or simply “tocopherol equivalents” (“TE”) herein. One TE is the activity of 1 mg RRR-α-tocopherol (d-α-tocopherol). According to the Food and Agriculture Organisation of the United Nations, e.g. β-tocopherol should be multiplied by 0.5, γ-gamma-tocopherol by 0.1, and a-tocotrienol by 0.3.
In some embodiments, the composition comprises 5-30%, 10-20%, or ˜16% hemp oil.
In some embodiments, the composition comprises 0.1-5.0%, 0.2-2.0%, or ˜0.4% CBD.
In some embodiments, the composition comprises 0.1-5.0%, 0.2-2.0%, or ˜0.8% CBN.
In some embodiments, the composition comprises 0.01-1.0%, 0.02-0.5%, or ˜0.03% lavender oil.
In some embodiments, the composition comprises 30-95%, 50-90%, or ˜82% sesame oil.
In some embodiments, the composition comprises 0.1-5.0%, 0.2-1.0%, or ˜0.55% vitamin E and/or Tocopherol equivalents).
Thus, in some embodiments a composition is provided comprising by weight:
Such compositions comprising CBD, CBN, or CBD and CBN can be, or are formulated for nasal application, such as for administering a suitable, preferably defined amount by appropriate means, such as by spraying, e.g. by the use of a nasal spray bottle. Generally, the composition will often be called “nasal spray composition”, or simply “nasal composition” herein; both terms can be used interchangeably.
In some embodiments, the nasal composition comprises both CBN and CBD. Surprisingly and unexpectedly, compositions comprising more CBN than CBD showed a better effect. Thus, in some embodiments, the CBN:CBD ratio by weight is greater than 1.
In some embodiments, CBN:CBD ratio can be in the range of 10:1-5:1; 5:1-4:1; 4:1-3:1; 3:1-2:1; or 2:1-1.1. In some embodiments, the CBN:CBD ratio is around 10:1, ˜9:1, ˜8:1, ˜7:1, ˜6:1, ˜5:1, ˜4:1, ˜3.5:1, ˜3:1, ˜2.5:1, ˜2:1, ˜1.5:1, ˜1.25:1, ˜1.2:1, ˜1.15:1 or ˜1.1:1. In some embodiments, the CBN:CBD ratio is in the range of 2.5:1- 1.5:1, 2.25:1.75, 2.2-1.8, 2.1-1.9, or around 2:1. In some embodiments, the CBN:CBD ratio is in the range of 5:1 to 1:1, 4:1 to 1.1:1, 3:1 to 1.1:1, 2.5:1 to 1.1:1, 2.2:1 to 1.1., 2 to 1.1, 1.75:1, 1.5:1, 1.25: 1, or 1.15 to 1. In some embodiments, the ratio of CBN to CBD of around 3:1-1.5:1, 2.5:1.75, 2.2-1.8, 2.1:1:9, or around 2:1.
Ratios of e.g. 3:1-1.5 are believed to provide a good balance of the two cannabinoids in terms of treatment of e.g. sleep disorders, and/or one or more of the other conditions disclosed herein.
In some embodiments, the nasal composition may comprise one or more further cannabinoid(s), such as one or more psychoactive and/or one or more non-psychoactive cannabinoid(s) in a physiologically active amount. Such a further cannabinoid may e.g. be selected from one or more of: THC (tetrahydrocannabinol), THCA (tetrahydrocannabinolic acid), CBDA (cannabidiolic acid), CBG (cannabigerol), CBC (cannabichromene), CBL (cannabicyclol), CBV (cannabivarin), THCV (tetrahydrocannabivarin), THCP (tetrahydrocannabiphorol), CBDV (cannabidivarin), CBCV (cannabichromevarin), CBGV (cannabigerovarin), CBGM (cannabigerol monomethyl ether), CBE (cannabielsoin), and CBT (cannabicitran), including any combination(s) thereof. In some embodiments, one or more cannabinoids are present in non-physiologically significant amounts, such as impurities in one or more of: hemp oil, CBN, and or CBD. Commonly, an impurity is present in less than 1.5, 1.0, 0.5, 0.2, or 0.1% of said one or more further cannabinoid by with respect to either: total composition, hemp oil, CBN, or CBD.
In some embodiments, a composition may thus comprise 0.1-5.0% CBN and/or CBD, wherein the composition, CBN, CBD, and/or hemp oil (x) does not comprise, (y) does not comprise in a physiologically active amount, and/or (z) comprises less than 2.0, 1.5, 1.0, 0.5, 0.2, or 0.1% (w/w) of one or more further cannabinoid(s), such as a one or more cannabinoids selected from THC, THCA, CBDA, CBG, CBC, CBL, CBV, THCV, THCP, CBDV, CBCV, CBGV, CBGM, CBE, and CBT.
Also, a low content of one or more of CBDV, CBDA, CBG, THC and/or THCV can be indicative of a CBD and/or CBN of sufficient purity for compositions of the present invention.
Suitable hemp oil(s), CBD, and/or CBN with sufficient purity can e.g. be sourced from www.enecta.com.
In some embodiments, CBD is “crystalline” or “pure” CBD, such as CBD in powder-form, with a purity of at least 98%, and comprising less than 1.5% (w/w) of CBDV, CBG, and/or CBN, and less than 0.05% THC.
In some embodiments, CBN is “crystalline” or “pure” CBN, such as CBN in powder-form, with a purity of at least 98%, and comprising less than 1.5% (w/w) of CBDV, CBG, and/or CBD, and less than 0.05% THC.
In some embodiments, the composition and/or hemp oil comprises ≤0.2% or ≤0.05% CBDV by weight. Generally, a low content of CBDV and/or other cannabinoids is desirable.

Concerning the triglyceride composition, in some embodiments a refined sesame oil comprises (by weight): LLL 7-19% LLL, 13-30% OLL, 5-9% PLL, 12-23% OOL, 6-14% POL, 5-16% OOO, 2-8% SOL, and 2-10% POO. The fatty acid radicals are designated as linoleic (L), oleic (O), palmitic (P), and stearic (S). The abbreviations for triglycerides used are: trilinolein (LLL), 1,2-dilinoleoyl-3-oleoyl-rac-glycerol (OLL), 1,2-dilinoleoyl-3-palmitoyl-rac-glycerol (PLL), 1,2-dioleoyl-3-linoleoyl-rac-glycerol (OOL), 1-palmitoyl-2-oleoyl-3-linoleoyl-rac-glycerol (POL), triolein (OOO), 1-linoleoyl-2-oleoyl-3-stearoyl-rac-glycerol (SOL), and 1,2-dioleoyl-3-palmitoyl-rac-glycerol (POO). Suitable sesame oils are e.g. available from www.oelmuehle-hartmann.de.
In some embodiments, the hemp-, lavender- and sesame oil are as specified above. The use of such compositions is believed to provide a product with satisfying properties in the context of the present invention, i.e. when provided in appropriate amounts, such as specified herein.
In some embodiments, suitable compositions may also be characterized by one or more, or all of the following features: (a) the concentration of CBD is lower than CBN (e.g. a ratio around 1:2); (b) concentration of CBD dissolved in hemp oil 1-10% or 2-5% *; (c) concentration of CBN dissolved in hemp oil: 2-20%, or 4-10%; (d) absence of other cannabinoids, in particular THC or other psychoactive components in physiologically active amounts; (d) absence of saline and/or alcohol.
In some embodiments, CBD and/or CBN can be dissolved in one or more of sesame-, hemp-, and lavender oil, thus not only in hemp oil.
Generally, non-hallucinogenic cannabinoids are preferred in order to avoid undesired side-effects upon use or treatment with composition(s) comprising such compounds, in particular when they are present in physiologically active amounts.
Further suitable concentrations and/or concentration ranges may be disclosed herein.
Concerning the CBD used in the preparation or formulation of a CBD-comprising composition, in some embodiments, the CBD used in the provision of the composition is crystalline. In some embodiments, the CBD is “type A CBD”. Often, the use and/or presence of “type A CBD” is preferred in contrast to “type B CBD”.
In some embodiments, the CBD used for providing a composition as disclosed above is characterized by certain features, such as the crystal structure, type and/or conformation. It has been observed by the inventors, see e.g. Example 10, that CBD with a needle-like crystal structure (=crystal structure A; see
In some embodiments, the CBD possesses, when crystalline, or is capable of forming a needle-like crystal structure. In some embodiments, CBD of crystal structure A (or capable of forming needle-like crystals) is at least 1.5, 2, 3, 4, 5, 7.5, 10, 15 or 20 times more potent on a weight/weight basis than CBD of crystal structure B (or capable of forming cluster/bunch-like crystals).
CBD of crystal structure A, or CBD capable of forming needle-like crystals, is also called “type A CBD” herein, while CBD of crystal structure B, or CBD capable of forming “bunch-like or “cluster-like” crystals is called “type B CBD”. In some embodiments, the CBD is “type A CBD”. Often, “type A CBD” is preferred in contrast to “type B CBD”.
It can be speculated, if the CBD needs to be in an active form, such one or more specific conformation(s) in order to be active upon administration to a subject, such as in a topical formulation. Lack of activity or potency can also be caused by a lower uptake rate and/or difficulties in passing through the skin.
Without wanting to be bound by any theory, it is believed that the difference in crystal structure may be caused by a different molecular structure, such as a different conformation. This could e.g. be due to a failure of the subject's body to recognize the “wrong” CBD conformation or the like. It is conceivable that the differences in CBD crystal structure are caused by a different extraction process. In particular, the CBD disclosed in
Generally, crystalline CBD can be provided by methods and techniques known in the art, such as by methods disclosed in U.S. Pat. No. 10,413,845 and/or U.S. Pat. No. 10,414,709.
In short, crystalline CBD can be provided from hemp or Cannabis (Cannabis sativa) by a method consisting essentially of:
Thus, in some embodiments, the CBD crystals used in the formulation and/or provision of the topical composition are needle-like crystals, such as crystals shown in
In some embodiments, the CBD crystals used in the provision and/or formulation of the topical composition are not provided by an extraction method comprising critical CO2 extraction.
In some embodiments, the CBD crystals used in the provision and/or formulation of the topical composition are provided by a method comprising extraction with a C3-C4 alcohol, such as isopropanol, and one or more crystallisations steps with a C6-C8 alkane, such as heptane. In some embodiments, the C3-C4 alcohol is isopropanol. In some embodiments, the C6-C8 alkane is heptane. In some embodiments, the C3-C4 alcohol is isopropanol, and the C6-C8 alkane is heptane. This combination is believed to provide CBD crystals of satisfactory quality, such as absence or reduction in inhibitors and/or the desired conformation of the CBD.
In some embodiments, a suitable CBD composition or product can be obtained when the CBD crystals are provided by a method comprising CO2 extraction, in particular critical CO2 extraction and one or more crystallisations steps with a C6-C8 alkane, such as heptane.
As seen in Table 1, it can be seen that the Cannabinoid profile of type A and type B CBD can be rather similar.
It is, however, also conceivable that the differences in crystal structure, can relate to and be caused by different extraction processes. Different crystal structures can also be indicative of different concentrations of “CBD inhibitors”, and/or different concentrations of “CBD enhancers”. In some embodiments, terpenes, such as naturally occurring terpenes, in particular terpenes found in plants, such as in Cannabis sativa, act as CBD inhibitors, which is not desirable.
Thus, in some embodiments, CBD of crystal structure B alias “type B CBD” can be converted to CBD of crystal structure A alias “type A CBD” (and/or CBD capable of forming crystal structure A) by an organic extraction step and/or recrystallisation step. In such embodiments, it is conceivable that the change in crystal structure is related to the presence of inhibitors that are reduced significantly in the additional extraction and/or crystallization step(s). Alternatively, the organic extraction step may provide a change in conformation of the CBD, rendering it more active again. In some embodiments, recrystallization with heptane can change the B-type CBD into A-type CBD.
In some embodiments, CBD of crystal structure B has been provided by critical CO2 extraction, such as CBD crystals provided by www.pharma-hemp.com and/or following a similar extraction protocol as said manufacturer.
In some embodiments, presence of terpenes and/or terpenoids, in particular Cannabis sativa terpenes or in a CBD-comprising topical composition as disclosed herein, provides one or more undesirable effect(s), such as one or more of: reduced efficiency or potency, inability or reduced ability to recognize the CBD, need for a higher CBD formulation for obtaining similar effect, increase in non-CBD cannabinoids in the formulation. In some embodiments, said composition comprises 0.0001% or less, 0.001% or less, 0.01% or less, or 0.1% or less terpenes, in particular Cannabis sativa terpenes, by weight.
In some embodiments, the crystalline CBD does not comprise significant amounts of terpenes, such as less than 0.1, less than 0.05, less than 0.02, less than 0.01, less than 0.005, less than 0.002, less than 0.001% terpenes by weight.
It is also conceivable that other plant components, such as terpenoids can act as inhibitors. In some embodiments the presence of terpenoids, such as Cannabis sativa terpenoids can be undesirable. In some embodiments, the crystalline CBD does not comprise significant amounts of terpenoids, such as less than 0.1, less than 0.05, less than 0.02, less than 0.01, less than 0.005, less than 0.002, less than 0.001% terpenoids by weight.

In short, crystalline CBD can be provided from hemp or Cannabis (Cannabis sativa) by a method consisting essentially of:
Extracting hemp or Cannabis with a solvent selected from the group consisting of propanol, isopropanol, butanol, pentanol, hexanol, heptanol, and octanol to produce an extract consisting essentially of an extracted hemp or Cannabis consisting essentially of tetrahydrocannabinol, a terpene, or cannabidiol;
Evaporating the solvent portion of the extract to generate a substantially solvent-free extract comprising CBD;
Distilling the substantially solvent-free extract to isolate the CBD, and
Crystallizing the distilled, isolated CBD to produce a crystallized, isolated CBD.
Often, the crystallized, isolated CBD is subjected to vacuum drying to remove volatile remnants, in particular the solvent used in crystallizing or re-crystallizing, if needed.
In particular, a method comprising extraction with isopropanol and crystallization by the use of heptane, including one or more optional re-crystallization steps, followed by vacuum drying can provide CBD with crystal structure A, i.e. needle like crystals. Furthermore, such a CBD can be very low in undesired compounds, such as terpenes.
GC chromatography or other analytical methods known in the art can be used to monitor the process such as to ensure a high yield and/or a high purity of the desired product.
Concerning the raw material, hemp comprising e.g. 2-3% CBD is dried and ground before extraction with isopropanol, such as food grade isopropanol.
Guidance for choosing the appropriate reaction based on the boiling points or ranges of the different compounds can e.g. be found here: www.nwsci.com/customer/docs/SKUDocs/RMR/Technical%20Data_Extractions_03.28.18.pdf.
CBD with crystal structure A can e.g. be provided from www.enecta.com, and/or following a similar extraction and/or purification protocol as said manufacturer.
Two nasal sleep compositions are prepared as disclosed herein, such as according to Example 1, 5 and/or 7, the only difference being that the crystalline CBD used in the formulation is either of type A (needle-like crystals;
Type A crystalline CBD is sourced from Enecta, while type B CBD is sourced from Pharma Hemp. Further details can e.g. be found in the first aspect of the invention, such as Table 1.
When testing both nasal sleep compositions, surprisingly and unexpectedly, it is seen and/or it can be concluded that type A CBD is significantly more active than type B CBD.
