Definitions
- the present invention relates to granulates containing lactose particles and a binding component comprising a cannabinoid and a sucrose fatty acid mono-ester. These granulates are particularly suited for use in dosage units that are intended for peroral administration.
- the invention also provides a method for the manufacture of the granulates.
- Biological availability of pharmaceutical substances taken perorally depends on the extent to which the pharmaceutically active substance is absorbed from the intestinal environment across the intestinal mucosa. Hydrophobic pharmaceutical substances are generally poorly absorbed from the intestinal environment, inter alia because of their poor solubility and/or dispersibility in water.
- the biological availability of pharmaceutical substances taken perorally is furthermore greatly dependent on their susceptibility to the so-called first pass effect
- cannabinoids examples are known in which more than 90% of the ingested dose is removed from the blood stream during the first pass.
- the substance is rapidly released from the delivery system into the aqueous environment covering the mucosal surface so that it can be absorbed across said mucosal tissue.
- a pharmaceutically active substance is poorly water-soluble or water-dispersible, it is a major challenge to formulate a delivery system that will achieve fast release of the pharmaceutically active substance in the fluid surrounding the mucosa so as to enable effective absorption of the pharmaceutically active substance by the mucosal tissue.
- WO 2008/033024 A2 describes dosage units for sublingual, buccal or oral administration of water-insoluble pharmaceutically active substances.
- Example 1 describes the preparation of a monophasic microgranulate comprising ⁇ -9-tetrahydrocannabinol, and sucrose monolaurate in a weight ratio of 1:15 using a dry granulation process.
- Example 3 of this patent application describes the manufacture of a tabletting powder for direct compression using 50 g of the microgranulate obtained from Example 1 and 17 g of other components including 5 g of lactose and the compression to 7 mm tablets with a total weight of 60 mg. This patent application does not describe peroral administration.
- WO 02/064109 A2 describes a pharmaceutical formulation for use in administration of a lipophilic medicament via a mucosal surface, which formulation comprises at least one lipophilic medicament and at least one self emulsifying agent, wherein the formulation, upon hydration, forms an emulsion containing the lipophilic medicament which is capable of adhering to a mucosal surface and allowing controlled release of the medicament.
- pharmaceutical formulations in the form of a gel or a compressed tablet for administration of a lipophilic medicament via the sublingual and/or buccal mucosa wherein the tablet or gel, upon contact with saliva, forms an emulsion containing the lipophilic medicament that adheres reversibly to the sublingual and/or buccal mucosa.
- Example 6 of the patent application describes the preparation of a tablet for buccal or sublingual administration by dissolving glyceryl monostearate, polysorbate 80, ascorbyl palmitate and ⁇ -tocopherol and THC in alcohol, spraying the alcoholic solution onto a powder mix consisting of lactose and soluble starch, evaporating the alcohol, dusting the resulting granulate with talc and compressing to a target tablet weight of 101 mg.
- WO 02/064109 A2 aims at absorption via the sublingual and/or buccal mucosa since it is stated that medicaments taken perorally, i.e. taken by ingestion, are subject to the so-called first pass effect which would considerably limit the biological availability of the pharmaceutical substance.
- WO 2005/004848 A1 relates to solid dispersions comprising tacrolimus and solid surfactant having a hydrophile lipophile balance (HLB) value higher than or equal to about 7.
- HLB hydrophile lipophile balance
- Example 19 describes the preparation of the solid dispersion of tacrolimus.
- Tacrolimus (30 g) was dissolved in the mixture of ethanol (100 ml) and dichloromethane (50 ml).
- the solution was sprayed on lactose (300 g) that was fluidized in a fluid bed granulator, and then dried.
- the inventors have developed a granulate comprising granules made of lactose particles held together by a binding component comprising a cannabinoid and a lipophilic matrix.
- This lipophilic matrix contains at least 80 wt. % of sucrose mono-ester of a C 8 -C 18 fatty acid.
- sucrose fatty acid mono-ester acts as a binder itself and enables the formation of a granulate with the cannabinoid.
- the granulates of the present invention can be easily processed into oral dosage units in the form of tablets for peroral delivery.
- the present inventors have surprisingly found that peroral administration of the dosage units according to the present invention results, despite the first pass effect, in sufficient bioavailability of the cannabinoid.
- granulate refers to a particulate material that consists of small discrete particles, the so-called granules.
- a granule is an aggregation of component particles that is held together by physical forces. In a wet granule, these forces are due to the surface tension and due to capillary forces of a liquid binding component. These forces are also responsible for the initial agglomeration of the component particles.
- granulation in the context of the present invention is understood to be a process that converts a mixture of powders, the particles of which have poor cohesion, into aggregates capable of compaction. Unless indicated otherwise, the term granulation as used herein refers to the process of ‘wet granulation’.
- oral or ‘peroral’ as used herein, unless indicated otherwise, refers to a mode of administration that involves ingestion of the dosage unit without significant residence lime in the oral cavity.
- mass weighted average diameter refers to the average diameter of particulate matter as measured by analytical sieve analysis (see for example H.G. Brittain, Pharmaceutical Technology , December 2002, pp 56-64).
- analytical sieve analysis see for example H.G. Brittain, Pharmaceutical Technology , December 2002, pp 56-64.
- sieves are stacked on top of each other in ascending degrees of coarseness, and the powder to be tested is placed on the top sieve.
- the nest of sieves is subjected to a standardized period of agitation, which causes the powder sample to distribute between the sieves.
- the weight percentage of powder retained in each sieve size range is determined.
- the ‘mass weighted average diameter’ is than obtained from a plot of the cumulative weight distribution versus sieve mesh size by determining the mesh size corresponding to 50 wt. % of total powder mass.
- a first aspect of the invention relates to a granulate comprising granules made up of 40-99 wt. % of lactose particles and 1-60 wt. % of a binding component that holds together the lactose particles within the granules, said granules having a mass weighted average diameter of 50-500 ⁇ m and said binding component being a solid dispersion or a solid solution of 10-75 wt. % of a cannabinoid in 25-80 wt. % of a lipophilic matrix, said lipophilic matrix containing at least 80 wt. % sucrose fatty acid mono-ester, the fatty acid residue being selected from C 8 -C 18 fatty acids.

- the phase comprising lactose particles is hydrophilic in nature.
- the phase comprising the binding component comprises the cannabinoid and an amphiphilic sucrose fatty acid mono-ester and is thus hydrophobic/lipophilic in nature.
- the phase comprising the binding component can be a solid dispersion or a solid solution.
- a solid dispersion is a dispersion of one or more compound(s) in a carrier at solid state.
- the dispersed compounds can consist of individual molecule unities or of clusters such as in particles.
- a solid solution in the context of the present invention is a true mixture of compounds that is homogeneous at the molecular level.

- the rate of dissolution of the pure cannabinoid was also measured according to the same method for comparison.
- the dissolution media consisted of a solution of 1 wt. % SDS in water and a pH of 7 readjusted with dilute HCl. During the experiments the temperature of the dissolution media was maintained between 36 and 41° C. under stirring. After dropping the tablet in the dissolution media, samples were taken at various time intervals with the use of a disposable syringe. The samples were filtered immediately over a syringe filter into a HPLC vial and analyzed by HPLC.
- FIG. 1 depicts results from dissolution test of different cannabinoids formulated according to the present invention.
- the weight percentage (wt. % cannabinoid) refers to the weight of the cannabinoid found in the dissolution medium as compared to the total weight of the cannabinoid present in the tablet that is added to the dissolution medium.
- the results demonstrate the favourable effect of the present invention on the rate of dissolution of cannabinoid in aqueous media.
- Tablets prepared from granulate A as described in example 3 were compared with tablets prepared according to example 6 in patent WO 02/064109 A2 via a dissolution test as described in example 3.
- composition of comparative example A Components wt. % Ascorbic Acid 0.1 Tocopherol 0.2 Glyceryl Monostearate (GMS) 5.0 Tween 80 0.5 THC 5.0 Starch 10.0 Lactose (direct compression grade*) 79.2 *mass weighted average diameter ⁇ 250 ⁇ m
- dissolution results of THC from tablets prepared as in example 6 of WO 02/064109 A2 and from tablets prepared as in example 3 from granulate A are compared.
- the weight percentage (wt. % THC) refers to the weight of the THC found in the dissolution medium as compared to the total weight of the THC present in the tablet that is added to the dissolution medium.
- the dissolution rate of the THC is less than when THC is formulated according to example 3 of this patent.
- Tablets were prepared as in example 4 with the only difference that the amphiphilic compound sucrose fatty ester (SML) was substituted by glyceryl monostearate (GMS).
- SML amphiphilic compound sucrose fatty ester
- GMS glyceryl monostearate
- sucrose fatty acid mono-ester (SML) and glyceryl monostearate (GMS) on THC dissolution are compared.
- the weight percentage (wt. % THC) refers to the weight of the THC found in the dissolution medium as compared to the total weight of the THC present in the tablet that is added to the dissolution medium.
- Tablets containing GMS in their formulation do not even comply with the Ph. Eur. specification for oral dosage forms (75% of the API must be released within 45 min). After 60 min not even 70% of all the THC has been released in the dissolution media, while with tablets from granulate A 90% of the THC release was achieved within 15 min.
