Definitions
- a number of physiologically active substances have highly lipophilic properties, i.e. they have a relatively high log P, for example a log P of 4 or more, where the log P is the logarithm of the n-octanol / water partition coefficient.
- WO 2015/065179 A1 describes compressed tablets which, in addition to cannabidiol, contain lactose and sucrose fatty acid monoesters.
- the finished drug Sativex ® which contains nabiximols, is an oral spray that is sprayed onto the inside of the cheek.
- Epidiolex for the treatment of certain forms of epilepsy is made available in the form of an oral solution which, in addition to the active ingredient cannabidiol, contains the auxiliary substances absolute ethanol, sesame oil, strawberry aroma and sucralose.
- Fig. 1 shows the in vitro release from three pellet products, the 2- [1R-3-methyl-6R- (1-methylethenyl) -2-cyclohexen-1-yl] -5-pentyl-1,3-benzenediol as Contains active ingredient and low-viscosity hydroxypropylmethylcellulose as a film-forming agent.
- physiologically active substance refers to a substance that is administered to a human or an animal in order to develop an effect in the human or animal body.
- the physiologically active substance can, for example, be a pharmaceutical active ingredient of a human or veterinary medicinal product or a food supplement.
- the phytocannabinoids are a group of about 70 terpenophenolic compounds (V.R. Preedy (Ed.), Handbook of Cannabis and Related Pathologies (1997)). These compounds typically contain a monoterpene residue attached to a phenolic ring and having a Cs-Cs alkyl chain that is in the meta position to the phenolic hydroxyl group.
- R is selected from C 1 -C 10 -alkyl or C 2 -C 10 -alkenyl and optionally has one or more substituents.
- HPMC Hydroxypropylmethylcellulose
- low-viscosity HPMC such as HPMC with a viscosity of a 2% (w / w) aqueous solution at 20 ° C. of 6 mPa ⁇ s or less.
- the coating of one or more highly lipophilic physiologically active substances and one or more water-soluble film-forming agents can contain other customary auxiliaries.
- the amount of further auxiliaries is limited to not more than 20% by weight, based on the weight of all components. It preferably does not contain more than 10% by weight, based on the weight of all components, of further auxiliaries.
- the coating consists of a strongly lipophilic physiologically active substance / strongly lipophilic physiologically active substances and film-forming agent (s), for example cannabinoid (s) and film-forming agent (s).
- film-forming agent for example cannabinoid (s) and film-forming agent (s).
- Pellets according to the invention have a coating that contains one or more water-soluble film formers, based on the total amount of highly lipophilic physiologically active substances, in a total proportion of 0.1-10% by weight, preferably in a total proportion of 0.5-8% by weight .-% and in particular in a total proportion of 1-6% by weight.
- the release of the physiologically active substance can be adjusted by choosing the proportion in the specified ranges.
- the release from an oral dosage form can be adjusted so that the physiologically active substance is released over the usual time of gastrointestinal passage.
- the size of the cores is not limited. Suitable sizes are in the range from 10 pm to 2000 pm, for example in the range from 50 pm to 1500 pm and preferably 100 pm to 1000 pm, the size being able to be determined by sieve analysis. In particular, pellets from a sieve fraction of 500-710 ⁇ m can be used.
- no further coating is provided which controls the release.
- Coated pellets with different release profiles can be combined in one dosage form (capsule / tablet / sachet).
- the products according to the invention use the strongly lipophilic physiologically active substance contained or, if more than one strongly lipophilic physiologically active substance is contained, all of them contained highly lipophilic physiologically active substances free in the digestive tract after ingestion.
- the products are used in particular for controlled release. In particular, they release more than 30% by weight and less than 80% by weight of the physiologically active substance contained within two hours. Furthermore, they release in particular more than 40% by weight and less than 90% by weight of the physiologically active substance contained within three hours. In addition, they release more than 50% by weight and less than 95% by weight of the physiologically active substance contained within four hours. If it contains more than one physiologically active substance, the information relates to all substances contained.
- HPMC solution was then gradually added to the cannabidiol solution.
- amorphous silica (Syloid ® 244 FP) was added.
- the spray liquid obtained was sprayed onto starter cores made of microcrystalline cellulose (Cellets ® 500).
- Example 1 pellet products The release from the results obtained in Example 1 pellet products is examined using a blade stirrer apparatus in 1000 ml phosphate buffer pH 6.8 with an addition of 0.4% Tween ® 80, namely at 37 ° C. The results obtained 1 are shown in Fig..
