Definitions
- the present invention relates to an oral thin film containing at least one pharmaceutically active ingredient and the use of such an oral thin film as a medicament.
- Oral thin films also known as oral thin films, are thin, flexible films based on a polymer matrix loaded with drug delivery agents. The oral thin films are taken orally and immediately dissolve in the mouth or applied to the mucosa. They are placed on or under the tongue or buccally, where they then dissolve or disintegrate.
- Oral thin films can be nonfoamed films or foamed films or foams.
- OTF are also sometimes referred to as oral thin foils.
- EP 422100 B1 discloses the active ingredient ulipristal acetate. Ulipristal acetate is a well-known emergency contraceptive ("morning after pill”). It is administered as a tablet (“EllaOne®”) containing 30 mg micronized ulipristal acetate and the other ingredients lactose monohydrate, povidone, croscarmellose sodium and magnesium stearate. EllaOne® was approved in the European Union in 2009.
- Ketamine is another well-known pharmaceutical agent that is used in particular to treat or prevent pain.
- known oral thin films with a high active substance loading have the disadvantage that the maximum basis weight and thus the amount of pharmaceutically active active substance contained is determined by the drying of the oral thin film during its production.
- the object of the present invention is to eliminate the disadvantages mentioned above.
- the object of the present invention is to provide flexible and stable oral thin films/foams which allow high drug loading while at the same time having an acceptable film thickness and a fast disintegration time in use.
- this object could surprisingly be achieved by using a mixture of polyvinyl alcohols with different molecular weights in the matrix layer.
- An additional improvement could be achieved by adding humectants, in particular certain sugar alcohols or starch derivatives.
- the invention accordingly relates to an oral thin film comprising at least one matrix layer, the at least one matrix layer containing at least one polyvinyl alcohol with a lower average molecular weight of 10,000 to about 75,000 g/mol, preferably 10,000 to about 40,000 g/mol, and at least a polyvinyl alcohol with a higher average molecular weight of 140,000 to 300,000 g/mol, preferably 140,000 to 220,000 g/mol and at least one pharmaceutical active ingredient, wherein the at least one polyvinyl alcohol with a lower average molecular weight and the at least one polyvinyl alcohol with a higher average molecular weight in a total amount of 15 to 70% by weight, preferably 15 to 65% by weight, based on the total weight of the matrix layer, are present in the matrix layer and the weight ratio of the at least one polyvinyl alcohol with a lower average molecular weight to the at least one Polyvinyl alcohol having a higher average molecular weight is in the range of 20:1 to 2:1.
- the secondary independent claim relates to the use of the oral thin film according to the invention. Preferred embodiments are given in the dependent claims.

- the polyvinyl alcohol used according to the invention with a lower average molecular weight of 10,000 to about 75,000 g/mol, preferably 10,000 to about 40,000 g/mol is referred to below as "low molecular weight polyvinyl alcohol” or "low molecular weight PVA”.
- the polyvinyl alcohol with a higher average molecular weight of 140,000 to 300,000 g/mol, preferably 140,000 to 220,000 g/mol is referred to below as “high molecular weight polyvinyl alcohol” or "high molecular weight PVA”.
- “comprising” can also mean “consisting of”.
- the disintegration time could be improved compared to formulations that only contain low-molecular PVA.
- the longer chain PVA such as PVA 40-88 in this blend is a type of structurant that allows for the incorporation of lower concentrations of PVA.
- the oral thin film of the present invention has at least one matrix layer.
- the at least one matrix layer comprises at least one polyvinyl alcohol with a lower average molecular weight in the range from 10,000 to about 75,000 g/mol, preferably 10,000 to 40,000 g/mol, more preferably 25,000 to 35,000 g/mol, and at least one polyvinyl alcohol with a higher average molecular weight im Range from 140,000 to 300,000 g/mol, preferably 140,000 to 220,000 g/mol, more preferably 200,000 to 210,000 g/mol.
