  • Publication number: 20230144752
    Abstract: The invention relates to an oral thin film, comprising a polymer matrix and ulipristal acetate as an active agent, wherein ulipristal acetate is dispersed in the polymer matrix and the polymer matrix is a matrix of water-soluble polymer selected from poly(ethylene oxide), poly(vinyl alcohol) or hydroxypropyl methylcellulose. The oral thin film is suitable as emergency contraceptive and can be administered in the oral cavity without water. It quickly disintegrates in the oral cavity wherein the active agent ulipristal acetate is mainly swallowed in undissolved form and absorbed into the gastrointestinal tract.

  • Publication number: 20230136398
    Abstract: The invention relates to an oral thin film, comprising a polymer matrix and at least one water-insoluble, particulate active pharmaceutical ingredient dispersed in the polymer matrix, wherein the matrix polymer is poly(ethylene oxide) having a melting point of at least 55° C., the amount of poly(ethylene oxide) having a melting point of at least 55° C. is at least 40% by weight, based on the total weight of the oral thin film, and wherein the oral thin film is obtainable by a process comprising the steps of: a) preparing a suspension comprising the matrix polymer, the at least one water-insoluble, particulate active pharmaceutical ingredient and a solvent which s water or a mixture of water and one or more organic solvents, b) casting the suspension obtained on a support or in a mold, and c) drying the suspension at a temperature above the melting temperature of the poly(ethylene oxide).

  • Patent number: 8226974
    Abstract: The invention relates to transdermal therapeutic systems which have the active ingredient nicotine and have particularly high flexibility. This flexibility decisively improves wearer comfort on the skin, since the system is readily capable of adapting to the surface of the skin and its constant movement. Surprisingly, the nicotine TTS of the invention is markedly more flexible than the conventional nicotine TTS products which are leaders in the market, although at least some of those systems are comparably thin.
