    • PROBLEM TO BE SOLVED: To provide a slow disintegrating oral film that disintegrates at a rate that maximizes the absorption of the nicotine active through the oral mucosa, which thereby effectively delivers a dose of nicotine active to a user in a sufficient amount to reduce or eliminate nicotine craving associated with the cessation of tobacco usage.SOLUTION: A single layer disintegrable oral film having high mucoadhesivity to the oral mucosa and slow disintegration rate includes 45 to 90 wt.% of at least one water soluble polymer, on the basis of the total weight of the dry film, and a nicotine active. The oral film maintains at least partial integrity and nicotine active agent release capability after in vitro exposure to artificial human saliva solution for at least 15 minutes, and comprises a mixture of polyethylene oxide of which molecular weight is 100,000 to 8,000,000 and hydroxypropyl methylcellulose.
    • 要解决的问题:提供缓慢崩解的口腔膜,其以通过口腔粘膜使尼古丁活性物质的吸收最大化的速率崩解,由此有效地向使用者输送一定量的尼古丁活性,以减少或消除 与烟草使用停止相关的尼古丁渴望。解决方案:对口腔粘膜具有高粘膜粘性和缓慢崩解速率的单层崩解口腔膜包含至少一种水溶性聚合物的45至90重量%,基于总计 干膜的重量和尼古丁活性物质。 口腔膜在体外暴露于人造唾液溶液至少15分钟后维持至少部分完整性和尼古丁活性剂释放能力,并且包含分子量为100,000至8,000,000的聚环氧乙烷和羟丙基甲基纤维素的混合物。
