  • Publication number: 20230266612
    Abstract: A method of manufacturing a light modulation device is disclosed herein. In some embodiments, a method comprises transferring a first substrate between a first unwind roll and a take-up roll, wherein an adhesive layer is disposed on the a first surface of the first substrate, transferring a second substrate between a second unwind roll and the take-up roll, wherein the second substrate includes a spacer and a liquid crystal alignment film formed on a first surface of the second substrate during the transfer and prior to an attachment with the adhesive layer of the first substrate, and attaching the first and second substrates via respective first surfaces thereof by passing the first and second substrates through an opening between adjacent attachment rolls to form a light modulation device.

  • Publication number: 20040248901
    Abstract: The present invention relates to compositions containing itraconazole with a greatly increased bioavailability and their preparation methods. More specifically, the present invention relates to compositions containing itraconazole which is a sparingly-soluble drug, fatty acid or fatty alcohol and surfactant and their preparation methods. Compositions according to the present invention act as Self-MicroEmulsifying Drug Delivery System(SMEDDS) wherein itraconazole which is a sparingly-soluble drug is dissolved and dispersed to form a mocoidal phase, and the mocoidal phase is dissolved in water to form microemulsion. And because of increased dissolution property and increased bioavailability, compositions according to the present invention show equal efficacy using less amount than commercial pharmaceutical preparations such as sporanox capsule and are cheaper rather than the commercial pharmaceutical preparations such as sporanox capsule.

  • Publication number: 20040180961
    Abstract: There are provided compositions and preparation methods for bioavailable oral aceclofenac dosage forms. More particularly, the compositions containing water-insoluble aceclofenac, a polymeric base selected from the group consisting of polyvinyl, methyl cellulose, ethyl cellulose, hydroxypropylmethylcellulose, carboxy methyl cellulose, glyceryl monostearate, carbamer, and poloxamer, and surfactant. The compositions of the present invention can be formulated into compressed particles, granules, tablets, capsules or even semisolid preparations, which significantly increase the bioavilablity due to the improvement of dissolution of the drug in gastrointestinal tract, and reduce the manufacturing cost by simple process.
