  • Patent number: 10464887
    Abstract: The present invention provides a method for producing an active ingredient for a rivastigmine free base transdermal patch having preparing a rivastigmine free base; and adding an acidic substance to the rivastigmine free base and subjecting the acidic substance and the rivastigmine free base to a mixed reaction to form a mixture having a pH value from 6.0 to 8.5 as the active ingredient; and a rivastigmine free base transdermal patch having a drug layer comprising the active ingredient. The rivastigmine free base transdermal patch has a stable transdermal transmission time equal to or longer than 48 hours and equal to or less than 168 hours. The active ingredient produced by the method and the transdermal patch having the active ingredient allow effective and smooth release of rivastigmine free base and prolongs the release time to meet the clinical application needs.

  • Publication number: 20110178044
    Abstract: Methods, formulations, and drug delivery systems are provided for enhancing the flux of a transdermally administered hydrophilic drug using a basic permeation enhancer composition. The enhancer composition contains an inorganic hydroxide and a weaker, nitrogenous base, wherein the bases are selected such that a 0.1M aqueous solution of the nitrogenous base has a pH that is about 1.0 to about 6.5 lower than the pH of a 0.1M aqueous solution of the inorganic hydroxide. Additionally, the molar ratio of the nitrogenous base to the inorganic hydroxide in the enhancer composition is in the range of about 0.5n:1 to about 20n:1, where n is the number of hydroxide ions per molecule of the inorganic hydroxide.

  • Patent number: 7506787
    Abstract: A nail-driving device has a housing, a trigger unit, a safety unit, a connecting unit and a magazine. The safety unit has first and second safety members in the housing. The connecting unit is connected pivotally to the second safety member, and has a retaining portion disposed movably between the first and second safety members. The magazine has a pusher for pushing nails therein. When the retaining portion is in a retaining position, a force is applicable to the first safety member to move the second safety member to pivot a trigger arm for a nail-driving operation when the trigger unit is actuated. When the nails thereof are exhausted, the pusher moves to a retention releasing position to pivot the connecting unit and remove the retaining portion from the retaining position to allow for relative movement of the first and second safety members to prevent the nail-driving operation.

  • Publication number: 20080262445
    Abstract: A method and related compositions, including the use of N-acyl derivatives of sarcosine, provide for the delivery of bioactive agents through tissue surfaces such as the skin. The method and composition are particularly well suited for hydrophobic active agents such as serotonin (5HT3) receptor antagonists (e.g., ondansetron), antipsychotic agents (e.g., risperidone), benzodiazepines (e.g., flumazenil), and progestins (e.g., levonorgestrel).

  • Patent number: 7398905
    Abstract: The present invention provides an anti-misfit structure for a nail cartridge, which resolves the problems of a typical nail cartridge. For example, when a short collated nail is mistakenly inserted, it is likely lead to different triggering strength, and easier swinging and jamming of nail bodies against stability and safety. The swinging end of the spring of the nail cartridge is provided with a stopper. So, when the nailer head of a short collated nail is mistakenly inserted into the long nailer head dent, the stopper blocks the collated nail, thus preventing any misalignment and subsequent triggering of a nailer for higher stability and safety.

  • Publication number: 20080138390
    Abstract: The present invention includes transdermal delivery systems having a polymeric active agent reservoir fabricated from an admixture of polyisobutylene and an insoluble hydrophilic polymer in powdered form, which provide numerous advantages in the transdermal delivery of active agents using basic enhancer compositions. For example, the systems of the invention provide for (1) increased permeation of the active agent through the skin, (2) an improved capability of extracting the active agent and enhancer from the transdermal systems, (3) enhanced structural integrity, (4) good chemical stability, (5) reduced phase separation, and (6) decreased cold flow.
