摘要:
An electrotransport system for delivery of an electrotransport cationic drug. The system has an anode that has a precipitating anion source. The precipitating anions from the precipitating anion source combines with metal ions generated from sacrificial metal of the anode during electrotransport to form precipitates. Metal that can form the metal ions are embedded in the anode.
摘要:
Pharmaceutical formulations comprising perindopril or its salts, isomers, enantiomers, polymorphs, metabolites, solvates, hydrates, and mixtures thereof, and at least one surface stabilizer. Also disclosed are methods of stabilizing perindopril in the formulations, and polyoxyethylene-polyoxypropylene block copolymers as surface stabilizers.
摘要:
An electrotransport system for delivery of a cationic drug. The system has a donor anodic reservoir having an insoluble biocompatible polymeric anion source embedded in the reservoir. The anion source has precipitating anions that can precipitate out metal ions generated from sacrificial metal of the anode during electrotransport.
摘要:
An electrotransport system for delivery of lisuride or a pharmaceutically acceptable salt thereof. The system has a donor electrode assembly, a counter electrode assembly, and a controller electrically connected to the donor electrode assembly and the counter electrode assembly. The donor electrode assembly has a donor reservoir that contains a lisuride salt. The controller is electrically connected to the donor and counter electrode assemblies and is operatable for controlling current for the electrotransport.
摘要:
An oxide and an oxynitride films and their methods of fabrication are described. The oxide or the oxynitride film is grown on a substrate that is placed in a deposition chamber. A silicon source gas (or a silicon source gas with a nitridation source gas) and an oxidation source gas are decomposed in the deposition chamber using a thermal energy source. A silicon oxide (or an oxynitride) film is formed above the substrate wherein total pressure for the deposition chamber is maintained in the range of 50 Torr to 350 Torr and wherein a flow ratio for the silicon source gas (or the silicon source gas with the nitridiation source gas) and the oxidation source gas is in the range of 1:50 to 1:10000 during a deposition process.
摘要:
A silicon comprising film and its method of fabrication is described. The silicon comprising film is grown on a substrate. A hexachlorodisilane (HCD) source gas is one of the reactant species used to form the silicon comprising film. The silicon comprising film is formed under a pressure between 10 Torr and 350 Torr.
