  • Publication number: 20240082160
    Abstract: An amlodipine dry suspension, comprising a diluent, a suspending aid, etc. and being free of surfactants. A preparation method therefor comprises the following steps: a) preparing an aqueous mixture 1 containing amlodipine besylate by using a high-speed homogenization method; b) adding sodium benzoate to the mixture 1, and homogenizing same at a high speed to obtain a mixture 2; and c) granulating the mixture 2 and other components, and then drying same. The raw materials are homogenized and mixed at a high speed, no surfactant is added during the preparation, amlodipine is fully wetted by using a high-speed homogenization process, prescription components are simplified, and the amlodipine dry suspension is more suitable for children to use. Compared with ultrasonic stirring, scaled-up and industrial production are easier to realize for the high-speed homogenization process, and at the same time, the preparation is good in stability and convenient to carry.

  • Publication number: 20180051679
    Abstract: A thruster comprising: a chamber to contain a fluid; a plurality of nozzles to exhaust neutral particles derived from the fluid in the chamber, wherein each nozzle has a converging section and the converging section includes a first electrode; a second electrode located distal to the first electrode to provide a voltage differential between the first and second electrodes sufficient to create plasma ions from the fluid and the voltage differential accelerates the plasma ions on a flow path through the converging section, and wherein at least one or more of the accelerated plasma ions are neutralised to form the neutral particles by charge exchange with other neutral particles, or by recombination with electrons, on the flow path.
