  • INJECTION DEVICE
    Publication number: 20230191030
    Abstract: An autoinjector device is provided. The autoinjector device can include an activator unit including an activation housing, an activation guard, and an activation shell such that a portion of the activation guard extends beyond a proximal end of the activation shell. The autoinjector device can include camouflage on a proximal surface to obscure a device lock hole and reduce user confusion around needle orientation.
    Type: Application

  • Accumulations of amino acids and peptides into liposomes
    Patent number: 5380531
    Abstract: The present invention relates to liposomal compositions having a concentration gradient which load amino acids and peptides exhibiting weak acid or base characteristics into liposomes. Specifically loaded into liposomes by the methods of the present invention are C-terminal substituted amino acids or peptides. The liposomes are preferably large unilamellar vesicles. The concentration gradient is formed by encapsulating a first medium in the liposomes, said medium having a first concentration of the one or more charged species, and suspending the liposomes in a second medium having a second concentration of the one or more charged species, such as for example a pH gradient. Also disclosed are pharmaceutical preparations comprising such C-terminal substituted amino acids or peptides which have been loaded into the liposomes by the method of the invention.
