  • Publication number: 20230233683
    Abstract: An oral amphetamine extended release liquid suspension is described. The compositions contain a combination of an uncoated amphetamine-cation exchange resin complex, a barrier coated amphetamine-cation exchange resin complex-matrix, and an uncomplexed amphetamine, wherein one or more of these components contains blends of different forms of amphetamines. Either the modified release coated and/or the uncoated amphetamine-cation exchange resin complex may have two forms of amphetamine in a complex with a single cation exchange resin. Following administration of a single dose of the composition, a therapeutically effective amount of amphetamine is reached by about one hour and the composition provides at least a thirteen hour effect post-dose.

  • Patent number: 10274135
    Abstract: A handheld and portable transillumination light source device allows for visualizing and locating vasculature and other subcutaneous structures of the body. One or more forward and upward facing LEDs are provided to project light out of a forward or upper surface of the device respectfully. The LEDs may vary as to the wavelengths of light the LEDs emit. A control button allows a user to switch the device between various modes of lighting, as well as, to adjust the intensity of the LEDs. Alternatively, these buttons may be split into separate power and intensity buttons. Touch sensors or a touch strip may also be provided to adjust the intensity of the LEDs.
