  • Patent number: 11911508
    Abstract: The present invention relates to: sustained-release microparticles capable of maintaining, for a long time, effects of preventing, treating or alleviating benign prostatic hyperplasia and prostate cancer and effects of preventing hair loss and promoting hair growth according to the administration of microparticles containing dutasteride; and a preparation method therefor, and according to the use of a method for administering the particles to a patient through an injection, a patient does not have to directly store or handle the microparticles, unlike an oral dosage form, and thus storage and handling are simple. In addition, drug effects are maintained for a long period of time of 1-3 months and, simultaneously, administration through injection can be facilitated since foreign body sensation and pain are reduced when being administered to a patient through injection because of the constant average diameter of the particles.

  • Patent number: 11890393
    Abstract: Disclosed are methods, devices and materials for the in situ formation of a nerve cap to inhibit neuroma formation following planned or traumatic nerve injury. The method includes the steps of identifying a severed end of a nerve, and positioning the severed end into a cavity defined by a form. A transformable media is introduced into the form cavity to surround the severed end. The media is permitted to undergo a transformation from a first, relatively flowable state to a second, relatively non flowable state to form a protective barrier surrounding the severed end. The media may be a hydrogel, and the transformation may produce a synthetic crosslinked hydrogel protective barrier. The media may include at least one anti-regeneration agent to inhibit nerve regrowth.
