Abstract: The present disclosure provides a delivery system for controlled protein release without encapsulation. Identical, burst-free, extended release profiles for three different protein therapeutics were obtained with and without encapsulation in PLGA nanoparticles embedded within a hydrogel. Using both positively and negatively charged proteins, it was shown that short-range electrostatic interactions between the proteins and the PLGA nanoparticles are the underlying mechanism for controlled release. Moreover, tunable release was demonstrated by modifying nanoparticle concentration, nanoparticle size, or environmental pH. Additionally, the utility of this system was demonstrated in vivo for BDNF delivery in a rat model of stroke. These new insights obviate the need for encapsulation and offer promising, translatable strategies for more effective delivery of therapeutic biomolecules.

Abstract: Aspects of the disclosure include methods for treating hyperhidrosis in a subject with a composition including a muscarinic antagonist and a muscarinic agonist. In practicing methods according to certain embodiments, a therapeutically effective amount of a composition including a muscarinic antagonist or a pharmaceutically acceptable salt thereof and a muscarinic agonist or a pharmaceutically acceptable salt thereof is administered to a subject and is sufficient to reduce hyperhidrosis in the subject and to reduce a dry mouth side effect of the muscarinic antagonist. Compositions for practicing the subject methods are also described as well as dose units containing one or more of the subject compositions.

Abstract: Coaxial electrospinning is used to encapsulate a chitin-lignin based hybrid gel with polycaprolactone (PCL). Antibiotics and/or other bioactive agents loaded into the core and/or shell layer of the fibrous platform are released in a controlled and sustained manner that effectively inhibits both Gram-positive and Gram-negative bacteria without cytotoxicity to mammalian cells. The PCL shell layer provides longer life for the CL gels in a wet environment and allows sustainable drug release. The PCL-coated CL nanofiber scaffolds can be loaded with antimicrobial nanoparticles, antibiotics, oxygen-releasing agents, antioxidants and/or growth factors that promote healing when used as a controlled drug release dressing for chronic wounds, such as diabetic ulcers.
Abstract: A description is given of compositions comprising a) one or more substances selected from the group consisting of hydrogen peroxide and hydrogen peroxide donor substances, b) water, c) one or more polymers having thickening properties and d) one or more substances selected from the group consisting of hydroxypyridones and salts thereof. The compositions are notable more particularly for their advantageous shelf lives.
