  • Patent number: 8987328
    Abstract: Provided are nutraceutical or dietary supplemental compositions comprising esterified capsaicinoids. The esterified capsaicinoids may converted to the active parent capsaicinoid compound following enzymatic or chemical hydrolysis. In various embodiments, these esterified capsaicinoids have a higher lipophilicity, lipid solubility and result in less irritation to the stomach than the parent capsaicinoid, and hence may be included in certain dietary supplement formulations, including capsules, pills and tablets dietary supplement formulations. The dietary supplement compositions may be used for pain management in mammals in vivo and/or in the treatment of various pathological conditions in humans.

  • Patent number: 8765807
    Abstract: The present invention relates to the formulations of ester derivatives of capsaicin and ester derivatives of myristoleic acid. These derivatives are capable of reverting to the active parent compound following enzymatic or chemical hydrolysis. These derivatives have a higher lipophilicity, lipid solubility and less irritation to the skin than the parent compound, and hence are better able to be incorporated into certain pharmaceutical formulations, including cream and ointment pharmaceutical formulations. The pharmaceutical compositions are useful for pain management in mammals in vivo and have been contemplated to be used in the treatment of various pains in humans.
