Abstract: A tumescent composition including a cannabinoid dissolved in a tumescent solution, wherein the tumescent solution includes a local anesthetic; a vasoconstrictor; and a pharmaceutically acceptable carrier, wherein a tumescent concentration of the cannabinoid is 1-2000 ?g/kg and is simultaneously: below a threshold for local, subcutaneous tissue toxicity, above a threshold for positive local therapeutic effect, and above a concentration safely achievable by intravenous (IV), intramuscular (IM) or oral (PO) delivery. Also disclosed are methods of subcutaneous delivery of a cannabinoid to a subject including administering to the subject the tumescent composition.

Abstract: A tumescent solution including: a vasoconstrictor; a B vitamin and a pharmaceutically acceptable carrier. In some examples, the tumescent solution further includes a drug or therapeutic agent dissolved in the tumescent solution. Some examples relate to a method of subcutaneous delivery of a drug or therapeutic agent to a subject including subcutaneously administering to said subject a tumescent solution as disclosed herein. In some examples, infiltration of the tumescent solution achieves both prolonged local drug or therapeutic agent concentration within a tumescent subcutaneous tissue as well as a prolonged slow constant systemic absorption of drugs from the tumescent tissue into a systemic circulation. In some examples, the tumescent solution reduces neuropathic pain or the risk of developing neuropathic pain, treats a localized condition or reduces persistent postsurgical pain (PPP) in a subject.

Abstract: A tumescent contravenom solution including: (a) a vasoconstrictor, (b) a physiological crystalloid solution, and (c) optionally a contravenom agent that neutralizes tissue toxic enzymes present in a venom and/or a drug that impairs or paralyzes lymphatic smooth muscle function and impairs lymphatic transport of venom. Also described are methods of treating an envenomation in a subject, and a kit for performing the method of treating an envenomation.
