Abstract: A tumescent composition comprising a chemotherapy agent in a tumescent solution, wherein a tumescent concentration of the chemotherapy agent 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; and the tumescent solution comprises a vasoconstrictor; a pharmaceutically acceptable carrier; and optionally a local anesthetic.

Abstract: A tumescent composition comprising a drug or a therapeutic agent in a tumescent solution, wherein a tumescent concentration of the drug or therapeutic agent 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; and the tumescent solution comprises a vasoconstrictor; a pharmaceutically acceptable carrier; and optionally a local anesthetic, wherein the tumescent solution does not comprise an antibiotic.

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 method of subcutaneous delivery of a drug or a therapeutic agent to a subject to treat a localized condition, the method including obtaining a liquid composition including the drug or the therapeutic agent dissolved in a tumescent solution, wherein the tumescent solution includes the drug or the therapeutic agent a vasoconstrictor; and a pharmaceutically acceptable carrier; and delivering a mass of the liquid composition subcutaneously to a localized tissue in the subject, wherein the drug or the therapeutic agent treats the localized condition in the localized tissue, wherein a concentration of the drug or the therapeutic agent subcutaneously delivered exceeds a concentration of the drug or the therapeutic agent that can be safely achieved by intravenous delivery, and wherein an amount of the drug or the therapeutic agent located at an outer boundary of the mass of fluid and available for absorption is less than an amount of the drug or the therapeutic agent located within a central portion of the mass of

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.

Abstract: A method of subcutaneous delivery of a drug or a therapeutic agent to a subject comprising administering to said subject a mass of fluid of a tumescent composition comprising: (a) the drug or the therapeutic agent; (b) a vasoconstrictor; and (c) a pharmaceutically acceptable carrier, wherein a relatively large total amount of the drug is isolated from systemic circulation in the subject because only drug in an outer boundary of the mass of fluid is the available for absorption, whereas a portion of the drug located within a central portion of the mass of fluid is virtually isolated from the systemic circulation by virtue of profound capillary vasoconstriction, wherein epinephrine-induced vasoconstriction dramatically slows systemic absorption of the drug or therapeutic agent, and wherein the mass of fluid is a reservoir that delivers the drug or the therapeutic agent to the subject with pharmacokinetics that are analogous to a slow-release oral tablet or a slow constant intravenous (IV) Infusion.
