Nicotinamide riboside and derivatives thereof in intravenous formulations and methods of use thereof
A stable intravenous (I.V.) composition includes nicotinamide riboside (NR) as described, or other nicotinyl riboside compounds which are NAD+ precursors, in said intravenous form. NR chloride may be provided in an intravenous (I.V.) formulation for administration to a human subject.
1 . A method for administration of nicotinamide riboside, a salt thereof, or a solvate thereof to a human subject, comprising the steps of: (a) providing a sterile aqueous-based I.V. or injectable formulation containing NR, a salt thereof, or a solvate thereof; and (b) intravenously, subcutaneously, parenterally, or intramuscularly administering the formulation to the human subject by injection or infusion in an amount effective to reduce one or more side effects causing discomfort and/or maintain a comfort level in the human subject, wherein the sterile aqueous I.V. or injectable formulation is administered over about 0.5 hours to about 3 hours.
2 . The method of claim 1 , further comprising step (c):
(c) continuously measuring and monitoring the side effects and/or comfort level of the human subject during the administration of the formulation to ensure that the side effects are reduced.
3 . The method of claim 1 , wherein the one or more side effects causing discomfort are selected from the group consisting of a pain response, burning sensation, generalized discomfort, headache, nausea, gastrointestinal discomfort, gastrointestinal upset, cramps, nerve tingling, chest discomfort, labored breathing, and muscle weakness.
4 . The method of claim 2 , wherein the side effect of steps (b) and (c) is a pain response which is minimized during and after administration of the sterile aqueous formulation.
5 . The method of claim 1 , wherein the side effect is a generalized discomfort which is minimized during and after administration of the sterile aqueous formulation.
6 . The method of claim 1 , wherein the nicotinamide riboside salt is a chloride salt (NR-Cl).
7 . The method of claim 1 , wherein the nicotinamide riboside salt is selected from the group consisting of bromide, iodide, fluoride, formate, acetate, propionate, butyrate, glutamate, aspartate, ascorbate, benzoate, carbonate, citrate, carbamate, gluconate, lactate, methyl bromide, methyl sulfate, nitrate, phosphate, diphosphate, succinate, sulfate, tartrate, hydrogen tartrate, malate, hydrogen malate, maleate, fumarate, citrate, stearate, palmitate, myristate, laurate, caprate, caprylate, caproate, oleate, linoleate, sulfonate, trifluoromethanesulfonate, trichloromethanesulfonate, tribromomethanesulfonate, trichloroacetate, tribromoacetate, and trifluoroacetate.
8 . The method of claim 6 , wherein the nicotinamide riboside chloride salt is crystalline Form I, Form II, or a combination thereof, or a lyophilized or freeze-dried powder thereof.
9 . A method for administration of nicotinamide riboside, a salt thereof, or a solvate thereof to a human subject, comprising the steps of: (a) providing a sterile aqueous-based I.V. or injectable formulation containing NR, a salt thereof, or a solvate thereof; and (b) intravenously, subcutaneously, parenterally, or intramuscularly administering the formulation to the human subject by injection or infusion in an amount effective to reduce one or more side effects causing discomfort and/or maintain a comfort level in the human subject, wherein the sterile aqueous I.V. or injectable formulation is administered over less than about 0.5 hour.
10 . The method of claim 6 , wherein the NR-Cl is administered in a daily dose of from about 25 mg to about 3000 mg.
11 . The method of claim 6 , wherein the NR-Cl is administered in a daily dose of from about 500 mg to about 1000 mg for intravenous administration.
12 . The method of claim 1 , wherein the aqueous-based I.V. or injectable formulation further contains a compound selected from the group consisting of nicotinamide adenine dinucleotide (NAD+),-(2′,3′,5′-triacetyl-beta-D-ribofuranosyl)-nicotinamide (NRTA), Nicotinic acid riboside (NAR), Reduced nicotinamide mononucleotide (NMNH), Nicotinamide Mononucleotide (NMN), Nicotinic acid mononucleotide (NaMN), Reduced nicotinic acid mononucleotide (NaMNH), Reduced nicotinamide riboside (NRH), Reduced nicotinic acid riboside (NARH), 1-(2′,3′,5′-triacetyl-beta-d-ribofuranosyl)-nicotinic acid (NARTA), 1-(2′,3′,5′-triacetyl-beta-d-ribofuranosyl)-1,4-dihydronicotinamide (NRH-TA), and 1-(2′,3′,5′-triacetyl-beta-d-ribofuranosyl)-1,4-dihydronicotinic acid (NARH-TA), or salts thereof.
13 . The method of claim 12 , wherein the one or more side effects measured during step (b) is reduced.
14 . The method of claim 9 , wherein the nicotinamide riboside salt is a chloride salt (NR-Cl).
