Most likely, the solubility of gabapentin decreases at lower temperatures and falls below 100 mg/mL in refrigerated condition. Therefore, preparations of gabapentin 100 mg/mL compounded in Oral Mix and Oral Mix SF should not be refrigerated. Gabapentin (Neurontin) is a pharmaceutical agent, specifically a GABA analogue. Find all the information about Gabapentin (Neurontin) for cell signaling research. Solubility of gabapentin anhydrate/monohydrate in alcohol-water mixtures was experimentally determined. An interesting trend of the solubility was found, which showed both maximum and minimum solubility with different solvent compositions at one temperature. Gabapentin is a gamma-amino acid that is cyclohexane substituted at position 1 by aminomethyl and carboxymethyl groups. Used for treatment of neuropathic pain and restless legs syndrome. It has a role as an anticonvulsant, a calcium channel blocker, an environmental contaminant and a xenobiotic. It is functionally related to a gamma-aminobutyric acid. DESCRIPTION Neurontin® (gabapentin) Capsules, Neurontin (gabapentin) Tablets, and Neurontin (gabapentin) Oral Solution are supplied as imprinted hard shell capsules containing 100 mg, 300 mg, and 400 mg of gabapentin, elliptical film-coated tablets containing 600 mg and 800 mg of gabapentin or an oral solution containing 250 mg/5 mL of gabapentin. Gabapentin, USP is a white to off-white powder with a pKa1 of 3.7 and a pKa2 of 10.7. It is freely soluble in water, 0.1 N hydrochloric acid, 0.1 N sodium hydroxide and glacial acetic acid; slightly soluble in methanol, very slightly soluble in ethanol, 2-propanol; insoluble in toluene. The log of the partition coefficient (n-octanol/0.05M phosphate buffer) at pH 7.4 is –1.25. Laboratory Procedures Gabapentin is supplied as a crystalline solid. Aqueous solutions of gabapentin can be prepared by directly dissolving the crystalline solid in aqueous buffers. The solubility of gabapentin in PBS, pH 7.2, is approximately 10 mg/ml. We do not recommend storing the aqueous solution for more than one day. Most likely, the solubility of gabapentin decreases at lower temperatures and falls below 100 mg/mL in refrigerated condition. Therefore, preparations of gabapentin 100 mg/mL compounded in Oral Mix and Oral Mix SF should not be refrigerated. Solubility of 2- [1- (aminomethyl)cyclohexyl]acetic acid The solubility of 2- [1- (aminomethyl)cyclohexyl]acetic acid (C 9 H 17 NO 2) is influenced by its unique structure, which includes both aliphatic and functional groups. Here's what you need to know: Polarity: The presence of the amino group and carboxylic acid contributes to the compound's polarity, enhancing its ability to interact with Gabapentin is an anticonvulsant medication used in the management of peripheral neuropathic pains, postherpetic neuralgia, and partial-onset seizures. Gabapentin (CAS 60142-96-3) information, including chemical properties, structure, melting point, boiling point, density, formula, molecular weight, uses, prices Gabapentin Properties Gabapentin, an amino acid structurally related to the neuro-transmitter gamma-aminobutyric acid, is a white to off-white crystalline powder.7 Gabapentin is available as oral hard-gelatin capsules with lactose, corn starch, and talc. It is also available as an oral liquid with glycerin, xylitol, purified water, and artificial flavor.7 Solubility Gabapentin is freely View Gabapentin Datasheet.[1] Fink K, et al. Neuropharmacology, 2002, 42 (2), 229-236. [2] Sills GJ, et al. Curr Opin Pharmacol, 2006, 6 (1), 108-113. [3] Field MJ Gabapentin also decreases pain-related responses after peripheral inflammation (carrageenan footpad test, late phase of formalin test). Gabapentin did not alter immediate pain-related behaviors (rat tail flick test, formalin footpad acute phase, acetic acid abdominal constriction test, footpad heat irradiation test). Solubility of 4-aminohex-5-enoic acid (C 9 H 17 NO 2) 4-aminohex-5-enoic acid, a compound with both a hydrophobic hydrocarbon chain and a hydrophilic amino and carboxylic acid functional groups, exhibits unique solubility properties. It's important to understand the factors influencing its solubility: Solvent Compatibility: This compound is typically soluble in polar solvents due to its ionic Gabapentin: White to off-white, crystalline solid. Freely soluble in water and in alkaline and acidic solutions. In alcohol-water system, gabapentin anhydrate can transform to monohydrate with the increasing of water, which is influenced both by temperature and water activity. The solubility of anhydrate/hydrate have strange trend, especially existing a minimum in water rich region. Molecular dynamics simulations show the water association and solvent-solute interactions are the key factors. Gabapentin is a drug with anticonvulsant activity and has been widely used in the treatment of epilepsy. Gabapentin chemical structure lacks a chromophore which makes its absorption very low and hence complicates its analysis and reduces the Gabapentin | Deranged PhysiologyGabapentin Gabapentin is a gamma-aminobutyric acid analogue, which has been shown to be an effective antiepileptic. The solution stability of gabapentin in buffered systems was studied in order to facilitate the formulation of a liquid product. The degradation of the drug was followed as a function of pH, buff
