| titleOfInvention | METHOD FOR ISOLATING AND CLEANING NALTREXONE |
| abstract | The invention describes a method for purifying a naltrexone base from a concentrated evaporation reaction mixture and / or from mixtures containing naltrexone in the presence of other organic or inorganic substances by trituration and / or extraction and crystallization from cyclopentyl methyl ether (CPME), optionally from a mixture of cyclopentyl methyl ether and organic solvent. Using this method, high-quality naltrexone is obtained (in purity and content), which can be used in parenteral dosage form. |
