Abstract: The invention relates to crystalline folate salts. The salt consists of a folate anion and an organic cation. The folate anion is 5-methyl-(6S)-tetrahydrofolic acid, and the cation is an organic compound which is an alkanolamine selected from the group consisting of choline, N-methylaminoethanol, 2-amino-2-methylpropanol and 2-dimethylaminoethanol.

Abstract: Preparations of folate for use in the treatment of eye disorders in the presence of elevated intraocular pressure. Methods of reducing intraocular pressure in a patient having an eye disease.

Abstract: The administration of leucovorin as well as other active, reduced folates is useful as an antidote to drugs which act as folic acid antagonists and in combination chemotherapy with 5-FU. The most often used calcium salts of the folates have a low solubility in water and form almost insoluble degradation products. Therefore, aqueous solutions are unstable and precipitates result. Precipitates in injectable products present an unacceptable safety risk to patients. Stable high strength pharmaceutical aqueous compositions are formed containing calcium salts, magnesium or zinc salts of the reduced folates leucovorin, (6R,S)-tetrahydrofolic acid, (6S)-tetrahydrofolic acid, 5,10-methylene-(6R,S)-tetrahydrofolate, 5,10-methylene-(6R)-tetrahydrofolate, 5-methyl-(6R,S)-tetrahydrofolate or 5-methyl-(6S)-tetrahydrofolate and one or more of the compounds sodium gluconate, potassium gluconate, glycerophosphate disodium salt or glycerophosphate dipotassium salt.

Abstract: The administration of levoleucovorin is useful as an antidote to drugs which act as folic acid antagonists and in combination chemotherapy with 5-FU. The most often used calcium salt of levoleucovorin has a limited solubility in water and forms almost insoluble degradation products. Therefore aqueous solutions are unstable and precipitates are resulting. Precipitates in injectable products present an unacceptable safety risk to patients. Stable high strength pharmaceutical aqueous compositions containing calcium salts, magnesium or zinc salts of levoleucovorin and one or more of the compounds sodium gluconate, potassium gluconate, glycerophosphate disodium salt or glycerophosphate dipotassium salt are disclosed.
