The administration of leucovorin as well as other active, reduced folates are 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 are resulting. 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.
亚叶酸及其他活性的、还原的叶酸的使用作为对作为叶酸拮抗剂的药物的解毒剂以及与5-氟尿嘧啶联合化疗是有用的。叶酸的钙盐通常在水中溶解度较低,并形成几乎不溶解的降解产物。因此,水溶液是不稳定的,会产生沉淀。注射产品中的沉淀对患者构成不可接受的安全风险。形成了稳定的高强度药用水性配方,其中包含亚叶酸、(6R,S)-四氢叶酸、(6S)-四氢叶酸、5,10-亚甲基-(6R,S)-四氢叶酸、5,10-亚甲基-(6R)-四氢叶酸、5-甲基-(6R,S)-四氢叶酸或5-甲基-(6S)-四氢叶酸的钙盐、镁盐或锌盐以及一种或多种化合物,如葡萄糖酸钠、葡萄糖酸钾、二钠甘油磷酸盐或二钾甘油磷酸盐。
