    • A composition and method for the treatment of the side-effects associated with the administration of cancer chemotherapeutic agents involves the oral ingestion of a slow release capsule containing adenine. In some embodiments, the slow release capsule also contains orotate. The systemic administration of a proton pump inhibitor decreases systemic absorption of orotate, and the systemic administration of allopurinol decreases the formation of 2,8-dihydroxy adenine from adenine. In an alternative embodiment, cationic liposomes contain purine/pyrimidine precursors. The cationic liposomes bind to the cells lining the mucosa of the intestinal tract and then the contents of the cationic liposome are then taken up in the interior of the cells to prevent the metabolism of the cancer treatment drug 5-FU into a toxic species. A method for prevention of oral stomatitis and a method for treatment of dysplastic tissue are also disclosed.
    • 用于治疗与癌症化学治疗剂的给药相关的副作用的组合物和方法涉及口服摄取含有腺嘌呤的缓释胶囊。 在一些实施方案中,缓释胶囊还含有乳清酸。 质子泵抑制剂的全身给药减少了乳清酸的全身吸收,并且全身施用别嘌呤醇降低了腺嘌呤形成的2,8-二羟基腺嘌呤。 在另一个实施方案中,阳离子脂质体含有嘌呤/嘧啶前体。 阳离子脂质体结合到肠道粘膜上的细胞,然后将阳离子脂质体的内容物吸收到细胞内部,以防止癌症治疗药物5-FU的代谢成为毒性物质。 还公开了预防口腔炎的方法和治疗发育不良组织的方法。
