Methotrexate (MTX) is a versatile drug used in various fields, including oncology and rheumatology, acting by inhibitory effects on DNA synthesis and cellular replication. While low-dose MTX is a first-line treatment for rheumatoid arthritis and psoriasis, overdose or incorrect dosing can lead to severe toxicity. We present three cases of accidental MTX poisoning, highlighting the diverse clinical manifestations and challenges in management. Patients presented with fever, weakness, mucocutaneous lesions, and pancytopenia, necessitating intensive care and supportive treatment. These cases underscore the importance of proper dosing, patient education, and pharmacist vigilance to prevent medication errors. Heightened awareness among clinicians is crucial to promptly recognize and manage MTX toxicity, ensuring the safe and effective use of this valuable therapeutic agent. Further research is needed to optimize dosing strategies and enhance safety measures for MTX administration.
甲氨蝶呤(MTX)是一种用途广泛的药物,应用于包括肿瘤学和风湿病学在内的各个领域,其作用机制是抑制DNA合成和细胞复制。虽然低剂量甲氨蝶呤是类风湿性关节炎和银屑病的一线治疗药物,但过量用药或剂量不当会导致严重毒性。我们报告了3例甲氨蝶呤意外中毒病例,突出了其多样的临床表现及管理方面的挑战。患者出现发热、乏力、黏膜皮肤病变和全血细胞减少,需要重症监护和支持治疗。这些病例强调了正确给药、患者教育以及药剂师保持警惕以预防用药错误的重要性。临床医生提高认识对于及时识别和处理甲氨蝶呤毒性至关重要,以确保安全有效地使用这种有价值的治疗药物。需要进一步研究以优化给药策略并加强甲氨蝶呤给药的安全措施。
