Essential oxygen oil (OxyRub from CreoMed Inc., Naples, FL, U.S.A.) is a novel topical analgesic currently commercially available in Europe and now available in the U.S.A. It represents an important alternative to other treatments (nonsteroidal anti-inflammatory drugs, acetaminophen, menthol, camphor) for managing mild to moderate acute and chronic pain. Several clinical trials of this oil will be reviewed.
One large (n = 455) open-label trial found essential oxygen oil to be a safe and effective analgesic for a broad range of patients with acute and chronic pain. In that study, 80% of patients reported that their pain decreased by more than 75%. A double-blind placebo-controlled study (n = 50) found significant pain reduction for tendonitis in patients using essential oxygen oil. Another trial of essential oxygen oil vs. placebo (n = 50) with various pain diagnoses found that 98% of patients with various pain diagnoses reported "very good" pain relief in the oil group compared to 48% in the placebo group. Furthermore, a randomized controlled trial in 10 women to measure oxygen microcirculatory effect in the skin showed an increased microcirculatory effect with improved oxygenation (increased partial pressure of oxygen in the skin) after application of essential oxygen oil. In all studies, the oil was well tolerated. None of these studies has been previously published.
Based on studies completed, essential oxygen oil has shown itself to be safe, has demonstrated positive analgesic effects for the treatment of acute and chronic pain, and has improved oxygen content in the skin as well as other dermatological parameters.
Essential oxygen oil(美国佛罗里达州那不勒斯的 CreoMed Inc. 的 OxyRub)是一种新型的局部镇痛药,目前在欧洲商业化销售,现在也可在美国使用。它是管理轻度至中度急性和慢性疼痛的其他治疗方法(非甾体抗炎药、对乙酰氨基酚、薄荷醇、樟脑)的重要替代方法。将对该油的几项临床试验进行回顾。
一项大型(n=455)开放性试验发现,Essential oxygen oil 是一种安全有效的镇痛药,适用于急性和慢性疼痛的广泛患者。在该研究中,80%的患者报告疼痛减轻了 75%以上。一项针对肌腱炎患者的双盲安慰剂对照研究(n=50)发现,Essential oxygen oil 可显著减轻患者的疼痛。另一项针对各种疼痛诊断的 Essential oxygen oil 与安慰剂的试验(n=50)发现,98%的各种疼痛诊断患者在使用 essential oxygen oil 的组中报告“非常好”的疼痛缓解,而安慰剂组为 48%。此外,一项在 10 名女性中测量皮肤中氧气微循环效应的随机对照试验显示,应用 essential oxygen oil 后皮肤的氧气微循环效应增加,氧合作用改善(皮肤中的氧分压增加)。在所有研究中,该油均耐受良好。这些研究均未发表。
根据已完成的研究,Essential oxygen oil 已被证明是安全的,对治疗急性和慢性疼痛具有积极的镇痛作用,并改善了皮肤中的氧气含量和其他皮肤科参数。
