A double blind, randomised, crossover placebo controlled trial of 5% acyclovir cream, applied topically five times a day for five days, was carried out in 45 patients with recurrent herpes labialis. These patients had a total of 72 episodes, 34 of which were treated with the 5% acyclovir cream and 38 with placebo cream. Treatment was begun by the patients as soon as possible after the onset of prodromal symptoms. There was no significant clinical benefit from treatment with acyclovir cream compared with placebo cream. The median healing times were nine days with acyclovir cream, 10 days with placebo cream, and 13 days when no treatment was given. The possibility that the 40% propylene glycol cream base alone has a therapeutic effect must therefore be considered.
对45例复发性唇疱疹患者进行了一项双盲、随机、交叉安慰剂对照试验,使用5%阿昔洛韦乳膏,每天局部涂抹5次,共5天。这些患者共有72次发作,其中34次用5%阿昔洛韦乳膏治疗,38次用安慰剂乳膏治疗。患者在前驱症状出现后尽快开始治疗。与安慰剂乳膏相比,阿昔洛韦乳膏治疗无显著临床益处。使用阿昔洛韦乳膏的中位愈合时间为9天,使用安慰剂乳膏为10天,未治疗时为13天。因此,必须考虑仅40%丙二醇乳膏基质本身具有治疗作用的可能性。
