新的带状疱疹治疗剂:Famciclovir(Famvir)

7月28日诺华公司宣布,FDA已经批准其处方药Famvir(泛昔洛韦,famciclovir)片剂作为单日疗法用于免疫力正常的复发型生殖器疱疹(RGH)患者。Famvir可显著降低愈合时间,并减少症状。此外,FDA还批准Famvir作为单剂量疗法用于治疗免疫力正常的复发型口唇疱疹患者。

与其他抗病毒药物联合应用治疗HBV感染的也有报道。Kruger[155]报道用泛昔洛韦和α-2b干扰素联合治疗了1例患乙型肝炎相关性结节性多动脉炎的56岁男性患者,获得成功。Piqueras等[156]报道用泛昔洛韦+干扰素成功治疗1例慢性乙型肝炎患者的肝衰竭。Marques等[157]用泛昔洛韦加α干扰素对5例以前用干扰素治疗失败的成人慢性HBV感染者治疗了20周。治疗方法是:先用泛昔洛韦治疗4周,再加用α干扰素治疗12周,最后停用干扰素,继续使用泛昔洛韦治疗4周。结果有2例患者的HBV DNA阴转,肝功能和肝脏组织学改善。侯金林等[120]在拉米夫定和拉米夫定+泛昔洛韦治疗期间HBV动态改变的研究中也同样证实,联合治疗可提高拉米夫定的抗病毒疗效。

尽管对泛昔洛韦的研究早于拉米夫定,但近年来用其治疗乙型肝炎的报道远远低于拉米夫定。其原因主要是因为其抗HBV作用低于拉米夫定,且同样可诱导HBV多聚酶的YMDD耐药性变异,而治疗费用高于拉米夫定。

Seehofer等[72]对1988年-1998年间的179例肝移植后复发性HBV感染的治疗进行了回顾性的分析,比较了使用泛昔洛韦或拉米夫定+乙型肝炎免疫球蛋白治疗肝移植后复发性HBV感染的疗效,发现泛昔洛韦的疗效低于拉米夫定,且使用泛昔洛韦治疗后出现耐药的患者使用拉米夫定治疗仍然有效。Rayes等[10]对肝移植后长期应用泛昔洛韦和拉米夫定(20例)治疗乙型肝炎进行了比较性研究。32例患者使用泛昔洛韦治疗,20例患者使用拉米夫定治疗,7例患者在泛昔洛韦治疗失败后再用拉米夫定治疗。结果19例用泛昔洛韦治疗的患者和76%用拉米夫定治疗的患者HBV DNA阴转;用拉米夫定治疗的患者中有24%的患者HBsAg阴转,而用泛昔洛韦治疗的患者中无1例HBsAg阴转。对泛昔洛韦治疗失败的患者,拉米夫定治疗也是有效的。作者认为,拉米夫定的抗病毒效应比泛昔洛韦强。

 最近,Berenguer等[158]报道了6例肝移植后的HBV感染者(HBsAg阳性,HBV DNA阳性,其中4例HBeAg阳性)用泛昔洛韦500mg tid治疗了至少12个月。结果无1例患者完全有效。有3例患者的ALT接近正常,无1例患者出现抗-HBs或抗-HBe的血清转换。2例患者的HBV DNA阴转,1例下降,其余3例甚至比治疗前DNA水平升高。仅1例患者治疗后肝脏组织学改善。因此作者认为,单独应用泛昔洛韦治疗肝移植后的HBV感染疗效欠佳。

在泛昔洛韦的Ⅲ期临床实验中,证实泛昔洛韦是一种强有力的抗HBV药物,但同时也发现长期应用后同样可以导致HBV多聚酶的YMDD基序变异。动物试验结果还证实,HBV对拉米夫定与泛昔洛韦有交叉耐药性。Mutimer[43]证实,在对拉米夫定耐药的两种变异株中,M550V-L526M与泛昔洛韦有交叉耐药性,而M550I与泛昔洛韦无关。据Rayes等[10]报道,长期治疗的患者中拉米夫定的耐药率为55%,而泛昔洛韦为80%。

Famvir
Generic Name: famciclovir (fam SYE klo veer)
Brand Names: Famvir

What is Famvir?
Famvir is an antiviral drug. It slows the growth and spread of the herpes virus so that the body can fight off the infection. Famvir will not cure herpes, but it can lessen the symptoms of the infections.

Famvir is used to treat infections caused by herpes viruses. Illnesses caused by herpes viruses include genital herpes, cold sores, shingles, and chicken pox.

--------------------------------------------------------

Important information about Famvir
Take this medication for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated.

Treatment with Famvir should be started as soon as possible after the first appearance of symptoms (such as tingling, burning, blisters).

Herpes infections are contagious and you can infect other people, even while you are being treated with Famvir. Avoid letting infected areas come into contact with other people. Avoid touching an infected area and then touching your eyes. Wash your hands frequently to prevent passing the infection to others.

--------------------------------------------------------

Before taking Famvir
Do not take this medication if you are allergic to penciclovir (Denavir). Before taking this medication, tell your doctor if you have:
kidney disease;
galactose intolerance;
severe lactase deficiency; or
glucose-galactose malabsorption.

If you have any of these conditions, you may need a dose adjustment or special tests to safely take Famvir.

FDA pregnancy category B. This medication is not expected to be harmful to an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment. It is not known whether Famvir passes into breast milk, or if it could harm a nursing baby. Do not take this medication without telling your doctor if you are breast-feeding a baby. Do not give this medication to a child younger than 18 years old.

--------------------------------------------------------

How should I take Famvir?
Take this medication exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor.

Treatment with Famvir should be started as soon as possible after the first appearance of symptoms (such as tingling, burning, blisters).

Take each dose with a full glass of water. Drink plenty of water while you are taking this medication to keep your kidneys working properly.
Famvir can be taken with or without food. Taking Famvir with food may decrease stomach upset.

Take this medication for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated. Famvir will not treat a viral infection such as the common cold or flu.

Lesions caused by herpes viruses should be kept as clean and dry as possible. Wearing loose clothing may help to prevent irritation of the lesions.

Store this medication at room temperature away from moisture and heat.

--------------------------------------------------------

What happens if I miss a dose?
Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at the next regularly scheduled time. Do not take extra medicine to make up the missed dose.

--------------------------------------------------------

What happens if I overdose?
Seek emergency medical attention if you think you have used too much of this medicine. Symptoms of a Famvir overdose are unknown.

--------------------------------------------------------

What should I avoid while taking Famvir?
Herpes infections are contagious and you can infect other people, even while you are being treated with Famvir. Avoid letting infected areas come into contact with other people. Avoid touching an infected area and then touching your eyes. Wash your hands frequently to prevent passing the infection to others.

Famvir will not prevent the spread of genital herpes. Avoid sexual intercourse or use a latex condom to prevent spreading the virus to others.

--------------------------------------------------------

Famvir side effects
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
Less serious side effects may include:
nausea, vomiting, stomach pain;
headache;
diarrhea,
dizziness, sleepiness;
mild itching or skin rash; or
confusion.

This is not a complete list of side effects and others may occur. Tell your doctor about any unusual or bothersome side effect. You may report side effects to FDA at 1-800-FDA-1088.

--------------------------------------------------------

What other drugs will affect Famvir?
Before taking Famvir, tell your doctor if you are also taking probenecid (Benemid). If you are using probenecid, you may not be able to use Famvir, or you may need dosage adjustments or special tests during treatment.

This list is not complete and there may be other drugs that can interact with Famvir. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor.
