英文药名: Norvir(Ritonavir oral solution)

中文药名: 利托那韦口服液

品牌药生产厂家: Abbott

药品简介

雅培公司的利托那韦片获得美国FDA批准上市,用于单独或与抗逆转录病毒的核苷类药物合用治疗晚期或非进行性的艾滋病病人。
利托那韦为人免疫缺陷病毒-1(HIV-1)和人免疫缺陷病毒-2(HIV-2)天冬氨酸蛋白酶的口服有效抑制剂,阻断该酶促使产生形态学上成熟HIV颗粒所需的聚蛋白,使HIV颗粒因而保持在未成熟的状态,从而减慢HIV在细胞中的蔓延,以防止新一轮感染的发生和延迟疾病的发展。本品对齐多夫定敏感的和齐多夫定与沙喹那韦耐药的HIV株一般均有效。
利托那韦的剂量为600mg每日2次口服,可与进食同时进行。剂量从300mg每日2次在5天内逐渐递增至600mg每日2次,可减少腹泻的发生, 而这是一种主要的副作用。口服液如在30天内仍未服完必须放入冰箱。与吲哚那韦的交叉耐药常见;对其他蛋白酶抑制剂部分或完全耐药亦可见到。利托那韦是最强的细胞色素P-450酶抑制剂, 其他药物如某些非镇静类抗组胺药(如特非那定), 镇静类催眠药(如咪哒唑仑), 或抗心律失常药与之合用会使这些药物浓度升高达中毒水平及致病。所有合并用药都必须考虑其与利托那韦的可能的相互作用。促进P-450的药, 如利福平, 会降低利托那韦的血浓度, 而得不到预期疗效。副作用包括腹泻, 口周感觉异常, 味觉改变, 恶心, 肝炎和脂类异常。

What should I watch for while taking ritonavir?

Visit your prescriber or health care professional for regular checks on your progress. Discuss any new symptoms with your prescriber or health care professional.

Ritonavir will not cure HIV and you can still get other illnesses or complications associated with your disease. Taking ritonavir does not reduce the risk of passing HIV infection to others through sexual or blood contact. It is best to avoid sexual contact so that you do not spread the disease to others. For any sexual contact, use a condom. Be careful about cuts, abrasions and other possible sources of blood contact. Never share a needle or syringe with anyone.

Ritonavir may cause abnormal liver function tests, changes in your cholesterol or triglyceride levels, and may increase the level of your blood sugar. Visit your health care professional or prescriber regularly to check for any of these side effects. Some of these effects may become serious.

If you are a woman of childbearing age and are using hormone contraceptives, then you should use another form of birth control while taking ritonavir. Ritonavir may decrease the effectiveness of hormone birth control agents, including birth control pills and injections.

What side effects might I notice from taking ritonavir?

Side effects of ritonavir may be temporary and decrease after 2 weeks of treatment. Try to stay on ritonavir for at least 2 weeks. When you start taking ritonavir, your prescriber may slowly increase your dose to minimize the potential side effects.
Side effects that you should report to your prescriber or health care professional as soon as possible:
• signs of a severe allergic reaction including difficulty breathing, tightness in throat, or swelling of your tongue
• increases in your blood sugar
• redness, blistering, peeling or loosening of the skin, including inside the mouth
• severe dizziness
• skin rash, hives
• unusual tiredness or weakness
• vomiting
• yellow color of eyes or skin

Side effects that usually do not require medical attention (report to your prescriber or health care professional if they continue or are bothersome):
• changes in taste
• diarrhea
• difficulty sleeping
• dizziness
• headache
• heartburn
• loss of appetite
• nausea
• stomach pain
• tingling or numbness in the hands or feet or around the mouth
• tiredness or weakness

Where can I keep my medicine?

Keep out of the reach of children in a container that small children cannot open.

Store the capsules in the refrigerator between 2 and 8 degrees C (36 and 46 degrees F). You do not need to keep them in the refrigerator if you use them all within 30 days and keep them below 77 degrees F. Do not expose the capsules to very hot or cold temperatures. Keep the container tightly closed. Throw away any unused medicine after the expiration date.
