Antiretrovirals are available at low prices in sub-Saharan Africa, but these prices may not be consistently available for middle-income countries in other regions with large HIV epidemics. Over 30% of HIV infected people live in countries outside sub-Saharan Africa. Several key antiretrovirals are still on patent, with generic production restricted. We assessed price variations for key antiretroviral drugs inside versus outside sub-Saharan Africa.
HIV drug prices used in national programmes (2010-2014) were extracted from the WHO Global Price Reporting Mechanism database for all reporting middle-income countries as classified by the World Bank. Treatment costs (branded and generic) were compared for countries inside sub-Saharan Africa versus those outside. Five key second-line antiretrovirals were analysed: abacavir, atazanavir, darunavir, lopinavir/ritonavir, raltegravir.
Prices of branded antiretrovirals were significantly higher outside sub-Saharan Africa (p<0.001, adjusted for year of purchase) (see Table 1). For example, the median (interquartile range) price of darunavir from Janssen was $732 (IQR $732-806) per person-year in sub-Saharan Africa versus $4689 (IQR $4075-5717) in non-African middle-income countries, an increase of 541%. However, when supplied by generic companies, most antiretrovirals were similarly priced between countries in sub-Saharan Africa and other regions.
Pharmaceutical companies are selling antiretrovirals to non-African middle-income countries at prices 74-541% higher than African countries with similar gross national incomes. However, generic companies are selling most of these drugs at similar prices across regions. Mechanisms to ensure fair pricing for patented antiretrovirals across both African and non-African middle-income countries need to be improved, to ensure sustainable treatment access.
抗逆转录病毒药物在撒哈拉以南非洲地区价格低廉,但对于其他地区有大量艾滋病毒疫情的中等收入国家而言,这些价格可能并非始终可得。超过30%的艾滋病毒感染者生活在撒哈拉以南非洲以外的国家。几种关键的抗逆转录病毒药物仍在专利保护期内,仿制药生产受到限制。我们评估了撒哈拉以南非洲地区内外关键抗逆转录病毒药物的价格差异。
从世界银行分类的所有报告中等收入国家的世界卫生组织全球价格报告机制数据库中提取国家项目(2010 - 2014年)中使用的艾滋病毒药物价格。比较了撒哈拉以南非洲地区内国家与地区外国家的治疗成本(品牌药和仿制药)。分析了五种关键的二线抗逆转录病毒药物:阿巴卡韦、阿扎那韦、达芦那韦、洛匹那韦/利托那韦、拉替拉韦。
撒哈拉以南非洲地区以外,品牌抗逆转录病毒药物价格显著更高(p<0.001,根据购买年份调整)(见表1)。例如,扬森公司的达芦那韦在撒哈拉以南非洲地区的人均年中位价格(四分位间距)为732美元(四分位间距732 - 806美元),而在非洲以外的中等收入国家为4689美元(四分位间距4075 - 5717美元),增长了541%。然而,当由仿制药公司供应时,大多数抗逆转录病毒药物在撒哈拉以南非洲地区国家和其他地区国家之间价格相似。
制药公司向非洲以外的中等收入国家销售抗逆转录病毒药物的价格比国民总收入相似的非洲国家高出74% - 541%。然而,仿制药公司在各地区销售这些药物的价格大多相似。需要改进确保非洲和非洲以外中等收入国家专利抗逆转录病毒药物公平定价的机制,以确保可持续的治疗可及性。
