India has a large share of the hepatitis C virus (HCV) burden of the world. Unsafe medical practices and blood transfusions are the leading modes of transmission of HCV in India. The commonest HCV genotype in India is genotype 3 followed by genotype 1. While directly acting antivirals (DAAs) agents have become available at reasonable rates in India, cost of therapy remains a major barrier for control of HCV in India. Generic DAAs have been proven to be cost-saving in prior studies. We examined data from various studies in India and elsewhere using generic DAAs, and evaluated whether they are equally efficacious as the branded drugs. Since the availability of generic DAAs in the Indian market, there is a lot of real life data as well as prospective studies in special patient populations such as hematological disorders (thalassemia and hemophilia), chronic kidney disease, hemodialysis patients, post liver and renal transplant patients on immunosuppression, intravenous drug users, confections and other high risk groups. Control of HCV infection in India requires multi pronged approach. There is a need to formulate a health educational curriculum targeting not only the high-risk population but also the general population regarding the transmission of HCV. Adopting the dual approach of treating the old cases (decreasing the reservoir pool of HCV) and decreasing the incidence of new ones would help curtail the disease and decrease liver related mortality. In this scenario, the role of efficacious low cost generic medications is essential.
印度承担着全球很大一部分丙型肝炎病毒(HCV)负担。不安全的医疗行为和输血是印度HCV的主要传播方式。印度最常见的HCV基因型是3型,其次是1型。虽然直接作用抗病毒药物(DAAs)已在印度以合理价格上市,但治疗费用仍然是印度控制HCV的主要障碍。在先前的研究中,已证明仿制药型DAAs具有成本节约效果。我们研究了印度及其他地区使用仿制药型DAAs的各类研究数据,并评估它们是否与品牌药物具有同等疗效。自从仿制药型DAAs在印度市场上市以来,有大量来自现实生活的数据以及针对特殊患者群体的前瞻性研究,如血液系统疾病(地中海贫血和血友病)、慢性肾脏病、血液透析患者、肝和肾移植后接受免疫抑制治疗的患者、静脉吸毒者、糖果工人及其他高危人群。在印度控制HCV感染需要采取多管齐下的方法。有必要制定一个健康教育课程,不仅针对高危人群,也针对普通人群,内容涉及HCV的传播。采用治疗旧病例(减少HCV储存库)和降低新病例发病率的双重方法,将有助于控制该疾病并降低肝脏相关死亡率。在这种情况下,有效的低成本仿制药的作用至关重要。
