This paper assesses Patent Medicine Vendors' (PMVs) practices, awareness of new Nigerian Artemisinin Combination Therapy (ACT) policy, the anti-malarial drugs in stock and how the PMVs identify fake drugs.
PMVs and medicine shops were selected through a multi-stage random sampling process, beginning with the purposive selection of three states that reflect major geographic and ethnolinguistic areas of Nigeria: Oyo (Southwest-Yoruba), Kaduna (Northcentral-Hausa), and Enugu (Southeast-Igbo). Local Government Areas (LGAs) in selected states were stratified into urban and rural strata, with two LGAs randomly sampled from each stratum in each state, and one ward (urban LGAs) or community (rural LGAs) randomly sampled from a list in each LGA. A complete listing of PMVs and drug shops was constructed at each site, yielding 111 PMVs and 106 medicine shops. Out of this number, a total of 110 PMVs consented to be interviewed.
Some PMVs (43.1%) were aware of the 2005 government policy that changed the recommended first-line treatment for malaria from chloroquine (CQ) to ACT, but significant differences were found between states (p < 0.001). PMV shops stocked many brands of anti-malarial drugs (average 5.5 brands), with ACTs stocked in only 8.5% of the stores at a mean price of N504 ($4) per treatment, compared to sulfadoxine-pyrimethamine (92% of shops, mean price of N90 ($0.7) and even monotherapy artesunates (32% of shops, mean price of N39 ($0.3). The PMVs identify a drug not bearing the National Agency for Food & Drug Administration and Control (NAFDAC) identification number as being fake or counterfeit.
PMVs need to be a part of the strategy to change treatment to ACTs if there are to be meaningful changes in the anti-malarial drugs that Nigerians receive.
本文评估了成药小贩(PMV)的经营行为、对尼日利亚青蒿素联合疗法(ACT)新政策的知晓情况、所储备的抗疟药物以及成药小贩识别假药的方式。
通过多阶段随机抽样过程选取成药小贩和药店,首先有目的地选择三个反映尼日利亚主要地理和民族语言区域的州:奥约州(西南部 - 约鲁巴族)、卡杜纳州(中北部 - 豪萨族)和埃努古州(东南部 - 伊博族)。选定州的地方政府区域(LGA)分为城市和农村两层,每个州的每层随机抽取两个LGA,然后从每个LGA的列表中随机抽取一个城区(城市LGA)或社区(农村LGA)。在每个地点编制了成药小贩和药店的完整清单,得到111名成药小贩和106家药店。其中,共有110名成药小贩同意接受访谈。
一些成药小贩(43.1%)知晓2005年政府将疟疾一线推荐治疗药物从氯喹(CQ)改为ACT的政策,但各州之间存在显著差异(p < 0.001)。成药小贩店铺储备了许多品牌的抗疟药物(平均5.5个品牌),只有8.5%的店铺储备了ACT,每次治疗的平均价格为504尼日利亚奈拉(4美元),相比之下,磺胺多辛 - 乙胺嘧啶(92%的店铺有储备,平均价格为90尼日利亚奈拉(0.7美元)),甚至青蒿琥酯单药疗法(32%的店铺有储备,平均价格为39尼日利亚奈拉(0.3美元))。成药小贩将未带有国家食品药品监督管理局(NAFDAC)识别号的药物认定为假药。
如果要使尼日利亚人接受的抗疟药物有实质性改变,成药小贩需要成为将治疗改为ACTs策略的一部分。
