Local production of generic medicines in developing countries has a critical role to meet public health needs by ensuring the availability of essential medicines and providing patients' relief from the burden of unaffordable medical bills. Compliance with bioequivalence (BE) requirements increase the quality and competitiveness of generic drugs regardless of the source. In this regard, a regional BE center has been established in Addis Ababa, Ethiopia to serve the needs of Ethiopia and neighbouring countries. The present study aimed to assess the knowledge and perceptions of health professionals working in Addis Ababa regarding local production and BE studies of generic medicines. A cross-sectional survey was employed and physician participants working at public hospitals and pharmacists from various practice settings were selected using convenient sampling technique. Data was collected using self-administered structured questionnaire. Descriptive statistics was used to summarize the data and multinomial logistic regression analyses was used to assess predictors of health professionals' perception towards the source of drugs. Statistically significant association was declared at p-value < 0.05. A total of 416 participants responded and 272 (65.4%) of them were male. Nearly half of the study participants (n = 194) preferred the imported products. Compared to physicians, participants with diploma (AOR = 0.40; 95%CI: 0.18-0.91, p = 0.028) and bachelor degree and above holders (AOR = 0.32; 95%CI: 0.15-0.68, p = 0.003) in pharmacy were more likely to prefer locally produced products. Participants who practiced in pharmaceutical industries (AOR = 0.40, 95%CI: 0.22-0.77, p = 0.006) preferred locally manufactured products as compared to those practicing in the hospital. While a majority (321, 77.2%) believed in the advantages of doing BE studies locally, only 106 (25.5%) recognized that local pharmaceutical manufacturers did not implement BE studies for their generic products and lack of enforcement by the national regulatory body was raised as a reason for not conducting BE studies by most of the participants (67.9%). The present study revealed a modest preference by physicians and pharmacy professionals towards locally produced products. Majority of participants supported the idea of doing BE studies locally. However, manufacturers and regulators should devise ways to increase health professionals' confidence in local products. Strengthening local BE study capacity is also highly recommended.
发展中国家生产仿制药对于满足公共卫生需求具有重要作用,确保基本药物的供应,并减轻患者因无法负担医疗费用而带来的负担。无论来源如何,遵守生物等效性(BE)要求都能提高仿制药的质量和竞争力。为此,在埃塞俄比亚亚的斯亚贝巴建立了一个区域 BE 中心,以满足埃塞俄比亚和邻国的需求。本研究旨在评估在亚的斯亚贝巴工作的卫生专业人员对仿制药本地生产和 BE 研究的知识和看法。采用横断面调查,使用便利抽样技术选择在公立医院工作的医生和来自各种实践环境的药剂师。使用自我管理的结构化问卷收集数据。使用描述性统计方法总结数据,并使用多项逻辑回归分析评估卫生专业人员对药物来源看法的预测因素。p 值<0.05 表示具有统计学意义。共有 416 名参与者做出回应,其中 272 名(65.4%)为男性。近一半的研究参与者(n=194)更喜欢进口产品。与医生相比,持有文凭(AOR=0.40;95%CI:0.18-0.91,p=0.028)和学士及以上学位的参与者(AOR=0.32;95%CI:0.15-0.68,p=0.003)更倾向于选择本地生产的产品。与在医院工作的参与者相比,在制药行业工作的参与者(AOR=0.40,95%CI:0.22-0.77,p=0.006)更倾向于选择本地制造的产品。虽然大多数参与者(321 人,占 77.2%)认为在当地进行 BE 研究具有优势,但只有 106 人(25.5%)认识到本地制药商没有为其仿制药进行 BE 研究,并且国家监管机构缺乏执行力度,这也是大多数参与者(67.9%)不进行 BE 研究的原因。本研究表明,医生和药剂师对本地生产的产品有一定的偏好。大多数参与者支持在当地进行 BE 研究的想法。然而,制造商和监管机构应想办法增强卫生专业人员对本地产品的信心。此外,还强烈建议加强当地的 BE 研究能力。
