Direct to physician advertisements and direct to consumer advertisement (DTCA) is a well-known marketing strategy of pharmaceutical companies. Studies from the West and also from the Indian sub-continent revealed several lacunae in such advertisements.
The present study was carried out to understand the international and national scenario regarding the lacunae in drug advertisements and the opinion of both physicians and patients regarding DTCA.
The present study was conducted after obtaining approval from the institutional ethics committee. Warning letters (WLs) issued to pharmaceutical companies by United States Food and Drug Administration (USFDA) and Therapeutic Goods Administration (TGA) due to discrepancies in the advertisements were analyzed for reasons that were grouped into one of the following categories: overstatement of efficacy; unapproved indication; lack of adequate directions to use; omission of adverse effects; misleading claims; advertisement made for an unapproved drug (investigational new product). Drug advertisements in Current Index of Medical Specialties (CIMS) April-July 2014 issue was also analyzed for lacunae depending on categories as mentioned above. Physicians and patients in a tertiary care medical college and hospital were administered a validated questionnaire exploring their views about crucial aspects of DTCA. Descriptive statistics was used for each of the categories.
A total of 93 WLs issued by USFDA and 36 by TGA were assessed. Majority of the WLs by USFDA were issued for omission of adverse effects (61/93, 65.6%) followed by misleading claims (54/93, 58.1%). Similarly, WLs by TGA were also mainly issued for the presence of misleading claims (35/36, 97.2%) followed by overstatement of efficacy (26/36, 72.2%) and CIMS evaluation had revealed that 78/92 (84.8%) advertisements omitted adverse effects, 20/92 (21.7%) had misleading claims, 9/92 (9.8%) had unapproved indications and 7/92 (7.6%) overstated the efficacy. With regard to the opinion regarding DTCA, 69.9% physicians had a patient discussing DTCA that was clinically inappropriate. One hundred (64.5%) out of 155 physicians opined that DTCA encourage patients to attend physicians regarding preventive healthcare. On the contrary, 82/155 (52.9%) physicians felt that DTCA would damage the same. Similarly, 69 out of the total 100 patients felt that drug advertisements aid them to have better discussions with their treating physicians. Surprisingly, a large majority (91/100) were of the opinion that only safe drugs are allowed to be advertised.
To conclude, from the findings of this study both the physicians and patients should be cautious and not overzealous while dealing with drug advertisements or promotional literature. More stringent scrutiny and issue of WLs or blacklisting of indulging pharmaceutical companies are mandatory by the regulatory agency to contain the same.
直接面向医生的广告和直接面向消费者的广告(DTCA)是制药公司广为人知的营销策略。来自西方以及印度次大陆的研究揭示了此类广告存在的若干缺陷。
开展本研究以了解药物广告缺陷的国际和国内情况,以及医生和患者对DTCA的看法。
本研究在获得机构伦理委员会批准后进行。分析了美国食品药品监督管理局(USFDA)和治疗用品管理局(TGA)因广告存在差异而向制药公司发出的警告信(WLs),原因分为以下类别之一:疗效夸大;未批准的适应症;缺乏充分的使用说明;遗漏不良反应;误导性声明;为未批准药物(研究性新药)做广告。还根据上述类别分析了《医学专业当前索引》(CIMS)2014年4月至7月期的药物广告中的缺陷。对一所三级医疗学院和医院的医生和患者进行了一份经过验证的问卷调查,以探究他们对DTCA关键方面的看法。对每个类别使用描述性统计。
共评估了USFDA发出的93封WLs和TGA发出的36封WLs。USFDA发出的大多数WLs是因为遗漏不良反应(61/93,65.6%),其次是误导性声明(54/93,58.1%)。同样,TGA发出的WLs也主要是因为存在误导性声明(35/36,97.2%),其次是疗效夸大(26/36,72.2%),CIMS评估显示78/92(84.8%)的广告遗漏了不良反应,20/92(21.7%)有误导性声明,9/92(9.8%)有未批准的适应症,7/92(7.6%)夸大了疗效。关于对DTCA的看法,69.9%的医生有过与患者讨论临床上不合适的DTCA的经历。155名医生中有100名(64.5%)认为DTCA鼓励患者就预防性医疗保健咨询医生。相反,82/155(52.9%)的医生认为DTCA会对此造成损害。同样,100名患者中有69名认为药物广告有助于他们与主治医生进行更好的沟通。令人惊讶的是,绝大多数(91/100)人认为只有安全的药物才允许做广告。
总之,从本研究结果来看,医生和患者在处理药物广告或促销资料时都应谨慎,不要过于热心。监管机构必须进行更严格的审查并发出WLs或对违规制药公司进行黑名单处理,以控制这种情况。
