ABSTRACT
Background: Drug promotional literature (DPL) is used by the pharmaceutical companies for promotion of their drug. It is the commonest source for providing information about the drug to the physician. According to WHO promotional literature should be reliable, truthful, informative, balanced and up to date.Methods: Study was conducted in Department of Pharmacology, Muzaffarnagar Medical College. 200 drug promotional literatures like advertisements published in medical journal, package insert of medicinal products and brochures were collected and analysed according to WHO criteria.Results: Total 200 promotional literatures were analysed. 100 promotional literatures were from the medical journal, 50 were package inserts of medicinal products and 50 were medicinal brochures. On assessing DPL using WHO criteria, all DPL mentioned brand names and dosage form (100%). Most of them published the generic name (98.5%), therapeutic uses (78%), side- effects (75%), dosage regimen (70%), contraindication (62.5%), warnings (55%), drug interaction (54%), precaution (50%), reference to scientific literature (45%), name of manufacture and distributor (99%), address of manufacturer and distributor (50%). Out of 200 DPL only 151 DPL contain references to scientific literature, 88 DPL references were retrievable and 63 were non retrievable.Conclusions: Our study shows although pharmaceutical companies are trying to adhere to the WHO criteria it is not fulfilled. As DPL are an important source of seeking information by the medical practitioner who rely on them to impart treatment to the patient, strict steps to regulate fulfilment of the WHO criteria should be taken by the government and authorities.
ABSTRACT
Background: The study was aimed to critically analyse Drug Promotional Literatures (DPLs) using WHO guidelines. This would help to create awareness about DPLs amongst healthcare providers thus encouraging the improvement of healthcare system.Methods: This cross sectional observational study was carried out at Department of Pharmacology, Medical College Baroda. DPLs were collected & critically analysed for consistency, accuracy, validity of the provided information as per WHO guidelines.Results: Out of total 616 DPLs collected, 371 satisfied the inclusion criteria. None of the DPL was fulfilling all criteria according to WHO guidelines. Most of DPLs were having information regarding; generic name / INN (98.39%), brand name (100%), amount of active ingredient per dosage (94.07%), approved therapeutic uses (84.91%), dosage form (91.37%) and name & address of manufacturers (91.91%). Of all the DPLs, information provided for safety parameters like; name of active ingredient known to cause problem (11.59%), dosage regimen (32.88%), side effects & drug reaction (14.56%), major drug interactions (14.02%) and precautions, contraindications and warning (14.29%) seemed to be grossly neglected. Total of 431 claims were evaluated, of which the most common type of claim was efficacy (55.45%). Relevant references to claims were present in (48.74%) DPLs. Total 203 references were evaluated from 371 DPLs, of which maximum reference were from journal article (74.38%).Conclusions: From this study, it was concluded that pharmaceutical companies didn’t follow the WHO guidelines for ethical drug promotion, thus failing to fulfil the rational promotion of drugs. Given the present findings physicians should be cautious about drawing conclusions regarding medicine based on DPLs provided by pharmaceutical companies.
ABSTRACT
Background: Drug promotional literature (DPLs) is an integral part of pharmaceutical marketing strategy. This marketing approach influences, a physician to prescribe definite variety of medicine from a particular company. Many physicians bank on exclusively in DPLs. This research was intended to appraise the DPLs available in Bangladesh for accuracy, consistency, and validity of the information in accordance with the WHO rules and regulations. Materials and Methods: This was a cross-sectional study was conducted in Uttara Adhunik Medical College, Dhaka, Bangladesh after collecting DPLs from the different outpatient department. The data was analyzed Microsoft Excel 2016. Results: None of the national and multinational DPLs fulfilled all the WHO criteria. Among the national and multinational DPLs, 94.7% and 100% presented with claims respectively. Out of 284 national and multinational DPLs references citation were presented in 82.04% and 100% respectively. Among the DPLs of national and multinational companies' relevant, irrelevant, and partially relevant pictures were presented in 48.79%, 24.65%, 26.76% and 31.58%, 26.32%, and 42.11%, respectively. Conclusion: DPLs of Bangladesh did not comply with the WHO guidelines while promoting their products. Evidence provided in those DPLs were mostly biased and persuasive since it is focusing mainly on the positive aspect of drug therapy. Accordingly, studied DPLs were principally aiming to maximizes industries' financial benefit rather than fulfill the educational aspects. The Government of Bangladesh should develop very stringent policy and practices regarding DPLs based on science and the WHO guideline as the literature very often act as a primary source of information among medical doctors.
