A Critical Analysis of Claims and Their Authenticity in Indian Drug Promotional Advertisements

Critical Appraisal of Drug Promotional Literature in Accordance With WHO Guidelines

Background

Drug promotional literature (DPL) is used as a marketing tactic to publicize the introduction of new medications. As drug companies are promoting the literature for their brand products, bias is possible. Various studies have demonstrated that printed DPLs disseminated by pharmaceutical companies are typically skewed.

Material and method

A prospective, observational study was carried out in the outpatient departments of a tertiary care hospital to analyze the DPL of different pharmaceutical companies using WHO criteria for "Ethical criteria for medicinal drug promotion, 1988".

Results

Out of 192 DPLs analyzed, information regarding the generic name, brand name, amount of active ingredient, and manufacturer name was found in all the DPLs (100%). Though therapeutic uses were mentioned in 91% of DPLs, dosage schedule (regimen) was mentioned only in 60%. Drug safety information such as the side effects and significant adverse drug reactions, precautions and warnings, contraindications, and major drug interactions were present in 24%, 36%, and 20%, respectively. Address of the manufacturer and reference to scientific literature were present only in 63% and 53% of DPLs, respectively. References mainly were from journals, present in 71% of DPLs. Most of the claims made in DPLs were regarding efficacy (73%), followed by safety (34%). 

Conclusion

In our study, not a single DPL fulfilled all the nine WHO criteria. A doctor should rigorously evaluate study findings before prescribing because misleading and incorrect information is now frequently found in this literature.

A study of perceptions and exposure of drug promotional literature among clinicians in a teaching hospital

BACKGROUND

Drug promotional literature (DPL) forms a major marketing technique of pharmaceutical companies for propagating information regarding a drug. Many a times, it is the only source on which treating physicians depend for updating their knowledge about the existing and novel drugs.

AIMS AND OBJECTIVES

This study was conducted to understand the clinicians' perceptions about DPL and its critical appraisal so that relevant interventions can be made.

MATERIALS AND METHODS

It was a cross-sectional questionnaire based study. A self-administered validated questionnaire was administered to 125 clinicians working in a medical college, which sought responses on their perception of various aspects including interpretation, analysis, evaluation, inference and decision making based on the DPL which they encounter in their day-to-day practices. The data was analyzed using descriptive statistics.

RESULTS

A total of 100 clinicians reciprocated with complete questionnaire. 99% of the clinicians were exposed to pharmaceutical promotional activities and around 79% clinicians accepted that drug promotion has a considerable bearing on their prescribing practices. Majority (79%) of the clinicians felt that the accuracy of the claims in the various forms of DPL was between 50-75%. Amongst the various forms of DPL, brochures were adjudged as the most useful followed by interactions with medical representatives, advertisements in medical journals and direct mailers. a majority of the clinicians (69%) felt that, though the claims in the DPL are balanced but are supported by poor evidence. Around 75% clinicians perceived the primary intention of drug promotional literature was to boost company sales. Around 84% clinicians felt that doctors' integrity can be compromised by accepting gifts from medical representatives. Over 75% of clinicians believed that training in interacting with medical representatives and assessing other forms of drug promotional literature should be imparted to undergraduates in medical colleges.

CONCLUSION

Physicians need to be aware that the pharmaceutical industry may use drug advertisements to influence prescription patterns even when this results in distortion of scientific facts. The pharmaceutical industry should be more responsible and more meticulous in making sure that pharmaceutical claims referring to scientific studies are quoted accurately.

Assessment of a Pharmaceutical Advertisement Analysis Module in a Drug Literature Evaluation Course

Objective. To evaluate the impact of an educational module on students' self-efficacy when analyzing the content of promotional drug brochures (PDBs) and to assess the students' value of PDBs' as an educational tool. Methods. Third-year bachelor of pharmacy students participated in a one-hour lecture and a two-hour laboratory. Students completed a survey before and after participating in the module. Results. The module elicited a statistically significant change in students' self-efficacy beliefs regarding evaluating promotional drug brochures, while the average perceived value of promotional drug brochures did not change significantly after the module. Conclusion. A brief educational module can increase students' self-efficacy in evaluating the content of PDBs.
