Drug advertisement brochures (DABs) contain claims that are often supplemented by references in medical literature. Several studies have evaluated the DABs as they are commonly distributed by drug companies to practicing physicians. The objective of this study is to assess the consistency between the claims and references referred to in the DABs in Saudi Arabia. DABs were collected from medical practitioners in Riyadh, Saudi Arabia. Authors developed a protocol to be followed for quality assessment of the DABs. The vast majority of cited scientific papers were indexed in PubMed. Consequently, each reference was categorized as: justifiable, false, exaggerated or ambiguous. A total of 89 DABs were collected; 48 (53.9%) brochures were excluded from further analysis and the remaining 41 brochures (46.1%) contained 240 references with an approximate average of 5.9 references per DAB. A total of 201 cited papers were traced (83.8%). The majority of references (93.0%) supported the claims for which they were cited. However, 1.5%, 4.0% and 1.5% of claims were deemed inaccurate/false, exaggerated, and ambiguous, respectively. This study supports that the majority of the claims made in the DABs of pharmaceutical companies in Saudi Arabia were unreferenced. However, most of the evidence presented to substantiate claims made was considered true.
