Introduction
• Wikipedia is a top source of information around medical products for patients, the public and health care professionals
• The goal is to analyse the Wikipedia pages of the Top 20 pharmaceutical products
• Note: all analytics data sourced directly from Wikipedia (all statistics up to 20/3/14)– English language Wikipedia only

Hopefully a useful reference. Average daily views of 700. There appears no correlation between the size of the brand and daily views. This is to be expected, particularly considering the list is based on sales. This won’t equate to patient numbers due to price differences
Mood disorders, psychosis and chronic pain do seem to attract more interest. Seroquel is ranked 44 and has almost 2400 daily views

Many of these pages are very dynamic, being updated by the Wikipedia community weekly or more. Oxycontin as well as being the most viewed is the most edited

When the brands are ranked by daily page views there is a reasonable correlation with how often they are edited

More of a sense check and a reference. As expected the number of editors correlates well with the number of edits

• These guys have over 50 edits to their name for only one brand
• A detailed analysis has not been made of these users however their talk pages are often negative to Pharma. Their interests are clearly less broad when it comes to medicine. Do not appear to be involved in Wikipedia working groups related to medicine

Anypodetos
10
Interests in pharmacology and appears to be a pharmacist. Numerous edits small and large, that appear objective and well researched via the literature. Member of interesting Wikipedia pharmacology project team wp:pharm
Arcadian
9
Member of Neuroscience and Molecular & Cellular biology Wikiprojects. Over 130,000 article edits. Appears to be a physician and a Wikipedia administrator. Active on their talk page with balanced responses
Jmh649
9
Doc James, prominent Wikipedia physician contributing to multiple medicinal Wikiproject groups. Appears (understandably!?) skeptical on how neutral pharma companies can be when it comes to editing Wikipedia. Open for discussion on Wikipedia, will challenge but helpful
Beetstra7
Special interest in chemistry. Appears open to discussion. Edits appear minor and related to the chemistry elements of the page
Nbauman
6
Member of various Wiki-medical groups. Is not a doctor, rather their goal is to ensure articles are non-technical / jargon laden and suitable for the lay person. Appears well researched and open to expert input. Having said that made an edit to Aripiprazole on potential overuse citing the NY times
Key Learnings
• Brand page views vary but are typically seen around 1000 times per day
• There are a lot of editors yet a small number have a big influence
• Several editors have a significant influence over multiple brands
• The editors who have edited multiple brands appear more neutral and open to constructive debate
• Certain medications such as antidepressants / antipsychotics attract a lot more interest
