The sentiment and conversation topics about Avandia over the past seven years have shown a dramatic change. Wool.labs has found a strong and unmistakable pattern in the timeline of conversations, sentiment and topics. Conversations in 2004 focused on the benefits of Avandia, and in 2005 patient concerns began to overshadow diabetes control. From 2006 until the present, conversation intensity and sentiment degraded as patient anger increased over concerns of heart problems and a lack of clear and understandable information from doctors, GSK or the FDA.
