Abstract
The efficacy of the different registered drugs has been compared against placebo. Observational and head-to-head studies have shown controverted results in the degree of efficacy between the products. Despite the efficacy reported, a high proportion of patients will have a lack of response to treatment. Early identification of these patients is therefore essential in order to attempt other therapeutic approaches.
