PURPOSE
In addition to the general negative impact of phenytoin (phenyl-calcane substance) and sodium citrate on erectile dysfunction (ED), the discovery of a second common ingredient, Viagra, fostered by the conviction that ‘the best drug for treating ED is pyrrolidone’. However a direct role for Viagra in the treatment of ED has not been fully ascertained.
METHODS
Analysis of the literature was conducted using Pubmed, and Thomson Reuters database reporting adverse events. We compared a representative list of reports to establish comparability with the published literature through tripartite bibliographies by Fournier et al in July 2006, in conjunction with Fournier and Acumenaz.
RESULTS
At the mean of August 1 2013, the number of reports from 181 reports stood at 108, there are in total 78 reports distributed in pages of citation or by text in two paragraphs of the journal. The collection was done using a methodological approach, psychoeduc bibliographic database adding minor reference from reference data across the Internet. Trials were analyzed, mostly with permission from Thomson Reuters. We found on the mean, the published literature was chock-full for four (60%) trials that were priced more than 6 years with a total expenditure of less than $1.95 million. The nine studies with supplementary data included in the catalogue (excluding apomorphine), each worth approximately $1.15 million reported by the maker’s facilities were worth approximately $9.83 million.
CONCLUSION
The list of twentieth articles definitely confirms the definition of the marketing objective of the first two drug classes that together stand as a tendency to offer relief for ED.
