The accessibility of prescription drugs produced outside of the United States, most notably sildenafil citrate (innovator product, Viagra®), has been made much easier by the Internet. Of greatest concern to clinicians and policymakers is product quality and patient safety. The US Food and Drug Administration (FDA) has issued warnings to potential buyers that the safety of drugs purchased from the Internet cannot be guaranteed, and may present a health risk to consumers from substandard products. The objective of this study was to determine whether generic sildenafil citrate tablets from international markets obtained via the Internet are equivalent to the US innovator product regarding major aspects of pharmaceutical quality: potency, accuracy of labeling, and presence and level of impurities. This will help identify aspects of drug quality that may impact public health risks.
Food Interactions
A total of 15 sildenafil citrate tablets were obtained for pharmaceutical analysis: 14 generic samples from international Internet pharmacy websites and the US innovator product. According to US Pharmacopeial guidelines, tablet samples were tested using high-performance liquid chromatography for potency of active pharmaceutical ingredient (API) and levels of impurities (impurities A, B, C, and D). Impurity levels were compared with International Conference on Harmonisation (ICH) limits. Among the 15 samples, 4 samples possessed higher impurity B levels than the ICH qualification threshold, 8 samples possessed higher impurity C levels than the ICH qualification threshold, and 4 samples possessed more than 1% impurity quantity of maximum daily dose (MDD). For API, 6 of the samples failed to fall within the 5% assay limit. ICH has developed guidelines for threshold of impurity quantity in new drug products [ICH, 2006], which are presented in Table 1. Per ICH guidelines, identification threshold is the limit above which a degradation product should be identified. Reporting threshold is the limit above which the degradation product should be reported to regulatory bodies.

Results suggest that manufacturing standards for sildenafil citrate generic drug products compared with the US innovator product are not equivalent with regards to potency and levels of impurities.

Is Vigora a prescription drug?
In fact, the pharmaceutical company Pfizer, who first brought Viagra to market in 1998, is setting up its own site to sell Viagra online, in what it says is an effort to curb the sale of counterfeit versions of the drug [Isidore, 2013]. Viagra was the first treatment for erectile dysfunction in an oral dosage form. Initially, it was studied for treatment of hypertension and angina pectoris, but early clinical trials suggested that although it had little effect on angina, it was observed to induce penile erections. As a result, Pfizer made the decision to market Viagra for erectile dysfunction [Ghofrani et al. What followed was an immediate healthcare, if not absolute, business success. If the impurity is unusually toxic, lower threshold values are appropriate. Maximum daily dose (MDD) is the maximum amount of drug administered per day.

According to reports at the time: ‘Within two weeks, newspapers reported physicians were writing 15,000 to 20,000 prescriptions a day for the medication’ [Rodriguez, 1998]. In the week of 8 May 1998, and 1 month after Viagra’s release, more than 300,000 total prescriptions were written for Viagra in the US, and Pfizer reported that more than US$400 million worth of Viagra was sold in the first quarter [Keith, 2000]. More recently, according to the healthcare consulting firm IMS Health, approximately 8 million prescriptions for Viagra were written in 2012, which translates into total sales of about US$2 billion. And of the ‘market share’ for pharmaceuticals for erectile dysfunction, which also includes Cialis, Levitra, and Staxyn [Drugs.com, 2014], Viagra has approximately 45% of the market, just ahead of Eli Lilly’s Cialis [Wilson, 2013]. As an illustration of the popularity of online sildenafil, an Internet search using the search terms ‘online sale Viagra’ resulted in over 1.5 million hits, directing the user to locations of Internet pharmacies selling generic versions of this product [Lowe and Costabile, 2011]. This study reports on the drug product variability of sildenafil. The objective of this study is to determine whether generic sildenafil tablets from international markets obtained via the Internet are comparable with the US innovator product with regard to major aspects of pharmaceutical quality: potency and accuracy of labeled amount, and level of impurities.

Email spam for Viagra is so pervasive that Microsoft and Pfizer jointly filed several lawsuits against pharmacy spam rings running sites that allegedly sell generic Viagra. Millions of disruptive email messages potentially lure consumers to those URLs selling illegal Viagra. According to some estimates, Viagra and other erectile dysfunction medicines or cures may account for as much as a quarter of all spam [Information Week, 2005]. An important key issue of Internet drug importation, and of considerable concern to clinicians and healthcare policymakers, is patient safety due to poor product quality. According to the US Food and Drug Administration, ‘FDA cannot ensure the safety and effectiveness of products that are not FDA-approved and come from unknown sources and foreign locations, or that may not have been manufactured under proper conditions.
