A Survey on Illegal and Counterfeit Medicines for the Treatment of Erectile Dysfunctions in Italy

Introduction In developed countries the phenomenon of pharmaceutical counterfeiting is steadily increasing through the illegal and the Internet market. Medicines for the treatment of erectile dysfunctions containing phosphodiesterase type 5 inhibitors (PDE5) are especially prone to falsification. Aims To obtain evidence of the health risks for patients taking these products and to provide useful information to general practitioners and specialists in sexual medicine. Methods First the samples were visually inspected and then analyzed to get information about their identity and quality. Main Outcome Measures A survey on the PDE5 medicines analyzed by the Italian official medicines control laboratory between 2005 and 2011 was performed. All the analyzed medicines were gathered from the Italian illegal market (seizures by police forces) or were bought from illegal online pharmacies. Results The study revealed that 24% of the analyzed samples were counterfeit and 54% were illegal medicines. In 12% of the cases an intermediate classification ( illegal/counterfeit ) was assigned. Only 7% of the samples were original. Moreover, the examination of the packaging evidenced potential risks: outer and immediate packaging missing; inconsistency between the carton box and the blister as regards the expiry date and/or the batch number; expiry date or manufacturer's name or country missing. Conclusions In 19% of the samples a potential health risk for patients was identified due to either the presence in the sample of more than one undeclared PDE5(s) or an amount of the active ingredient higher than that declared (up to 190% of the maximum dose) or to the presence of potentially dangerous excipients of non‐pharmaceutical origin or quality (e.g., gypsum or non‐purified talc).
