Synopsis

During the last years de Dutch market has been flooded with falsifications of Viagra. and Cialis.. Both products are used for the treatment of erectile dysfunction. This report is about the trend of these falsifications during the years 2000 - 2004. The risks of these products to public health are surveyed and also described. The following conclusions are drawn: There is a trend towards products containing other active compounds than sildenafil and tadalafil, the compounds of Viagra. and Cialis.. There is a trend towards the addition of (unknown) active compounds to herbal products. Falsifications are a risk to public health: they are produced without adequate quality control; they mislead the users concerning manufacturer and composition. The risk to public health is much higher if unknown, chemical compounds are added to herbal products. The effects and side effects of these compounds are unknown. Besides, herbal products are often considered to be natural and therefore harmless. In order to detect trends and new risks in the future, an ongoing survey of the legal and illegal market by analysing samples is needed. The trend analysis and risk survey are based on the analytical results of about 400 samples. These samples were sent in by governmental inspectorates for chemical analysis. The samples give an insight into the developments of the illegal market. However, they may not be representative for the market supply.
