Most of all generics are manufactured in the European Union countries and India. As for pharmacokinetics we can say that profiles of all generics, as a rule, are similar to the profiles of original molecule in terms of excretion; the number of adverse reactions is also approximately same and averaged from 10.9 to 17% and action time lasts for 4-5 hours. Indications as well as contraindications for Sildenafil-containing products are similar. It ought to be said that these days exists adapted for women Sildenafil (Eriacta). It was designed for use by women suffering from tough vaginal dryness, anorgasmia and other diseases. The only thing has to be mentioned that clinical response of the medicine was not proven so far. What interesting is that other generics are restricted to use in women. There are articles, in particular, for example, dedicated to Eriacta (Sildenafil), reporting about its positive effect on the qualitative profile of spermatozoa. It was found that in small doses this agent is really capable to boost the activity of spermatozoa of A + B categories, but when a dosage is more than 250 mg it causes a hyper inhibitory action. According to the histological study a long-term use of Sildenafil-containing remedies does not affect cells of seminiferous epithelium.

Also, a positive impact of the medicine on spermatogenesis was evidenced, and its price corresponds to other analogues.

Sildenafil (Eriacta) has been successfully used in the erectile dysfunction treatment in patients having different pathology in both mono- and combined therapy. It can be used in patients with various somatic diseases, and the conducted clinical trials results open new prospects for its application.
