How it works
This product’s leaflet is published as a scanned document. This section quotes the US prescribing label for the same active substance (sildenafil citrate). It describes the substance, not this Bulgarian product — its uses and doses can differ.
The physiologic mechanism of erection of the penis involves release of nitric oxide (NO) in the corpus cavernosum during sexual stimulation.
NO then activates the enzyme guanylate cyclase, which results in increased levels of cyclic guanosine monophosphate (cGMP), producing smooth muscle relaxation in the corpus cavernosum and allowing inflow of blood.
It is eliminated predominantly by hepatic metabolism (mainly CYP3A4) and is converted to an active metabolite with properties similar to the parent, sildenafil.
After either oral or intravenous administration, sildenafil is excreted as metabolites predominantly in the feces (approximately 80% of administered oral dose) and to a lesser extent in the urine (approximately 13% of the administered oral dose).
When sildenafil is taken with a high fat meal, the rate of absorption is reduced, with a mean delay in T max of 60 minutes and a mean reduction in C max of 29%.

Safety of the active substance
This product’s leaflet is published as a scanned document. This section quotes the US prescribing label for the same active substance (sildenafil citrate). It describes the substance, not this Bulgarian product — its uses and doses can differ.
- Administration of sildenafil tablets to patients using nitric oxide donors, such as organic nitrates or organic nitrites in any form.
- After patients have taken sildenafil tablets, it is unknown when nitrates, if necessary, can be safely administered.
- Hypersensitivity reactions have been reported, including rash and urticaria [ see Adverse Reactions (6.1) ]. 4.3 Concomitant Guanylate Cyclase (GC) Stimulators Do not use sildenafil tablets in patients who are using a GC stimulator, such as riociguat.
- PDE5 inhibitors, including sildenafil, may potentiate the hypotensive effects of GC stimulators.
