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 (vardenafil hydrochloride). It describes the substance, not this Bulgarian product — its uses and doses can differ.
Penile erection is a hemodynamic process initiated by the relaxation of smooth muscle in the corpus cavernosum and its associated arterioles.
During sexual stimulation, nitric oxide is released from nerve endings and endothelial cells in the corpus cavernosum.
Vardenafil is metabolized predominantly by the hepatic enzyme CYP3A4, with contribution from the CYP3A5 and CYP2C isoforms.
After oral administration, vardenafil is excreted as metabolites predominantly in the feces (approximately 91-95% of administered oral dose) and to a lesser extent in the urine (approximately 2-6% of administered oral dose).
Two food-effect studies were conducted which showed that high- fat meals caused a reduction in C max by 18%-50%.

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 (vardenafil hydrochloride). It describes the substance, not this Bulgarian product — its uses and doses can differ.
- Administration with nitrates and nitric oxide donors ( 2.4, 4.1 ) Administration with guanylate cyclase (GC) stimulators, such as riociguat ( 2.4, 4.2 ) 4.1 Nitrates Administration of vardenafil hydrochloride tablets with nitrates (either regularly and/or intermittently) and nitric oxide donors is contraindicated [see Clinical Pharmacology (12.2) ].
- Consistent with the effects of PDE5 inhibition on the nitric oxide/cyclic guanosine monophosphate pathway, PDE5 inhibitors, including vardenafil hydrochloride tablets, may potentiate the hypotensive effects of nitrates.
- A suitable time interval following dosing of vardenafil hydrochloride tablets for the safe administration of nitrates or nitric oxide donors has not been determined. 4.2 Guanylate Cyclase (GC) Stimulators Do not use vardenafil hydrochloride tablets in patients who are using a GC stimulator, such as riociguat.
- PDE5 inhibitors, including vardenafil hydrochloride tablets may potentiate the hypotensive effects of GC stimulators.
