Active ingredient of Levitra
Levitra contains vardenafil as an active ingredient. "Levitra 20 mg" means that it contains vardenafil hydrochloride hydrate 23.705 mg as active ingredient 20 mg as vardenafil.
This vardenafil hydrochloride hydrate is a white to slightly yellowish crystalline powder and has a slightly soluble property in ethanol (99.5) or water. This water soluble property is unique to Levitra not found in Viagra and Cialis. Therefore, the time to reach the maximum blood concentration is also 0.7 - 0.9 hours (42 minutes - 54 minutes), the earliest among 3 drugs of ED.
Levitra's effects and efficacy
Erection occurs when NO (nitric oxide) is released by receiving sexual stimulation / excitement, and substances that extend blood vessels such as cGMP (cyclic guanosine-phosphate) in the local cells increase. And the released cGMP is destroyed by enzymes called PDE 5 (phosphodiesterase type 5), whereby blood vessels of the corpus cavernosum contract and the erection subsides.
Levitra has an effect of suppression (suppression) of PDE 5 that breaks cGMP necessary for sustaining erection, so it has the effect of erection assistance.
The point is that Levitra is not a medicine to erect if you take it. After being sexually stimulated and sexually excited, it is a medicine that will assist you when you erect. As explained above, please understand that you first need to increase your own cGMP by sexual stimulation.
