Silvitra works by inhibiting an enzyme called phosphodiesterase type 5 (PDE5) in the body. PDE5 breaks down a molecule called cyclic guanosine monophosphate (cGMP), which is crucial for controlling blood flow to the penis. Here’s how it works in more detail:
- Sexual Stimulation: During sexual arousal, the body releases nitric oxide (NO) in the penile tissues.
- Release of cGMP: Nitric oxide stimulates an enzyme that increases the levels of cGMP, a molecule that relaxes the smooth muscles in the blood vessels of the penis. This relaxation allows the blood vessels to widen, increasing blood flow into the penile tissues, which causes an erection.
- Inhibition of PDE5: Normally, PDE5 breaks down cGMP, ending the erection. The active ingredients, sildenafil and vardenafil, inhibit PDE5, allowing cGMP levels to remain elevated. It prolongs smooth muscle relaxation and maintains the increased blood flow needed for an erection.
- Sustained Erection: With PDE5 inhibited, cGMP levels stay high as long as there is sexual arousal, allowing for a sustained erection that enables sexual activity.
It is worth noting that Silvitra only works with sexual stimulation; it does not produce an erection on its own. Additionally, since Silvitra contains two PDE5 inhibitors, it may be more potent, and users should be cautious with the dosage to avoid increased risk of side effects.
