Sildenafil 100mg: pharmaceutical gradeViagra (Sildenafil) Research Areas
- Fast, defined window: Acts within about an hour, something you plan around
- Food delays absorption: A heavy meal noticeably slows onset
- Acts on blood flow, not desire: Arousal still has to happen for it to do anything
- Shorter tail than tadalafil: Out of the system considerably faster
How Viagra (Sildenafil) Works
Sildenafil blocks PDE5, the enzyme that breaks down cGMP. With cGMP persisting, smooth muscle stays relaxed and blood flow is maintained.
Like all PDE5 inhibitors it makes the response to arousal work properly, it does not create arousal.
Sildenafil vs Tadalafil
Sildenafil is short and sharp, and needs planning around food and timing. Tadalafil lasts up to 36 hours and is unaffected by meals, which suits spontaneity.
Worth naming: new erectile difficulty can be an early marker of cardiovascular disease, because the vessels involved are small and show problems first. It is worth investigating rather than only medicating.
