Viagra Professional contains sildenafil citrate 100mg — the same active ingredient as standard Viagra — but in a sublingual formulation designed to dissolve under the tongue. This route of administration allows direct absorption through the sublingual mucosa, partially bypassing first-pass hepatic metabolism. The result is an onset of action of 15–20 minutes, compared to 30–60 minutes for a conventional oral tablet. Discreet delivery across Spain in 4–7 days.
What «Professional» Really Means — The Difference Nobody Explains
The name «Professional» does not indicate a higher dose or greater potency. The sildenafil dose is exactly the same: 100mg. The term refers to the sublingual formulation — a tablet designed to be placed under the tongue and dissolve in contact with saliva, rather than being swallowed whole.
The distinction matters because it completely changes the pharmacokinetics:
- A standard oral tablet must dissolve in the stomach and be absorbed through the small intestine before reaching the bloodstream — a process that takes 30–60 minutes and can be delayed by a further 60 minutes by fatty meals
- A sublingual tablet is partially absorbed through the dense venous capillary network under the tongue — a more direct route that significantly reduces absorption time and is less sensitive to stomach contents
Why the Sublingual Route Acts Faster — Pharmacology
The sublingual mucosa has unique anatomical features that make it ideal for rapid drug absorption: it is thin, highly vascularised and drains directly into the superior vena cava without passing through the hepatic portal system. This means sublingual sildenafil reaches systemic circulation faster and in a higher proportion than gastrointestinally absorbed sildenafil.
The practical effect: with Viagra Professional placed correctly under the tongue for 30–60 seconds before swallowing, the onset of action can occur within 15 to 20 minutes — approximately twice as fast as with the standard tablet.
Correct sublingual administration technique:
- Place the tablet directly under the tongue — not on top of it or between the cheek and gum
- Hold it there for 30–60 seconds while it dissolves in contact with saliva
- Allow the resulting liquid to remain in the mouth a few more seconds before swallowing
- Any residue not absorbed sublingually is swallowed and absorbed gastrointestinally — contributing the rest of the dose

Dosage and How to Take
- Dose: 1 tablet of 100mg per use — do not exceed this dose
- When to take: 15–20 minutes before sexual activity (thanks to sublingual route)
- How to take: Place under the tongue, hold for 30–60 seconds and allow to dissolve. Do not chew or swallow directly
- With meals: Can be taken with a light meal without significant loss of efficacy. Avoid very fatty and heavy meals
- Maximum frequency: 1 tablet per 24 hours
- Alcohol: Maximum 1–2 drinks. Excess reduces efficacy and increases risk of hypotension

Frequently Asked Questions
Does Viagra Professional contain more sildenafil than standard Viagra? No — the dose is exactly the same: 100mg. The difference is the sublingual formulation, which allows faster absorption, not a higher dose.
Can I swallow the tablet directly instead of placing it under my tongue? Yes, the tablet can be swallowed, but you will lose the advantage of rapid sublingual absorption. The onset of action would then be 30–60 minutes, the same as a standard tablet.
Viagra Professional or Kamagra Oral Jelly — which is faster? The onset speed is similar (15–20 min for both). Kamagra Jelly may be marginally faster in some cases and has the advantage of flavour. Viagra Professional is more discreet in format and does not require opening a sachet.
Can I take Viagra Professional with a light dinner? Yes — the sublingual route significantly reduces the influence of food on absorption. A light dinner does not significantly affect the onset of effect. Only very fatty and heavy meals may slightly delay the effect.
