Viagra Professional vs Sildenafil Citrate: are they the same?
Viagra Professional is a commercial brand whose active ingredient is exactly Sildenafil Citrate. This page explains what that means in practice: where they differ (brand, manufacturer, price, available strengths), why they are clinically equivalent, and when the brand or an authorised generic is the better choice.
Are they the same?
Yes — Viagra Professional contains Sildenafil Citrate as its active ingredient. Talking about "Viagra Professional" in clinical terms is the same as talking about Sildenafil Citrate at the dose strengths 100mg. The differences from the authorised generic are brand, manufacturer (Pfizer), excipients, tablet appearance and price — not the active molecule itself.
When Viagra Professional is used
バイアグラ プロフェッショナルは勃起不全のある成人男性を対象としています。女性、小児患者、または臨床診断のない男性には適応がありません。シルデナフィルの一般的な処方原則に従い、使用前に患者の心血管健康状態と現在の服薬リストを確認すべきです。100mg単一製剤は、忍容性の理由から通常はより低い開始用量を必要とする患者には適していません。
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: シルデナフィルクエン酸塩はPDE5を阻害し、性的興奮中に生成される環状GMPが陰茎組織に蓄積するようにし、これにより陰茎動脈の平滑筋が弛緩し血流流入が増加します。舌下経路は分子を口腔粘膜を通じて全身循環に直接送達し、肝初回通過代謝の一部を回避します。製品資料によれば、これにより通常錠の30~60分に対し作用発現を15~30分に短縮できます。
Brand or generic — which to choose?
For most patients, authorised generics of Sildenafil Citrate are clinically equivalent substitutes for Viagra Professional and typically cost substantially less. The practical differences are manufacturer, excipients (rarely matters except in specific sensitivities), tablet appearance and price. The brand is preferred by some patients for personal reasons or insurance coverage; the generic is the default when cost matters.
