Levitra vs Vardenafil: are they the same?
Levitra is a commercial brand whose active ingredient is exactly Vardenafil. 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 — Levitra contains Vardenafil as its active ingredient. Talking about "Levitra" in clinical terms is the same as talking about Vardenafil at the dose strengths 5mg, 10mg, 20mg. The differences from the authorised generic are brand, manufacturer (Bayer), excipients, tablet appearance and price — not the active molecule itself.
When Levitra is used
レビトラは成人男性の勃起不全治療に適応されます。前立腺肥大症、肺動脈性肺高血圧症、女性、小児患者、または勃起不全と診断されていない男性への使用は承認されていません。製造元の処方情報によれば、臨床医が基礎となる原因、心血管適応性、および現在の併用薬を評価した後にのみ治療を考慮すべきです。
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: 性的刺激中、陰茎海綿体で一酸化窒素が放出され、環状GMPを産生する酵素を活性化し、平滑筋を弛緩させて血流を増加させ勃起を支えます。バルデナフィルはPDE5を阻害し環状GMPの分解を防ぎ、その作用を延長します。作用発現は通常、服用後30~60分以内であり、臨床試験によれば効果は最大4時間持続し、シルデナフィルと類似しており、性的刺激は前提条件のままです。
Brand or generic — which to choose?
For most patients, authorised generics of Vardenafil are clinically equivalent substitutes for Levitra 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.
