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
비아그라 프로페셔널은 발기부전이 있는 성인 남성을 대상으로 합니다. 여성, 소아 환자 또는 임상적 진단이 없는 남성에는 적응증이 없습니다. 실데나필의 일반적인 처방 원칙에 따라 사용 전에 환자의 심혈관 건강 상태와 현재 복용 중인 약물 목록을 검토해야 합니다. 100mg 단일 제형은 내약성을 이유로 보통 더 낮은 시작 용량이 필요한 환자에게는 적합하지 않습니다.
Mechanisms compared
Because they share the same active ingredient, the mechanism is identical: 실데나필 시트르산염은 PDE5를 억제하여 성적 흥분 중 생성된 환형 GMP가 음경 조직에 축적되도록 하며, 이는 음경 동맥의 평활근을 이완시키고 혈류 유입을 증가시킵니다. 설하 경로는 분자를 구강 점막을 통해 전신 순환에 직접 전달하여 간의 초회 통과 대사를 부분적으로 회피합니다. 제품 문헌에 따르면 이는 일반 정제의 30~60분 대비 작용 발현을 15~30분으로 단축할 수 있습니다.
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.
