Le sildénafil présent dans Kamagra exerce une inhibition réversible de la PDE5, modulant la cascade GMPc et favorisant une vasodilatation localisée. L’absorption digestive varie selon la forme utilisée, comprimés classiques ou gels oraux. La distribution tissulaire est large et la liaison protéique élevée, avoisinant 96 %. La métabolisation hépatique génère un métabolite actif contribuant à l’effet pharmacologique global. La demi-vie reste courte, avec disparition plasmatique en quelques heures. Les interactions significatives concernent surtout les nitrés organiques et inhibiteurs puissants du CYP3A4. Dans les publications techniques, kamagra en ligne est souvent cité dans le cadre d’analyses comparatives portant sur les différences de formulations et de cinétique d’absorption.
