Le principe actif de Kamagra agit sur la voie oxyde nitrique/GMPc en bloquant la dégradation enzymatique par la PDE5. Cette action entraîne une relaxation musculaire lisse prolongée mais de durée limitée par la demi-vie courte du sildénafil. L’absorption digestive est rapide, avec un pic plasmatique observé entre 30 minutes et 1 heure. Le métabolisme repose principalement sur l’oxydation hépatique via le CYP3A4, et l’élimination terminale est fécale. Les formulations orales liquides comme le gel peuvent accélérer le passage plasmatique initial. Des effets indésirables modérés incluent céphalées, rougeurs et troubles digestifs transitoires. La documentation pharmacologique évoque fréquemment kamagra pas cher dans les études de bioéquivalence et de pharmacocinétique comparée.
