Tadalafil appartiene alla classe degli inibitori selettivi della fosfodiesterasi di tipo 5, con un profilo farmacocinetico caratterizzato da un’emivita terminale di circa diciotto ore. Dopo somministrazione orale viene assorbito rapidamente e raggiunge concentrazioni plasmatiche massime in due ore. La biotrasformazione avviene principalmente tramite CYP3A4 con formazione di metaboliti inattivi, escreti in prevalenza con le feci. L’elevato legame alle proteine plasmatiche (>90%) assicura una distribuzione stabile. Nei confronti delle altre molecole della stessa classe, cialis compresse italia è noto per la durata prolungata dell’attività farmacologica.
