Extra Super Avana has a quicker onset of action, and starts acting within 15 minutes of uptake. Avanafil acts by inhibiting a specific phosphodiester ase type 5 of an enzyme which is found in various body tissues, but mainly in the corpus cavernosum of penis. The enzymatic inhibition by Super Avana leads to prolonged and sustained penile erection. Dapoxetine acts by inhibiting the serotonin transporter, leading to increased serotonin's action at pre, and postsynaptic receptors
