Sildenafil also known as Viagra, is used to treat male sexual function problems (impotence or erectile dysfunction-ED). In combination with sexual stimulation, sildenafil works by increasing blood flow to the penis to help a man get and keep an erection.

The troche form results in faster absorption into the blood stream, which in turn can help with performance anxiety.

Remains active for four to six hours with onset often under 30 mins.
