Impotence in men with erectile dysfunction is treated with a prescription drug called Kamagra Tablets, 100mg. Its outcome is that more blood is drawn to the penis. This helps to initiate or sustain male erections. Depending on the person, work may take a varying amount of time, but it often lasts between 30 and an hour. It is possible to take a Kamagra 100mg pill with food or without food.
