Kamagra 100 usa tablets are used to treat erectile dysfunction (also called impotence) in men. This is when a man can't get or keep a hard, erect penis that is good for sexual activity. This happens when there isn't enough blood flow to the penis. Kamagra 100mg tablets relax the blood vessels in the penis, which increases blood flow and causes an erection, which is the normal response to sexual stimulation. Kamagra 100mg tablets, on the other hand, only work if you are sexually aroused.
How does Kamagra work?
The sildenafil in Kamagra 100mg tablets works on the tissue in the penis that controls erections to increase blood flow, which causes an erection. When the erectile tissue of the penis is stimulated sexually, nitric oxide is released. This turns on an enzyme called guanylate cyclase. This enzyme makes more of a chemical called cyclic guanosine monophosphate (cGMP), which relaxes the blood vessels in the penis and lets blood flow into the soft erectile tissues to cause an erection. Another enzyme called phosphodiesterase type 5 (PDE5) breaks down cGMP. This stops blood from flowing into the penis, which causes an erection to stop. Kamagra 100mg tablets stop PDE5 from working, which fixes erectile dysfunction by letting the natural process of sexual stimulation turn on the cGMP mechanism that gets and keeps an erection.
How long does Kamagra last?
Kamagra 100mg tablets should be taken about an hour before you plan to have sex. If you are sexually excited, it usually helps you get an erection in about 30 minutes that lasts about 4 hours. If you are not sexually aroused, Kamagra 100mg tablets won't work.
