When do men stop having erections?

Fildena 100 is a PDE-5 inhibitor which is used for treating the condition called erectile dysfunction (ED). It is used to improve sexual performance and keep an erection. It works by relaxing the penile smooth muscle and increasing blood flow to the penis.

The drug also increases the level of cGMP in the body. cGMP is an enzyme that is responsible for handling the stimulation of smooth muscle cells in the vessels. When there is enough blood flow to the penis, a man gets an erection that lasts longer.

Sildenafil citrate is the main ingredient in Fildena 100. It is a selective inhibitor of phosphodiesterase 5 and increases the level of cyclic guanosine monophosphate. This is the most important metabolite of sildenafil. It stimulates the synthesis of nitric oxide in the body. Nitric oxide helps in the vasodilation of blood vessels. This in turn makes it easier for nitric oxide to circulate through the veins.

This mechanism of action is very useful in the treatment of erectile dysfunction. It also improves the flow of blood to the lungs in patients with pulmonary arterial hypertension (PAH).

It is very safe to use when taken according to the doctor’s instructions. Nevertheless, some side effects can occur. These include headache, diarrhea, and flushing (sense of warmth in the face, ears, neck, and trunk).

If you are using other medications for your health, check with your doctor before taking Fildena 200. These drugs can interact with Sildenafil and reduce its effectiveness.
