Sildenafil doesn’t cure ED. It is used to treat ED symptoms. Likewise, Sildenafil doesn’t fix PH. It only helps to control blood pressure in the arteries of the lungs.
Sildenafil belongs to a group of medications called PDE5 inhibits. These drugs inhibit the activity of phosphodiesterase enzymes that break down cyclic Guanosine monophosphate. This type of molecule relaxes smooth muscles in the body, such as blood vessels that allow the penis to become erect. Sildenafil increases blood flow by allowing the arteries to relax enough to allow more blood to pass through them.
Sildenafil is rapidly absorbed into the bloodstream and reaches its maximum concentration in approximately 1 hour for most users. Generic Viagra can cause blood pressure drops, just like other PDE5 inhibitors. Ask your doctor if Sildenafil is safe for you if you take blood pressure medications or have low blood pressure.
Sildenafil does not cause an erection by itself and doesn’t increase sexual desire. Still, sexual stimulation is required. Sildenafil, however, can help with erections for most people.
In 2007, a 4-year study concluded that Sildenafil could be safely used over the long term. Another 2016 study based on clinical trials found that Sildenafil was effective regardless of age.
