ShareLikeLoading...I'm a 55-year-old male, no issues with age. My partner is very concerned because he is also taking nitrates for chest pain. Within a few hours he can achieve a hard erection (for a 4-hour time- frame). I’m reluctant to proceed further, but after a few weeks I can do it myself. I have been advised that nitrates can lower blood pressure, and nitrates can also lower blood pressure, so I’m taking the recommendation of a doctor and is considering a generic nitrates nitrates brand name. My ED is a result of my lungs (a narrowing of the blood vessels), and the chest pain is from nitrates. I’m worried about the nitrates, because in my opinion these are the most likely to cause the chest pain and that’s why I have taken the recommendation of a doctor and am considering a generic nitrates brand name.

Sildenafil belongs to a class of medications called phosphodiesterase type5 (PDE5) inhibitors. Viagra works by relaxing muscles found in the walls of blood vessels and increasing blood flow to the penis during sexual stimulation to get and keep an erection. Keep in mind that Viagra does not cure erectile dysfunction or increase sexual desire.
