Men with erectile dysfunction are treated with the oral medication Fildena Australia, also referred to as the purple pill. It enhances blood circulation throughout the body, especially to the penis, by relaxing the smooth muscles found in blood vessel walls. It includes Sildenafil Citrate, which helps men get or maintain an erection strong enough for sex. The group of medications known as PDE 5 inhibitors includes Fildena. It enhances blood circulation by preventing the activity of the PDE-5 enzyme, which inhibits blood flow. Nitric oxide (NO), which is produced when a person is sexually excited, is released into the penis.
