What causes ED?

Depending on the cause, ED can be treated with the following medication groups Muscle Relaxants Phosphodiesterase inhibitors (PDE5) are a group of muscle relaxants which improve erection by increasing blood flow towards the penis on sexual stimulation. The most commonly prescribed PDE5 inhibitors in the US are sildenafil, vardenafil, tadalafil, and avanafil. All of these are taken orally, and the dosage depends on the level and severity of ED. Your doctor will recommend the right dose and frequency for you after a detailed evaluation of your ED. People with low blood pressure issues or those who are already taking medications for heart disease must be given PDE5 with great caution and only under the supervision of a health care professional. Apart from PDE5 inhibitors, Alprostadil is also used to treat ED. The drug is also a muscle relaxant which improves erection by facilitating blood flow into the penis. Your doctor may prescribe you Alprostadil as an intracavernosal injection or suppository. The injection is administered into the tip of the penis where the medication works locally to improve erection whereas the suppository is inserted into the penile urethra with a special applicator. Hormonal Therapy In some cases, ED is caused by low levels of the male sex hormone testosterone in the blood. Testosterone replacement therapy makes up for this deficiency by delivering adequate levels of testosterone through a transdermal application.
