Erectile Dysfunction At A Glance: Treatments include psychotherapy, adopting a healthy lifestyle, oral PDE5 inhibitors (Viagra, Levitra, and Cialis), intraurethral medications, intracavernosal injections, vacuum devices, surgery, and working with doctors to avoid medications that can impair erectile function. viagra cialis levitra online buy viagra The common PDE5 drugs approved in the United States are sildenafil (Viagra), vardenafil (Levitra), or tadalafil (Cialis). Actual head-to-head trials between these drugs have not been done to date to see which is the superior drug. Details on each of these medications for erectile dysfunction are outlined below. Penile erection is managed by two mechanisms: the reflex erection, which is achieved by directly touching the penile shaft, and the psychogenic erection, which is achieved by erotic or emotional stimuli. The former uses the peripheral nerves and the lower parts of the spinal cord, whereas the latter uses the limbic system of the brain. In both conditions, an intact neural system is required for a successful and complete erection. Stimulation of the penile shaft by the nervous system leads to the secretion of nitric oxide (NO), which causes the relaxation of smooth muscles of corpora cavernosa (the main erectile tissue of penis), and subsequently penile erection. Additionally, adequate levels of testosterone (produced by the testes) and an intact pituitary gland are required for the development of a healthy erectile system. As can be understood from the mechanisms of a normal erection, impotence may develop due to hormonal deficiency, disorders of the neural system, lack of adequate penile blood supply or psychological problems. Restriction of blood flow can arise from impaired endothelial function due to the usual causes associated with coronary artery disease, but can also be caused by prolonged exposure to bright light. vipps viagra no prescription online india buy viagra buy cialis generic online buy cialis generic online Vardenafil (Levitra) was the second oral medicine approved by the U.S. FDA for the treatment of erectile dysfunction.
