Erectile Dysfunction Drugs – Tadalafil

Erectile Dysfunction is a medical term for a situation whereby a patient experiences difficulties in obtaining and maintaining an erection, due to either physiological or psychological problems. These symptoms range from the penis not being stiff enough to perform full sexual intercourse, to erections that cannot be maintained for a sufficient period of time, to the point of having no erection at all. While this problem may occur occasionally, erectile dysfunction could turn into a regular event if not treated immediately. The search for a cure led to the creation of the drug Tadalafil, developed by GlaxoSmithKline in partnership with Lilly ICOS, LLC, in a project that started in August 1991.

Marketed under its commercial name, Cialis, Tadalafil is a drug used to prevent erectile dysfunction. Similar to its rival, Viagra, Tadalafil suppresses the enzyme that regulates blood pumping into the penis, causing an erection and inhibiting erectile dysfunction. What makes Tadalafil different from the rival pill is the longer period of time the drug affects the body. Viagra remains active for 4-5hours while Cialis can last for up to 17.5hours. As a result of the length of time it remains in the bloodstream, Cialis is now being studied as a daily remedy for pulmonary arterial hypertension.

Common side effects associated with this erectile dysfunction drug are back and muscle pains, headache, runny or stuffy nose and indigestion, but these symptoms normally dissipate within a few hours. The back pains and aching muscles usually occur around 12-24 hours after taking the drug, but disappear after two days. Following post market reports, the US Food and Drug Administration have recently discovered that Tadalafil can cause vision impairment or a possible loss in hearing.
