Tadalafil is also known by the brand name Cialis. Cialis is used to treat impotency or to help maintain an erection. The drug is similar to Viagra and Levitra. Each of these drugs acts by blocking a chemical called phosphodiestrerase. However, Cialis is supposed to be more potent than Viagra.
The reason that Tadalafil blocks phosphodiestrerase is because this chemical is used by the body to stop an erection. You see, when a male is aroused a chemical is released to cause the blood vessels carrying blood into the penis to expand allowing more blood. At the same time this chemical constricts the blood vessels carrying blood out of the penis so that less blood can escape the penis.
Afterwards it is phosphodeistrerase’s job to restore the blood vessels to their normal size. By blocking this chemical, Tadalafil allows the blood vessels to remain expanded and contracted. This allows the blood to stay in the penis longer giving a longer life to the erection. The effects of this drug may last up to 36 hours after ingestion.
Side effects of Tadalafil may be mild and can include headaches, diarrhea, low blood pressure, upset stomach, blurred vision, or abnormal ejaculation. If you experience an erection for more than a few hours, you should consult your doctor.
Tadalafil should not be taken along with certain medications. Nitrates should not be taken at the same time as Tadalafil. You should wait at least 48 hours before taking Tadalafil if you have taken nitrates. Some medications slow down the body’s process of breaking down Tadalafil. As such these drugs can increase the level of Cialis in your blood. Telling your doctor about any medications you are using will let him know if he needs to reduce the amount of Tadalafil you are prescribed to prevent a build up of the drug.
