Levitra 60 mg is one variant of Levitra. It contains Vardenafil which relaxes the muscles of the blood vessel walls and increases the blood flow to the penis. A single pill is recommended to be taken in 24 hours. This pill can be taken with or without food. It is usually recommended to take this pill approximately 30 minutes to 1 hour before sexual intercourse. The effects of this medicine usually last for around 5 hours. Levitra 60 mg falls under the class of drugs known as PDE 5 inhibitors. It relaxes the smooth muscles present in the walls of the blood vessels and improves blood flow to certain areas of the body, including the penis. For an erection to occur, proper blood circulation is necessary. cGMP is a molecule that controls the contraction and dilation of blood vessels. cGMP is destroyed by an enzyme called PDE 5. Vardenafil in this medicine blocks the action of PDE 5 and allows cGMP to be produced properly. This allows more and more blood flow to the penis. As a result, pressure is created in the penis. Thus, an erection is achieved.
