Suffering from erectile dysfunction can have far-reaching effects on quality of life. In addition to affecting the ability to enjoy a healthy sex life, it also impacts on feelings of self-confidence and self-worth.
For this reason, treating erectile dysfunction is important, and Levitra is an effective medication that you can use. A substance called cGMP is responsible for relaxing smooth muscle tissues. It affects the walls of blood vessels throughout the body, including the penis. When these blood vessels dilate, they carry more blood to the penis and help men achieve a stronger erection.
Sometimes, the body also produces an enzyme called phosphodiesterase type 5 PDE5. When cGMP combines with PDE5, it can seriously reduce blood flow and is a common cause of erectile dysfunction problems. Levitra is an erectile dysfunction treatment that is classed as a PDE5 inhibitor. By doing so, the drug encourages the muscles in the penis to relax, increasing blood flow, and helping men to achieve an erection when aroused.
Levitra tablets come in film-coated tablets. The medication should be taken 30 minutes to one hour before you want to have sex. The effects usually last up to five hours. For the best results, you will need to be sexually stimulated when taking Levitra. Swallowing the tablet alone will not give you an instant erection.
