Levitra is a treatment for erectile dysfunction, they come in tablet form or orodispersible and they contain the active ingredient Vardenafil. Vardenafil is a phosphodiesterase type 5 inhibitor and it prevents the action of a chemical in the body called phosphodiesterase type 5. Levitra like other medicines can be sought from your GP however you can buy Levitra online from a reputable seller.
Erections are gained when signals from the nervous system and chemical messengers are released within the tissues of the penis; one of the chemical messengers is called cyclic GMP. Cyclic GMP is what causes the blood vessels in the penis to widen and allow more blood to enter the penis, making it hard and erect.
However Cyclic GMP is normally broken down by another chemical in the body called phosphodiesterase type 5. Which as previously mention what Vardenafil prevents so Cyclic GMP is not broken down which results in the blood vessels are kept dilated for longer, improving blood flow to the penis and maintaining an erection.
You can Levitra with our without food, however it’s not recommended that you take it with a meal which is high in fat because this could delay the onset, all tablets should also be swallowed whole. You should take the tablets 25 to 60 minutes before sexual activity. The orodispersible tablet which melts on the tongue should be taken approximately 60 minutes before sexual activity because they can take longer to work.
There are some things you need to be aware of before taking the tablets and some side effects can be caused: You shouldn’t take Levitra and drink grapefruit juice because it may increase the level of this medicine in your blood and increase the risk of side effects. Also if your erection lasts longer than four hours (priapism), consult a doctor immediately, treatment should not be delayed as it could cause damage to erectile tissue in the penis.
