How Levitra works in treating impotence
Levitra is a drug that falls in a group of drugs known as PDE5 inhibitors, PDE5 standing for phosphodiesterase type 5. In order to explain how the drug works, we are going to look at the sequence of events that take place during an erection.
When the body is sexually stimulated, it starts to release nitric oxide (NO) in the vascular organs of the corpus cavernosum. The corpus cavernosum is one of two spongy tissues located in the penis, which fills up with blood during an erection. When the secreted NO reaches the corpus cavernosum, it activates guanylate cyclise – an enzyme that catalyzes the increase of cyclic guanosine monophosphate. Cyclic guanosine monophosphate is the substance that causes the smooth muscles in the spongy region of the penis to relax. The relaxation of the spongy tissue precedes an increase in blood flow, which then effects an erection. The role of the drug is to slow the breakdown of cyclic guanosine monophosphate by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which then helps maintain an erection during sexual intercourse.
Levitra is a prescription drugs and comes in doses ranging from 2.5mg – 20mg. The recommended dose is 10mg. The drug can be taken a couple of hours before indulging in sexual activity. The medical specialists recommend that the drug be taken once a day, in order to avoid other possible side effects that can further increase impotence. It is important to note that this drug is no wonder drug; it does not guarantee an erection. There is still a need of sexual stimuli even after taking the drug.
Just like any other drugs, Levitra can have side effects. Known side effects include nausea, drowsiness, skin rashes, reduced appetite and headaches. There are also severe cases though rare, in which the drug can cause heart related diseases. It is also worthwhile to know that persons that have conditions that are dangerous such as hypertension and other diseases that are associated with the cardiovascular system must not administer the drug.
It is therefore a good recommendation to you visit your doctor, they carry out all the necessary tests and determine the cause of your erectile dysfunction. Your doctor will be able to determine accurately whether it would be suitable to let you take the drug as well as determining the dosage level, which would be ideal for your condition.
