There are many drugs available to help combat erectile dysfunction (ED), and it may be difficult to see which is the best to take. The major choices come between Levitra, Cialis and Viagra. Of the three Viagra is most well-known, though this does not necessarily mean it is the best option.
All three drugs perform the same function in the way that they help relax hardened penile arteries which allows more blood flow into the penis, leading to erection. The drugs help to keep levels of cGMP high, which is a natural substance produced as a response to sexual stimulation. High levels of cGMP help the penile arteries to become relaxed and for a natural erection to occur. When men suffer from erectile dysfunction there is usually an enzyme that neutralizes the available cGMP, meaning that erections may not occur at all. Therefore, these drugs block that unwanted enzyme.
Dosage
Since all the drugs have the same effect of blocking the enzyme and helping keep cGMP levels high, it can be hard to know the differences between Viagra, Levitra and Cialis. Firstly, there are differences in the dosages needed for each product. For Viagra, patients usually begin on 50 milligram doses which can be changed based on the effectiveness of the drug. Viagra can be taken between 4 hours or 30 minutes before having sex.
In the case of Levitra, a 10 milligram dosage is the usual starting amount, and the drug is taken between 25 minutes to an hour before sexual activity. With Cialis, again a 10 milligram dose is normal, and the tablets are taken between 12 hours to 30 minutes prior to sex.
The drug right for you will depend on your circumstances, and whether you wish to take it as early as possible before sex, or at the last minute. It is useful to know these differences in reaction times, but it is also important to know how long the effects of the drug last.
How Long Do They Last?
Viagra will last around 4 hours, Levitra 5 hours and Cialis anywhere from 17 to 36 hours. Of course this may be an important factor in anyone’s decision.
Other Differences
The main reason that Viagra has become more well-known is that it was approved by the FDA in 1998, whereas the other drugs were approved in 2003. However, the cost of all three is roughly equal as are the side effects. All drugs will only work on roughly 70% of men, where the remaining 30% will require different treatment methods.
Side Effects
The side effects experienced by users of all drugs will range from headaches, to stomach aches or back pin. These side effects are extremely common with all of the drugs.
Conclusion
The most notable differences between the products are that Levitra will work the fastest, Viagra has a proven track record, and Cialis will last longer. Therefore, it is up to you to make a choice based on the factor that is the most important to you.
