Erectile dysfunction, also known as ED, is a condition present in one way or another in millions of males in the word, some of them quite young and with no obvious health problems. ED can affect patients of any age, social status and health condition, but it may be caused or contributed to by a number of factors, such as age, health, presence of stress and other aspects of physical, psychological or mixed origin. Erectile dysfunction usually renders the patient unable to attain an erection that would be hard enough to have sex or the erection achieved is lost before the patient has a chance to complete sexual intercourse. There are ways to treat erectile dysfunction, but taking special medications that work on a physical level and make sure the patient can achieve harder and durable erections is probably the most common solution.
When it comes to generic ED pills available online, there are three active ingredients you will be choosing between. Sildenafil citrate is probably the most commonly ordered one, followed by tadalafil and vardenafil. These active ingredients are found in three brand name drugs almost everyone heard about - Viagra, Cialis and Levitra, but when you buy ED pills online, you will find them under different brand names. However, since those cheap ED pills contain the same amounts of the same active ingredient, they will work for you in the exact same way. Which of the three to choose is the most important question though, because every patient with erectile dysfunction wants to put an end to the annoying and rather embarrassing symptoms without having to go through the whole trial and error routine.
What makes those three kinds of pills for ED similar is the way they work. Once in your body, sildenafil, tadalafil or vardenafil will block a specific enzyme in the body known as phosphodiesterase type 5 (which is why they are classified as PDE5 inhibitors). That way, they make it possible for the penile tissues to fill with blood keeping that blood from escaping back into the body. That way, an erection can be achieved and kept for longer than usual. However, that mechanism of action also means the effects of those meds are temporary and a pill needs to be taken every time prior to sexual intercourse.
When you buy ED pills online, you should be aware of the difference between them. For instance, if you buy ED pills containing tadalafil, you can count on up to 36 hours of efficiency with the pill starting to work after 30-60 minutes. The efficiency of drugs containing sildenafil can be affected by alcohol consumption and meals that contain a lot of fat; the efficiency period for those is up to 4 hours. When buying vardenafil-containing ED pills online, you can count on up to 5 hours of efficiency and fewer potential side effects.
