Viagra is one of the world’s most popular erectile dysfunction drugs. Its fame was truly global when it achieved FDA approval in 1998 and was subsequently sold in over 100 countries. The original form of the drug was a blue pill that was subsequently changed to a red version. In many nations, including the US, Canada and Australia, Viagra is available as a generic alternative to branded drug products like Cialis and Levitra. However, in some places like Japan, it is still considered a prescription drug and is not available over the counter.
Key Facts About Viagra
Viagra is a phosphodiesterase type 5 (PDE5) inhibitor, which is an enzyme that breaks down cGMP (cyclic guanosine monophosphate). Inhibition of this enzyme results in increased levels of the second messenger cGMP in the body, which is responsible for relaxation of smooth muscle cells in the arteries. As a result, blood flow is increased to the penis and results in an erection. The elevated levels of cGMP also inhibit the release of nitric oxide, which prevents further relaxation of muscles in the penis and results in an inability to achieve an erection.
Because of its unique mechanism of action, Viagra is often mistakenly thought to be a form of morphine or other opiates. However, this is not the case and it is certainly not illegal to possess or purchase Viagra. The drug is also not associated with any serious side effects other than those typically associated with any pharmaceutical product, which includes headaches, upset stomach, heart failure, and low blood pressure. Although it is a very common misconception, some older people with dementia or Alzheimer’s have experienced psychosis as a result of taking Viagra. However, this risk is very small and occurs only in exceptional cases. Nonetheless, it is still considered a minor side effect of the drug.
How Does It Work?
In general, Viagra works by increasing blood flow to the penis and thus resulting in an erection. However, it does this in a very specific way that is somewhat different from other ED drugs. First, the firm muscles in the penis begin to relax and expand, which allows more blood into the organ and results in an erection. Second, the increased blood flow results in heightened sensitivity to sexual stimulation, which allows for better arousal and greater satisfaction during sex play. Finally, because there is more blood flow to the penis, there is also more oxygen and nutrients, which results in thicker and more robust erections. These benefits make Viagra an ideal choice for men with ED, particularly those who experience erectile dysfunction after age 50.
Other PDE5 inhibitors, such as Cialis, have also been shown to increase penile blood flow and result in an erection. However, these drugs also work by inhibiting the breakdown of cGMP, which is why they are also referred to as cGMP inhibitors. Cialis is approved for use in the United States and other countries and is available as a generic alternative to branded drug products like Viagra and Levitra. It is also commonly used as a pre-workout supplement to enhance athletic performance. Like Viagra, Cialis is also effective in treating ED and has been shown in clinical trials to be highly effective in enhancing sexual function in men with diabetes.
Levitra (levoran) is another common PDE5 inhibitor used to treat ED and is available in a variety of countries across the globe. It is also approved for use in the United States as a treatment for ED and has been shown to be more effective than Viagra in treating the condition. Like Cialis, Levitra is also commonly used as a pre-workout supplement in athletic settings and has been shown to increase the amount of time a person can stay erect and maintain sexual stimulation, which may also enhance athletic performance.
What Are The Main Differences Between Viagra And Other PDE5 Inhibitors?
There are a few important differences between Viagra and other PDE5 inhibitors. First, Viagra is not approved for use in children and it is certainly not recommended for use in women. Second, due to its vasodilating effects, Viagra can cause headache, upset stomach and low blood pressure in some people. Third, while most other PDE5 inhibitors work in a similar manner to Viagra, they are less effective at increasing blood flow to the penis. Finally, the symptoms of overdosing on Viagra are generally different from those of other PDE5 inhibitors. For instance, some overdose victims report experiencing nausea, vomiting and diarrhea along with very high blood pressure, which may lead to heart attack or stroke. This is why it is generally considered a dangerous drug and people who use it regularly should be careful not to exceed the recommended dose or take it at all if they are already feeling unwell. Moreover, taking high doses may even cause erections that last for an hour or more, which is commonly referred to as an orgy episode and may be a sign of addiction. This is why it is not recommended for use in people with dementia or Alzheimer’s disease. Lastly, the half life of Viagra is very short, which makes it a very temporary solution for ED. As a result, it is generally recommended as a short-term medication or for people with acute ED issues. Longer-term therapy is not recommended due to the potential for adverse side effects and addiction. Similarly, while acute overdosing on Viagra is very rare, it is still a potential risk and it is something that users should be careful about, as there is no evidence that it is safe for people to take in large doses over a long period of time.
Viagra is a great option for people with ED, particularly those who experience the problem at some point in their life. In particular, it is very effective in treating both the physical and psychological aspects of the condition and it has been proven in numerous clinical trials to be safe and highly effective. This makes it a favorite among doctors and patients who need help treating erectile dysfunction and enhancing their overall sexual experience.
