The Good: How Viagra Works for Your Body
The problem with erectile dysfunction is simple: there is not enough blood flow to the penis. We can counteract this effect by simply increasing the blood flow- usually with a muscle relaxer. But most common mu
scle relaxers will indeed relax the entire body- including the penis.
What is needed, specifically, is drugs that can relax the right muscles to stimulate blood flow to the penis- all while keep from relaxing the penis completely. Originally the cure came in the form of an injection- but today we have a pill form known as Viagra.
Getting to the Specifics: What Does Viagra Do?
To actually open up blood flow to the penis for an erection, Viagra decreases the levels of phosphodiesterase, or PDE. This enzyme decomposes a necessary chemical, cyclic guanosine monophosphate (cGMP). cGMP is necessary to obtain an erection, so therefore stopping the PDE from decomposing this chemical will result in a healthy erection.
Generally, the more cGMP that is built up means the greater the blood flow that is present. This will result in a much healthier erection, even when men suffer from conditions such as erectile dysfunction.
One interesting side effect (that is far from dangerous) is that Viagra will give some users a bluish-tinted perspective. This actually means that pilots are forbidden to take Viagra 12 hours before flying. Other than pilots, everyone else can sit back and enjoy the virtual blue sunglasses.
Viagra does have more serious side effects, however. Viagra is a prescription drug (as compared to over the counter) mainly because a doctor needs to check one's medical history before giving the green light to take the drug. Serious altercations such as heart attacks can result from taking Viagra, so a doctor visit is mandatory before taking Viagra.
Other more common side effects include headaches and related minor annoyances. Aside from these listed side effects, Viagra is actually a very safe drug to use- as compared to other alternatives.
Alternatives to Viagra: Improving on the Blueprint
Drugs such as Cialis work very similarly to Viagra. Whereas Viagra blocks one certain enzyme in the human body, drugs such as Cialis block another, and thus, different side effects result.
The main difference between Cialis-like drugs is that they won't cause color vision changes within users. Cialis users are also able to get an erection for around 18 hours in a day- from what Cialis claims. The only downfall to Cialis is that in 5% of men, muscle ache results from taking the drug.
Cialis is, likewise, generally preferred among pilots. It is also preferred when a male desires to obtain an erection at any point in the day- not just at specific times. However, both drugs have been long proven to give men their life back when concerning erectile dysfunction. Keep in mind that a doctor visit will be necessary to help rule out possible critical side effects.
Once the green light is given, the road to sexual satisfaction will once again be paved in gold.
