How do erectile dysfunction medications work?

A lot of people have heard about a blue tablet called Viagra. Sildenafil, which is the active ingredient was actually a component of a blood-pressure pill that was being tested way back, when and what was happening has an interesting side effect. It was helping a little bit with blood pressure but was actually helping much more with erections. So what happens is Viagra, Cialis, Levitra. All these medications are part of a class of medications called Pde5 inhibitors phosphodiesterase type 5 inhibitors. What it is doing it's it's blocking cyclic GMP and that's causing vasodilation. so blood vessels open up and when blood vessels open up, your blood pressure kind of goes down. that's the principle of some blood pressure medications. But what this particular medication does is that vaso dilates and a very interesting and specific area versus the rest of the body. What Viagra and these medications all require is the presence of functioning nerves, as well as functioning blood vessels.

What happens in terms of erectile dysfunction is testosterone Peaks. Erectile function Peaks you know when we're in our 20s, 30s, but then what happens is there's a progressive decline in testosterone. But there's also a progressive decline in erectile function at about age 40 to 50, 30 to 40 % of people may have some degree of erectile dysfunction, and it parallels the decade of age. So by the time you hit your 60s, 70s, 80s, 60 or 70 percent of people may actually have some degree of erectile dysfunction.

What happens with these medications is when you take them in the presence of functioning nerves and blood vessels, and well as appropriate stimulus? It actually causes an augmentation of the erection. However in some people, is you know, more moderate or severe erectile dysfunction, even viagra may not work, and that might require other medications or more significant help.


Vardenafil (Levitra, Staxyn)

Vardenafil sold under the brand names Levitra and Stachsen and is available as a tablet which brings us to how to use it just swallow the tablet with half a glass of water about half an hour to up to two hours before sexual intercourse. After taking it it will be effective for 4 to 5 hours. And for those of you that experience side effects like nausea and stomach compliance, you could also take it with some food as this lowers the stomach compliance.

Verdanaphil is part of a group of drugs called Pde5, thus cause an increased blood flow to the penis, leading to an erection. Therefore the benefit can be used to treat erectile dysfunction in adult males. However for it to work there needs to be sexual activity which brings us to the correct dosages to use. And here I want to mention that I can only provide you with some guidelines. Your specific diets will depend on your indication of use. The side effects you might experience and the severity of your symptoms therefore always use the precise amount and frequency your doctor prescribed you.

Uses and dose

Just as a guideline doctors often start with a dose of 10 milligrams about 30 minutes to 2 hours before sexual intercourse and for future use this dies can be adapted based on the effectivity of this dose and your tolerance for it. Your doctor might adjust it to a dose of 5 milligrams up to 20 milligrams if necessary.

Side effects

Vardenafil can be a very effective drug, but it also can have serious side effects. If you're looking for a complete list, check your leaflet, ask your doctor or your pharmacist now very commonly it might cause a headache. Commonly it can cause dizziness, blushing. nausea, dyspepsia and nasal congestion. Uncommonly it can cause a fast heart rate, palpitations, dizziness, stomach, pain, diarrhea, vomiting back pain and changes in your blood values. A rarely it can lead to changes in your blood pressure may cause pain of your chest, a heart attack, amnesia and a nosebleed which brings us to the safety of use. First of all Ferdinafil can cause several side effects like dizziness and blood vision. If you experience any of these, then please do not drive as this can be dangerous. Furthermore, when you combine Ferdinafil with alcohol, this can also increase the side effects. You might experience therefore be careful when combining boat and lastly for Vardenafil can have interactions with other drugs of taking. Therefore always discuss this with your doctor or your pharmacist.


Stendra or Avanafil

The drug is called Stendra or Avanafil, and it's similar to other drugs that we have on the market, namely Cialis, Levitra and Viagra. The studies that have been done show that this significantly improves erections.

There are side effects as there are with all of the drugs in this class, and patients should make sure they're aware of them before they start taking the drug. It's advised not to have it with alcohol or limit the alcohol intake, because it may increase the side effects. And also that men, who are taking drugs to help them urinate better, need to be cautious, because it may also increase the side effects.

You should take it within 15 to 30 minutes of planning to have sexual activity.

Viagra vs Cialis

Which is better Viagra or Cialis ?

These are popular pills that are taken to help blood flow and which we call vasodilation, which can help enhance erections for men who need help in that area. What is the difference between two pills Viagra is more intense, perhaps a Little Bit Stronger if you will than Cialis, but can cause more side effects:

  • Facial flushing
  • Headaches
  • Stuffy nose

Cialis not as much, though it can cause some muscle aches. The biggest difference between the two is the duration of action. Viagra has a shorter duration of action, Cialis has a longer duration of action. Meaning, if you take a Viagra, it'll stay in your system for approximately 6 hours, Cialis - 36 hours.

I tell patients: if they take a Viagra on a Friday afternoon, they'll likely be optimized for Friday evening. They take a Cialis on a Friday afternoon. They'll be optimized both Friday night and Saturday night.

Both pills have a maximum dose and a lower dose Viagra's maximum dose is 100 milligrams and a partial dose is 50 milligrams. Cialis's maximum dose is 20 milligrams and a lower dose is 10 milligrams. Both of these pills should be taken two hours prior to the desired effect. If you do have a heart condition, please consult your cardiologist before taking these pills.
