Viagra is considered to be one of the most controversial and commonly disputed pharmaceutical drugs for over 30 years now. It is widely used all around the world to treat erectile dysfunctions, as well as pulmonary arterial hypertension. The word Viagra is just a brand name, and the chemical substance that is sold behind is called sildenafil citrate. It was invented by scientists in the United Kingdom and brought onto the market by an American pharmaceutical company named Pfizer Inc. Its main effect on the organism is relaxing the muscles in blood vessel walls in particular areas of the body.
It is not that hard to find affordable Viagra, so many British people who face erection problems use it willingly. In this way, they can enhance their sex life and become more confident by avoiding embarrassing situations in bed. However, as this drug is still controversial, it is common to buy Viagra online in the UK.
How does it work
In order for an erection to happen, a whole series of events must take place. The process starts with arousal signals received by the brain, and then everything depends on sufficient blood flow to the penis. This organ has two chambers, called the corpora cavernosa. During sexual stimulation, nitric oxide (NO) is produced in them, and it activates an enzyme named guanylate cyclase. As a result, the level of cyclic guanosine monophosphate (cGMP) is raised, making muscles relaxed. The already mentioned chambers have a rich network of blood vessels as well, so when they relax, blood can rush in. In this way, a certain pressure is obtained, and a person gets an erection. However, the impact of cGMP can be dampened by PDE5, and it is the Viagra’s task to inhibit PDE5.
This drug is absorbed into the bloodstream very quickly. Maximum concentrations can be obtained in an hour or even sooner.
Possible side effects and contraindications
The most commonly appearing side effect after taking Viagra is flushing or redness.
You should also be aware that this medication can be a reason for decreased blood pressure, especially one to two hours after using it. Therefore, people who already suffer from low blood pressure should consult the possible risks with their doctor.
In most cases, the sexual activity works positively on cardiovascular health. Nonetheless, if you have a disease associated with this system, you should ask a doctor if Viagra is safe for you. If you were already advised to avoid having sex, you should not take this drug for sure. Apart from that, people who have unstable angina or experienced a heart attack or a stroke ought to refrain from taking Viagra as well.
It should also be remembered that certain substances cannot be mixed. For this reason, do not use PDE5 inhibitors if you take long-term alpha-blockers or medications containing nitrates.
Reproductive system
Viagra can have excellent effects on your erection, but it does not affect your libido, so proper stimulation is still essential. Usually, the results can be kept for around 4 hours. However, there is a rare but severe side effect that can appear, called priapism. It is the condition when you get an erection lasting for too long and becoming painful. Keeping that in mind, if your erection does not weaken for over 4 hours, you should look for immediate medical help.
What is more, anatomical abnormalities of the penis can also be a serious contraindication to applying any PDE5 inhibitors. One of the most common ones is Peyronie’s disease.
Central nervous system
Viagra is very effective in improving your blood flow to the penis, but still, the brain is the essential organ when it comes to sex. Bearing that in mind, you need to know that this medication will not work if you are not in the right mood.
It happens that Viagra can cause headaches or a runny or blocked nose, or even a nosebleed. In some cases, men can also feel lightheaded or dizzy. Moreover, taking PDE5 inhibitors can also lead to muscle or back pain.
It is not common, but there have been cases of experiencing ringing in the ears or even hearing or vision loss.
Excretory and digestive system
Viagra is available in the form of film-coated pills. It is allowed to take this medication either with or without food, but it is the most advisable to swallow it about an hour before you have planned your sexual intercourse.
It is important not to overdose Viagra, so do not take more than one per day. Around 80 percent of Viagra is removed from the body in feces, and the rest is washed out with urine.
Take into consideration that sometimes using Viagra can upset your stomach, and you may experience indigestion. Apart from that, it has also been registered that PDE5 inhibitors may result in nausea or vomiting at times.
To sum up, it is known that Viagra can be useful in overcoming your erection problems, so it can help you to enjoy your sex life and satisfy your partner. However, it can have some side effects, so you should inform your doctor about all of your conditions that can be problematic. If there are no contraindications, you will get a prescription and will be able to order Viagra online in the UK or visit a traditional pharmacy to get it. In the US, you can look into companies like BlueChew to order Erectile Dysfunction medicine online.
