Male impotence was once an embarrassing subject, with many males reluctant to discuss their erectile problems for fear of ridicule or admonishment, either by peers or health professionals. The issue was further complicated by the fact that until the late 90’s, there was no simple solution available – but that has all changed.

Right now there are a large number of different medications which can be easily purchased online in order to address a man’s inability to get and maintain an erection. You may be thinking “How does it work?” – the answer is quite simple and might surprise you. In terms of where to buy these medications, there is no more reliable a vendor than sildenafilviagra.com. However, it’s advisable to understand how Sildenafil works before making a purchase, in order to be completely informed of how ED medication can best work to improve your sex life.

What Is Sildenafil?

Sildenafil is the generic trade name for a drug most commonly referred to as Viagra. It belongs to a group of medications called phosphodiesterase type-5 inhibitors (often abbreviated to PDE-5 inhibitors). There are a number of similar PDE-5 inhibitors, although Sildenafil is arguably the most popular across the world.

Sildenafil citrate was initially discovered by medical researchers who were seeking to develop a medication to treat angina. However, during trials, one of the noted Sildenafil side effects male patients reported was an added ability to maintain an erection. Ever since this discovery, the medication has been used for anti-ED purposes to fight impotence.

The drug generally has a shelf life of approximately two years, which means it can be stored for use as and when it is required – allowing you to simply place an order and keep your tablets in a safe place until you need it.

If you find yourself struggling with erectile problems, it’s easy to feel bad and consider that it isn’t a simple health issue which can be rectified – you may even be thinking “What is the use in taking tablets?”

The good news is that affordable Indian Sildenafil products are readily available online – however, it is strongly recommended that advice from a qualified doctor is sought before taking a tablet. A physician will be able to define the correct dosage and provide you with important information, even if you intend on purchasing your treatment online as opposed to over the counter.

How Does Sildenafil Work?

When it comes to PDE-5 inhibitors, some of the most commonly asked questions include how to take and how to use Sildenafil correctly. When asked “What does it do?”, many people are under the impression that the drug instantly causes an erection. Contrary to this belief, Sildenafil does not immediately cause the penis to become erect. In order to understand exactly how Sildenafil works for men, you first need to have an understanding of what happens when a man gets an erection.

When a man becomes sexually stimulated, it causes the body to release a compound called nitric oxide; an enzyme which then produces a chemical called cyclic guanosine monophosphate (often referred to as simply cGMP). cGMP functions to help relax the penis’ muscle cells.

The results in the arteries within the penis dilating, allowing blood to flow much more easily into the organ. Once the erectile tissue has sufficiently filled with blood, an erection is achieved. Of course, this means that you must be mentally aroused before the body facilitates the release of nitric oxide, meaning Sildenafil alone will not simply cause an erection. Instead, Sildenafil acts on the physical symptoms of erectile dysfunction. If you are wondering how long does it take to work, the answer can vary dependent on diet and physiology, although it generally begins to act fast after consumption.

Uses of Sildenafil

Although it is primarily used to treat men who have problems getting and maintaining erections, Sildenafil can also be used in order to treat high blood pressure within the lungs (known as pulmonary hypertension).

Although the most obvious benefit is an increased sexual performance, the blood vessel widening properties in the lungs help to increase the level of exercise capacity, leading to increased overall health and well-being in both men and women.

How Long Does It Take to Work?

Before an online or OTC purchase, most men want to find out the basics of how soon Sildenafil kicks in and how long it lasts for. Of course, there’s no exact science to predict precisely how long it will last, as physiological factors (height, weight age and so on) combined with circumstantial factors (like how much food a person has had to eat during the course of the day) will play a part to define how long the drug will last for. The majority of men report that Sildenafil works within one hour, and lasts for anything up to four.

Of course, this doesn’t mean you’ll have a constant erection for four hours! It merely means that you will have the ability to maintain an erection during this four-hour period. It is worth noting that Sildenafil works best when taken on an empty stomach, approximately 30 minutes before engaging in sexual activity.

For men in younger age brackets, low doses work well – although the mechanism of action for older males can differ to the point where higher Sildenafil doses are required. As a general starting point, Viagra 50mg is the most common starter dose on prescription, and if it is not working the dosage can be upped until Viagra 200mg or the correct action is achieved. A qualified medical professional or doctor should be able to talk you through the best Sildenafil options, and what works best for you – including any indications as to why you may need to avoid taking Sildenafil (for example, if you are currently taking medication which might negatively interact with PDE-5 inhibitors, such as nitrites). Certain antibiotics and other medication should not be taken with Sildenafil:

Medication	Reaction
Amyl Nitrite	Causes blood pressure to fall
Amoxycillin	Causes increased effects of Sildenafil
Clarithromycin	May cause priapism
Erythromycin	Causes increased effects of Sildenafil
Isosorbide	Causes blood pressure to fall

How Long Does Sildenafil Last in Your Body?

Sildenafil has a relatively short half-life, and the fact that the effects wear off relatively quickly makes it popular in comparison to other PDE-5 inhibitors where side-effects can be felt for upwards of 36 hours. If the effects of Sildenafil wear off quicker than anticipated, another dose can simply be taken directly after, on an ad-hoc basis – provided it is taken at the right dosage. How long it lasts in the body will again vary on physiology, but in comparison to drugs like Cialis, it lasts in your system for a much shorter period of time.

Is It Legal to Buy Sildenafil Without Prescription?

Although OTC Sildenafil without a prescription is not currently legal in many countries, it is possible to purchase medication online at a fraction of the cost of brick and mortar drug stores. In actual fact, many of these medications from India are manufactured for use in the United States and purchasing online is just a means of bypassing the middleman. Sildenafil purchased from a reputable online vendor is completely safe – providing you know where to buy, as there are a number of unscrupulous sellers offering sub-standard quality PDE-5 inhibitors. In order to ensure that you receive genuine Sildenafil, always choose a quality dealer like our Sildenafil Viagra online pharmacy.
