People suffering from the problem of erectile dysfunction need a medication that not only provides them strong and stable erections, but also a good bout of vigor and vitality to go with. While people can take multiple drugs to derive such qualities from them, using a single pill containing sildenafil citrate can more than do the trick. Right since its inception, sildenafil citrate has featured as the main and active ingredient in the most number of leading anti-impotence medicines of the world, for instance Viagra. Sildenafil citrate is essentially a PDE-5 blocker, which is what makes it so potent against ED.

Erectile dysfunction
Erectile dysfunction can be simply defined as a condition of the male reproductive organ where it becomes unable to achieve or sustain the states of hardness and erection. The reason for this to happen is understood as the deficient flow of blood to the male organ, which requires its erectile tissues to be completely filled up by blood so that it can attain proper erection. However, as not enough blood becomes available to the organ, it undergoes the problem of erectile dysfunction.

Causes of ED
The condition of erectile dysfunction is mainly caused due to a condition of the blood vessels known as atherosclerosis, which may be caused directly, or by way of some serious medical conditions such as diabetes, heart attack, etc. Nevertheless, atherosclerosis is claimed to be the prime cause behind ED because this condition causes blood supply to the male organ to be cut off. What essentially happens during atherosclerosis is that the blood vessels undergo deposition of fats, cholesterol, and other waste substances on their interior sides. This causes a hindrance in the flow of blood because the gap in between two sides of the blood vessels becomes severely constricted.

In case of ED, the blood vessels responsible for carrying blood into the male organ are affected by atherosclerosis, which is what cuts off the blood supply to the organ. Additionally, ED can also be caused due to a person’s poor lifestyle habits such as excessive smoking and drinking, improper and irregular diet, taking inadequate rest, physical inactivity, lack of personal hygiene, etc.

How does sildenafil treat ED?
Sildenafil citrate basically belongs to the PDE-5 class of drugs, which means the anti-impotence medicines containing this drug have their main purpose as the elimination of PDE-5 enzymes. Simultaneously, sildenafil drugs also perform the function of facilitating the release of nitric oxide and cGMP enzymes in the body. Elimination of PDE-5 enzymes becomes necessary because these tend to hamper the proper flow of blood to the male organ. After all these processes are ensured in the body, the rate of blood circulation is improved in the body and as a result, greater amount of blood is able to reach all organs of the body, including the male organ. Using the enhanced flow of blood available to it, the male organ is eventually able to achieve stiffness and proper erection.

Dosage
Medicines containing sildenafil citrate may be present in a variety of forms such as tablets, chewable tablets, dissolvable tablets, melting tablets, oral jelly, etc. Whichever form of medicine you’re taking, make sure that you thoroughly go through the instruction panel provided with the pack. Also, it is most advisable to take sildenafil medicines only in the amount prescribed by your doctor, as self medication or overdosing can lead to some fatal side effects, and even death. Please ensure that you take this drug at least an hour before commencing an intimate session. For best results, take this drug on an empty stomach, or after a low fat meal.
