Different views on Sildenafil
Since Sildenafil was invented it caused much controversy and dispute with or without reason. Critical perception of negative features was widely spread in mass media. Alongside with it, many advantages of Sildenafil were discovered. From time to time we read about the positive influence of this substance: the performance and endurance of high-altitude athletes can improve with it, it helps women curb menstrual cramping, improves heart function in kids and so on. But what is more important, it helps to return male potency acting through its ability to inhibit degradation of cGMP that is responsible for blood flow in the penile area.
Efficacy of Sildenafil: is it helpful for all?
Many happy men were able to save their relationship with help of this medicine. Nevertheless, it can't help absolutely all. The medication is not effective for some people and even can be harmful for men who had heart attack and take alpha blockers. The risk group includes patients who suffer from high cholesterol, diabetes, have kidney problems and other conditions. Such people develop side effects more often than others. The doctor should determine if it is so important to take Sildenafil for them. In case, the risk is big, the alternative treatment should be found.
Side effects of Sildenafil
It can bring to the negative effects such as headache, poor vision, priapism, sickness and many others. The person needs to be stimulated if he wants to achieve the erection. Many men wait for the reaction but it will not follow until the patient gets stimulation.
How Sildenafil works
When penis is not erect, the arteries are constricted. The blood does not flow and pressure is not formed in the penis. Without blood pressure the erection does not occur and penis is limp. Thanks to it the arousal opens veins, which let the pressurized blood in. As a result, erection occurs.
Invention of Sildenafil
Every person can buy Sildenafil citrate online but there was time when this popular ED remedy was tested to become a medication to treat pulmonary arterial hypertension and angina pectoris. During the testing period interesting side effect was discovered. The participants asserted that this medication induced erection. This is how Viagra appeared. Viagra, Revatio are the trade names of Sildenafil citrate but there are many more brands that use this component to manufacture generic Viagra. It has also become a trade name already that is manufactured by pharmaceutical companies in India.
Why buy generic Sildenafil
When patients buy Indian Sildenafil, no prescription is asked, so they prefer simpler way to get the remedy instead of visiting the doctor to ask for prescription. Taking into account that generic Sildenafil is not worse than branded Viagra it makes sense but what if the drug is not suitable for patient? It is hard to predict all negative consequences in this case. The patient should make a decision with all awareness to determine if it is worth to buy Sildenafil without prescription.
