Experts researching the use of Viagra have discovered that the original blue pill is no longer just an impotence treatment. Apart from being known as an effective erectile dysfunction treatment, this impotence pill can also help treat some other health conditions. A study shows that generic cialis can be used to treat a condition known as Raynaud’s phenomenon or Raynaud’s.
What is Raynaud’s phenomenon?
Raynaud’s phenomenon is characterized by spasms of the blood vessels in the hands and the feet caused in response to stress or exposure to cold. It affects about 3-20% of the total adult population worldwide. Raynaud’s is most commonly found in women. It involves an interruption of blood supply to the extremities (sometimes to ears and nose also). Arteries supplying blood contract due to spasms and cause pain, numbness, or tingling in extremities due to an intermittent lack of blood supply. In extreme cases, Raynaud’s can lead to ulceration or tissue death in the extremities and in other parts that are affected by it.
How can Viagra help treat Raynaud’s phenomenon?
In a study carried out by scientists in Germany, 18 patients with severe Raynaud’s phenomenon were monitored. These patients had failed to respond to at least two other drugs used to treat this condition. Scientists randomly gave 50 mg of Viagra twice daily to these patients for four weeks. They were then put on one week of “pill-free” period with no treatment. The study reported that blue pills significantly reduce the frequency of Raynaud’s attacks and its duration. A substantial healing of sores caused by ulceration was seen in six patients, with complete disappearance in two patients.
Sildenafil, a phosphodiesterase type 5 inhibitor, is the active ingredient in Viagra. It aids the relaxation of the smooth muscles around the penis, so as to increase blood flow. This drug basically acts as a vasodilator. Results obtained from the trial demonstrated that capillary blood flow increased and the mean capillary blood flow velocity almost quadrupled in patients after treatment with this impotence pill. Viagra for Raynaud’s is at its initial phase, so you should first consult a doctor before considering this impotence pill for your condition.
Viagra for erectile dysfunction
In order to understand the working mechanism of Viagra in treating erectile dysfunction, you must first understand how a normal erection occurs. When a man fantasizes or receives physical stimulation of the penis, his brain gets aroused and sends a signal to the smooth muscles around the penis. Nerve cells in the corpora cavernosa (the two chambers in the penis) then start producing nitric oxide, which increases the production of cGMP. It causes dilation of the blood vessels in the corpora cavernosa to increase the flow of blood to the penis. As blood enters the two penile chambers, they expand and produce an erection. The blood valves present in the cavernosa chambers prevent blood from flowing out again. This helps in sustaining an erection until ejaculation during sexual intercourse.
But the problem arises when an enzyme phosphodiesterase type 5 breaks down cGMP and obstructs the normal erection process. Viagra, being a PDE-5 inhibitor medication, works by blocking the action of this enzyme to maintain the level of cGMP intact. This medication belongs to a class of impotence pills that can be taken only on prescription. So it is advisable to first get your condition diagnosed by a doctor to get a prescription for an appropriate dose of this medication. The available doses of this impotence pill are Viagra 25mg, Viagra 50mg, Viagra 100mg.
