Viagra medicines are prescribed for the treatment of erectile dysfunction (ED). These are FDA-approved medicines that improve the erection function.
They come in the form of tablets of three different doses, including 25 mg, 50 mg, and 100 mg. Your doctor will prescribe a suitable dose for your condition. In this blog, we will see how Viagra produces its effects.
Viagra is a vasodilator medicine, that targets the constrictions of the penile blood vessels. Constrictions cause the narrowing of the blood vessels and prevent blood flow to the penile. This causes erection difficulties.
Sildenafil Citrate is the active component of Viagra medicines. It performs the key function, which is to increase the blood supply to the penile. This component is a phosphodiesterase type 5 (PDE5) inhibitor, that performs vasodilation in the penile.
Vasodilation increases blood flow in the penile blood vessels, thereby restoring the erection function. Vasodilation is a result of the release of nitric oxide in the blood vessel walls.
Viagra effectively expands the blood vessels. In turn, it boosts the blood supply to the penile, which causes stronger erections. Viagra alternatives like Fildena also produce the same effects. Both these contain the same active ingredient, which is Sildenafil citrate.
Individuals having erectile dysfunction fail to get erections. Their penile remains feeble even after complete sexual arousal. However, Viagra overcomes this difficulty. It produces stronger erections.
The function of Viagra is to enhance the flow of blood to the penile. It conducts vasodilation in the penile shaft. The blood vessels dilate as a result. This happens as the muscles of the blood vessels relax.
Vasodilation relieves muscle tension and expands the blood vessels. This reduces the pressure with which blood is flowing inside the passages of the vessels. The blood vessels carry adequate blood to the penile chambers.
The penile chambers fill with blood. The blood then gets trapped inside the penile under high pressure. As a result, the penile attains erection and appears bigger and longer in size. It turns harder and gets raised above. After ejaculating, it returns to its normal size and position.
Viagra makes your penile bigger: Viagra does not cause your penile to grow in size. It increases the blood flow inside the penile to trigger firmer erections. The increase in blood flow engorges the penile with blood.
The blood then gets trapped in the penile shaft under great pressure. This leads to erection. The erection thus attained will make the penile appear bigger than its usual size.
Viagra causes spontaneous erections: Viagra does not trigger erections spontaneously. It produces its effects only in the presence of sexual arousal. Sexual stimulation is essential for Viagra to obtain its required outcomes.
After taking the pill, it will take around 30 minutes to an hour for the effects of Viagra to become active in the bloodstream. The effects continue to remain active, but the erection will happen only after arousal.
Viagra delays orgasms: There is a lack of evidence in this regard. As per some anecdotal evidence, its effects might help prolong erections, thereby delaying the orgasms.
These are common symptoms that can be of mild intensity. They disappear on their own after some time.
Drugs taken for treating chronic health conditions might lead to some dangerous side reactions after their interaction with Viagra medicine. This medicine must never be combined with drugs such as alpha-blockers, nitrates, poppers, blood pressure medicines, protease inhibitors, seizure drugs, HIV drugs, and Riociguat.
Combining Viagra and alcohol can cause a decrease in blood pressure, which can be risky. Besides, their interaction potentiates the risk of several side effects like dizziness, fainting, flushing, and headaches.
