Sildenafil

Sildenafil is the active ingredient present in one of the most popular erectile dysfunction medication, Viagra. It’s a prescription medication and the first drug to be approved by the FDA as an effective treatment option for erectile dysfunction. With time sildenafil has gone on to treat millions of men suffering from impotence and has changed their lives for the better. Gone are the days when men went into their shells at the mention of sex, because of their erection problems. Sildenafil, with the advent of erectile dysfunction drugs, changed the way erectile dysfunction is perceived today.

The working of sildenafil

Sildenafil belongs to a family of medications known as phosphodiesterase type 5 (PDE5) inhibitors. Sexual stimulation is needed for the sildenafil pill to begin its action. Following sexual stimulation, this impotence medication helps a person experience a firm and longer-lasting erection. It works by blocking the action of PDE5, which is an enzyme that breaks down cyclic guanosine monophosphate (cGMP) an enzyme that is responsible for the smoothing of the spongy penile tissue as well as the improvement of blood flow. The intake of sildenafil increases the levels of cGMP which leads to a dilation of the blood vessels of the penis and relaxes the penile tissues. This results in an improvement in the blood flow to the penis as well as experiencing firmer, longer-lasting erections.

Precautions

If you are allergic to Viagra, or any of the ingredients that make up Viagra, it’s advisable that you stay away from this drug. There is a group of medications known as ‘nitrates’ that is prescribed for the treatment of angina. Intake of Viagra tends to increase the effects of these medications, leading to serious health risks. Sildenafil needs to be avoided in this case. Apprise your doctor of your medical history as well as your current intake of medications before your doctor puts you on sildenafil. Extra precaution should be maintained if you suffer from a heart condition or are suffering from heart disease. Be sure to inform your doctor about the same.

Taking sildenafil

Sildenafil doses come in 3 forms namely sildenafil 25mg, sildenafil 50mg and sildenafil 100mg. Typically a doctor will prescribe the lowest possible dosage of sildenafil and increase the dosage keeping in mind the patients response to the drug. It’s important to understand that you won’t experience an instantaneous erection if you take Viagra. It takes around 60 minutes to start taking effect. The effect of Viagra lasts for around 4 hours. To optimize the use of this ED medication, you must take it on an empty stomach or after consuming a low-fat meal.
