Sildenafil citrate (often shortened to “sildenafil”) is the main ingredient in Viagra. After parent company Pfizer’s patent expired, other manufacturers were allowed to manufacture generic Viagra under the name of its active ingredient, sildenafil. The terms are pretty much interchangeable, the way you might say “Kleenex®” to refer to a tissue. The only real difference between the two medications for ED is how much they cost. Viagra® is a well-known and widely used medication for treating erectile dysfunction (ED), one of the most common sexual dysfunctions in the world. If you’re curious about the history of the brand and generic names, here’s the quick version: Two years and many clinical trials later, in March of 1998, the new medication — now called Viagra — received approval from the Food and Drug Administration and hit the market as a prescription medication for the treatment of erectile dysfunction. Two years and many clinical trials later, in March of 1998, the new medication — now called Viagra — received approval from the Food and Drug Administration and hit the market as a prescription medication for the treatment of erectile dysfunction. As the first oral medication for ED, Viagra became incredibly popular. Large-scale TV ad campaigns made the little blue pill famous. In 2005, the FDA approved sildenafil under the brand name Revatio® for treating pulmonary arterial hypertension — more on this later. Pfizer’s patent on Viagra expired in 2012 for countries outside the U.S., allowing other brands to produce and market their own generic Viagra medications containing sildenafil.

2.2 Use with Food
Formulated as that iconic little blue pill, Viagra has the longest history of any FDA-approved ED treatment on the market today. Both generic sildenafil and Viagra work by increasing blood flow to your penis, making it easier for you to get and maintain an erection. Sildenafil belongs to a class of enzyme-inhibiting drugs called phosphodiesterase type 5 inhibitors, or PDE5 inhibitors. Like the others in its class, sildenafil works by relaxing the muscle tissue inside the walls of your blood vessels, allowing the vessels to dilate, and improving blood flow throughout some parts of your body — including your penis. It's important to note that these erectile dysfunction medications aren't wonder drugs. Even though the active ingredients are the same, if you’re switching from Pfizer’s brand-name Viagra to a generic form of sildenafil, it’s important to check that you’re purchasing tablets with a similar dosage to the one your healthcare provider prescribed. Sildenafil may also be sold sildenafil tablet manforce 50 mg under different brand names in other countries. Some of these Viagra generic names include: When it comes to drugs like Figral, Mazzogran, and Fildena vs. Viagra, they are all used for the same purpose: increasing blood flow to the penis.
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Tadalafil is very specific for PDE5 and is also very specific for the enzyme PDE11. Unfortunately, we don’t know much about PDE11, which is found in the heart, in the pituitary gland in the brain and in the testicles. Pharmacokinetics, half-life, is how long the medication stay s in the blood. This means that vardenafil (Levitra) should act longer than sildenafil (Viagra) but the clinical significance is not known. Tadalafil (Cialis) has the longest half-life and allows you to take the medication and not relate the sexual activity to the immediate use of the medication.
Does Viagra increase a man’s sex drive?
The drawback is if you need nitrates after using tadalafil (Cialis), this medication lasts a long time in your blood stream and may place you at a higher risk. Younger people might do well treated with tadalafil, (Cialis) while older people with other health issues might be better sildenafil for women off using sildenafil (Viagra) or vardenafil (Levitra) but more data are needed. The side effects of vardenafil (Levitra) are potentially less than sildenafil (Viagra), but more data are needed. In a recent study on men with erectile dysfunction and diabetes, vardenafil (Levitra) improved their erectile dysfunction. Tadalafil (Cialis) is as effective as sildenafil (Viagra), and vardenafil (Levitra) with similar side effects except for back pain that occurs occasionally with tadalafil, probably because of the long half-life. Their labels also state that these products contain sildenafil, so Mazzogran sildenafil 100mg should be equivalent to brand-name Viagra 100mg. However, because these drugs have not been made in the U.S. and cleared by the FDA, it may be harder to assess the quality of their ingredients.

Sildenafil Citrate – The Best Generic of Viagra
There are many oral therapies for erectile dysfunction, but the only approved medication in the US is the PDE 5 enzyme inhibitor sildenafil (Viagra). Unapproved therapies, some of which are available in the US and some elsewhere, some of which have data to prove efficacy and some not, include tadalafil (Cialis), vardenafil (Levitra), yohimbine, phentolamine, trazodone, apomorphine and neutraceuticals. PDE5 inhibitors act to relax penile erectile tissues with sexual stimulation thus enhancing your ability to get an erection. Sildenafil (Viagra) is effective for all sorts of erectile dysfunction in 69% of people. Why is there a need for another pill?
Is there a “female Viagra”?
In some cases the erection is not hard enough, sometimes sildenafil (Viagra) just doesn’t work. Structurally vardenafil (Levitra) is similar to sildenafil, while tadalafil (Cialis) is very different. Vardenafil (Levitra) is almost 10 times more biochemically potent than sildenafil, therefore a lower dose is needed to facilitate the penile erection, potentially resulting in less side effects. Selectivity is the ability of the drug to attach to the specific enzyme PDE 5 found in penile tissues. Vardenafil (Levitra) is more selective than sildenafil and tadalafil (Cialis) to PDE5, which again means a lower dose is needed with potentially less side effects. If you’re in the U.S. and looking for a cheaper alternative to Viagra, it’s best to stick with FDA-approved sildenafil. Viagra comes in three dosages: 25mg, 50mg, and 100mg.
