The active ingredient in Viagra is sildenafil citrate, which is a phosphodiesterase type 5 inhibitor (PDE5i). The inhibitor blocks the enzyme PDE5, which prevents relaxation of smooth muscle tissue.
Viagra contains the drug sildenafil. It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. (A class of drugs is a group of medications that act in a similar way.) Viagra works by increasing blood flow to your penis, which helps you have and keep an erection.
Viagra is a medication that helps you to get and keep an erection, so it can make you last longer in bed if you're finding it difficult to stay erect during sex. However, Viagra does not help you last longer if you're orgasming faster than you want to.
Viagra Connect, Viagra and Sildenafil all contain the same active ingredient: sildenafil citrate. Sildenafil citrate is a chemical that temporarily increases blood flow to the penis, enabling an erection when sexually aroused.
Although it can be taken with or without food, Viagra tends to work best when taken on an empty stomach. So, to maximize its effects, try to take it separately from meals.
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.
Cialis has comfortably the longest effectiveness period of any erectile dysfunction drug on the market.
Both drugs are equally powerful. Some people prefer Cialis vs. Viagra because of its longer effect (up to 36 hours). Others may prefer the once-daily dosing of Cialis as a longer-term solution for erectile dysfunction that allows more spontaneity in their sex lives.
Because 100mg is the highest dose available, you should never 'double up' on tablets or take more than one in 24 hours. Sildenafil 100mg is the highest safe dosage you can take – if it is ineffective, you should try another ED treatment.
It relaxes the smooth muscles and arteries inside the penis. At the same time, it increases blood flow to the penis. When aroused, this combination of relaxation and increased blood flow allows the penis to fill with blood, which results in an erection. Good to know: Cialis only works if you're sexually aroused.
Sildenafil and other generic treatments like Tadalafil and Vardenafil are the cheapest erectile dysfunction pills available. These medications work the same way as branded treatments like Viagra, Cialis, and Levitra but since they aren't branded, they're usually cheaper.
What happens if a woman takes Viagra? Just as Viagra helps improve blood flow for an erection, it may improve blood flow in the female reproductive parts. When this happens, it may cause more sensitivity and stimulation, causing the person taking it to become more aroused.
Viagra will not make you come or prevent premature ejaculation. Viagra is primarily an erectile dysfunction medication and does not directly impact time to ejaculation.
Is There a Way To Tell if a Man is Taking Viagra? Wondering if your man is taking a pill to keep up his energy in bed? You could check his medicine cabinet, send an email to his doctor asking what prescription drugs he's on, or have his blood tested.
Penile implant. A penile implant involves a 30- to 45-minute surgical procedure that places a water-based device into the erection chambers of the penis, which enables you to reliably control exactly when and how long an erection lasts. Dr. Starke says this is the closest option to a cure that exists for ED.
L-citrulline and L-arginine
Some researchers believe that L-citrulline, an amino acid, can cause blood vessels to relax similarly to how Viagra works. It's the precursor of L-arginine, another amino acid that has been shown to improve blood flow (Cormio, 2011).
Using them incorrectly — having the wrong dosage or not following instructions — can cause Cialis not to work. Cialis might also fail if your ED is related to psychological issues — performance anxiety, intimacy issues, low self-confidence and depression can all affect your erections.
There are many reasons why you might not last as long as you'd like in bed. At some point or another, most men experience this feeling. You could be experiencing performance anxiety, stress, premature ejaculation, or erectile dysfunction (if you find it difficult to get or maintain an erection during sex).
Erectile dysfunction (ED) medications that can be cut in half. The most common ED medications can be safely split. This includes: Sildenafil (Viagra)
Nothing much would happen if someone without erectile dysfunction took Viagra, although they might think they feel better psychologically. But it would make a difference if you took it along with other drugs. Cocaine, marijuana, ecstasy, alcohol, nicotine, crystal meth - they all can cause erection problems.
Pfizer, the company that manufactures this drug, has confirmed that the typical Viagra user is on average 53 years old. The company does not keep records of users younger than 33 years. The drug should not be used in young men who do not have erection problems.
