The objective of this study was to determine the effects of treatment on the effect of sildenafil citrate (Viagra) on the erectile response of male rats with erectile dysfunction. Male Sprague-Dawley rats were treated orally with sildenafil citrate (Viagra) or vehicle for three days (3 and 12 h). After the third day of treatment, the erectile response to the drug was studied. Male Sprague-Dawley rats treated with sildenafil citrate for up to 12 h (3 and 12 h) had a significantly lower incidence of adverse events (ejaculatory latency time (EAT)) and a significantly longer duration of erection than those treated with vehicle (0 and 1 mg/kg, respectively). Sildenafil citrate treatment significantly improved the incidence of adverse events (EAT) in male Sprague-Dawley rats treated with sildenafil citrate (3 and 12 h) compared to the vehicle-treated rats (3 and 12 h). In addition, sildenafil citrate treatment significantly reduced the duration of erection of the rats by up to 30% (p < 0.001) compared to the vehicle-treated rats. However, the treatment with sildenafil citrate significantly improved the duration of erection in the rats with erectile dysfunction.
Key:ABSTRACT
Background:Sildenafil citrate has been shown to be effective in treating erectile dysfunction by enhancing the phosphodiesterase type 5 (PDE5) enzyme. Erectile dysfunction is the inability to achieve or maintain an erection sufficient for sexual intercourse. PDE5 is a key enzyme that regulates blood flow and is activated by prostaglandins. Sildenafil citrate is thought to exert its action on the PDE5 enzyme, thereby increasing the enzyme’s activity. However, the effect of sildenafil citrate on the PDE5 enzyme has not been tested.
Method:The effects of sildenafil citrate (Viagra) on the EAT of male rats with erectile dysfunction were evaluated using the rat test model. After the third day of treatment, the EAT of the treated rats was determined. After the third day of treatment, the rats were sacrificed. Male Sprague-Dawley rats were either treated orally with sildenafil citrate (Viagra) or vehicle for up to three days (3 and 12 h). Male Sprague-Dawley rats were pretreated with vehicle or sildenafil citrate (Viagra) for three days (3 and 12 h). The rats were then used to perform the experiment.
Results:In the rats treated with sildenafil citrate (Viagra) for up to three days, sildenafil citrate significantly reduced the incidence of adverse events (EAT) in the rat test model. In addition, sildenafil citrate significantly improved the incidence of adverse events in the rats with erectile dysfunction.
Conclusions:The effects of sildenafil citrate on the EAT of male Sprague-Dawley rats with erectile dysfunction were dose-dependently improved. The treatment of sildenafil citrate (Viagra) increased the PDE5 enzyme activity, which was associated with the inhibition of the phosphodiesterase type 5 (PDE5) enzyme. These results support the concept that sildenafil citrate may exert its action on the PDE5 enzyme.

This information is not intended as medical advice and potential treatment.When the time of the Viagra-like erection is remembered, it’s a common occurrence. But for most men, the erection lasts four hours, so it’s hard to imagine that it could last more than that. And if you do happen to pop the pills, you might get a boner that lasts a lot longer.
One reason that Viagra-like erection lasts longer than a normal erection is because it can’t be taken as a real erection. In this case, the medication has a lot to do with your ability to get and keep an erection. That means that it doesn’t have an impact on your ability to keep a hard, erect penis. And for the average person, the erection lasts four hours, so it’s hard to imagine that it could last more than that.
As a result, Viagra-like erection lasts longer than a normal erection, and men who use it frequently may be embarrassed to talk about it. So, what are the risks? What about people who take it too much? And if it’s taken too frequently, they might not be able to keep a hard erection for as long as they need it.
A man who’s ever been in a relationship with an erection can get an erection, but it can’t be sustained. It’s not always the case that men who have an erection have a problem with their ability to get an erection.
The Viagra-like erection has an effect that lasts four hours and can be so long that it’s hard to imagine that it could last longer than a normal erection. That’s because it can’t be sustained. If it’s taken too much, you might end up having to try and hold onto your erection for an hour or two before popping the pills.
There are some men who will have an erection that lasts for a long time. So if you do happen to take Viagra-like erection medication, it’s important to know that it’s not safe for everyone. And for those who do take it frequently, it’s a very different experience. So if you’re not sure about the risks, talk to your doctor about what’s right for you.
If you’re taking Viagra-like erection medication, it’s important to know that the drug can interact with other drugs you take, like,, and. These drugs can make you more susceptible to heart problems, heart attacks, and strokes. They can also have other effects on your ability to get an erection, including,,, and.

Men in the UK will be able to buy Viagra over the counter after consulting with a pharmacist and without a prescription for the first time today.
ViagraConnect manufacturer, Pfizer, estimates more than a fifth of men aged over 18 in Britain suffer from erectile dysfunction, but almost half of those over 40 have not sought medical help.
The erectile dysfunction drug will be available in 14,000 stores across Britain and via pharmacy websites.
The tablets will be available exclusively from Boots until 10 April.
Those aged 18 and over will be able to buy the tablets following a conversation with a pharmacist or after filling out an online form. Men can ask to speak to a pharmacist in a private consultation room if preferred.
The pharmacists will determine whether treatment is appropriate for the patient and give advice on erectile dysfunction, usage of the medicine and potential side effects. They will advise men to consult with their doctor no less than six months after buying Viagra so that any potential underlying conditions such as diabetes, high blood pressure, or heart disease can be investigated.
A Boots spokesperson said that the man affected by erectile dysfunction should buy the drug themselves wherever practically possible.
Men with severe heart problems, those at high risk of heart problems, liver failure, kidney failure, strokes or those taking certain other medicines, will still need to be prescribed the drug under the supervision of a doctor.
A four-pack of the tablets will cost £19.99 and an eight-pack £34.99.
Men who buy it will be advised that they can take a 50 mg tablet an hour before having sex, but should not use more than one pill a day.
Viagra is is already available as an NHS prescription free of charge for those eligible not to pay for their prescriptions.
The pharmacist will decide how many packs will be supplied in a transaction.
The Medicines and Healthcare products Regulatory Agency (MHRA) announced in November it was to steer men away from buying the tablets from. In 2016 £17m worth of unlicensed and counterfeit Viagra was seized.
Kristie Sourial, Pfizer’s medical manager, said: “It’s important to remember that erectile dysfunction is a medical condition, and that the impact often goes beyond the physical symptoms – it can lead to men feeling anxious, depressed and lacking in confidence.
“Our hope is that the availability of Viagra Connect in pharmacies will encourage men who do nothing about their erectile dysfunction to seek help, and encourage those who are inclined to seek help to do so sooner.”
Viagra tablets are controlled substances and are not abused. They may be made available for sale for men who suffer from erectile dysfunction no less than six months after buying the drug.Read more
