VIAGRA is a treatment for adult men with erectile dysfunction, sometimes known as impotence. This is when a man cannot get, or keep a hard, erect penis suitable for sexual activity. Yes, particularly stress in a relationship or around sexual activity can cause erections to fail. Erections are usually stronger in men who are relaxed, rested, and comfortable with their partners.

Please Click Accept to give answer credit so I am compensated for time and expertise. Answers for informational purposes only, not to replace your physician advice or visit. Enjoy the benefits of stronger and longer-lasting erections with your partner. This medicine is a multi-color (2), oval, film-coated, tablet imprinted with "PFE or logo and NK" and "3CL".
Viagra helps to increase blood flow to the penis so that a man can get and keep an erection. It is also used to treat pulmonary arterial hypertension (PAH), a type of high blood pressure that affects the heart and lungs. Common side effects of Viagra include headache, facial flushing, indigestion, stuffy or runny nose, and dizziness. It works by increasing blood flow to the penis and helping men maintain an erection.
But your doctor might prescribe a lower starting dosage of 25 mg depending on several factors. A review of population subgroups demonstrated efficacy regardless of baseline severity, etiology, race and age. Sildenafil at steady state, at a dose not approved for the treatment of erectile dysfunction (80 mg t.i.d.) resulted in a 50% increase in AUC and a 42% increase in Cmax of bosentan (125 mg b.i.d.). The most common adverse reactions reported in clinical trials (≥ 2%) are headache, flushing, dyspepsia, abnormal vision, nasal congestion, back pain, myalgia, nausea, dizziness, and rash. VIAGRA has systemic vasodilatory properties and may further lower blood pressure in patients taking anti-hypertensive medications.
This can cause unpleasant side effects, including dizziness, headache and feeling sick. If you have taken more than 100mg of sildenafil in one day, seek medical attention. It is important to note that higher strength tablets will not work any quicker than the lower strengths, nor will it last for longer.
In studies with healthy volunteers of single doses up to 800 mg, adverse reactions were similar to those seen at lower doses but incidence rates and severities were increased. Analysis of the safety database from controlled clinical trials showed no apparent difference in adverse reactions in patients taking VIAGRA with and without anti-hypertensive medication. This analysis was performed retrospectively, and was not powered to detect any pre-specified difference in adverse reactions. Counseling of patients about the protective measures necessary to guard against sexually transmitted diseases, including the Human Immunodeficiency Virus (HIV), may be considered. However, there are no controlled clinical data on the safety or efficacy of VIAGRA in patients with sickle cell or related anemias. For example, a study conducted at McMaster University examined the effect of sildenafil on erectile function in men with diabetes mellitus.
Viagra must not be used where sexual activity is inadvisable (e.g. men with severe heart disease such as unstable angina or severe heart failure). It must also not be taken by patients who have ever had loss of vision because of a problem with blood flow to the nerve in the eye (non-arteritic anterior ischemic optic neuropathy or NAION). For the full list of restrictions, see the package leaflet.
Do not use VIAGRA in patients who are using a GC stimulator, such as riociguat. PDE5 inhibitors, including VIAGRA, may potentiate the hypotensive effects of GC stimulators. VIAGRA is contraindicated in patients with a known hypersensitivity to sildenafil, as contained in VIAGRA and REVATIO, or any component of the tablet. Hypersensitivity reactions have been reported, including rash and urticaria [see Adverse Reactions (6.1)]. The most common are headache, flushes of blood to the face, dyspepsia (upset stomach), nasal congestion and visual disturbances. Do not take Viagra with similar medications such as avanafil (Stendra), tadalafil (Cialis) or vardenafil (Levitra).
A doctor will let you know if you need a lower dose for safety reasons, which is more likely as you get older but varies on a person to person basis. As you get older your body gets less efficient at removing Viagra from your system, so your dose may last longer. But, as you get older, your erectile dysfunction symptoms may get worse so a higher dosage might be needed.
In most cases the fee is $40 but varies by treatment category. The visit fee includes a prescription valid for up to a year (depending on the condition) and on-going support from the healthcare practitioner or pharmacist. It can also interact with many other medicines, particularly nitrates (used in heart disease), amyl nitrite and blood pressure medicines.
It’s also important to store Viagra correctly and to not take expired medication. Storing Viagra at room temperature and away from moisture, heat, and sunlight will help make sure the medicine has the most extended shelf-life possible. The prescribing information recommends a maximum of one dose per day.
The tablet should be taken without food and alcohol intake should be limited. Note that the tablet will only work in combination with sexual stimulation and arousal. No more than one erectile dysfunction treatment should be taken at once and there should be a 24 hour break period between each tablet, or 36 hours for Tadalafil and Cialis. Viagra Connect is a PDE5 inhibitor and is taken daily when required, 1 hour before sexual intercourse, at a dose of 50mg. Sildenafil is the active ingredient of the branded medication called Viagra.
(An active ingredient is what makes a drug work.) Viagra belongs to a group of drugs called phosphodiesterase 5 (PDE5) inhibitors. The use of VIAGRA offers no protection against sexually transmitted diseases. VIAGRA is rapidly absorbed after oral administration, with a mean absolute bioavailability of 41% (range 25–63%). The pharmacokinetics of sildenafil are dose-proportional over the recommended dose range. It is eliminated predominantly by hepatic metabolism (mainly CYP3A4) and is converted to an active metabolite with properties similar to the parent, sildenafil.
The strongest dose of Cialis is 20mg while the strongest Viagra pill is 100mg. Cialis contains the active ingredient tadalafil whereas Viagra contains sildenafil citrate. Both drugs are from the PDE5 inhibitors category of medications and work in the same way. What works well for you might not work well for someone else with ED. The availability of different sildenafil citrate dosages allows prescribers to level up and down where required.
Dosage will depend on what your healthcare practitioner believes is the best choice for you. The most common dosages are 50mg or 100mg, but in some cases, 25mg doses are used. Sildenafil is a medicine used to treat erectile dysfunction (ED, also called impotence). It is sometimes known by its generic name sildenafil, and sometimes known by its trade name Viagra. In rare cases, Viagra can cause a sudden hearing impairment or loss, which may include ringing in the ears or dizziness. If you have any of these symptoms, stop taking Viagra and consult your healthcare provider right away.
Sildenafil is the name of the drug that is contained in Viagra. Viagra is just a popular brand of sildenafil, however other manufacturers make the same drug in a tablet at a much cheaper price. Female sexual dysfunction (FSD) is incredibly common, with up to 50% of women suffering from some form of FSD. While some struggle to become sufficiently lubricated for sex or feel a lack of sexual desire, others find they’re unable to achieve orgasm or feel pain during intercourse.
It also includes certain illegal drugs called poppers, such as amyl nitrate. For instance, some interactions can interfere with how well a drug works. Other interactions can increase side effects or make them more severe. Viagra is approved for use in males ages 18 years and older.
If you’re taking Viagra and have an erection that lasts longer than four hours (priapism), you should get emergency medical help as soon as possible. If you’re experiencing prolonged erections regularly, it’s best to talk with your healthcare provider about whether or Viagra not continuing to take Viagra is right for you. Viagra has been popular for decades, and recently Pfizer’s patent for the drug expired – allowing a generic unbranded medication, Sildenafil, to be produced and sold by accredited online pharmacies. Sildenafil is the active ingredient in Viagra, so it’s exactly the same – aside from the brand name. This means it can be taken just as often as Viagra – every day, if you’re seeking the desired effects this often.
This medication can help you get an erection up to 36 hours after you’ve taken a dose. Viagra contains the drug sildenafil, while Cialis contains the drug tadalafil. Both Viagra and Cialis belong to a group of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Also keep in mind that certain side effects occur more often with higher doses of Viagra.
This is the biggest difference in approved dosages of Cialis compared with Viagra. The highest recommended Viagra dose for treating erectile dysfunction (ED) is 100 mg per day, according to the drug’s manufacturer. Doses of 150 mg or 200 mg would be considered off-label use. "Off-label" is when a drug is prescribed to treat a condition it isn’t approved to treat, or in a dose that’s not approved by the Food and Drug Administration (FDA). You can take the drug 30 minutes to 4 hours before you anticipate sexual activity. In fixed dose studies, the proportions of patients reporting that treatment improved their erections were 62% (25 mg), 74% (50 mg) and 82% (100 mg) compared to 25% on placebo.
It belongs to a group of medications called phosphodiesterase type 5 (PDE5) inhibitors, which work as vasodilators and cause blood vessels to relax. Viagra can’t permanently cure ED, but it can help in the short-term and is safe to take every day if approved by a doctor. After taking Viagra, most men will be able to maintain an erection for about two to three hours before the effects start to wear off. Viagra is not available over-the-counter and must be prescribed by a physician.
Take this medication about 30 minutes before sexual activity, or when your doctor recommends. As research into female Viagra is limited and the effects of taking the drug are not well established, Viagra isn’t recommended for FSD and it’s not a good idea to take it. However, there are a number of safe, medically approved alternatives that could help improve your sexual function.
At this dose you and your doctor can monitor your physical reaction to the medicine and address any possible side effects early on. But, if it is well-tolerated and only mediocre results are reported, men are then often upgraded to sildenafil 100mg. If your symptoms or health problems do not get better or if they become worse, call your doctor. Do not share your drugs with others and do not take anyone else's drugs. Keep a list of all your drugs (prescription, natural products, vitamins, OTC) with you. Talk with your doctor before starting any new drug, including prescription or OTC, natural products, or vitamins.
Some people may experience side effects other than those listed. Check with your doctor if you notice any symptom that worries you while you are taking this medication. Contact your doctor if you experience these side effects and they are severe or bothersome. Your pharmacist may be able to advise you on managing side effects. The side effects listed below are not experienced by everyone who takes this medication. If you are concerned about side effects, discuss the risks and benefits of this medication with your doctor.
It’s 100% online and takes only 2 minutes to see your recommended treatments. Viagra tablets are reportedly successful for 74% of men who try Viagra.

Viagra tablets can contain lactose, consult your doctor or prescriber if you have been diagnosed with a sugar intolerance before you buy Viagra tablets and commence treatment. Easy to say, but Viagra will only work when you are sexually aroused. Anxiety, stress, and nerves can all interfere with your response to Viagra.
Furthermore, the fact that Sildenafil is an approved ED treatment and used around the globe shouldn’t deter you from reading the accompanying patient information leaflet the first time you use it. Both medications are phosphodiesterase type 5 (PDE5) inhibitors that work by increasing blood flow to the penis. If you experience any of these symptoms, seek immediate medical attention. Viagra is a type of erectile dysfunction (ED) treatment for men that’s taken about 60 minutes before sex.
Paxlovid may cause allergic reactions, which can be serious. Stop taking Paxlovid and get help right away if you have any of the following symptoms of a serious allergic reaction. While less common, the most serious side effects of Paxlovid are described below, along with what to do if they happen.
Viagra belongs to a class of medications called phosphodiesterase-5 (PDE-5) inhibitors. It works by temporarily increasing the blood flow to your penis, helping you to get and maintain an erection. Regarding which medication allows an erection to last longer, the clear winner is tadalafil. Sildenafil remains effective for four to six hours, while tadalafil will enable patients to achieve erections up to 36 hours after ingestion, an effect usually seen in younger patients or lesser degrees of ED. In both cases, the drug does not increase desire, instead allowing for a better erection when the desire is present.

But if you take it with a meal, the drug may take about an hour longer than usual to start working. This is especially the case if you eat a high fat meal, such as a cheeseburger with fries. Grapefruit juice can affect the levels of some medications in your body. But there’s not much evidence to show that the fruit or its juice can affect Viagra levels.

There are certain fruits that might be hurting or helping your erections without you realising. If you want to show your partner that they really are the apple of your eye, then find out which fruits can transform your sex life.

We at the McGuff Company, Inc. (McGuff) work very hard to provide you accurate and timely information on our website. However, it is your obligation to verify such information before using the products purchased from McGuff. The total body clearance of sildenafil is 41 L/h with a resultant terminal phase half-life of 3-5 h. Grapefruit juice is a weak inhibitor of CYP3A4 gut wall metabolism and may give rise to modest increases in plasma levels of sildenafil.
The pharmacokinetics of sildenafil in patients with severely impaired hepatic function (Child-Pugh Class C) have not been studied. A starting dose of 25 mg should be considered in patients with any degree of hepatic impairment [see Dosage and Administration (2.5) and Clinical Pharmacology (12.3)]. Co-administration of ritonavir, a strong CYP3A4 inhibitor, greatly increased the systemic exposure of sildenafil (11-fold increase in AUC). It is therefore recommended not to exceed a maximum single dose of 25 mg of VIAGRA in a 48 hour period [see Dosage and Administration (2.4), Warnings and Precautions (5.6), Clinical Pharmacology (12.3)]. Use caution when co-administering alpha-blockers with VIAGRA because of potential additive blood pressure-lowering effects. Prolonged erection greater than 4 hours and priapism (painful erections greater than 6 hours in duration) have been reported infrequently since market approval of VIAGRA.
On average across all three doses, Viagra takes 30 minutes to 1 hour to start working. Higher doses take slightly longer to reach their maximum strength inside your body, but this difference is fairly small. However, the dose can be increased to 100mg or lowered to 25mg based on how it works for you. Take Sildenafil about 4 hours before having sex for best results. If after eight attempts Sildenafil 50mg still doesn't provide the desired results, consult your doctor about adjusting the dosage or exploring alternative medications like Tadalafil (Cialis). Always consult your doctor before making any changes to your treatment.
An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed. The following side effects have been reported by at least 1% of people taking this medication. Many of these side effects can be managed, and some may go away on their own over time. Nitrates are found in medications that are used to treat angina (chest pain). If you are not sure if you are taking nitrates, ask your doctor or pharmacist.
Concurrent use of Viagra and these medications can lower blood pressure leading to falls, injuries, and other complications. Men taking an HIV drug called ritonavir (Norvir) may also need to take a lower dose of Viagra. Viagra is available in 25 mg, 50 mg, and 100 mg tablets to treat erectile dysfunction. Typical dosages are 25 mg and 50 mg as needed 1 hour before sex. Drinking alcohol can temporarily weaken your ability to get an erection and may increase the blood pressure lowering effects of the medication, which can be dangerous.
Higher strength tablets are more likely to produce a response where there has been no response to the lower strengths. If sildenafil 25mg does not work and you are taking sildenafil for the first time, try taking it again. Current guidelines state that you should take the tablets on 8 separate occasions, before thinking about increasing the dose. You should discuss this with your pharmacist or doctor beforehand. If you are taking sildenafil 25mg to reduce side effects after having taken the 50mg tablets, follow the same advice. If you are still not experiencing the desired effect with the 25mg tablets, you may wish to speak to your doctor or pharmacist about an alternative treatment.
There may be slight differences in the other ingredients, such as the binding agents (what holds the drug into place) and the colouring. However, we can also obtain Pfizer, Mylan, Bristol, Dr Reddy, Sandoz, Actavis and Torrent brands. If you wish to obtain a certain generic brand, please make a note of this on your consultation form. The typical starting dose is 50mg taken as needed, about 1 hour before sexual activity. Based on effectiveness and tolerability, the dose may be increased to 100mg or decreased to 25mg. They’re the two most well known ED drugs, so it’s common for men to compare Cialis and Viagra when trying to decide what will work best for them.
Most, but not all, of these patients had preexisting cardiovascular risk factors. Many of these events were reported to occur during or shortly after sexual activity, and a few were reported to occur shortly after the use of VIAGRA without sexual activity. Others were reported to have occurred hours to days after the use of VIAGRA and sexual activity.
Sildenafil is available in three doses; 25mg, 50mg and 100mg. The higher the dosage, the stronger its effects but this can also mean you’re more likely to experience side effects. Your healthcare provider may start you on a lower dose to see how you tolerate the drug before increasing your dose. Even if you don’t get it quite right the first time, your healthcare provider will help you find a dose that’s right for you.
Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. These events have been chosen for inclusion either due to their seriousness, reporting frequency, lack of clear alternative causation, or a combination of these factors. In placebo-controlled clinical studies, the discontinuation rate due to adverse reactions for VIAGRA (2.5%) was not significantly different from placebo (2.3%).
It should be kept in a tightly sealed container away from light. Avoid storing this medication in areas where it could get damp or wet, such as in bathrooms. When you get Viagra from the pharmacy, the pharmacist will add an expiration date to the label on the bottle. This date is typically 1 year from the date they dispensed the medication. And keep in mind that sexual problems can be related to reduced sexual desire and arousal.
It is generally recommended to limit alcohol consumption while using Viagra. Alcohol can impair sexual performance and increase the risk of side effects like dizziness and headaches. Excessive alcohol intake may also reduce the effectiveness of Viagra.

While Viagra isn’t approved for use in females, a drug called Addyi is approved for use in certain females. Below, we describe the condition Addyi is approved to treat and how the drug works. In males, Viagra improves blood flow to the penis by blocking the action of a chemical called PDE5. This chemical is also found in the vagina and the clitoris of females.
Other drugs are available that can treat erectile dysfunction (ED). If you’re interested in finding an alternative to Viagra, talk with your doctor. They can tell you about other medications that may work well for you. For example, people ages 65 years and older tend to get higher levels of Viagra in their blood after taking a dose.
There have been reports of heart attack, stroke, irregular heartbeat, bleeding in the brain or lungs, high blood pressure, and sudden death in men who took sildenafil for erectile dysfunction. Most, but not all, of these people had heart problems before taking sildenafil. It is not known whether these events were caused by Sildenafil Online, sexual activity, heart disease, or a combination of these and other causes.Talk to your doctor about the risks of taking sildenafil.
Here’s what you need to know about the dangers of recreational Viagra use. If you have heard about ‘female Viagra’, it is probably referring to a medicine called flibanserin (also known by its brand name, Addyi). This medicine has been approved in the United States to treat premenopausal females who have low sexual desire. Because Cialis and Viagra are both PDE5 inhibitors, they have similar side effects and safety concerns. Talk with your healthcare provider about which might be best for you. Nitric oxide is a substance that causes blood vessels to relax.
Sildenafil helps relax the blood vessels at the base of your penis, improving blood flow and helping you get harder erections when you’re aroused. VIAGRA 100MG tablets contain sildenafil, a medication used to treat erectile dysfunction (ED) in men. Sildenafil works by increasing blood flow to the penis, helping to achieve and maintain an erection when sexually aroused. Sildenafil can be taken every day, up to the recommended maximum dosage of 100mg. It helps men with erectile dysfunction enjoy more adventure and freedom – because it is a highly-effective and minimally-disruptive medication that can get to work in less than an hour. Viagra is a prescription-only medication that is used to treat erectile dysfunction (ED) in men, and works for around 74% of men who try it.
It’s important to note that sexual stimulation is still needed for Sildenafil to function. Keep all your medications out of the reach of children and pets and return any unused or expired medications to the pharmacy for proper disposal. When recommending a phosphodiesterase-5 inhibitor, it is essential to discuss the likely effects as patients can have unrealistic expectations.
The Patient Information Leaflet enclosed with your medicine will detail a full list of side effects. Below, we’ll cover everything you need to know about Spedra, answering any questions you may have about the ED treatment to help determine if it’s right for you. A Felix online visit is considered asynchronous since it is conveniently completed through a secure chat bases system.
Although most ED medications are rigorously tested, studied, and approved before reaching drug stores, they all come with a risk of side effects. Always tell your healthcare provider about any prescription or over-the-counter (OTC) medicines, vitamins/minerals, herbal products, and other supplements you are using. Sildenafil and Viagra tablets both have the same side effects, do not take more than one each day and do not take both at the same time. The main difference between Sildenafil and Viagra tablets is price, Viagra tablets are expensive in comparison. This is due to Viagra tablets being branded, whereas Sildenafil is the generic medication but works in the exact same way.
Avanafil is the active ingredient in Spedra tablets which tackles ED. It is a PDE-5 inhibitor — a drug that increases the blood flow to your penis once you have become aroused. This blood flow will only occur during sexual stimulation; using Spedra doesn’t mean you will achieve an erection as soon as you take the tablet.
Some experts recommend taking Viagra on an empty stomach, while the prescribing information notes that Viagra can be taken with or without food. Either way, both agree that you should not take Viagra after a high-fat meal. If you’re taking Viagra regularly, it may be a good idea to keep track of what works best for you. Luckily, most men experience no side effects when they take Sildenafil or Tadalafil. If sildenafil 50mg has worked, but you have experienced side effects, sildenafil 25mg can provide the same effect, with a lower chance of side effects. Most people who have taken Viagra will eventually turn to sildenafil, as it is a cheaper option that provides the same results.
Manufacture and sale of sildenafil citrate drugs is common in China, where Pfizer's patent claim is not widely enforced. Sildenafil protects cyclic guanosine monophosphate (cGMP) from degradation by cGMP-specific phosphodiesterase type 5 (PDE5) in the corpus cavernosum. The pharmacokinetics of sildenafil in patients with severely impaired hepatic function have not been studied. Maximum observed plasma concentrations are reached within 30 to 120 minutes (median 60 minutes) of oral dosing in the fasted state.
When it is ordered online an electronic prescription is involved. The only exception applies where a specialist pharmacist supplies Viagra on a pharmacist written prescription or using a 'patient group direction'. Other drug manufacturer's followed suit and also supply sildenafil 50mg OTC. In all cases only registered pharmacies are permitted to supply it. The commonly used erectile dysfunction (ED) oral treatments all work in the same way.
For a majority of men with ED, 100mg is shown to produce an optimal erection hardness (fully hard and rigid). We all want flexibility and spontaneity in our sex lives, and we want to know that we can have sex when we want it. In this way, it’s a pretty important question – and you’ll be pleased by the answer.
Learn about the causes, treatment and how to prevent complications. Find out what questions a doctor may ask when discussing erectile dysfunction (ED, or impotence). If you have impotence (erectile dysfunction), the treatment your doctor recommends will depend on the severity of your symptoms and the underlying cause of your impotence.
The typical dose of Viagra for erectile dysfunction (ED) is 50 mg. You can take this dose 30 minutes to 4 hours before you plan to have sexual activity. But for most people, it’s recommended that you take your dose about an hour before having sex. It’s also important to monitor for any adverse effects or reactions, such as blurred vision, dizziness, light sensitivity, skin rash, increased heart rate, or anything else abnormal. Keep an eye out for any unusual symptoms or side effects, and if any severe or concerning symptoms develop, seek immediate medical attention. While there are many products that claim to boost sex drive in women — including herbal supplements — there’s no direct Viagra equivalent to treat sexual dysfunction in women.
By inhibiting this enzyme, more blood can flow to where it is needed. And, with greater blood flow, the chances that you will achieve and maintain an erection increase, too. This is why medicines like Viagra – and its generic unbranded version, Sildenafil (or Sildenafil Citrate) – are both so popular and so little understood by the general population. Although ED is common, we don’t talk about it as much as we should – and if we come to need the treatments, we don’t really know what it all entails. As such, men usually have a lot of questions about the drug – and that’s perfectly normal.
Sometimes a lower starting dose of 25mg will be suggested by a clinician. This route may be considered if you’re already taking certain medications for the treatment of kidney, liver or heart conditions. Or if your previous tolerance of sildenafil citrate 50mg was low.
Do not flush unused medications or pour down a sink or drain. Sildenafil and Tadlafil do not protect against sexually transmitted diseases, including HIV.

Tell your doctor or pharmacist if the advice on how to cope does not help or the side effects get worse. Headaches should usually go away after the first week of taking sildenafil. Talk to your doctor if they last longer than a week or are severe. Common side effects of sildenafil happen in more than 1 in 100 people.
Please seek the advice of a physician or other qualified health provider with any questions you may have regarding a medical condition. Do not disregard professional medical advice or delay in seeking it because of something you have read on this website. PDE5 inhibitors like sildenafil work by blocking an enzyme called PDE5, which makes blood vessels smaller. During an erection, a natural chemical called cGMP opens up blood vessels in the penis, increasing blood flow and making the penis harder. Since PDE5 stops cGMP (therefore blocking erections), inhibiting PDE5 allows cGMP to work its magic and make erections last longer (Smith, 2021).
You may wonder how often certain side effects occur with this drug. Here’s some detail on several of the side effects this drug may cause. The following lists contain some of the key side effects that may occur while taking Viagra. If you have other questions about how long Viagra works, talk with your doctor. Since Viagra has been released onto the market, there have been a few reports of bleeding in people who have taken the drug.
In controlled clinical trials, the discontinuation rate due to sildenafil was low and similar to placebo. Therefore, concomitant administration of strong CYP3A4 inducers, such as rifampin, is expected to cause greater decreases in plasma concentrations of sildenafil. At 24 hours, the plasma levels of sildenafil were still approximately 200 ng/mL, compared to approximately 5 ng/mL when sildenafil was administered alone.

When hypertension occurs in the lungs, the heart must work harder to pump enough blood through the lungs. Sildenafil works on the PDE5 enzyme in the lungs to relax the blood vessels. This will increase the supply of blood to the lungs and reduce the workload of the heart. Rarely, sudden decreased vision, including permanent blindness, in one or both eyes (NAION) may occur.
The major circulating metabolite results from N-demethylation of sildenafil. This metabolite has a phosphodiesterase selectivity profile similar to sildenafil and an in vitro potency for PDE5 approximately 50% that of the parent drug. Plasma concentrations of this metabolite are approximately 40% of those seen for sildenafil. The N-desmethyl metabolite is further metabolised, with a terminal half-life of approximately 4 h. When sildenafil is taken with food, the rate of absorption is reduced with a mean delay in tmax of 60 minutes and a mean reduction in Cmax of 29%. In cases of overdose, standard supportive measures should be adopted as required.
