Sildenafil Citrate 100mg: short information

sildenafil citrate - generic viagra

Viagra is a brand-name of erectile dysfunction medication Sildenafil Citrate. This drug belongs to the class of PDE-5 inhibitors and is used to deal with erectile dysfunction, or male impotence. This medication works when a man is sexually excited, but it doesn't cause sexual arousal itself. So, this medication can provide its effect when a man is sexually aroused.

In order to understand how Sildenafil works, we should discuss the mechanism of getting an erection. When a man is sexually stimulated and aroused, a certain substance is released in the erectile tissue which is called nitric oxide. This substance stimulates an enzyme that releases another substance known as cyclic guanosine monophosphate, which in its turn relaxes the cells of smooth muscle. This causes the arteries in the penis to widen and as the result, the blood flows into the penis more easily. One more effect of the medication is that it cases the erectile tissue itself to fill with blood. As a result, erection arouses.

If a man is not sexually aroused, the brain will not provoke the release of nitric oxide and the body will not produce cyclic guanosine monophosphate.

Sildenafil Citrate is used by a great number of men suffering from erectile dysfunction as it has shown that it works safe and effectively and provide a good result in dealing with impotence.

One should remember, though, that this drug is not indicated for everyone.

This medication might cause some side effects. Sildenafil can lower blood pressure in some people. Usually this drop of pressure is not significant and causes no serious health problem. Nevertheless, its effect can be raised if it is taken along with nitrate medications, usually prescribed for heart conditions. In some cases the combined use of both of these drugs can lead to serious health problem and even can be fatal.

One of the most widely asked questions is whether Viagra can be used in people with a heart condition.

Patients who have a heart condition should discuss the use of Sildenafil Citrate with the medical professional. One should remember that medication might cause serious interactions with nitrate medications, commonly used for a heart condition.

People also frequently ask if Viagra can be used by women. The answer is that it is not indicated for the use in women, but only for treating erectile dysfunction in males.

Viagra starts its action within an hour after you administer it and remains effective for 4-6 hours. Nevertheless, if it is taken with high-fat food, it might take longer for the medication to become effective.

Sildenafil is available in the following doses:
-25 mg
-50 mg
-100 mg

The right dose should be determined by the medical professional taking into the consideration the existing health conditions and the use of other medications. Besides, the doctor will take into the account the age of the patient and the severity of erectile dysfunction.

Remember that Viagra may not show its effect the first time when you take it. Usually, it is recommended to take Viagra several times before choosing some other medications.

ED medication can provoke certain side effects which are generally mild and go away soon. Among the most widely spread side reactions associated with the use of Viagra are headache and facial flushing. Among the less frequent side effects are stomach problems, a blocked nose and a blue tint to the vision.

Apart form nitrate medications, Viagra can also interact with the following drugs:
- nitroprusside
- erythromycin
- mibefradil
- cimetidine
- rifamycins
- antifungals
-alpha blockers

This is not the full list of medications that can cause interactions when used together with Viagra.


Impotence is a very common male sexual problem that affects approximately 2.3 million men in the UK. It's estimated that one in ten men will suffer from erectile dysfunction at some point in their life. Impotence can afflict men of any age, whether it's a young man feeling nervous or anxious about his sexual performance or an older man who has an illness that causes impotence.

It might come as a relief to learn that impotence is usually temporary. Thanks to effective impotence treatments, men can overcome erectile dysfunction. Oral medications such as Viagra, Cialis and Levitra, as well as talking therapies and counselling are proven to be effective impotence treatments.

Defining impotence

sildenafil citrate 100mg online

Impotence describes a medical condition where a man is unable to achieve or maintain an erection in order to complete satisfactory sexual intercourse. This can include an inability to get an erection when aroused, or it could mean that you lose your erection before or during penetration.

If you experience this several times within a short period of time, you should seek medical help. An appointment with a doctor, or a quick online consultation, can establish whether you're suffering from impotence and help you explore the best ways of treating the condition.

What's going wrong?

The mechanics of an erection is somewhat complicated. When you're aroused, your brain tells the blood vessels in your penis to relax so more blood can flow to the chambers of the penis. This engorges the penis and it becomes erect.

To get rid of an erection, the body releases an enzyme called PDE-5. This breaks down the chemical that tells the vessels in the penis to relax, and they begin to constrict again. This causes you to lose your erection.

Impotence happens when your body either doesn't produce enough of the chemical that tells the blood vessels to relax, or when your body has so much PDE-5 that it works too quickly to break down an erection.

What causes impotence?

It's important to know what causes impotence, so you can find the right treatment for it. It's estimated that 70% of cases have a physical cause and 30% have a psychological cause, though often the cause is a combination of both.

Short term causes of impotence tend to be psychological, such as depression, stress or anxiety. If your impotence is prolonged, it's probably the result of a physical problem such as a medical condition or an unhealthy lifestyle. The easiest way to understand whether it's a psychological or physical problem is to find out if you wake up with an erection in the morning or if you can sustain an erection when masturbating. If you do, the problem is not physical.

Psychological causes include guilt, depression, anxiety, stress, exhaustion, conflict with your partner, unresolved sexual orientation and sexual boredom. Physical causes include diabetes, smoking, alcoholism, deterioration of arteries, obesity, specific medications, cerebral or spinal cord injuries and abdominal or prostate surgery.

What treatment options are there?

If you think your impotence problem has a psychological cause, you will probably benefit from counselling or psychotherapy, either online or in person. It might involve couple's counselling, you discussing the problem with your partner or simply talking through your worries with a professional.

If a physical problem is believed to be the cause of your impotence, your doctor can run a number of tests to determine the best course of action.

Prescription impotence treatments

Oral prescription medications are the most popular erectile dysfunction treatment available. They encourage more blood to flow to your penis by restricting the work of the PDE-5 enzyme, but they work in different ways.


This was the first impotence treatment sold, and has helped an estimated 20 million men to enjoy a healthy sex life. It needs to be taken 30 minutes before sex and lasts for up to four hours.


Cialis is nicknamed the weekend pill, because it lasts for up to 36 hours. It takes just 30 minutes to work and gives greater sexual spontaneity. Men who suffer from persistent impotence can take a lower dosage of Cialis every day to help them achieve and sustain frequent erections.

Cialis Daily

Cialis Daily contains a lower dosage of Cialis and can be taken every day. After a couple of days of using Cialis Daily, men with long-term impotence issues will be able to achieve an erection whenever they're sexually stimulated. The low dosage means it's suitable for men over 50 and for those with underlying health issues


Levitra has been proven to work better on older men and those with existing medical conditions such as diabetes, high cholesterol and high blood pressure.

Levitra Orodispersible

This is the newest impotence treatment that dissolves on your tongue. Levitra Orodispersible comes in discreet packaging that you can carry in your pocket. Simply dissolve a tablet on your tongue and you'll be able to achieve an erection in as little as 25 minutes after taking it.
