Cialis, Levitra, Viagra: which is better, reviews. Which is better - Viagra, Cialis or Levitra

For men, erectile dysfunction is a real disaster. If you are overtaken by this ailment, the doctor will most likely advise a drug from the group of phosphodiesterase inhibitors. This family of drugs is responsible for increasing blood flow to the penis, thereby increasing potency. The most popular in this group are generics of Viagra, Levitra and Cialis.

And although the principle of action of these 3 drugs is quite similar, they have their own nuances: duration of action, dosages, contraindications, etc. To choose the best option for yourself, check out the features of each drug in our article, as well as a comparison of their characteristics.

Features of Levitra

Levitra is a type 5 phosphodiesterase inhibitor. Levitra is based on the vardenafil component, which stimulates the production of nitric oxide and inhibits PDE-5. Simply put, all these biochemical processes are aimed at relaxing the muscles of the penis and providing improved blood access to it.

How to apply

It is necessary to use Levitra 40-50 minutes before intimacy, 10 mg of the active substance at a time. For a day, you can use no more than 20 mg. The effect of one dose lasts approximately 4 hours.

Contraindications

Consider the cases in which the use of Levitra is contraindicated:

Intolerance to vardenafil or other components contained in the preparation;
Severe diseases of the heart and blood vessels;
Ulcerative diseases of the gastrointestinal tract;
Kidney or liver disease (renal or liver failure).

Side effects

As for the side effects of Levitra, they are quite rare and relatively harmless (unless, of course, we are talking about an overdose or taking the medicine in the presence of contraindications - in this case, the nervous or genitourinary system may fail).

Side effects that sometimes occur when taking Levitra include:

Pain in the temples;
Temporary digestive problems;
Nasal congestion;
The appearance of areas of inflammation in the mouth;
Feeling of nausea.

Before you know if a drug is right for you, you need to find out how it interacts with the drugs you are already taking (or have taken). When using Levitra, you should pay attention to the following nuances:

With simultaneous use with Erythromycin, you need to be careful: it increases the volume of vardenafil in the body by 2 times;
It is forbidden to take Levitra with Nicorandil;
With the simultaneous consumption of Levitra with Roinavir, it is necessary to reduce the amount of the first to 10 mg, since due to Rionavir, Levitra will be excreted from the body longer;
It is not recommended to use the drug with Ketoconazole, because. Ketoconazole increases the concentration of Levitra components by 4 times. In extreme cases, you must first consult a doctor;
It is also not recommended to use Levitra in conjunction with drugs used to suppress HIV infection.

It is not recommended to use Levitra along with alcoholic beverages, but it is not contraindicated either. The price of this drug is in the region of 300 rubles per 1 tablet.

Features of Cialis

The active ingredient in Cialis is Tadalafil. It inhibits cGMP and inhibits PDE-5, which allows the penis to stay in an erect state longer.

How to apply

Cialis should be taken 30-40 minutes before sex at a dosage of 20 mg. It is not recommended to take more than 1 dose of the drug per day. The drug works up to 36 hours.

Contraindications

One of the distinguishing features of Cialis is a short list of contraindications. In fact, it only includes an allergy or intolerance to one of the components of the drug. Cialis is also not recommended for persons under 18 years of age. Also, Cialis should not be taken by women.

There are some diseases in which Cialis is not recommended, but not prohibited. These are high blood pressure, diseases of the cardiovascular system, problems with the nervous system and the presence of degenerative diseases of the retina.

Hydroxides of aluminum and magnesium increase the time required for the absorption of Cialis;
Simultaneous administration of the drug with antihypertensive drugs can reduce the patient's pressure.

With the simultaneous use of Cialis and alcohol, no negative consequences should be observed (except for a slight decrease in the effectiveness of the drug). The price of Cialis is around 250 rubles per tablet.

Features of Viagra

Viagra appeared on the pharmacological market earlier than other PDE-5s. Its main component is Sildenafil citrate, which inhibits PDE-5 and stimulates the release of nitric oxide, which contributes to the stabilization of potency (a similar principle in Levitra).

You can’t mix Viagra with alcohol, and this is one of its main disadvantages, since intimacy often implies prior alcohol intake. The price of the 1st Viagra tablet is around 250 rubles.

What to choose: Viagra, Cialis or Levitra

So which is better: Viagra, Cialis or Levitra? It is important to understand that all 3 drugs have the same mechanism of interaction with the body, i.e. their effectiveness is quite comparable. All 3 drugs are the best in the business. However, there are nuances here.

Action speed

If we compare drugs by the speed of the onset of the effect, then Levitra wins: a man will feel the effect from him in half an hour. In turn, Viagra gives the same effect only after 1 hour.

Duration of action

The longest acting remedy is Cialis. It is able to provide the desired effect for 1.5 days, while Viagra and Levitra can boast only 5-6 hours.

Availability of funds for the elderly

Older people often need generics. And it is most important for them that the medicine causes as few side effects as possible. In this regard, Viagra is leading - it will not cause anything worse than mild nausea and headaches.

Failures in the intimate sphere significantly reduce the quality of a man's life and directly affect not only his psycho-emotional state, but also his relationship with his partner. Most often, men are concerned about erectile dysfunction. This violation is a consequence of insufficient filling of the penis with blood, and, accordingly, the inability to copulate. The modern pharmaceutical industry provides a wide range of drugs designed to help solve this delicate problem. There are so many such medicines that the question arises, which one should be preferred?

Collapse

The following medicines are very popular: Viagra, Levitra, Cialis. Experts say that among all the tablets, it is Levitra that has the greatest effectiveness at the lowest dose. But other means have significant advantages. Let's consider in detail each of them and compare: what is better than Viagra or Cialis or Levitra.

The most popular means to increase potency

The action of Levitra, like its analogues, is based on the suppression of the action of type 5 dosphodiesterase, an enzyme that affects the regulation of signaling pathways. The function of the drug as an FDA-5 inhibitor causes a high-quality and long-lasting erection.

It should be remembered that such medications will not bring the desired effect in the absence of sexual desire - they are effective only with sexual stimulation.

The choice of a passing agent is simple only at first glance. In fact, before making an appointment, the doctor must carefully study the history and take into account many indicators: the presence of chronic diseases, general health, and even the psychological state of the patient. Only the totality of all the necessary information about the patient is a sufficient basis for choosing one or another drug.

For the patient, the priority are such characteristics of medicines as:

the speed of the effect;
duration of action of the tablet;
the possibility of simultaneous administration of the drug with alcoholic beverages and food;
dosage and frequency of administration;
possible side effects on the body;
price.

As we already know, the effectiveness of the drug is based on the mechanism of suppression of a special enzyme - PDE-5. This effect is due to the presence of vardenafil in the composition, which is the main component of the drug. The price of the product varies from 800 to 1300 rubles.

The organs of the gastrointestinal tract quickly absorb the active substance of Levitra, causing the release of nitric oxide and the simultaneous suppression of PDE-5. This influence leads to the relaxation of smooth muscles and the active flow of blood to the penis. Tablets are recommended for use half an hour or an hour before the intended intimate relationship. The manufacturer indicates a dose for a single dose of 10 mg.

Like any medicine, Levitra has several contraindications. Among them:

diseases of the heart and circulatory system;
atherosclerosis;
peptic ulcer of the stomach and duodenum;
liver failure;
individual sensitivity to the components of the drug.

"Levitra" must be taken at least half an hour before sexual intercourse

The main advantage of Levitra is its low cost, but an impressive list of contraindications and undesirable effects can scare away. In fact, complications from taking pills are very rare and are mainly associated with exceeding the permitted dosage. The most common side effects are malfunctions of the nervous and circulatory systems, functional disorders of the liver and urinary system.

By the way, the drug can change the performance of tests during laboratory tests, namely, to increased activity coefficients of liver enzymes. This effect is due to the influence of vardenafil on hepatobiliary processes in the body.

Of all the means to improve the quality of potency, Viagra is the most popular. The reason for this prevalence is that the drug entered the pharmaceutical market a little earlier than its counterparts. Tablets can be bought without a prescription, and their cost exceeds 1400 rubles.

The high effectiveness of Viagra is due to the content of sildenafil. This is a substance that has the same PDE-5 inhibitory action as vardenafil. This component helps to relax the smooth muscles of the penis and provokes the supply of the latter with blood. Levitra and Viagra affect potency by the same mechanism, the drugs differ only in the main active ingredient. What is better Levitra or Viagra? First of all, you should pay attention to the cost, it is the main difference between the drugs.

The rate of absorption and achievement of the desired effect of the two drugs is almost the same, but Viagra is very poorly suited for simultaneous intake with alcohol. The standard recommended dosage of Viagra is 50 mg. Take it in advance - an hour or two before sexual intercourse. The action of the tablet lasts for 3-4 hours.

Take the pill one to two hours before sexual intercourse

Compared to Levitra or Cialis, Viagra is less likely than other drugs to provoke side effects and complications. This opinion is also confirmed by patients who took different drugs and could directly compare their effect. In this case, the answer to the question "Viagra or Cialis which is better" is almost unambiguous.

However, the tablets have some contraindications:

individual allergy to the components of the drug;
impaired functioning of the liver or kidneys;
heart attack, stroke in history;
pathologies of the cardiovascular system;
ulcer disease.

Of the undesirable effects, patients most often note allergies, disorders of the digestive tract, anemia, an increase or excessive decrease in pressure. Occasionally, there are violations of the functioning of the respiratory and excretory systems.

Tablets have certain contraindications, which must be read before taking

Please note: the simultaneous use of Viagra with nitrogen donors is prohibited.

This medicine is also in the top three among the most purchased drugs to increase potency. The desired effect of the pill is half an hour to an hour after ingestion. The action of the drug is based on the stimulation of the local release of nitric oxide and the inhibition of PDE-5. Thus, the principle of action is the same for Viagra, Cialis and Levitra.

The tablet is taken half an hour before sexual contact. The dose for a single dose is 20 mg. The drug has some contraindications:

Individual intolerance to tadalafil and other components.
Age up to 18 years.
Simultaneous use of alpha-1-blockers.
Degenerative changes in the structure of the retina.
Violations of the functioning of the hematopoietic and nervous systems.
Failures in the work of the heart.
Leukemia.
Anatomical deformities of the penis.

As for side effects, the use of Cialis can lead to such phenomena as:

muscle pain;
a rush of blood to the surface of the skin;
swelling of the eyelids;
allergy;
dyspepsia;
dizziness;
disorders of the central nervous system.

Before taking the drug, you should familiarize yourself with the list of contraindications and side effects.

Cialis, like other similar drugs, should not be taken with nitrites, nitrogen donators and nitrates.

Viagra, Cialis or Levitra which is better? This can be understood by comparing drugs. Although the three medicines work on the same principle, there are a number of functional features that directly affect the choice of remedy.

So, if the priority is the rapid onset of the effect, it is better to take a closer look at Levitra - of all means, it has the fastest result. The action of the tablet begins in a quarter of an hour. Cialis and Viagra cause the desired effect no earlier than half an hour.

If you need to lengthen sexual intercourse, you should pay attention to Cialis. The medicine is effective for as long as 36 hours, but the action of Viagra and Levitra will end after 4 and 8 hours, respectively. As for the means to increase potency in men over 60 years old, then at this age it is better to give preference to Viagra. According to statistics, it is these pills that cause side effects less often than others.

Levitra and Cialis are compatible with alcohol. And it is advisable to refuse Viagra, if the drug is incompatible with alcoholic beverages

If you need to choose a drug that is compatible with the intake of alcoholic beverages, then it is recommended to use Cialis or Levitra. Viagra mixed with alcohol has a strong toxic effect on the body. As you can see, each of the drugs has its own advantages, disadvantages and side effects. It is impossible to say unequivocally which tool is better. The selection of drug methods to improve potency depends on the desired effect, must be strictly individual and carried out according to the characteristics of a particular patient.

For various reasons, all of the above tablets may be contraindicated. In this situation, you can pay attention to active dietary supplements. They have 3 important benefits:

have a complex effect on the body;
have no contraindications;
do not have a toxic effect.

It is difficult enough to find effective dietary supplements, as many so-called "placebos" are being produced today. However, among such funds there are really effective potency stimulants.

There are quite a few analogues of drugs on the market.

Similar drugs to Levitra:

Impaza;
Viprogra;
Sealex;
Yarsagumba;
Gumisil;
Sayoma capsules;
Vuka Vuka.

The cost of Levitra analogues varies depending on the manufacturer. As a rule, homeopathic remedies and supplements cost significantly less than drugs whose action is based on the inhibition of phosphodiesterase-5. So, 20 Impaza tablets will cost about 400 rubles.

If a man suffers from a potency disorder, then, by and large, the choice of the drug is not so important. Any of these means leads to an improvement in the quality of intimate life. Medications to improve erection have a positive effect on relationships with a partner, gives a man confidence in his abilities.

Regardless of which generic you choose, you should know the following:

Before taking the tablets, you must carefully study the instructions. Approximately 10% of patients may experience side effects ranging from headache to stuffy nose and facial flushing.
It is strictly forbidden to combine the intake of different drugs or exceed the indicated dosages to enhance the effect.
Do not doubt the effectiveness of the drug, but remember that its possibilities are not unlimited. The pill will increase blood flow, thereby strengthening the erection, but will not increase libido.
Such medicines do not belong to the category of medical. The therapeutic effect can be maintained if the drug is taken in a course. In this case, you can try to reduce the dose of the drug over time.
It is best to use analogues when the general condition of the body is satisfactory. For a tired and sick man, the drug will not only not help, but can also harm.
During sexual contact, the body experiences sufficient dehydration, especially if a remedy was used to improve potency. After taking the tablets, it is recommended to drink enough clean water. Dehydration can lead to headaches and even cramps, so drinking regularly is important.
The dosage of a single dose is calculated for average weight indicators. If the weight is significantly higher or, conversely, lower than normal, it is better to calculate the individual dosage. To do this, you should consult a doctor.

In order not to decide which drug is better, you can use not only the information provided, but also seek the advice of a doctor. He will provide Cialis Viagra Levitra comparison and give a clear recommendation according to the specific situation.

Sexual satisfaction is a very important part of life for any person, and no problem is perceived as painful as failure in the intimate sphere. Especially when it comes to men, who often make their masculinity dependent on victories on the personal front. However, in our age of stress and increased stress, it is so difficult to maintain your health and please your beloved in bed.

In recent years, doctors are increasingly diagnosing erectile dysfunction to fairly young representatives of the strong half of humanity. And they immediately warn patients that these words are not a sentence at all. Indeed, there are numerous drugs on sale that can help to cope with an unpleasant problem and fully establish a normal sex life.

Usually the choice of men falls on Levitra or Cialis. What is better and what characteristics you need to focus on when buying such drugs, we will tell readers today.

Brief characteristics of drugs for erectile dysfunction

Pharmacies sell many drugs that promise men an incredible result and sensations after their use. Sometimes it is extremely difficult to choose among them, because even sexologists usually leave the choice to the patient, simply recommending certain means to them. In addition to the original drugs, drugs for erectile dysfunction are represented by a large number of generics Viagra, Levitra and Cialis. They are produced mainly by Indian pharmaceutical companies, which supply their goods at much lower prices than European brands. However, these drugs are almost identical in composition, which confuses most buyers who dream of finding the most effective and inexpensive remedy.

So, what is better - Levitra or Cialis? We will try to answer this question to readers in the article, but for now we will briefly characterize both drugs.

Experts believe that the mechanism of action of these drugs is similar. They strengthen the erection, allowing you to make sexual intercourse full and in many cases prolonging it. This happens due to the expansion of blood vessels and a rush of blood to the penis. Many patients write in reviews that when taking these drugs, they observed not only an improvement in the quality of intimate life, but also an increase in the size of the penis. Of course, not all men had a similar effect, but such cases are not so rare.

"Levitra" and "Cialis" are called PDE-5 inhibitors, which act only in case of sexual arousal. This fact must be taken into account when buying the drug. Without sexual stimulation and caresses of the woman you love, you will not get the desired effect.

Doctors, prescribing drugs for erectile dysfunction, usually focus on the age and psychological state of the patient. However, even experts cannot unambiguously determine which is better - Levitra or Cialis. Indeed, when buying a medicine, it is necessary to take into account many individual factors, which we will now discuss.

Criteria for choosing a drug

Patients cannot fully evaluate and analyze the composition of erectile dysfunction remedies, but they know exactly what they want for their money. Therefore, the criteria for choosing a medicine, which most men adhere to, may look like this:

speed of action;
duration of exposure;
admissibility of use with food and alcoholic beverages;
dosage of the drug;
reception frequency;
side effects;
the cost of the medicine.

To help patients decide, manufacturers began to produce drug test kits. They contain two or three tablets of the most popular drugs. The cost of such a set starts from eight hundred rubles, and it is in great demand. After all, this option allows you to practically choose the most suitable tool for yourself. But for those who do not want to risk their health, you should read our article and make a comparative analysis of tablets based on these characteristics.

Common features

Comparisons of "Levitra" and "Cialis" are carried out quite often, so it was easy to highlight the similarities of these drugs. They are listed below:

Action only in the presence of sexual arousal. We have already mentioned this fact, but we will repeat it anyway. Pills become effective only if there is a sexual partner.
Taking medications. Both drugs must be taken a few minutes before sexual intercourse.
Degradation of active substances. Liver enzymes contribute to the processing and breakdown of the components of Levitra and Cialis, so people suffering from liver diseases should not take these medicines.

It is worth mentioning that the drugs described by us have several similar contraindications. Usually a doctor talks about them, but still we could not help but list them:

problems with blood pressure;
parallel reception of "Erythromycin" and drugs of the same group;
violations of the structure of the penis.

I would also like to note that, despite the similarity, drugs have a number of differences. In addition, Levitra is a drug that appeared on the Russian market not so long ago, unlike Cialis. However, this did not prevent him from becoming a very popular remedy, which is currently being bought up much more actively than the famous Viagra.

Differences between drugs

Both drugs are used to increase potency, but they act on the body a little differently. And this is noticed by all men who have used samplers of drugs to combat erectile dysfunction.

The effect of Levitra is not only to increase erection, but also to suppress premature ejaculation. In this case, the desired result is achieved after the first dose and has a prolonged effect.

"Cialis", if you focus on the reviews of men, is designed for long-term use. Despite the fact that it gives results even with a single application, a noticeable effect will only be with regular use. It should be borne in mind that the drug begins to act approximately half an hour after ingestion. And the effect itself lasts for 36 hours.

"Levitra": instructions for use, price and reviews

Many men consider this product to be one of the best in their group. They are attracted by the rapid onset of the effect (as early as twenty minutes after ingestion). One tablet is enough for several sexual acts, because the action lasts at least ten hours.

With a single dose, the drug enhances erection, and regular use completely eliminates problems in the intimate sphere and increases the number of sexual acts. At the same time, Levitra is suitable for patients of any age.

Most often, this drug is prescribed in cases where erectile dysfunction is caused by the following reasons: stress, malnutrition, bad habits, and so on.

One tablet contains 20 milligrams of the active substance (vardenafil). The package usually contains ten tablets. Their cost fluctuates within one and a half thousand rubles.

The drug is perfectly combined with alcohol and food, it is better to take the pill approximately 30 minutes before sexual intercourse. Judging by the reviews, "Levitra" can be taken twice a week. It is also suitable for occasional use by healthy men. In this case, it prolongs sexual intercourse and enhances the sensations during it.

Side effects

Most men, when purchasing a drug, are primarily interested in reviews, price and instructions for use. "Levitra" also has a number of side effects, which you also need to know about before taking the pills.

Despite the fact that they are extremely rare, experts advise always focusing on them. The main side effects of "Levitra" can be considered headaches and dizziness. Sometimes they can manifest themselves in redness of the skin, increased blood pressure, nausea, and temporary visual impairment.

"Cialis": a description of the drug

Cialis for men has been sold in Russia for a long time. The active substance of the drug is tadalafil, which is loved by patients due to the minimum number of side effects and duration of exposure.

It is noteworthy that it goes well with any food and drink. This also impresses the consumer, because a man may not think before taking a pill what exactly he can eat.

It is worth noting that this drug has much fewer side effects than the previous one. However, it is Cialis that more often than its analogues causes stomach cramps.

On average, one tablet of the drug costs about three hundred rubles. In pharmacies, you can buy packages in which one, five and ten tablets are packaged. Each buyer chooses the required number of pills, given that they can be taken no more than twice a week.

Preparations for women

Among the generics of Viagra, Levitra and Cialis, you can also find drugs for women. Yes, yes, don't be surprised. Sometimes ladies also need drugs that will help them to relax, enhance sensations and achieve orgasm. Women's Cialis is made in India and contains the same tadalafil as in tablets intended for men. However, here its dosage is reduced to ten milligrams.

It relaxes smooth muscles and promotes blood flow to the pelvic organs. This affects the sensations during intercourse.

Contraindications

Female "Cialis" has a number of contraindications. First of all, these include pregnancy and circulatory problems. Also, do not combine taking pills with alcohol, in this case it is contraindicated. The list of contraindications includes oncological diseases.

There are cases when patients have intolerance to the active substance Cialis. This also serves as an obstacle to taking the drug.

A few words about generics

The drugs we describe have a large number of generics that are sold in all pharmacies without a doctor's prescription. For example, patients often replace Cialis with Indian-made analogues, such as Erectafil, Tadadel, Tadaga and others.

Judging by their effectiveness, we can say that they are no worse than the original, but the cost of tablets is two or even four times less than the branded drug. Therefore, many men switch to generic drugs in order not to overpay for the brand name.

What to choose: draw conclusions

Which is better - Levitra or Cialis? It is impossible to answer this question unequivocally, because men themselves make a choice, focusing on their own preferences and capabilities. But experts can advise to be determined with the drug only on the basis of the goals.

If you need to be in shape for a long time, then choose Cialis and its analogues. And in the case when you plan to take pills for a long time, it is better to buy Levitra.

At the moment, for the treatment of potency disorders, there are a large number of funds. However, phosphodiesterase type 5 inhibitors (PDE5) are still in the greatest demand - drugs that are similar in principle to Viagra. The most popular in this segment are Cialis and Levitra. Each of these medications has its own advantages and disadvantages, assessing which you can make the right choice.

The mechanism of action of drugs

Normally, an erection occurs due to increased blood filling of the cavernous bodies of the penis during sexual arousal. This is a consequence of the release of nitric oxide, which activates the enzyme guanylate cyclase, which leads to an increase in the level of cyclic guanosine monophosphate (cGMP) in the cavernous bodies, starting a cascade of biochemical reactions and relaxing the smooth muscles of the vessels of the penis (as a result of this, its filling with blood increases).

The mechanism of work of Cialis and Levitra is to inhibit the work of the phosphodiesterase type 5 enzyme, which destroys cGMP. As a result, the duration of action of endogenous nitric oxide increases.

Cialis

The active ingredient of the drug is tadalafil. Tablets are available in two dosages: 5 and 20 mg.

Do not confuse Cialis with Sealex, which is herbal and has a different mechanism of action.

Cialis at a dosage of 5 mg is used for daily intake in men with high sexual activity (2 or more sexual contacts per week). The drug should be taken at the same time, regardless of meals, 1 tablet. With unsatisfactory tolerability of tadalafil, the dosage can be reduced to 2.5 mg per day.

Cialis at a dosage of 20 mg is indicated for men who have rare sexual intercourse (less than 2 times a week). In this case, the drug is taken immediately before intimacy against the background of sexual arousal. The effect occurs within 16 minutes. With a single dose of the drug at a dosage of 20 mg, the duration of action is up to 36 hours.

Contraindications:

age less than 18 years;
joint intake with drugs containing an NO-group (nitrate) in the chemical formula, since the risk of developing severe arterial hypotension increases.

Adverse reactions:

dyspeptic syndrome (nausea, abdominal pain, diarrhea or constipation);
back pain;
dizziness, headache;
eye irritation (soreness, swelling of the eyelids, redness).

In unstable angina or angina pectoris of a significant functional class (3-4), myocardial infarction during the last 3 months, the patient should avoid sexual activity, despite the fact that the drug is not contraindicated for use.

If the erection lasts more than 4 hours, you should immediately consult a doctor.

Levitra

The active ingredient in Levitra is vardenafil. The drug is available in tablets containing 5, 10 and 20 mg of vardenafil.

The drug should be taken orally, not coordinating with meals, no later than 25 minutes before the planned sexual intercourse. Levitra is used against the background of sexual arousal. The effect lasts up to 4-5 hours. Do not take Levitra more than once a day. In men without pathology of the liver and kidneys, the initial dose is 10 mg. With an unsatisfactory effect, it is increased to 20 mg per day.

In severe renal and hepatic insufficiency, it is recommended to start dose titration from 5 mg. In the future, the dose increases depending on the tolerability of the drug.

Contraindications:

individual hypersensitivity to the components of the drug;
age less than 18 years;
joint use with drugs containing an NO-group (nitrate) in the chemical formula, since the risk of developing severe arterial hypotension increases;
combination with antiretroviral therapy with HIV protease inhibitors.

Adverse reactions:

anxiety, fainting, drowsiness, dizziness, headache;
sensation of hot flashes, fever, increase / decrease in blood pressure, orthostatic hypotension, angina pectoris pain;
nausea, dyspepsia, increased liver enzymes;
swelling of the mucous membrane of the nasal passages, rhinorrhea, shortness of breath, swelling of the larynx, nosebleeds;
increased lacrimation, intraocular pressure, blurred vision;
allergic reactions;
priapism;
back pain and muscle pain;
increased sensitivity of the skin to ultraviolet radiation.

If the erection lasts more than 4 hours, you should immediately consult a doctor.

Comparison of drugs

Both drugs should be used with caution in the following features of the body:

anatomical deformities of the penis (Peyronie's disease, etc.);
tendency to priapism (prolonged, painful erection);
congenital prolongation of the QT interval on the electrocardiogram;
stenosis of the aortic mouth;
tendency to bleed;
retinopathy;
exacerbation of peptic ulcer;
significant renal (CKD 4-5) and liver failure.

According to the mechanism of action, the drugs belong to the same group, but they have a number of differences. For clarity, a comparison of Cialis and Levitra is presented in the table.

For erectile dysfunction, phosphodiesterase inhibitors are most commonly used. They help stabilize potency by stimulating a more active flow of blood into the penis area. The best drugs in this group are Viagra, Levitra and Cialis.

Which of these medicines should you use? It is impossible to answer this question unambiguously. Each of the drugs has a number of its pharmacological features. But the principle of action of medicines is identical.

Levitra, Viagra and Cialis differ in duration of action, composition and method of administration. There are also significant differences in dosages.

Features of Levitra

Which is better - Viagra, Cialis or Levitra? To understand this issue, you should consider each drug separately. So, Levitra is a type 5 phosphodiesterase inhibitor. The active ingredient of the drug is vardenafil. The cost of tablets is 800-1300 rubles.

The active ingredient is rapidly absorbed in the digestive tract. Vardenafil stimulates the release of nitric oxide. In this case, the substance inhibits PDE-5. Due to this, the smooth muscles of the penis relax, and the blood begins to flow more actively to the penis.

Tablets should be taken 30-60 minutes before sexual intercourse. According to the instructions, a single dose is 10 mg. Among the contraindications to the use of the drug are:

Hypersensitivity to vardenafil and auxiliary components.
Atherosclerosis.
Diseases of the cardiovascular system.
Ulcerative lesions of the digestive tract.
liver failure.
Malfunctions of the kidneys.

As you can see, the list of contraindications for Levitra is quite impressive. The advantage of the drug over competitors is the relatively low price.

Unfortunately, Levitra has a lot of side effects. However, in practice, complications are extremely rare. Only with prolonged use or overdose, violations of the central nervous system, hematopoietic, hepatobiliary and urinary systems are possible.

By the way, Levitra can affect laboratory parameters. There are cases when the use of tablets led to an increase in the level of activity of liver enzymes.

Viagra for impotence
