What is Viagra?
The drug, patented by an American company, Viagra Pfizer, is a treatment for impotence. Interestingly, the effect on sexual function was a side effect, due to which the drug gained such popularity. Initially, the drug was developed for the treatment of cardiovascular pathologies, in particular, coronary heart disease and angina pectoris.
ü Interesting! Viagra is one of the most recognizable tablets in the world, due to its specific diamond shape and blue color.
The effect of the drug is based on the stimulation of blood flow to the genitals. There is a myth that the drug is effective not only for men, but also for women, however, clinical trials have not been conducted.
The mechanism of action on men
The drug relaxes the smooth muscles of the cavernous bodies of the penis and dilates blood vessels, contributing to their better filling with blood. The result is a strong erection for several hours.
Despite the apparent simplicity of action, the drug has one significant nuance - to achieve a strong erection, sexual arousal is necessary, which, as you know, occurs in the head, but not in the genitals.Thus, a drug effective in the treatment of severe forms of erectile dysfunction is completely useless in case of psychological impotence due to the lack of sexual desire against the background of complexes, internal conflicts or psychological barriers.
On average, a medicine begins to act 40-120 minutes after ingestion.
The exact time of occurrence of the therapeutic effect depends on several factors:
- eating;
- the age of the man;
- general health.
In elderly patients with renal or hepatic insufficiency, the effect of this drug is often delayed by about 1-1.5 hours, so the “blue pill” begins to act after 2-3 hours. The result is stored for 4-5 hours. Excessively fatty foods or simultaneous use with alcohol can reduce the duration of action.
The composition of the drug
The active substance is a PDE5 inhibitor sildenafil. Viagra tablets for men are available in different dosages - from 25 to 100 mg. Recently, a large number of cheap generics have appeared, which often contain increased dosages of the active substance - up to 150 mg.
The original preparation additionally contains cellulose, lactose, calcium, magnesium stearate and a number of dyes and preservatives that are not harmful to health. Tablets are available in cardboard packaging with the company logo of the manufacturer. The most popular product design is one tablet per pack. However, pharmacies also have species with 2, 4, and 12 pills.
Recently, another type of release of the original drug has appeared - tablets dispersible in the oral cavity. They have a pleasant taste and do not require swallowing. This form is perfect for men with gastrointestinal diseases, since the active substance in this case is absorbed by the mucous membrane of the oral cavity and penetrates the blood, bypassing the gastrointestinal tract.
In what cases is used
Indication for the use of the drug is only one - it is erectile dysfunction or impotence. However, the medication is effective only in the presence of sexual arousal, therefore, it is prescribed for the treatment of vascular impotence, as well as dysfunction against the background of diseases of the prostate gland (prostatitis, benign hyperplasia).
It should be noted that the “blue pill” does not treat erectile dysfunction, but only eliminates it for a while. After removing the active substance from the body, the problem of impotence remains. However, Viagra allows many men with severe erectile dysfunction to feel healthy again, and therefore enjoys well-deserved popularity.
Instructions for use and dosage
A medication for the treatment of erectile dysfunction is indicated to be taken 2-3 hours after a meal. The recommended dosage for this is 50 mg. With low efficiency, an increase to 100 mg is acceptable in the next dose, if there are no contraindications and the substance is well tolerated by a man. If 50 mg is enough to quickly achieve an erection, with a subsequent dose, you can reduce the dosage. Also, Viagra 25 mg is recommended for first use in older men with impaired liver and kidney function. This allows you to assess the tolerability of the drug for the next correction of the dosage regimen by a doctor.
The maximum allowable daily dosage is 100 mg of the drug. You can take a “one night pill” no more than once a day.
In general, the instructions for use do not contain strict restrictions on the duration of administration. If the patient tolerates the drug well and does not have side effects, you can take the tablets for a long time, but not more than once every 24 hours. The only exceptions are persons with diseases in which sex is not recommended (severe cardiac pathologies, hypertensive crises, pathologies of the genital organs).
Drug interaction
Sildenafil is fairly rapidly absorbed and does not react with other drugs, but in some cases negative drug interactions are possible.
- If a man has been using the ketoconazole antifungal agent in tablets for a long time, it is necessary to consider the possibility of taking the minimum dosage for potency, since an antimycotic can theoretically increase the risk of side effects. The same applies to the combination of sildenafil with erythromycin and cimetidine.
- Ritonavir increases the half-life of the drug for the treatment of erectile dysfunction, which can lead to severe side effects, therefore, concomitant use is not recommended. And it is also forbidden to take a “blue pill” with nitrates due to the threat of a sharp decrease in blood pressure.
- For patients with prostatitis and adenoma who take alpha-blockers (Omnic and analogues), it is advisable to consult a doctor before taking Viagra, since there is a risk of increased side effects of drugs for the treatment of urination disorders. This combination of drugs can provoke orthostatic hypotension.
While taking the "one night pill", you should refuse to use grapefruit juice and fatty foods, since such products can slow down the effect of the substance.
Alcohol compatibility
Alcohol also reduces the effectiveness of potency remedies. Studies have shown that drinking alcohol can delay the onset of an erection by 3 hours. At the same time, alcohol accelerates the excretion of sildenafil from the body, and therefore the effect of the drug is very reduced. Thus, to get the maximum effect and a strong erection, you will have to give up strong drinks.
Contraindications, side effects and overdose
The tool for rapid stimulation of potency has a number of side effects and contraindications, and is generally unsafe. Take medicine only as directed by your doctor. In addition, in order to purchase the presented drug, you must provide a prescription certified in the prescribed manner by the attending physician.
Contraindications:
- intolerance to the active substance or other components of the composition;
- conditions in which sexual abstinence is indicated;
- unstable angina pectoris and acute heart failure;
- optic neuropathy, leading to loss of vision;
- severe violations of the liver;
- degenerative lesion of the retina;
- acute cerebrovascular accident;
- recent myocardial infarction.
In case of impaired renal function, medication can be taken, but it is recommended to start with the minimum therapeutic dose and constantly evaluate overall well-being. With normal tolerance over time, the dose may be increased to 50 mg.
Tablets reduce blood pressure, therefore, it is not recommended for men with arterial hypotension (pressure below 80 to 50 mmHg).
The most common side effects that occur the day after taking the pill are flushing, migraine, dizziness, and nausea. Against the background of the use of large doses of Viagra, the development of visual impairment and color perception is possible. Quite often, patients complain of confusion and a breakdown that can be associated with a decrease in blood pressure.
And also among the reported side effects are indicated tachycardia, dyspepsia, edema of the lower extremities and allergic reactions. If severe side effects occur, seek medical attention.
The exact symptoms of an overdose are unknown. Repeated excess of standard amounts of medication leads to increased side effects. In this case, symptomatic therapy is needed.
Analogs of Viagra
Viagra - pills for men, which can be purchased at any pharmacy.In the wake of the drug’s high popularity, many analogues and generics with a lower cost have appeared. The most popular analogues are Dynamo, Vizarsin, Maksigra. Those who wish to save money, you can pay attention to the domestic drug Sildenafil-SZ, but it often causes side effects, compared with the original medicine.
It is strongly recommended not to purchase informal generics, the cost of which is 5-7 times lower than the original tablets, from dubious distributors. In the best case, a man will encounter a dummy, in the worst, he will receive a low-quality remedy that will cause serious complications.
If the composition of the drug Viagra is not suitable for a man because of an allergy or for other reasons, you can consult a specialist about taking Cialis or Levitra medicines. These are synonyms of Viagra with other active ingredients in the composition.
Before you buy a medicine, you need to remember that Viagra is intended to treat problems with erection, but not for prevention. Taking the remedy is not indicated for healthy men - there will be no effect from the pill, but adverse reactions will certainly occur.
