Viagra: a detailed guide to the drug that improves potency

For Viagra has long been firmly established the glory of this panacea to combat the problems of the male genitalia. Argued that it is enough to take one pill, and the man will become a real “thunderstorm.” In fact, not so simple. The medicine is not a panacea, but the pharmaceutical agent cannot be blamed for inefficiency. The truth, as always, is somewhere in the middle.

The described drug is a synthetic stimulator of the guanylate cyclase substance, which is responsible for the normal erectile function. The drug is quite effective against some forms of erectile dysfunction, but it is categorically inappropriate for others. Since the action of the drug is not selective, but generalized, there is a high risk of side effects from the cardiovascular, digestive and other systems.

Is it worth taking Viagra, and when? In addition, there are other drugs against impotence and erection problems (for example, Cialis and others). When are they more effective? In these issues to be addressed.

WHAT IS THE COMPOSITION OF THE DRUG?

The main active ingredient of the drug is Sildanefil. Sildanefil is a synthetic substance, originally developed to normalize the work of the cardiovascular system. An effective effect on potency was discovered by chance as a result of clinical trials. In addition to the main active component in the structure of the drug are detected: magnesium stearate, calcium phosphate and other substances. They do not have pharmaceutical efficacy and are intended to give the drug a tabletted, solid texture (used as fillers).

WHAT FORM OF VIAGRA IS AVAILABLE?

HOW DOES THE DRUG WORK AND WHEN IS IT KNOWN TO BE INEFFECTIVE? Viagra is available in the form of diamond tablets, convex on both sides. The concentration of the main active substance varies from format to format and is 25, 50 and 100 mg per tablet. The dosage is selected based on the severity of erectile dysfunction and the nature of the violation of potency. Independently choose the dose can not be, this is a direct path to health problems. Packages contain from 1 to 12 tablets. The cost varies according to the quantity.

The drug is aimed at improving the blood supply to the penis (cavernous bodies). Normalizing blood circulation in the genital area, Viagra provokes a rapid onset of erection, and retention of persistent potency for several tens of minutes to an hour or even more. However, Viagra is far from a panacea.

It is not suitable in a number of cases:

  • Low libido. First of all, the drug is ineffective with reduced sexual desire. Libido is an indispensable attribute of normal potency. If sexual desire is absent, Viagra will be ineffective. Viewing pornographic materials is not enough, no mistake. As a rule, it is most often a question of physiological decrease in libido as a result of testosterone deficiency, intake of certain categories of drugs (neuroleptics, antidepressants, etc.).
  • Lack of sex hormones. Another important factor is the presence of normal hormonal levels. If the level of androgens, in particular testosterone, is insufficient, Viagra will be an ineffective drug. Blood supply to the penis will be optimal, but the erection does not occur.
  • Normal blood circulation in the genitals. The drug is not effective for use in people who do not have problems with blood supply to the penis. If they try it just for the sake of an interesting experience, it will not produce any additional effect. Everything else – legends and conjectures.
  • Vascular pathology of the penis. If there are vascular diseases of the penis, there will be no sense of Viagra. The pharmaceutical product itself is not a cure. It only increases blood flow. But if the vessels have lost elasticity and are not able to expand – for obvious reasons, there will be no effect.
  • Atherosclerosis of the vessels of the penis. Another factor is the inefficiency of the drug. Especially if there is occlusion of the lumen of the veins and arteries with cholesterol plaques. The problem is most often seen in obese patients, smokers, people who abuse alcohol and fatty, fried, salty foods.
  • Other violations of the patency of the blood supply structures.
  • Prostatitis. Prostatitis entails a violation of innervation, because Viagra, affecting only the blood circulation, is not effective.
  • Psychogenic erectile dysfunction. If the patient has psychogenic erectile dysfunction , Viagra will not help. This is a completely different problem, it does not have a purely physiological nature. It’s about psychosomatics.
Thus, Viagra is able to help only with minor circulatory disorders in the pelvic area. To effect came, you need to have, paradoxically, a healthy body.

MECHANISM OF ACTION

After taking the medication, it is rapidly absorbed into the bloodstream. The mechanism of erectile function is associated with an increase in the concentration of nitric oxide in the cavernous body of the penis. This substance stimulates the production of guanylate cyclase, a special enzyme. The substance presented is intermediate, it itself stimulates the activation of the cGMP substance.

The muscles of the penis relaxes, its tone is reduced, there is increased circulation in the genital area. As the manufacturer himself points out, in order for the drug to begin to function normally, it is required that the man experience high-quality sexual arousal. Otherwise, the action will not come. The maximum concentration of the drug in the bloodstream is reached after half an hour or two hours.

The drug is metabolized in the liver structures, the period of removal of safe metabolites is approximately 3-5 hours from the time of admission. Most of the metabolites excreted in the feces (about 85%), the rest is transported by the kidneys. Drug processing products are inactive.

IN WHAT CASES THE USE OF THE DRUG IS ALLOWED AND RECOMMENDED?

According to the instructions for use, the medicine is used for the complex treatment of erectile problems, which is of a vascular nature. In all other cases, the drug does not work. To normalize sexual function, firstly, stimulation of the sexual organ is required, and secondly, the use of other drugs. As part of monotherapy, medication is rarely used.
