Visual impairment

In rare cases, during post-approval use of all of the inhibitors of PDE5, including Vega Extra 120 Mg, reported NESN is a rare disease and the cause of the decrease or loss of vision. Most of these patients had risk factors, such as decreased ratios of excavation diameter to optic disc (stagnant disc), age over 50, diabetes, hypertension, CHD, hyperlipidemia, and Smoking. In an observational study evaluated whether recent use of drugs class of inhibitors PDE-5 with an acute onset NESN. The results indicate approximately a 2-fold increase in risk NESN within 5T1/2 after application of the PDE-5 inhibitor. According to published literature, the annual incidence of npins IS 2.5–11.8 cases per 100,000 men aged ≥50 years in the General population. Patients should be advised to stop Cobra Vega 120 therapy in case of sudden loss of vision and consult a doctor immediately.

Persons who have already had a case NESN have an increased risk of relapse NESN. Therefore, the doctor should discuss this risk with such patients, as well as the potential chance of adverse effects of PDE-5 inhibitors. PDE-5 inhibitors, including Vega Extra 120, in such patients should be used with caution and only in situations where the expected benefit outweighs the risk. In patients with episodes of development PINZN with loss of vision in one eye receiving Cobra Vega Extra Strong 120 Mg is contraindicated (see "Contraindications").

A small number of patients with hereditary retinitis pigmentosa have genetically determined disorders of the PDE of the retina. Information about the safety of the drug Vega Extra 120 in patients with retinitis pigmentosa absent, so these patients should not be used Sildenafil Vega Extra 130 Mg Cobra (see "Contraindications").

Hearing impairment

Some post-marketing and clinical studies have reported cases of sudden hearing loss or impairment associated with the use of all PDE-5 inhibitors, including Sildenafil Vega Extra 130 Mg Cobra. Most of these patients had risk factors for sudden impairment or hearing loss. There is no causal relationship between the use of PDE-5 inhibitors and sudden hearing impairment or hearing loss. In case of sudden hearing impairment or hearing loss while taking Vega Extra 120, consult a doctor immediately.

Bleedings

Vega Extra 120 enhances the antiplatelet effect of sodium nitroprusside, a nitric oxide donator, on human platelets in vitro. Data on the safety of Vega Extra 120 Mg in patients with a tendency to bleeding or exacerbation of gastric ulcer and duodenal ulcer are not available, so the drug Vega Extra 120 in these patients should be used with caution (see With caution).

The incidence of nosebleeds in patients with pulmonary hypertension associated with diffuse connective tissue diseases was higher (Vega Extra 120 — 12.9%, placebo — 0%) than in patients with primary pulmonary arterial hypertension (Cobra 120 Vega Extra — 3%, placebo — 2.4%). Patients receiving Vegal Extra in combination with an antagonist of vitamin K, the frequency of nasal bleeding was higher (8.8 percent) than patients who were not taking an antagonist of vitamin K (1.7 percent).

Use in conjunction with other means for the treatment of erectile dysfunction

The safety and efficacy of Vega Extra 120 together with other PDE-5 inhibitors or other drugs for the treatment of pulmonary hypertension containing Sildenafil Vega Extra 130 Mg Cobra (eg, Revatsio®), or other means for the treatment of erection disorders have not been studied, so the use of such combinations is not recommended (see "Contraindications").

Influence on the ability to drive and mechanisms. In patients receiving Vega Extra 120 any negative effect on the ability to drive a car or other means was not observed. However, since when taking Vega Extra 120 may develop dizziness, lowering blood PRESSURE, the development of chromatopsia, blurred vision, etc. side effects, care should be taken when driving and doing other potentially dangerous activities that require increased concentration and speed of psychomotor reactions. Also, you should be careful about the individual action of the drug in these situations, especially at the beginning of treatment and when changing the dosage regimen.

Vega Extra 120 is a potent selective inhibitor of cGMP-specific PDE-5.

Mechanism of action

The implementation of the physiological mechanism of erection is associated with the release of nitric oxide (NO) in the cavernous body during sexual stimulation. This, in turn, leads to an increase in the level of cGMP, the subsequent relaxation of smooth muscle tissue of the cavernous body and an increase in blood flow.

Vegab Extra does not have a direct relaxing effect on the isolated cavernous human body, but enhances the effect of nitric oxide by inhibiting PDE-5, which is responsible for the disintegration of cGMP.

Selective Vega Extra 120 against PDE5 in vitro, its activity against PDE5 superior activity against other known PDE isoenzymes: PDE-6 — 10 times; PDE-1 more than 80 times; PDE-2, PDE-4, PDE-7 PDE–11 more than 700 times. Vega Extra 120 is 4000 times more selective for PDE-5 than PDE-3, which is crucial because PDE-3 is one of the key enzymes in the regulation of myocardial contractility.

A prerequisite for the effectiveness of Vega Extra is sexual stimulation.

Sildenafil Vega Extra 130 Mg restores impaired erectile function in conditions of sexual stimulation by increasing blood flow to the cavernous bodies of the penis.
