Clinical data
In a placebo-controlled cross-examination of patients with proven early age macular degeneration (n=9), Sildenafil Vega Extra 120 was well tolerated at a single dose of 100 mg. There were no clinically significant changes in vision evaluated by special visual tests (visual acuity, Amsler lattice, color perception, color simulation, Humphrey perimeter and photostress).
Efficiency. The efficacy and safety of Sildenafil Vega Extra 120 were evaluated in 21 randomized double-blind placebo-controlled studies lasting up to 6 months in 3000 patients from 19 to 87 years with erectile dysfunction of different etiology (organic, psychogenic or mixed). The efficacy of the drug was evaluated globally using an erection diary, an international erectile function index (validated questionnaire on the state of sexual function) and a partner survey.
The effectiveness of Vega Extra 120 Mg, defined as the ability to achieve and maintain an erection sufficient for satisfactory sexual intercourse, has been demonstrated in all studies and confirmed in long-term studies lasting 1 year. In studies with the use of fixed-dose proportion of patients reporting that treatment improved their erections were 62% (dose of Sildenafil Vega Extra 120 25 mg), 74% (dose Sildenafil Vega Extra 120 50 mg) and 82% (dose Cobra 120 Vega Extra 100 mg) compared to 25% in the placebo group. Analysis of the international index of erectile function showed that in addition to improving erection treatment Sildenafil Tablets Vegah Extra Cobra also increased the quality of orgasm, allowing to achieve satisfaction from sexual intercourse and overall satisfaction.
According to the generalized data, 59% of patients with diabetes, 43% of patients who underwent radical prostatectomy and 83% of patients with spinal cord injuries (against 16, 15 and 12% in the placebo group, respectively) were reported to have improved erection in the treatment of Vega Extra Cobra 120.
Pharmacokinetics
Cardiovascular complications
During the post-marketing use of Cobra Vega Extra Strong 120 Mg for the treatment of erectile dysfunction, adverse events such as severe cardiovascular complications (including myocardial infarction, unstable angina, sudden cardiac death, ventricular arrhythmia, hemorrhagic stroke, transient ischemic attack, hypertension and hypotension) were reported, which had a temporary connection with the use of Sildenafil Vega Extra 120. Most of these patients, but not all of them, had risk factors for cardiovascular complications. Many of these adverse events were observed shortly after sexual activity, and some were observed after taking Cobra Vega 120 without subsequent sexual activity. It is not possible to establish a direct link between the reported adverse events and those or other factors.
Hypotension
Cobra Vega 120 Mg has a systemic vasodilating effect, leading to a transient decrease in blood PRESSURE, which is not clinically significant and does not lead to any consequences in most patients. However, before prescribing Sildenafil Vega Extra 120, the doctor should carefully assess the risk of possible undesirable manifestations of vasodilating action in patients with relevant diseases, especially against the background of sexual activity. Increased susceptibility to vasodilators is observed in patients with obstruction of the output tract of the left ventricle (aortic stenosis, GOCMP), as well as with the rare syndrome of multiple systemic atrophy, manifested by a severe violation of the regulation of blood PRESSURE from the autonomic nervous system.
Since the combined use of Extra Vega and α-blockers can lead to symptomatic hypotension in some sensitive patients, Vega Extra 120 should be used with caution in patients taking α-blockers (see "Interaction"). To minimize the risk of postural hypotension in patients taking α-blockers, the drug Vegah Cobra should be started only after achieving stabilization of hemodynamic parameters in these patients. It should also consider reducing the initial dose of Sildenafil Vega Extra 120 (see. "Dosage and administration"). The doctor should inform patients about what actions should be taken in case of symptoms of postural hypotension.
Visual impairment
In rare cases, during post-approval use of all of the inhibitors of PDE5, including Sildenafil Vega Extra 120, 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 Vegah Extra 120 Indication 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 120 Mg, 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 Sildenafil Vega Extra 130 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 Sildenafil Vega Extra 120 in patients with retinitis pigmentosa absent, so these patients should not be used Sildenafil Vega Extra 120 (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 120. 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 Cobra Vega 120, consult a doctor immediately.
Bleedings
Vega Extra 120 Mg enhances the antiplatelet effect of sodium nitroprusside, a nitric oxide donator, on human platelets in vitro. Data on the safety of Sildenafil Vega Extra 120 in patients with a tendency to bleeding or exacerbation of gastric ulcer and duodenal ulcer are not available, so the drug Sildenafil Vega Extra 130 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 (Sildenafil Vega Extra 120 — 12.9%, placebo — 0%) than in patients with primary pulmonary arterial hypertension (Vega Cobra 120 Mg — 3%, placebo — 2.4%). Patients receiving Vega Extra Cobra 120 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 Cobra 120 Vega Extra together with other PDE-5 inhibitors or other drugs for the treatment of pulmonary hypertension containing Cobra Vega Extra Strong 120 Mg (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 Cobra 120 Mg any negative effect on the ability to drive a car or other means was not observed. However, since when taking Sildenafil 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.
