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 Signature Cobra Vega. 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 Sildenafil Vega Extra 130 Mg, consult a doctor immediately.
Bleedings
Sildenafil Vega Extra 120 enhances the antiplatelet effect of sodium nitroprusside, a nitric oxide donator, on human platelets in vitro. Data on the safety of Extra Vega in patients with a tendency to bleeding or exacerbation of gastric ulcer and duodenal ulcer are not available, so the drug Sildenafil 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 Cobra — 12.9%, placebo — 0%) than in patients with primary pulmonary arterial hypertension (Sildenafil Vega Extra 130 Mg — 3%, placebo — 2.4%). Patients receiving Sildenafil Vega Extra 130 Mg 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 Pills together with other PDE-5 inhibitors or other drugs for the treatment of pulmonary hypertension containing Vega Extra Cobra 120 (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 Sildenafil Vega Extra 130 Mg any negative effect on the ability to drive a car or other means was not observed. However, since when taking Sildenafil Vega Extra 130 Mg 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.
Sildenafil Vega Extra 130 Mg is a weak inhibitor of cytochrome P450 — 1A2, 2C9, 2C19, 2D6, 2E1 and 3A4 ISOENZYMES (IC50 >150 µmol). When taking Vega Extra Strong 120 in recommended doses, its Cmax is about 1 µmol, so it is unlikely that Sildenafil Vega Extra 130 Mg can affect the clearance of the substrates of these isoenzymes.
Signature Cobra Vega increases the hypotensive effect of nitrates both with long-term use of the latter, and with their appointment for urgent indications. In this regard, the use of Sildenafil Vega Extra 130 Mg in combination with nitrates or nitric oxide donators is contraindicated. While taking α-adrenoblocker doxazosin (4 and 8 mg) and Sildenafil Vega Extra 130 Mg (25, 50 and 100 mg) in patients with benign prostate hyperplasia with stable hemodynamics, the average additional decrease in sad/dad in the supine position was 7/7, 9/5 and 8/4 mm Hg.article, respectively, while in the standing position — 6/6, 11/4 mmHg, and 4/5.art. respectively. Reported rare cases of symptomatic postural hypotension in such patients, manifested in the form of dizziness (without fainting). In some sensitive patients receiving α-blockers, simultaneous use of Cobra 120 Vega Extra can lead to symptomatic hypotension.
There were no signs of significant interaction with tolbutamide (250 mg) or warfarin (40 mg), which are metabolized by CYP2C9 isoenzyme.
Signature Cobra Vega (100 mg) has no effect on the pharmacokinetics of the HIV protease inhibitor, saquinavir, which is a substrate of CYP3A4 isoenzyme, at its constant level in the blood.
The simultaneous use of Vegah Extra 120 Mg at equilibrium (80 mg 3 times a day) leads to an increase in the AUC and Cmax of bosentan (125 mg 2 times a day) by 49.8 and 42%, respectively.
Vegah Extra 130 (50 mg) does not cause an additional increase in bleeding time when taking acetylsalicylic acid (150 mg).
Vegah Extra 130 (50 mg) does not increase the hypotensive effect of alcohol in healthy volunteers with Cmax of alcohol in the blood on average 0.08‰ (80 mg/DL).
In patients with hypertension, no signs of interaction of Vega Extra Cobra 130 Mg (100 mg) with amlodipine were found. The average additional reduction in blood PRESSURE in the supine position is 8 mm Hg.V. (systolic) and 7 mm Hg.V. (diastolic).
The use of Sildenafil Vega Extra 130 Mg in combination with antihypertensive agents does not lead to additional side effects.
