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 Cobra Vega Extra Strong 120mg. 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 Extra Strong 120mg, consult a doctor immediately.

Bleedings

Cobra Vega Extra Strong 120mg enhances the antiplatelet effect of sodium nitroprusside, a nitric oxide donator, on human platelets in vitro. Data on the safety of Cobra Vega Extra Strong 120mg in patients with a tendency to bleeding or exacerbation of gastric ulcer and duodenal ulcer are not available, so the drug Cobra Vega Extra 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 (Cobra Vega Extra — 12.9%, placebo — 0%) than in patients with primary pulmonary arterial hypertension (Cobra Vega Extra Strong 120mg — 3%, placebo — 2.4%). Patients receiving Cobra Vega Extra Strong 120mg 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 Vega Extra Strong 120mg together with other PDE-5 inhibitors or other drugs for the treatment of pulmonary hypertension containing Vegah Extra 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 Cobra Vega Extra Strong 120mg any negative effect on the ability to drive a car or other means was not observed. However, since when taking Cobra Vega Extra Strong 120mg 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.

Influence of Sildenafil Vega Extra 120 on other drugs

Cobra Vega Extra Strong 120mg is a weak inhibitor of cytochrome P450 — 1A2, 2C9, 2C19, 2D6, 2E1 and 3A4 ISOENZYMES (IC50 >150 µmol). When taking Cobra Vega Extra Strong 120mg in recommended doses, its Cmax is about 1 µmol, so it is unlikely that Cobra Vega Extra Strong 120mg can affect the clearance of the substrates of these isoenzymes.

Cobra Vega Extra Strong 120mg 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 Cobra Vega Extra Strong 120mg in combination with nitrates or nitric oxide donators is contraindicated. While taking α-adrenoblocker doxazosin (4 and 8 mg) and Cobra Vega Extra Strong 120mg (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 Vegah Extra 130 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.

Vegah Extra 120 Mg (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 Vega 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.

Cobra Vega Extra Strong 120 Mg (50 mg) does not cause an additional increase in bleeding time when taking acetylsalicylic acid (150 mg).

Cobra Vega Extra Strong 120mg (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 Signature Cobra Vega (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 Vegah Cobra in combination with antihypertensive agents does not lead to additional side effects.

Visual impairment

In rare cases, during post-approval use of all of the inhibitors of PDE5, including Cobra Vega Extra Strong 120mg, 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 Extra Strong 120mg 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 Cobra Vega Extra Strong 120mg, 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 120mg 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 Cobra Vega Extra Strong 120mg in patients with retinitis pigmentosa absent, so these patients should not be used Signature Cobra Vega (see "Contraindications").

Cardiovascular complications

During the post-marketing use of Sildenafil Tablets Vega Extra Cobra 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 Cobra Vega Extra Strong 120mg. 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 Extra without subsequent sexual activity. It is not possible to establish a direct link between the reported adverse events and those or other factors.

Hypotension

Vegah Extra 130 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 Cobra Vega Extra Strong 120mg, 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 Cobra Vega 120 and α-blockers can lead to symptomatic hypotension in some sensitive patients, Sildenafil 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 Cobra Vega Extra Strong 120mg should be started only after achieving stabilization of hemodynamic parameters in these patients. It should also consider reducing the initial dose of Extra Vega (see. "Dosage and administration"). The doctor should inform patients about what actions should be taken in case of symptoms of postural hypotension.
