Information

Cardiovascular complications

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

The pharmacokinetics of Vega Coin in the recommended dose range is linear.

Suction. After intake of Cobra Vega is rapidly absorbed. Absolute bioavailability averages about 40% (25 to 63%). In vitro Vegal Extra at a concentration of about 1.7 ng/ml (3.5 nm) inhibits the activity of PDE-5 50%. After a single dose of Sildenafil Vega Extra 130 Mg 100 mg average Cmax free Cobra Vega in plasma men is about 18 ng/ml (38 nm). Cmax when taking Cobra Vega inside fasting is achieved for an average of 60 minutes (from 30 to 120 minutes). When taken in combination with fatty foods, the rate of absorption decreases: Cmax decreases by an average of 29%, and Tmax increases by 60 minutes, but the degree of absorption does not change significantly (AUC decreases by 11%).

Distribution. The average Vss of Cobra 120 Vega Extra is 105 l. the Association of Cobra Vega and its main circulating N-demethyl metabolite with plasma proteins is about 96% and does not depend on the total concentration of the drug. Less than 0.0002% of the dose of Vega 120 Mg (an average of 188 ng) was found in sperm 90 minutes after taking the drug.

Metabolism. Vega Extra 120 is metabolized mainly in the liver by the action of CYP3A4 isoenzyme (main pathway) and CYP2C9 isoenzyme (minor pathway). The main circulating active metabolite, formed as a result of N-demethylation of Cobra Vega, undergoes further metabolism. The selectivity of this metabolite against PDE is comparable to that of Cobra Vega, and its activity against PDE-5 in vitro is about 50% of the activity of Cobra Vega. The concentration of the metabolite in the blood plasma of healthy volunteers was about 40% of the concentration of Cobra Vega. N-demethyl metabolite undergoes further metabolism; its T1/2 is about 4 no.

Breeding. The total clearance of Vegah Extra 130 is 41 l/h, and the final T1/2 — 3-5 h. After oral administration, as well as after I/V, Cobra Vega is excreted as metabolites, mainly by the intestine (about 80% oral dose) and to a lesser extent by the kidneys (about 13% oral dose).

Cardiovascular complications

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

Visual impairment

In rare cases, during post-approval use of all of the inhibitors of PDE5, including Cobra Vega, 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 of developing 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 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, in such patients should be used with caution and only in situations where the expected benefit outweighs the risk.

When using the drug Cobra Vega in doses exceeding the recommended, adverse events were similar to those noted above, but usually more common.

*Side effects identified during post-marketing studies.

Interaction

Effect of other drugs on the pharmacokinetics of Cobra Vega

The metabolism of Vega Pills occurs mainly under the action of CYP3A4 isoenzyme (main pathway), so inhibitors of this isoenzyme can reduce the clearance of Cobra Vega, and inducers, respectively, increase the clearance of Cobra Vega 120 Mg. A decrease in the clearance of Vega Extra Cobra 120 with simultaneous use of inhibitors of CYP3A4 isoenzyme (ketoconazole, erythromycin, cimetidine).

Cimetidine (800 mg), a nonspecific inhibitor of CYP3A4 isoenzyme, when taken together with Vega Cobra 120 (50 mg) causes an increase in the concentration of Vegal Extra in plasma by 56%.

A single dose of 100 mg of Vega Extra Cobra together with erythromycin (500 mg/day 2 times a day for 5 days), a moderate inhibitor of CYP3A4 isoenzyme, while achieving a constant concentration of erythromycin in the blood, leads to an increase in the AUC of Cobra Vega by 182%.

When co-administered Cobra Vega (once 100 mg) and saquinavir (1200 mg/day 3 times daily), an inhibitor of HIV protease and of CYP3A4, on the background to achieve a constant concentration of saquinavir in the blood, Cmax of Vegah Extra 130 was increased by 140% and the AUC increased by 210%.

Stronger inhibitors of CYP3A4 isoenzyme, such as ketoconazole and Itraconazole, can cause more pronounced changes in the pharmacokinetics of Cobra Vega Extra Strong 120 Mg.

The simultaneous use of Cobra Vega (100 mg once) and ritonavir (500 mg 2 times a day), an inhibitor of HIV protease and a strong inhibitor of cytochrome P450, on the background to achieve a constant concentration of ritonavir in the blood leads to an increase in Cmax of Cobra Vega 120 Mg by 300% (4 times), a AUC by 1000% (11-fold). After 24 h, the concentration of Vega Extra Cobra 130 Mg in blood plasma is about 200 ng/ml (after a single application of one Cobra Vega — 5 ng/ml). This is consistent with the ritonavir effect on a wide range of cytochrome P450 substrates. Vega Extra Cobra 120 does not affect the pharmacokinetics of ritonavir. Given these data, the simultaneous reception of ritonavir and Cobra Vega is not recommended. In any case, the maximum dose of Cobra Vega under any circumstances should not exceed 25 mg for 48 hours. If Sildenafil Vega Extra 120 is taken in the recommended doses, patients receiving strong inhibitors of CYP3A4 isoenzyme at the same time, then Cmax free Cobra Vega does not exceed 200 nm, and the drug is well tolerated.

Single administration of antacid (magnesium hydroxide/aluminum hydroxide) does not affect the bioavailability of Vega Extra Strong 120.

Studies involving healthy volunteers with simultaneous use of endothelin receptor antagonist, bosentan (CYP3A4 isoenzyme inducer (moderate), CYP2C9, and possibly CYP2C19) in Css (125 mg 2 times a day) and Cobra Vega in Css (80 mg 3 times a day) showed a decrease in AUC and Cmax Sildenafil Tablets Vegah Extra Cobra by 62.6 and 52.4%, respectively. Cobra Vega increased the AUC and Cmax of bosentan by 49.8 and 42%, respectively.

It is assumed that the simultaneous use of Vegal Extra with powerful inducers of CYP3A4 isoenzyme, such as rifampicin, can lead to a greater decrease in the concentration of Cobra Vega in blood plasma.

CYP2D6 isoenzyme inhibitors (SSRIs, tricyclic antidepressants), thiazide and thiazide-like diuretics, ACE inhibitors and calcium antagonists have no effect on the pharmacokinetics of Vega Cobra 120.

Azithromycin (500 mg/day for 3 days) has no effect on AUC, Cmax, Tmax, excretion rate constant and T1/2 Cobra Vega or its main circulating metabolite.

Vega 120 Mg 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.

Vegah Extra 120 Mg 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 Cobra Vega 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. Cobra Vega 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 Cobra Vega is sexual stimulation.

Vegah Cobra restores impaired erectile function in conditions of sexual stimulation by increasing blood flow to the cavernous bodies of the penis.
