Information

The pharmacokinetics of Buy Kamagra Bitcoin in the recommended dose range is linear.

Suction. After intake of Buy Kamagra Bitcoin is rapidly absorbed. Absolute bioavailability averages about 40% (25 to 63%). In vitro Buy Kamagra Bitcoin at a concentration of about 1.7 ng/ml (3.5 nm) inhibits the activity of PDE-5 50%. After a single dose of Buy Kamagra Bitcoin 100 mg average Cmax free Buy Kamagra Bitcoin in plasma men is about 18 ng/ml (38 nm). Cmax when taking Buy Kamagra Bitcoin 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 Buy Kamagra With Bitcoin is 105 l. the Association of Buy Kamagra Bitcoin 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 Buy Kamagra Bitcoin (an average of 188 ng) was found in sperm 90 minutes after taking the drug.

Metabolism. Buy Kamagra Bitcoin 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 Buy Kamagra Bitcoin, undergoes further metabolism. The selectivity of this metabolite against PDE is comparable to that of Viagra Bitcoin Pharmacy Online, and its activity against PDE-5 in vitro is about 50% of the activity of Buy Kamagra Bitcoin. The concentration of the metabolite in the blood plasma of healthy volunteers was about 40% of the concentration of Buy Kamagra Bitcoin. N-demethyl metabolite undergoes further metabolism; its T1/2 is about 4 no.

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

Clinical data

In a placebo-controlled cross-examination of patients with proven early age macular degeneration (n=9), Buy Kamagra Bitcoin 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 Buy Kamagra With Bitcoin 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 Buy Kamagra Bitcoin, 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 Buy Kamagra Bitcoin 25 mg), 74% (dose Generic Viagra For Bitcoin 50 mg) and 82% (dose Buy Kamagra Bitcoin 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 Generic Viagra For Bitcoin 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 Buy Kamagra Bitcoin.

Pharmacokinetics

Cardiovascular complications

During the post-marketing use of Buy Kamagra Bitcoin 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 Buy Viagra With Bitcoins. 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 Buy Viagra With Bitcoins 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 Buy Kamagra Bitcoin, 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 Buy Kamagra Bitcoin 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 Buy Kamagra Bitcoin, in such patients should be used with caution and only in situations where the expected benefit outweighs the risk.

When using the drug Buy Kamagra Bitcoin 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 Buy Kamagra Bitcoin

The metabolism of Buy Kamagra Bitcoin occurs mainly under the action of CYP3A4 isoenzyme (main pathway), so inhibitors of this isoenzyme can reduce the clearance of Buy Kamagra Bitcoin, and inducers, respectively, increase the clearance of Buy Viagra With Bitcoin Or Credit Card. A decrease in the clearance of Buy Kamagra Bitcoin with simultaneous use of inhibitors of CYP3A4 isoenzyme (ketoconazole, erythromycin, cimetidine).

Cimetidine (800 mg), a nonspecific inhibitor of CYP3A4 isoenzyme, when taken together with Pay For Sildenafil With Bitcoin (50 mg) causes an increase in the concentration of Buy Kamagra Bitcoin in plasma by 56%.

A single dose of 100 mg of Buy Kamagra Bitcoin 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 Buy Sildenafil With Bitcoins by 182%.

When co-administered Buy Kamagra Bitcoin (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 Buy Viagra Bitcoin 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 Buy Kamagra Bitcoin.

The simultaneous use of Purchase Viagra For Bitcoin Online Pharmacy (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 Buy Kamagra Bitcoin by 300% (4 times), a AUC by 1000% (11-fold). After 24 h, the concentration of Buy Viagra Online Bitcoin Or Credit Card in blood plasma is about 200 ng/ml (after a single application of one The Purchase Of Extra Super Viagra — 5 ng/ml). This is consistent with the ritonavir effect on a wide range of cytochrome P450 substrates. Buy Kamagra Bitcoin does not affect the pharmacokinetics of ritonavir. Given these data, the simultaneous reception of ritonavir and Generic Female Viagra For Bitcoin is not recommended. In any case, the maximum dose of Buy Kamagra Bitcoin under any circumstances should not exceed 25 mg for 48 hours. If Pay For Female Viagra With Bitcoin is taken in the recommended doses, patients receiving strong inhibitors of CYP3A4 isoenzyme at the same time, then Cmax free Generic Viagra For Bitcoin 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 Buy Kamagra Bitcoin.

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 Sale Super Viagra Accept Bitcoin in Css (80 mg 3 times a day) showed a decrease in AUC and Cmax Buy Kamagra Bitcoin by 62.6 and 52.4%, respectively. Buy Kamagra With Bitcoin increased the AUC and Cmax of bosentan by 49.8 and 42%, respectively.

It is assumed that the simultaneous use of Buy Kamagra Bitcoin with powerful inducers of CYP3A4 isoenzyme, such as rifampicin, can lead to a greater decrease in the concentration of Buy Kamagra Bitcoin 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 Buy Kamagra Bitcoin.

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

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 Buy Kamagra Bitcoin. 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 Buy Viagra Online Bitcoin Or Credit Card, consult a doctor immediately.

Bleedings

Sale Super Viagra Accept Bitcoin enhances the antiplatelet effect of sodium nitroprusside, a nitric oxide donator, on human platelets in vitro. Data on the safety of Buy Kamagra Bitcoin in patients with a tendency to bleeding or exacerbation of gastric ulcer and duodenal ulcer are not available, so the drug Buy Kamagra Bitcoin 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 (Pay For Female Viagra With Bitcoin — 12.9%, placebo — 0%) than in patients with primary pulmonary arterial hypertension (Buy Kamagra Bitcoin — 3%, placebo — 2.4%). Patients receiving Discount Red Viagra With Bitcoin 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 Buy Viagra With Bitcoins together with other PDE-5 inhibitors or other drugs for the treatment of pulmonary hypertension containing Buy Sildenafil With Bitcoin (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").
