Hypersensitivity to the active substance or to any of the excipients of the drug.

When activating a link, NO/cGMP, which occurs under the influence of sexual stimuli, the suppression of PDE5 buy Caverta with bitcoin leads to increase of cGMP in the cavernous body. Thus, for the development of the desired pharmacological action of purchase Sildenafil Citrate for btc online pharmacy is required sexual stimulation.

Hereditary retinitis pigmentosa (see "Special instructions").

Caverta for btc (100 mg) has no effect on the pharmacokinetics of the HIV protease inhibitors, saquinavir and of pay for Sildenafil Citrate with bitcoinand that are substrates of the isoenzyme cytochrome CYP3A4, with their constant level in the blood.

In elderly patients dose adjustment is not required.

Grapefruit juice is a weak inhibitor of CYP3A4 and may moderately increase the concentration of buy Caverta (Sildenafil Citrate) with btc or credit card is in blood plasma.

It is known that how to buy Caverta with btc online pharmacy does not change the indicators of cardiac output and does not detract from the flow in stenotic coronary arteries.

Excipients: cellulose microcrystalline, croscarmellose sodium, hydroxypropyl cellulose, silica colloidal anhydrous, magnesium stearate, hypromellose, lactose, titanium dioxide (E 171), macrogol, sodium, Indigo (E 132).

Effects on ability to drive vehicles and mechanisms

In General, antihypertensive drugs (diuretics, beta-blockers, ACE inhibitors, antagonists of angiotensin II receptors blockers, vasodilators and Central acting), adrenergic blockers, calcium antagonists and blockers of alpha-adrenergic receptors did not reveal differences in the profile of side effects in patients receiving buy Caverta bitcoin compared to placebo.

Studies of the effect of the drug on the ability to drive vehicles and operate machinery was not carried out.

Statistically significant increase in test results of 6-minute walk was observed in the group of patients receiving 20 mg of Sildenafil Citrate for btc. For patients with LH functional class II and III test results improving the 6-minute walk adjusted for placebo, is 49 m and 45 m respectively.

The one-time admission drug dose to 800 mg in studies with healthy volunteers, adverse events were comparable to those when taking how to buy Caverta with bitcoin online pharmacy at lower doses, but their incidence and severity increased.

The drug is not intended for use in women (see "Contraindications").

Caution should be used in patients with arterial hypertension (blood pressure > 170/100 mm Hg. article.

The presence of such diseases as abnormal liver function, severe, hypotension (blood pressure below 90/50 mm Hg. St.), Recently moved stroke or myocardial infarction and known hereditary degenerative retinal disorders such as retinitis pigmentosa (a small number of these patients have genetic disorders of retinal PDE), because the how to buy Caverta with btc online pharmacy was not investigated in these subgroups of patients.

Realization of physiological mechanism of erection is associated with release of nitric oxide (NO) in the cavernous body during sexual stimulation. This, in turn, leads to increased levels of cGMP, the subsequent relaxation of smooth muscle of the cavernous body and increase blood flow.
