Two of these subjects had a standing SBP < 85mmHg. Especially tell your healthcare provider if you take any of the following: medicines called guanylate cyclase stimulators, such as riociguat (Adempas) medicines called alpha blockers such as Hytrin (terazosin HCl), Flomax (tamsulosin HCl), Cardura (doxazosin mesylate), Minipress (prazosin HCl), Uroxatral (alfuzosin HCl), Jalyn (dutasteride and tamsulosin HCl), or Rapaflo (silodosin). The mean times (adjusted for baseline) to onset of limiting angina were 423.

There is a potential for cardiac risk of sexual activity in patients with preexisting cardiovascular disease. In a study of healthy male volunteers, co-administration of sildenafil at steady state (80 mg t. Studies have produced relevant data on the effects of VIAGRA on cardiac output. Two were discontinued after study period 1: one failed to meet pre-dose screening qualifications and the other experienced symptomatic hypotension as a moderately severe adverse event 30 minutes after dosing with open-label VIAGRA 50 mg. Ask your doctor if your heart is healthy enough to handle the extra strain of having sex.

Such an event may be a sign of non-arteritic anterior ischemic optic neuropathy (NAION), a rare condition and a cause of decreased vision including permanent loss of vision, that has been reported rarely post-marketing in temporal association with the use of all PDE5 inhibitors. It is uncertain whether PDE5 inhibitors directly cause the vision loss. VIAGRA is a phosphodiesterase-5 (PDE5) inhibitor indicated for the treatment of erectile dysfunction (ED) ( For most patients, the recommended dose is 50 mg taken, as needed, approximately 1 hour before sexual activity. In volunteers with severe (CLcr 65, hepatic impairment and severe renal impairment are associated with increased plasma levels of sildenafil. Safety of combined use of PDE5 inhibitors and alpha-blockers may be affected by other variables, including intravascular volume depletion and other anti-hypertensive drugs. On a global improvement question, 83% of patients reported improved erections on VIAGRA versus 12% on placebo. PDE5 Inhibitors or Other Erectile Dysfunction Therapies Sections or subsections omitted from the full prescribing information are not listed. VIAGRA was shown to potentiate the hypotensive effects of nitrates and its administration in patients who use nitric oxide donors such as organic nitrates or organic nitrites in any form is therefore contraindicated [ When VIAGRA is co-administered with an alpha-blocker, patients should be stable on alpha-blocker therapy prior to initiating VIAGRA treatment and VIAGRA should be initiated at 25 mg [ The recommended dose for ritonavir-treated patients is 25 mg prior to sexual activity and the recommended maximum dose is 25 mg within a 48 hour period because concomitant administration increased the blood levels of sildenafil by 11-fold [ Consider a starting dose of 25 mg in patients treated with strong CYP3A4 inhibitors (e. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Sexual activity can put an extra strain on your heart, especially if your heart is already weak from a heart attack or heart disease.

In many of the studies, of both fixed dose and titration designs, daily diaries were kept by patients. The type of adverse reactions in flexible-dose studies, which reflect the recommended dosage regimen, was similar to that for fixed-dose studies. An evaluation of visual function at doses up to twice the maximum recommended dose revealed no effects of VIAGRA on visual acuity, intraocular pressure, or pupillometry. One-third to one-half of the subjects in these studies reported successful intercourse at least once during a 4-week, treatment-free run-in period. Both sildenafil and the metabolite have terminal half lives of about 4 hours.

Most studies assessed the efficacy of VIAGRA approximately 60 minutes post dose. The mean steady state volume of distribution (Vss) for sildenafil is 105 L, indicating distribution into the tissues. Treatment with doxazosin continued for at least 7 days after dose period 1. Diary data indicated that on VIAGRA, 59% of attempts at sexual intercourse were successful compared to 13% on placebo. Individuals who have already experienced NAION are at increased risk of NAION recurrence.

VIAGRA is a phosphodiesterase-5 (PDE5) inhibitor indicated for the treatment of erectile dysfunction (ED) ( For most patients, the recommended dose is 50 mg taken, as needed, approximately 1 hour before sexual activity. Hemodynamic Data in Patients with Stable Ischemic Heart Disease after Intravenous Administration of 40 mg of Sildenafil In a double-blind study, 144 patients with erectile dysfunction and chronic stable angina limited by exercise, not receiving chronic oral nitrates, were randomized to a single dose of placebo or VIAGRA 100 mg 1 hour prior to exercise testing. There was no effect on sperm motility or morphology after single 100 mg oral doses of VIAGRA in healthy volunteers. In the third study, a single oral dose of VIAGRA 100 mg or matching placebo was administered in a 3-period crossover design to 20 generally healthy males with BPH. Larger effects were recorded among patients receiving concomitant nitrates [ Figure 1: Mean Change from Baseline in Sitting Systolic Blood Pressure, Healthy Volunteers. A total dose of 40 mg sildenafil was administered by four intravenous infusions. Following at least 14 consecutive daily doses of doxazosin, VIAGRA 100 mg or matching placebo was administered simultaneously with doxazosin. In dose period 1, subjects were administered open-label doxazosin and a single dose of VIAGRA 50 mg simultaneously, after at least 14 consecutive days of doxazosin. Subjects who had successfully completed the previous doxazosin interaction study (using VIAGRA 50 mg), including no significant hemodynamic adverse events, were allowed to skip dose period 1. At 24 hours the plasma levels of sildenafil were still approximately 200 ng/mL, compared to approximately 5 ng/mL when sildenafil was dosed alone.
