In this blinded crossover trial, 23 subjects with stable coronary artery disease and evidence of exercise-induced cardiac ischemia were enrolled. The primary endpoint was time to cardiac ischemia. The mean difference in total exercise time was 3 seconds (tadalafil 10 mg minus placebo), which represented no clinically meaningful difference. Further statistical analysis demonstrated that tadalafil was non-inferior to placebo with respect to time to ischemia. Of note, in this study, in some subjects who received tadalafil followed by sublingual nitroglycerin in the post-exercise period, clinically significant reductions in blood pressure were observed, consistent with the augmentation by tadalafil of the blood-pressure-lowering effects of nitrates.25 mg - blue, rounded-diamond shaped tablets marked VGR 25 on one side and PFIZER on the other.

Ever since the FDA's April approval of Viagra, the little blue pill giving insurance companies a headache, the media have been infatuated with male impotence and its potential cure. U.S. pharmacists dispensed more than 215,000 Viagra prescriptions within the first four weeks of availability, sending manufacturer Pfizer Inc.'s stocks soaring and journalists buzzing. Everyone from porn magazine editors to former presidential hopefuls have expounded upon the supposed sociocultural impact of a wonderdrug clinically proven to, shall we say, make man's best friend stand up and salute the flag. swelling of tongue is there a generic for viagra

Most recently, 2 PDE5 inhibitors were shown to promote melanin synthesis,14 which may exacerbate melanoma development.15 These pieces of evidence prompted our hypothesis regarding the potential link between sildenafil use and melanoma.16Renal Impairment

The efficacy and safety of Cialis for once daily use for the treatment of the signs and symptoms of BPH was evaluated in 3 randomized, multinational, double-blinded, placebo-controlled, parallel-design, efficacy and safety studies of 12 weeks duration. Two of these studies were in men with BPH and one study was specific to men with both ED and BPH [see Clinical Studies (14.4)]. The first study (Study J) randomized 1058 patients to receive either Cialis 2.5 mg, 5 mg, 10 mg or 20 mg for once daily use or placebo. The second study (Study K) randomized 325 patients to receive either Cialis 5 mg for once daily use or placebo. The full study population was 87% White, 2% Black, 11% other races; 15% was of Hispanic ethnicity. Patients with multiple co-morbid conditions such as diabetes mellitus, hypertension, and other cardiovascular disease were included.Two studies were conducted to assess the efficacy of Cialis at a given timepoint after dosing, specifically at 24 hours and at 36 hours after dosing.are using amyl nitrite
