Other well known PDE5 inhibitors include Cialis, Viagra, sildenafil, Viagra Connect, and Tadalafil Daily. Organic or physical causes for sexual dysfunction in men include vascular, hormonal and neurologic factors. Since a straddle injury or use of a narrow saddle can obstruct and impair arteries to the penis, bicycle riding is also considered a risk factor for erectile dysfunction.

Subjects were administered a single dose of 0.4 mg sublingual nitroglycerin (NTG) at pre-specified timepoints, following their last dose of tadalafil (2, 4, 8, 24, 48, 72, and 96 hours after tadalafil). At 48 hours, by most hemodynamic measures, the interaction between tadalafil and NTGwas not observed, although a few more tadalafil subjects compared to placebo experienced greater blood-pressure lowering at this timepoint. After 48 hours, the interaction was not detectable ( see Figure 1). Just like Viagra and Sildenafil, Cialis contains a PDE5-inhibitor as the only active ingredient. PDE5 is a chemical which reduces your ability to gain an erection. PDE5-inhibitors block this particular chemical, which means that the arteries in your penis are more relaxed and the blood flow is increased.

Quantitative variables were presented in mean, standard deviation, minimum, and maximum. The Kruskal–Wallis test was used to compare quantitative variables between study groups. ODF tadalafil 5&nbsp
