levitra vardenafil Nd statistically significant improvements in the EF Domain levitra vardenafil, SEP2 levitra vardenafil, and SEP3 scores compared to placebo. The mean baseline EF Domain score in these trials was 11.8. In a major North American fixed dose trial levitra vardenafil, 762 subjects were evaluated. The mean baseline EF Domain scores were 13 levitra vardenafil, 13 levitra vardenafil, 13 levitra vardenafil, 14 for the Levitra 5 mg levitra vardenafil, 10 mg levitra vardenafil, 20 mg and placebo groups levitra vardenafil, respectively. There was significant improvement at three months with Levitra (EF Domain scores of 18 levitra vardenafil, 21 levitra vardenafil, 21 levitra vardenafil, for the 5 mg levitra vardenafil, 10 mg and 20 mg dose groups levitra vardenafil, respectively) compared to the placebo group (EF Domain score of 15). The European trial of 803 subjects confirmed these results. In the North American trial levitra vardenafil, Levitra s levitra vardenafil.
levitra vardenafil Ignificantly improved the rates of achieving an erection sufficient for penetration (SEP2) at doses of 5 mg levitra vardenafil, 10 mg levitra vardenafil, and 20 mg compared to placebo (65% levitra vardenafil, 75% levitra vardenafil, and 80% levitra vardenafil, respectively levitra vardenafil, compared to a 52% response in the placebo at 3 months. The European trial confirmed these results. Side Effects Adverse events associated with the use of Levitra may include (but are not limited to) the following: Headache Flushing Rhinitis Dyspepsia Accidental Injury Sinusitis Flu Syndrome Dizziness Nausea Mechanism of Action Levitra is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). Erection of the penis is initiated by the relaxation of smooth muscle in the corpus cavernosum levitra vardenafil, one of a pair of sponge-like regions in the penis. When aroused levitra vardenafil, nitric oxide is released from nerve endings and endothelial cells in the corpus cavernosum. Nitric oxide activates the enzyme guanylate cyclase resulting in increased synthesis of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the corpus cavernosum. The cGMP triggers smooth muscle relaxation levitra vardenafil, increasing blood flow into the penis levitra vardenafil, resulting in erection.
