Generic Viagra: Is It Really Cheap In The End?

In this current study we investigated the effect of sildenafil on retinal vessel diameter in patients with AMD. Sildenafil citrate produced statistically significant dilatation of major retinal veins at 90, 180 and 300 min in this group of patients. The effect of sildenafil on the retinal vessel diameters of AMD patients has not been studied before. Our previous study on the effects of sildenafil on the choroidal circulation of AMD patients did not show any statistically significant differences in the choroidal blood flow parameters after administration of sildenafil or placebo at any of the time points

Mean retinal venous diameters at baseline, 30, 90, 180 and 300 min for sildenafil and placebo treatments are shown in (Table 1, Fig. 2). An analysis of variance (ANOVA) comparing the effects of sildenafil citrate and placebo on retinal veins diameters showed a significant interaction between time and treatment (P ¼ 0.03), therefore, comparisons of both treatments at each time point were performed.

Fourteen male AMD patients (13 Caucasians and 1 African-American) with a mean age of 75
7 years (
1SD) were included in this double-masked, randomized, placebocontrolled, crossover study. AMD features of enrolled patients were similar or worse than those present in eyes graded as AMD category 3 in the AREDS study. Only one eye of each patient was included in the study.

Sildenafil citrate (viagra), the first oral drug approved for the treatment of erectile dysfunction, selectively inhibits phosphodiesterase 5 (PDE5), the isozyme that metabolizes cyclic guanosine monophosphate (c-GMP) in the corpus cavernosum (Boolell et al., 1996). In addition to the corpus cavernosum smooth muscle, PDE5 is also found in other human tissues including vascular smooth muscle (Pfizer, Investigative Brochure). Endothelium-derived relaxing factors, such as nitricoxide (NO) (Furchgott and Vanhoutte, 1989; Ignarro et al., 1987) produce smooth muscle relaxation and dilatation of blood vessels due to the increase in levels of cGMP

Sex, drugs and animal parts - References

Sexual impairment is common after a traumatic brain injury. Both decreased and increased sexual desire have been reported. In women endocrine abnormalities are the most sensitive predictors of sexual dysfunction (Hibbard et al 2000). In males both impotence and retarded ejaculation have been reported (Meyer 1955, Kreutzer & Zasler 1989). Sexual dysfunction in patients with brain lesions and encephalopathies

Many species of plants and animals are used in traditional Chinese medicine (TCM) to treat impotence (typically erectile dysfunction [ED]; Bensky & Gamble 1993). Some of these taxa are overharvested for their medicinal uses and are now threatened. Efforts to conserve many of these taxa have failed because the market forces driving their commercial collection or poaching remain in place. Shortly after Viagra appeared on the market in 1998, we suggested that Viagra has the potential to eliminate demand for animal sexual potency products (von Hippel & von Hippel 1998). We suggested that the East Asian market in animal potency products could soon fall victim to Viagra’s success because Viagra is less expensive than many of these animal products (Viagra costs US$ 8-10 per pill in the countries in which it is legalized) and Viagra’s effectiveness is demonstrated (Giuliano et al. 1997; Morales et al. 1998; Sadovsky et al. 2001) rather than hoped for.
