When a diagnosis was reported, the participant was entered into a tracking system. Related medical records were requested with the participant’s permission and reviewed by physicians masked to exposure to confirm the diagnosis. For melanoma and SCC, we excluded self-reported cases that denied the diagnosis in the further follow-up or denied the permission to review their records, and only pathologically confirmed invasive cases in the medical record review were documented as the outcome. For BCC, we did not seek to obtain medical records for all cases, but previous studies have indicated a high validity of self-reports, with more than 90% of BCCs confirmed by histopathological records.25,26
One of the less common side effects associated with Viagra is a medical emergency known as priapism. Priapism is a painful erection lasting for more than four hours which requires immediate medical attention and treatment. Priapism may lead to permanent damage if left untreated, including the permanent loss of ability to have an erection. Levitra acts similarly to Viagra regarding possible side effects and onset and duration of pharmacologic action. However, Levitra is available at a lower dose and commonly causes dizziness. The typical recommended starting dose of Levitra is 10 mg and dosages can range from 5 mg to 20 mg depending on desired response and adverse reactions. Cialis differs from both Viagra and Levitra with regard to onset and duration of action. With treatment with Cialis, improvement in erectile function is possible for anywhere from 24 to 36 hours after administration of a dose, significantly longer than with Viagra. In addition, Cialis typically has a quicker onset of action and begins to work within approximately 30 minutes. Similar to Levitra, the recommended starting dose for Cialis, as needed, is 10 mg. Doses may range from 5 mg to 20 mg depending on efficacy and patient tolerability.

The frequency of patients reporting improvement of erections in response to a global question in four of the randomized, double-blind, parallel, placebo-controlled fixed dose studies (1797 patients) of 12 to 24 weeks duration is shown in Figure 7. These patients had erectile dysfunction at baseline that was characterized by median categorical scores of 2 (a few times) on principal IIEF questions. Erectile dysfunction was attributed to organic (58%; generally not characterized, but including diabetes and excluding spinal cord injury), psychogenic (17%), or mixed (24%) etiologies. Sixty-three percent, 74%, and 82% of the patients on 25 mg, 50 mg and 100 mg of Viagra, respectively, reported an improvement in their erections, compared to 24% on placebo. In the titration studies (n=644) (with most patients eventually receiving 100 mg), results were similar.

Additional, less frequent adverse reactions (<1%) reported in the controlled clinical trials of Cialis for BPH or ED and BPH included: gastroesophageal reflux disease, upper abdominal pain, nausea, vomiting, arthralgia, and muscle spasm.Of the total number of subjects in ED clinical studies of tadalafil, approximately 25 percent were 65 and over, while approximately 3 percent were 75 and over. Of the total number of subjects in BPH clinical studies of tadalafil (including the ED/BPH study), approximately 40 percent were over 65, while approximately 10 percent were 75 and over. In these clinical trials, no overall differences in efficacy or safety were observed between older (>65 and ≥75 years of age) and younger subjects (≤65 years of age). Therefore no dose adjustment is warranted based on age alone. However, a greater sensitivity to medications in some older individuals should be considered. [see Clinical Pharmacology (12.3)].With several FDA rejections and $50 million of investment already behind them, it will be interesting to see how Sprout and Even The Score will continue to frame the debate for "a female Viagra" if approval today is not forthcoming.
