  • Erectile Dysfunction [hide all summaries]
    A number of drugs can cause sexual dysfunction in both women and men. Determining the potential benefits of vardenafil, tadalafil, or sildenafil is much more complex than for drugs that are used to treat cancer, heart disease, or high blood pressure, for example, where one of the potential benefits may be increased survival or avoidance of a heart attack or stroke. It is unlikely that untreated ED contributes to decreased survival, even though it may contribute to emotional distress and strained relationships.

  • Watch out for Interactions Between Drugs for Erectile Dysfunction and Other Medications [hide all summaries]
    (January 2009)
    The article lists 56 drugs that can interact with the three drugs for erectile dysfunction (ED): sildenafil (VIAGRA), tadalafil (CIALIS) and vardenafil (LEVITRA). Eight of the drugs are either nitrates such as nitroglycerin or a certain group of high blood pressure drugs.In combination with ED drugs, these drugs can cause a dangerous fall in blood pressure that could lead to a heart attack or stroke. Thirty-two other drugs can inhibit the enzyme that helps the body to eliminate the ED drugs, resulting in abnormally high blood levels of the drugs and a potentially harmful "overdose" even though you are actually taking the recommended amount. The other 16 drugs speed up the metabolism of the ED drugs, thereby lowering the blood levels and reducing the effectiveness of the ED drugs.

  • “Reminder” Ads: Innuendo Minus Information [hide all summaries]
    (November 2007)
    At present, facing increasing competition and dwindling sales, Pfizer has launched a “reminder” ad for Viagra that skirts FDA requirements. Because any ad that mentions the product’s name and the condition that it treats must also disclose its side effects, Pfizer has eclipsed its message with a song and an image. The song is “Viva Viagra” (to the tune of “Viva Las Vegas”) and the image is that of a jam session of guitar-playing 40-something-year-old men singing about their “not straying” and their devotion to an unseen “she.” The ad omits a caution against sexually transmitted diseases (STDs) and HIV, although this is flashed briefly on the screen. The result is an undermining of the pharmaceutical manufacturers’ original rationale for direct-to-consumer advertising: that it would be a tool to provide important information to patients who would benefit from the knowledge.
