Table 6: Mean QT and QTc changes in msec (90% CI) from baseline relative to placebo at 1 hour post-dose with different methodologies to correct for the effect of heart rate. Drug/Dose QT UncorrectedApproved by the FDA in 1998, sildenafil (Viagra) revolutionized the way we think about — and treat — erectile dysfunction (ED), largely because it is effective and easy to use. In 2003, the FDA approved two closely related drugs, vardenafil (Levitra) and tadalafil (Cialis). Five years later, in January 2008, low-dose Cialis for daily use came onto the market, creating an option that — theoretically, at least — makes having sex a possibility without advance planning.All three drugs work in a similar fashion, by affecting the normal physiology of the penis. In particular, they block PDE5, an enzyme that breaks down the erection-producing chemical cyclic guanosine monophosphate. This enables the penis to fill with blood and to stay erect long enough for intercourse. Of course, it’s important to realize that none of these drugs is an aphrodisiac. You must feel sexually aroused in order for them to work.The main differences between the three drugs have to do with timing: how quickly they begin to work, and how long their effects last (see Table 4). The biggest divide lies between Cialis for daily use, which keeps a steady supply of the drug in the bloodstream, and the as-needed dosing offered by the original form of Cialis, as well as by Levitra and Viagra. Among the nondaily pills, Levitra may start working slightly faster than Viagra (within a half-hour instead of an hour) although the FDA says that like Viagra, it should be taken about an hour before sexual activity. Some studies suggest that Levitra may help some men who don’t respond to Viagra. And while some doctors are skeptical about this claim, there’s no harm in trying Levitra or Cialis if Viagra doesn’t work for you.
