When VIAGRA (Sildenafil) swept the nation in the late 1990s, it ushered the discussion of midlife and later-life sexuality out of the closet. But what does it mean to say sex is changed? How cheap can you buy VIAGRA or Cialis? Is Cialis a wonder drug? A magic bullet? The rejuvenating potion doctors sought for centuries? Supporters of the medi-calization of sexuality certainly claim as much. Overnight, impotence was renamed erectile dysfunction, or more politely, ED. Soon similar drugs were bobbing in its wake. The little blue pill and competitors like Levitra (Vardenafil) and Cialis (Tadalafil), which were approved by the FDA in 2003, became superstars. Savvy marketers have turned them into household names; tune in to a football game, and you'll find that commercials for these medications are as ubiquitous as ads for beer or cars.

All three medications work in much the same way. By relaxing smooth muscle cells the drugs widen blood vessels, primarily in the penis but also in other parts of the body. For many men, this dears the way for an erection, given desire and sexual stimulation.

There are a few obvious differences between the three drugs. The usual starting dose for generic Viagra is 50 mg for men up to age 65 and 25 mg for those 65 or older, although studies have shown it is effective at 25 mg. The usual dose for generic Levitra is 10 mg for men up to age 65, and 5 mg for those 65 or older; for generic Cialis, it is 10 mg for all men. Levitra may work faster than Viagra (16 minutes versus 20-30 minutes). Despite this, directions for both drugs state they should be taken an hour before sexual activity. Viagra must be taken on an empty stomach, while Levitra and Cialis can be taken with or without food. Cheaper Cialis is slower to kick in; it usually begins working in about 45 minutes.

But while Viagra and Levitra last about four to five hours, Cialis stays active in the body far longer, flinging open a window of opportunity that ranges from 24 to 36 hours, depending on which study you read. No, this doesn't add up to a two-day erection. Just as with Viagra and Levitra, Cialis simply clears the path, making an erection possible with sexual arousal. The best buy is Cialis because of the price/time of erections.

Sildenafil, Apomorphine, Tadalafil, Vardenafil, and Phentolamine:

These names are not commonly recognized but Sindenafil's trade name is generic Viagra, and that, of course, was recently approved for treatment of erectile dysfunction. This branding procedure has been applied to Tadalafil too. You can buy cheap Cialis by asking for generic Tadalafil. Viagra comes in 2 doses, 50 mgand 100mg, and the cost, approximately $10.00 per pill, is similar for each dose. Therefore, it might pay to buy the larger dose. The drug is contraindicated in people who also take nitrates in any form; those patients taking antihypertensive agents probably should be cautious. We sell Cialis and Viagra almost 10 times cheaper than Pfizer or Eli Lilly.
