Viagra (sildenafil) is an oral drug that is used for treating impotence

In North America, the problem has been mostly—though not entirely—restricted to “lifestyle” rather than life-saving drugs. Among these, the most famous is Pfizer’s Viagra, widely described as one of the most counterfeited drugs in the world. While it’s tempting to smirk at consumers duped by fake diet pills, baldness cures, and counterfeit Viagra, these drugs are stepping stones for counterfeiters. Criminals who find success here, experts say, will likely expand their business.viagra-price

If the medication is losing it’s effectiveness for you, you may want to consult your doctor for an alternative. Other medications that are in the same family and work in a similar manner are Cialis (tadalafil) and Levitra (vardenafil), but if one does not work as well for you anymore, another may work better. If your erection is painful or lasts for more than four hours (priapism), seek immediate medical attention, as permanent tissue damage and impotency could result.

One advantage Cialis has over Viagra Soft Tablets and Levitra is its 17.5-hour half-life (thus Cialis is advertised to work for up to 36 hours,[13] after which time there remains approximately 25 percent of the absorbed dose in the body) when compared to the four-hour half–life of sildenafil (Viagra).

The agency had rejected the drug twice in the past. Furthermore, the longer half-life is the basis for current investigation of tadalafil’s daily therapeutic use in relieving pulmonary arterial hypertension. Sildenafil is approved in several world regions as a thrice-daily therapy for pulmonary arterial hypertension. Viagra has systemic vasodilatory properties and may further lower blood pressure in patients taking anti-hypertensive medications.viagra-coupon

For two years, “Mike” bought counterfeit Viagra Price from Hitsman and sent samples to Amy Callanan, a senior scientist at Pfizer. Callanan, who works at Pfizer’s R&D campus in Groton, Connecticut, is now sitting with me at a large conference table scattered with baggies, blister packs, and bottles of pills. Callanan spends most of her time analyzing fake pharmaceuticals, looking for chemical clues that may lead investigators to culprits.

She picks up two small cardboard boxes. One box contains legitimate Viagra, the other is full of fakes. To me, they look almost identical: same size, same wide blue stripes down the left-hand side, legitimate-looking Pfizer logos and holograms. It worth more than $60. 50 mg of Viagra is often enough, so with our FREE pill splitter, you can quickly and easily turn one dose of Viagra into two!
