We based our experiment on research done by Israeli scientist Ya'acov Leshem (link). Leshem was investigating ways to extend the shelf life of fruits, vegetables, and cut flowers by treating them with nitric oxide. The nitric oxide keeps plants fresh by inhibiting an enzyme that breaks down the chemical cyclic guanosine monophosphate (cGMP). Coincidentally, this is the same way that Viagra combats erectile dysfunction. When Leshem added a small amount of Viagra to water and placed cut flowers it, he found the flowers remained fresh and erect up to twice as long as untreated flowers. cialis jelly The table below lists the adverse reactions observed from spontaneous reporting and in placebo-controlled clinical trials (comprising a total of 7116 patients on CIALIS and 3718 patients on placebo) for on-demand and once-a-day treatment of erectile dysfunction and the once-a-day treatment of benign prostatic hyperplasia.

Study 1: This study was designed to evaluate the effect of 5 mg vardenafil compared to placebo when administered to BPH patients on chronic alpha-blocker therapy in two separate cohorts: tamsulosin 0.4 mg daily (cohort 1, n=21) and terazosin 5 or 10 mg daily (cohort 2, n=21). The design was a randomized, double blind, cross-over study with four treatments: vardenafil 5 mg or placebo administered simultaneously with the alpha-blocker and vardenafil 5 mg or placebo administered 6 hours after the alpha-blocker. Blood pressure and pulse were evaluated over the 6-hour interval after vardenafil dosing. For blood pressure (BP) results see Table 2. One patient after simultaneous treatment with 5 mg vardenafil and 10 mg terazosin exhibited symptomatic hypotension with standing blood pressure of 80/60 mmHg occurring one hour after administration and subsequent mild dizziness and moderate lightheadedness lasting for 6 hours. For vardenafil and placebo, five and two patients, respectively, experienced a decrease in standing systolic blood pressure (SBP) of >30 mmHg following simultaneous administration of terazosin. Hypotension was not observed when vardenafil 5 mg and terazosin were administered 6 hours apart. Following simultaneous administration of vardenafil 5 mg and tamsulosin, two patients had a standing SBP of <85 mmHg. A decrease in standing SBP of >30 mmHg was observed in two patients on tamsulosin receiving simultaneous vardenafil and in one patient receiving simultaneous placebo treatment. When tamsulosin and vardenafil 5 mg were separated by 6 hours, two patients had a standing SBP <85 mmHg and one patient had a decrease in SBP of >30 mmHg. There were no severe adverse events related to hypotension reported during the study. There were no cases of syncope.Mechanism of Action
Sildenafil (Viagra) is used to treat erectile dysfunction (impotence; inability to get or keep an erection) in men. Sildenafil (Revatio) is used to improve the ability to exercise in adults with pulmonary arterial hypertension (PAH; high blood pressure in the vessels carrying blood to the lungs, causing shortness of breath, dizziness, and tiredness). Children should not usually take sildenafil, but in some cases, a doctor may decide that sildenafil (Revatio) is the best medication to treat a child's condition. Sildenafil is in a class of medications called phosphodiesterase (PDE) inhibitors. Sildenafil treats erectile dysfunction by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection. Sildenafil treats PAH by relaxing the blood vessels in the lungs to allow blood to flow easily. cheap levitra At KwikMed, every Viagra? pill we sell has a pedigree which we can trace from manufacturer to distributor to our licensed pharmacy. Providing you with safe, genuine branded pharmaceuticals, is our top priority. Each package of Viagra? we sell is labeled with a series of unique numbers which allow us to track your medication through the supply chain.

They do this by affecting cGMP, the chemical involved in widening (dilating) the blood vessels when you are sexually aroused (described above). They are sildenafil (Viagra?), tadalafil (Cialis?), and vardenafil (Levitra?). You take a dose before you plan to have sex. Because of the way they work, these medicines are called phosphodiesterase type 5 (PDE5) inhibitors.Call your doctor or emergency room immediately if you accidentally took more LEVITRA than prescribed.
"Which brings up the exact same question that the FDA is faced with every time it decides whether a drug gets approved or not," Bloom writes. "Do the benefits outweigh the risks? The FDA has already said no three times. This should have been over with long ago." Cialis - Clinical PharmacologyCialis and Other Drug Interactions
