CIALIS LEVITRA VIAGRA COMPARISON FAQ
Cialis Levitra and Viagra are all popular erectile dysfunction drugs. Vardenafil (Levitra, made by Bayer) and tadalafil (Cialis, made by Eli Lilly), gained FDA approval in 2003, whereas sildenafil (Viagra, made by Pfizer) is older, it was approved back in 1998. All the drugs are inhibitors of type 5 phosphodiesterase, and so share the same basic mechanism of sildenafil (Viagra). Inhibition of type 5 phosphodiesterase allows vasodilation in humans, hence the erectile properties of these drugs. All three are taken orally, in preparation for sexual activity. They all act to increase blood flow in the penis in response to sexual stimulation. However, there are important differences between cialis, levitra and viagra: differences of reaction to the body’s ingestion of food, onset of symptoms and duration of action.
Comparison of Cialis, Levitra and Viagra
There are some basic differences between the three drugs. For full details including a comparison table of the three drugs: Cialis levitra viagra FAQ. One thing to bear in mind with the summary table data, also available at Cialis viagra levitra compare, is that a lot more data is available on Viagra (more than 1000 peer-reviewed journal articles and 20,000,000 patients treated with Viagra), but the data on Cialis and Levitra is currently more sparse.
To summarise, efficacy is about 70% with all three prescription drugs. The side effect profile is similar among all three prescription medicines, except that, importantly Viagra users will very occasionally experience a blue hue to their vision, however the proportion of users this affects is minimal ( less thaan 0.5%). Cialis, Levitra and Viagra will all be unsuitable for men using organic nitrates. Cialis is reported to give muscle aches in approximately 5% of patients. Apart from that, typical mild side effects from vasodilation (flushing and headaches) are common to Cialis, Levitra and Viagra and only rarely caused men to quit the drugs’ clinical trials (2-3% failed to complete). Overall the half-life of Cialis is very noteworthy for its length (17.5 hours), earning Cialis its nickname ‘the weekender’: one single dose taken on Friday would probably still have an effect on Sunday night.
