    Sildenafil half life


    I am proscribed 25mg of viagra which I buy as 50mg pills to save money and cut in half. Cutting a viagra in half is not easy because they are hard coated and not scored (and oddly shaped). I find that 25mg is a little too much since it has side effects (a low blood pressure feeling, even though I don't think my blood pressure is really low). I have tried cutting the 50mg into fourth (very difficult), but this seems like a little too little. Unfortunately on the few times that I have forgone the viagra I have experienced moderate impotence for the first time in my life. I am able to achieve a half-erection but it is hard to maintain long enough to have an orgasm. When I occasionally masturbate at home, without using viagra, I achieve a rapid erection and orgasm as I've always done since I was 14 years old. I ask because the Lipitor fullpage ads in national magazines say DO NOT BREAK TABLETS and they Lipitor website from Pfizer also says on the meds page DO NOT BREAK TABLETS but my doctor told me to break the 10 mg tabs in half and take just half each day.

On November 21, 2003 the FDA approved tadalafil (as Cialis) for sale in the United States as the third ED prescription drug pill (after sildenafil citrate (Viagra) and vardenafil (Levitra)). Like sildenafil and vardenafil, tadalafil is recommended as an 'as needed' medication. Tadalafil was approved in May 2009 in the United States for the treatment of pulmonary arterial hypertension and is under regulatory review in other regions for this condition. In late November 2008, Eli Lilly sold the exclusive rights to commercialize tadalafil for pulmonary arterial hypertension in the United States to United Therapeutics for an upfront payment of $150 million.
