    Tadalafil and pulmonary hypertension


    After many years under patent protection, the generic medication Tadalafil will soon be available. Hopefully generic Tadalafil will be much less expensive than Adcirca. We can look back at what happened with a similar medicine, Revatio, when it went generic as sildenafil. We don’t know precise pricing but we expect deep discounts relative to the $25-40,000 price tag. Typically prices continue to drop as more generic manufacturers enter the market. Once there are more than three generic manufacturers, prices can drop profoundly. For example, branded Revatio was more than $10 per pill prior to release of generic sildenafil. Currently sildenafil costs about $0.40 per pill without any insurance. (tadalafil) is an approved therapy to reduce the symptoms of pulmonary arterial hypertension (PAH) and increase the exercise ability of patients. Adcirca was developed originally by Eli Lilly, which holds the marketing rights to the product in Europe. PAH is associated with a narrowing of the blood vessels (vasoconstriction) in the lungs, leading to high blood pressure and an inability to effectively transport oxygen around the body due to reduced blood flow. One cause of this is low levels of a molecule called c GMP, which is involved in the relaxation of the smooth muscles of the artery walls. Blocking PDE-5 means that c GMP is not cleared as quickly, resulting in an increase in c GMP. Higher levels of c GMP relax the smooth muscles of the arteries, leading to vasodilation and a reduction of blood pressure. This randomized, double-blind, placebo-controlled Phase 3 study, investigated how effectively Adcirca improved a patient’s ability to exercise at one of four different doses, compared to a placebo. The main outcome was the change in the distance the patient could walk in six minutes after 16 weeks of treatment.

" May 29, 2009 -- The FDA has approved a new use for tadalafil, which is the active ingredient in the erectile dysfunction drug Cialis. Tadalafil, sold as Adcirca, is now approved to improve exercise ability in people with pulmonary arterial hypertension, which is a rare, life-threatening lung disorder that causes high blood pressure in the lungs. Adcirca comes in 40 milligram tablets; patients take one tablet per day. In 2005, the FDA approved Revatio, a pulmonary arterial hypertension drug made with sildenafil, the active ingredient in the erectile dysfunction drug Viagra. The FDA approved Adcirca based on a clinical trial in which pulmonary arterial hypertension patients either took Adcirca (given as two daily tablets, with each tablet containing 20 milligrams of tadalafil) or a placebo pill for 16 weeks. Revatio pills are taken three times daily at 20 milligrams per pill. At the end of the study, the patients walked for six minutes; during that time, patients taking Adcirca walked 33 meters farther than patients in the placebo group. Cialis, a drug marketed to treat erectile dysfunction and benign prostatic hyperplasia in men, is also effective in treating pulmonary hypertension. A number of studies have investigated the uses for phosphodiesterase-5 (PDE5) inhibitors beyond the treatment of erectile dysfunction. Pulmonary hypertension is an ideal disease candidate for such studies as the smooth muscle cells of the lungs also produce PDE5. Pulmonary hypertension is a progressive and chronic condition that usually arises out of an underlying disease such as chronic lung or heart disease. It involves the vasoconstriction of the blood vessels within the lungs, which increases the pressure at which the blood flows through. Over time, the increased blood pressure causes fibrosis or thickening in those vessels, which further impairs blood flow and increases blood pressure. Extremely high blood pressure in the lung vasculature results in difficulty in breathing and shortness of breath, fatigue, peripheral edema or swelling of the extremities, dizziness and fainting.
