    : The purpose of this retrospective study was to evaluate the safety and tolerability of transitioning pulmonary arterial hypertension (PAH) patients stable on sildenafil to tadalafil. This was assessed by adverse events (AEs), exercise capacity (6MWD), and the number of patients who were successfully transitioned. : PDE-5 inhibitors have been used to treat PAH since the approval of sildenafil in 2005. The approved dose of sildenafil is 20 mg TID, however, many patients require doses of 80-100 mg TID. This can result in patients taking 12-15 pills per day at substantial cost and inconvenience. Following approval of tadalafil in 2009, patients receiving sildenafil were switched to tadalafil at the time of insurance reauthorization or clinic visit to mitigate access, cost, and adherence issues. : Retrospective chart reviews were conducted on all patients who were stable on sildenafil for at least three months before transition to tadalafil. The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. 1 For the open label extension study, all patients received 80 mg tid. Listing a study does not mean it has been evaluated by the U. Following analysis of the data, the FDA approved 20 mg tid, indicating that "higher doses are not recommended" (Revatio PDR package insert). Sildenafil (Revatio) received approval for treatment of pulmonary arterial hypertension based upon the results of the SUPER1 study that randomized patients to sildenafil 20, 40 or 80 mg tid or matching placebo. Although there was no significant difference between dosing groups in the overall cohort with regard to 6 minute walk, patients with idiopathic PAH did have a greater hemodynamic effect at the 80 mg tid dose, raising the possibility that the maximum approved dose was not the maximally hemodynamically effective dose for at least some patient subsets. This has resulted in a confusing situation with some clinicians treating patients with sildenafil doses substantially above the FDA recommended dose, which creates issues of cost and insurance coverage. Some patients receive up to five 20 mg Revatio (sildenafil for PH) tablets tid, increasing cost fivefold (RPFrantz, unpublished data). Tadalafil (Adcirca) received FDA approval for treatment of PAH in May 2009, and will be available for this indication in August 2009.

    Tadalafil (Adcirca™) is a phosphodiesterase-5 inhibitor indicated for the treatment of pulmonary arterial hypertension (PAH) in World Health Organization (WHO) Group 1 patients in order to improve exercise ability. Studies establishing effectiveness included predominantly patients with WHO Functional Class II-III symptoms and etiologies of idiopathic or heritable PAH (61%) or PAH associated with connective tissue diseases (23%). Tadalafil is marketed as Adcirca® for PAH and was approved by the United States Food and Drug Administration (FDA) in 2009. Tadalafil is also marketed as Cialis® which is FDA approved for the treatment of erectile dysfunction but not for the treatment of PAH. Phosphodiesterase 5 (PDE-5) is a substance produced in the lungs and other parts of the body that breaks down (metabolizes) another substance called cyclic guanosine monophosphate (GMP). Cyclic GMP causes the blood vessels (arteries) to relax, that is, to widen. Tadalafil inhibits PDE-5, so that more cyclic GMP is available for the blood vessels inside the lungs to relax, leading to widening of the blood vessels. When you collect your prescriptions, check that you have been given the same brand of tablets as before. If the appearance is not the same as usual, speak with your doctor or pharmacist. The usual dose is 40 mg daily (taken as two 20 mg tablets). The most common side-effects are headache, flushing, nasal congestion, stomach upset, and muscle aches and pains. Primary pulmonary hypertension is a rare condition where there is too high a blood pressure in the blood vessels that supply your lungs from your heart. Tadalafil relaxes the muscle cells in the walls of the blood vessels to your lungs, allowing them to become wider (dilated). This reduces the pressure in these blood vessels and allows blood to flow more easily through them.
