Safety And Efficacy Of Sildenafil In Children With Pulmonary Arterial Hypertension
Pulmonary Arterial HypertensionHypertension1 morePulmonary arterial hypertension (PAH) is a rare, progressive, and life-threatening disease. In many patients, the course of PAH is a steady deterioration and reduced life expectancy. Sildenafil was approved by the European Commission for the treatment of PAH in pediatric patients in May 2011, making it the first agent to be approved for the treatment of children with PAH. The approval was based on the largest placebo-controlled study to be conducted in this population. The recommended dose in pediatric patients aged 1 year to 17 years old is 10 mg TID in patients ≤ 20 kg and 20 mg TID for patients > 20 kg. Higher doses are not recommended in pediatrics patients. This study is an open-label, multi-center study to investigate safety, efficacy and pharmacokinetics of sildenafil citrate in Japanese pediatric patients with PAH.

Ranolazine and Pulmonary Hypertension
AnginaPulmonary Arterial HypertensionThe purpose of the study is to determine if the medication, ranolazine (study drug), can help improve blood flow to your heart, increase your exercise capacity and improve your quality of life (QOL). For this study, you will be asked to perform several tests in order to determine if your heart function, exercise capacity, chest pain and QOL have improved after 3 months of treatment with ranolazine. Ranolazine is approved by the U.S. Food and Drug Administration (FDA) for the treatment of angina.
