NCT01683981

Brief Summary

Due to vasodilatory properties of the NO, one of the therapeutic approaches for IPAH is oral use of nitric oxide precursors (10). Efficacy of L-arginine is well-documented in the current literature but there is paucity of data with regard to L-citrulline- malate. Hence, this study will evaluate therapeutic efficacy of L-citrulline- malate in two categories of patients with pulmonary hypertension (IPAH, and Eisenmeger syndrome). This randomized clinical trial utilizes 6-minute walk, pro BNP levels and the echocardiographic indexes an indicator of functional improvement of the patients.
