Background:In order to compare the effects of inhaled nitric oxide (NO) and magnesium (Mg) and their potential synergism on hemodynamics in pulmonary hypertension, we compared the effect of NO and Mg alone and in combination. The fact that simultaneous administration selectively increases pulmonary vascular relaxation would suggest that their association would allow for a decrease in the NO concentration required for optimal pulmonary vasodilation, thus lowering the risk of side effects.Material/Methods:We compared the effects of 20 ppm inhaled NO, 25 mg/kg Mg, and combined therapy in a pig model of hypoxic pulmonary hypertension. Twelve animals were randomly assigned to one of 3 treatment groups: control (group 1); Mg+NO group, receiving Mg followed by NO 15 min later (group 2); NO+Mg group, receiving NO followed by Mg 15 min later (group 3). The cardiac index, pulmonary and systemic pressures, pulmonary and systemic resistance, and the pulmonary to systemic resistance ratio (PVR/SVR) were recorded at baseline, on hypoxia and 15 minutes after each drug alone and in combination.Results:PVR/SVR decreased with NO alone (0.32±0.07 to 0.18±0.04; p
