  Tetrandrine prevents monocrotaline-induced pulmonary arterial hypertension in rats through regulation of the protein expression of inducible nitric oxide synthase and cyclic guanosine monophosphate-dependent protein kinase type 1.

  Pulmonary arterial hypertension (PAH) is a fatal disease characterized by a persistent elevation of pulmonary artery pressure and ventricular hypertrophy. Tetrandrine is a bisbenzylisoquinoline alkaloid that can decrease blood pressure, inhibit the proliferation of vascular smooth muscle cells, and block cardiac hypertrophy, but whether it has a therapeutic effect on PAH remains poorly defined. This study was undertaken to investigate the efficacy of tetrandrine on PAH. ⋯ Tetrandrine alleviated MCT-induced PAH through regulation of nitric oxide signaling pathway and antioxidant and antiproliferation effects.
