According to preliminary results of the study, Viagra may help some patients suffering from high blood pressure in the lungs. In a study of 16 patients with pulmonary fibrosis, it has been found that sildenafil, sold under the brand name Viagra, reduces the pressure in the arteries supplying the lungs. High blood pressure in these vessels, known as hypertension, may occur as a result of pulmonary fibrosis, an inflammatory process that causes scarring of the lungs. In patients with this pathology capacity of the lungs to deliver oxygen is sharply limited. A new study published in the 21 edition of The Lancet, suggest that Viagra Canada is known for its vasodilating effects, may also reduce the pressure in the pulmonary arteries. Currently, the treatment of primary pulmonary hypertension (not caused by pulmonary or cardiac disease), is used vasodilators epoprostenol. However, it requires continuous intravenous administration, which is inconvenient and increases the risk of infection. When pulmonary hypertension occurs as a result of pulmonary fibrosis, drugs that cause vasodilation throughout the body, can increase hypoxia, improving blood flow to the affected areas of the lungs.
