Problems solved by technology

[0007] Although these drugs can alleviate the symptoms of PAH to a certain extent, pulmonary hypertension is still an incurable disease with a high mortality rate. The median survival time of patients under treatment is only 2.7 years. Therefore, it is particularly urgent to find new specific therapeutic drugs

Abstract

The invention belongs to the medical field and relates to the application of cannabidiol (CBD) in the treatment of pulmonary hypertension. The cannabidiol can be used as a sole active ingredient or incombination with other active ingredients to prepare a drug for treating pulmonary hypertension.The present invention relates to the use of any one of (1) to (3) below for the preparation of a medicament for the treatment and / or prevention of pulmonary hypertension:(1) cannabidiol, (2) a plant extract containing cannabidiol, preferably, the plant extract is a cannabis extract, and (3) a pharmaceutical composition comprising cannabidiol and one or more pharmaceutically acceptable adjuvants. The invention finds out the effect of cannabidiol on inhibiting pulmonary hypertension through experimental research, and is especially suitable for treating pulmonary hypertension caused by hypoxemia.

Description

technical field [0001] The invention belongs to the field of medicine and relates to the application of cannabidiol in the treatment of pulmonary hypertension. Background technique [0002] Pulmonary arterial hypertension (PAH) has complex etiology and is caused by a variety of heart, lung or pulmonary vascular diseases. Pulmonary arterial hypertension is characterized by pulmonary arteriolar vascular remodeling and pulmonary artery vascular smooth muscle proliferation, manifested by increased pulmonary circulation pressure and resistance, increased right heart load, right heart dysfunction, and reduced pulmonary blood flow, resulting in a series of clinical manifestations ; During the course of the disease, pulmonary hypertension often develops progressively. In particular, right heart failure caused by enhanced pulmonary artery vascular tension is a disease that seriously threatens human life and health. [0003] Pulmonary hypertension is divided into primary and seconda...
