Embodiment 1

[0019] Ibrutinib is added with pharmaceutically acceptable excipients and prepared into various dosage forms according to conventional methods, such as various specifications of liquid injections, powder injections, emulsions for injection, tablets, pills, capsules, ointments, creams, patches , Liniments, powders, sprays, implants, drops, suppositories, ointments, confectionery, etc.

[0020] The route of administration of Ibrutinib includes various routes of administration: oral administration, injection administration, implant administration, intracavity administration, sublingual administration, anal administration, transdermal administration, internal and external application, etc. .

experiment example 1

[0022] In order to prove the technical means, purpose and experimental effect of the experimental invention, the following will further illustrate the present invention with specific experimental examples.

[0023] (1) Experimental materials

[0024] 1. Laboratory animals

[0025] SD rat, male, 350±10g, purchased from Beijing Weitonglihua Laboratory Animal Technology Co., Ltd. The experimental animals were placed in the modeling area for 7 days after they were purchased.

[0026] Animal feeding conditions: constant temperature 25±1℃, constant humidity 55±5%, keep light and dark for 12 hours each, feed and water normally.

[0027] 2. Experimental drugs and configuration methods:

[0028] Ibrutinib (ibrutinib), purchased from Selleck, storage conditions: 4°C, protected from light. Ibrutinib 22.5 mg was accurately weighed, stirred until it was completely dissolved in 25 μl DMSO, diluted with 2.5 ml of saline, and stored.

[0029] (2) Experimental method

[0030] 1. Model construction and dr...

Abstract

The invention discloses application of ibrutinib in preparation of drugs for treating chronic hypoxic pulmonary hypertension. The experimental result shows that rising of right ventricular pressure can be significantly alleviated by using the ibrutinib to treat rats in a hypoxic group, an HE staining result shows that the thickness increasing degree of pulmonary artery medial membranes of the ratsin the hypoxic group treated by the ibrutinib is alleviated, and the number of muscularized arterioles is decreased significantly. The ibrutinib can provide a potential treatment prospect for treatment of the chronic hypoxic pulmonary hypertension.

Description

Technical field [0001] The invention belongs to the technical field of application of ibrutinib, and in particular relates to the use of ibrutinib in preparing a medicine for treating chronic hypoxic pulmonary hypertension. Background technique [0002] Pulmonary hypertension is a chronic and complex cardiopulmonary vascular disease caused by multiple factors. Its main pathological features are increased pulmonary artery pressure, pulmonary resistance vascular proliferation and structural remodeling. Patients with pulmonary hypertension often go to a doctor late. Once diagnosed, such patients often develop right heart failure and even die within a few years. Patients with pulmonary hypertension have a poor prognosis, low long-term survival rate, and high case fatality rate. It has become a public health event endangering human health. [0003] Chronic hypoxic pulmonary hypertension is the third type classified by the European Society of Cardiology. It is the cause of respiratory d...
