Description
[Technical Field]
[0001] The present disclosure relates to methods, compositions and kits for the therapeutic treatment of idiopathic pulmonary fibrosis. The methods, compositions and kits include a combination product comprising a dry powder and an inhaler, The powder is intended to be administered to a patient by oral inhalation. [Background technology]
[0002] Idiopathic pulmonary fibrosis (IPF) is a chronic lung disease of unknown cause, and there is no cure for IPF. There is no healing. The disease is progressive and irreversible, causing scar tissue (fibrosis) to build up in the lungs. This causes the lungs to be unable to transport oxygen effectively into the bloodstream. It affects people between the ages of 50 and 70. It is a condition called interstitial lung disease (ILD). It belongs to the group of lung diseases that describe inflammation or scarring in the lungs. Signs and symptoms include shortness of breath and a persistent, dry cough. Subjects with IPF may experience difficulty eating or drinking. They may also experience loss of appetite and gradual weight loss. In individuals with IPF, the lungs become the organs and systems of the body. Scarring in the lungs increases over time until they can no longer provide enough oxygen to the tissues. do.
[0003] Currently, there are no surgical procedures or medications that can remove the progressive scarring of lung tissue. Therefore, it is important to learn good coping skills and educate patients about the disease. In particular, the treatment is designed to slow the progression of scar formation in the lungs, which is associated with the disease. However, these drugs may not necessarily reduce the associated symptoms of cough and shortness of breath. The oral tablet treatment has been shown to slow the progression of IPF. However, some patients Because of side effects, patients may be unable to tolerate these drugs at the doses needed to slow progression. The repeated high doses required to slow disease progression can cause gastrointestinal Adverse effects, such as nausea, diarrhea, abdominal pain, vomiting; hepatobiliary, nervous, vascular, metabolic and nutritional effects There are too many harmful effects, including disability.
[0004] There are several additional medications available that are useful for improving the symptoms of IPF, including shortness of breath and cough. Some of these medications include, for example, antacids to prevent gastroesophageal reflux and antihistamines to relieve shortness of breath. Oxygen therapy and exercise training to increase oxygen levels are also included. and their use to provide pulmonary rehabilitation for people with chronic conditions. Population education and support is recommended for subjects with IPF. One major and invasive procedure is to provide the patient with a lung transplant. To improve or offer alternative and novel methods of treatment to patients with IPF. It is necessary to provide
[0005] Drug delivery to pulmonary tissue is achieved using a variety of methods and routes of administration, including oral administration.
