COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

01:20Chronic Obstructive Pulmonary Disease-I: Introduction
3.0K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

6.1K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Summary
Chronic cough, defined as lasting over 8 weeks, significantly impacts quality of life. New P2X3-antagonist drugs offer a promising, potentially safer treatment for chronic refractory cough (CRC) compared to current options.
Area of Science:
- Respiratory Medicine
- Pharmacology
Background:
- Chronic cough, lasting over 8 weeks, affects 10.9% of the population in the Netherlands.
- Cough hypersensitivity describes an over-reactive cough reflex to stimuli.
- Unexplained chronic cough (UCC) and chronic refractory cough (CRC) are distinct phenotypes requiring specific management.
Purpose of the Study:
- To review the current treatment landscape for chronic refractory cough (CRC).
- To introduce novel P2X3-antagonist therapies for CRC.
- To highlight the potential benefits of P2X3-antagonists in managing cough hypersensitivity.
Main Methods:
- Literature review of chronic cough definitions and prevalence.
- Analysis of current therapeutic strategies for CRC, including neuromodulating drugs.
Main Results:
- Neuromodulating drugs are the primary treatment for CRC but are limited by side effects and variable efficacy.
- P2X3-antagonists target a late phase of the cough reflex.
- P2X3-antagonists show potential for reduced side effects compared to existing CRC treatments.
Conclusions:
- Effective management of chronic refractory cough remains a challenge.
- P2X3-antagonists represent a novel therapeutic approach for CRC.
- Targeting cough hypersensitivity with P2X3-antagonists may improve patient outcomes and quality of life.
