Background: Limited data are available on the prescription patterns and efficacy of antitussives and expectorants for patients with acute and chronic cough. This study examined the use and efficacy of these medications in a nationally representative sample of Korean patients.
Methods: We examined 4,206,016 individuals from the National Health Insurance Service (NHIS)-National Health Information Database (NHID) between 2015 and 2017. Among them, a sample of 10% (n=420,602) was retrieved for the diagnosis of respiratory diseases using the International Classification of Diseases, 10 edition (ICD-10; J00-J99), or the prescription of antitussives and expectorants for cough (ICD-10; R05). The acute cough group included those who were prescribed medications within 4 weeks of initial diagnosis (prescription within 14 days), whereas the chronic cough group included patients who were prescribed medications within 16 weeks of initial diagnosis (prescription within 56 days). If the prescription was discontinued or not changed to an alternative drug after the initial prescription, these cases were considered to have achieved symptom relief.
Results: This study included 288,460 patients (971,065 cases) with acute cough and 5,888 patients (15,399 cases) with chronic cough. 'Expectorants, excluding combinations with cough suppressants' had the highest prescription rates in both groups (acute cough, 63.8%; chronic cough, 61.7%), and showed the highest symptom relief regardless of the number of medications prescribed (acute cough, 84.3%; chronic cough, 70.4%).
Conclusions: 'Expectorants, excluding combinations with cough suppressants' were the most prescribed and effective medications for relieving cough symptoms in Korea patients. Further studies are needed to determine the optimal duration for using antitussives and expectorants in cough management.

Background: No previous studies have compared respiratory clinics and respiratory specialized facilities regarding causative diseases for bloody sputum and hemoptysis in Japan.
Methods: We retrospectively compared causative diseases for bloody sputum and hemoptysis between 3 respiratory clinics (clinic group) and 7 departments of respiratory medicine at hospitals (hospital group) in Japan.
Results: We collected data from 231 patients (median age, 51 years; age range, 24-96 years; 109 men (47.

Background: The efficacy of behavioral cough suppression therapy (BCST) for refractory chronic cough (RCC) and unexplained chronic cough (UCC) remains unclear due to limited evidence from small-scale single-center studies.
Objective: To compile and assess the quality of evidence from randomized controlled trials to evaluate the effectiveness of BCST.
Design: This study included randomized controlled studies and self-controlled studies related to BCST involving adult patients with RCC or UCC.

ATP-activated P2X3 receptors play a pivotal role in chronic cough, affecting more than 10% of the population. Despite the challenges posed by the highly conserved structure of P2X receptors, efforts to develop selective drugs targeting P2X3 have led to the development of camlipixant, a potent, selective P2X3 antagonist. However, the mechanisms of receptor desensitization, ion permeation, and structural basis of camlipixant binding to P2X3 remain unclear.

Yuebi Plus Banxia Decoction is derived from the Synopsis of the Golden Chamber(Jin Gui Yao Lue) by ZHANG Zhong-jing. With the effects of ventilating lung, discharging heat, descending adverse Qi, and relieving cough and asthma, this prescription is mainly used to treat pulmonary distension caused by phlegm heat obstructing the lungs. Currently, it is commonly used in clinical practice for the treatment of acute exacerbation of chronic obstructive pulmonary disease, acute bronchitis, pneumonia, bronchial asthma, pulmonary heart disease, and pertussis.
