Restraint/Challenge

“Limited Treatment Efficacy and Side Effects of Existing Therapies”

• The limited efficacy of currently available treatment options remains one of the most significant challenges in the chronic cough market, particularly for patients suffering from refractory or unexplained chronic cough
• Many conventional therapies, including antihistamines, corticosteroids, bronchodilators, and proton pump inhibitors, often fail to provide adequate or consistent relief, highlighting a substantial unmet medical need
• For instance, a considerable proportion of patients continue to experience persistent coughing despite undergoing multiple lines of treatment, which can negatively impact quality of life and increase healthcare burden
• The complexity and multifactorial nature of chronic cough make accurate diagnosis difficult, often resulting in trial-and-error treatment approaches that delay effective management
• In addition, commonly used medications are associated with side effects such as drowsiness, fatigue, dizziness, dry mouth, and gastrointestinal disturbances, which can reduce patient adherence to treatment regimens
• Long-term use of certain therapies may also raise concerns regarding safety and tolerability, particularly among elderly patients and those with comorbid conditions
• The absence of universally accepted clinical guidelines for the management of chronic cough further complicates treatment standardization across healthcare settings
• Limited awareness in some regions and underdiagnosis of chronic cough cases continue to restrict market penetration
• High costs associated with novel and advanced therapies may also pose a barrier to access, especially in low- and middle-income countries
