Chronic Refractory Cough Understanding and Treatment Algorithm
Chronic Refractory Cough Overview
Chronic Refractory Cough (CRC) is defined as a cough lasting more than 8 weeks despite guidelines-based treatment and which may be treated only by different medical specialties. Individuals with CRC have impaired quality of life and interruption of activities of daily living. It also results in depression and can persist for many months or years, despite systematic investigation and treatment of known causes. The infection can also be referred to as chronic cough (CC), chronic idiopathic cough (CIC), unexplained chronic cough (UCC), and cough hypersensitivity syndrome (CHS).
Recurrent incidence of CC results in CRC. The symptoms and indications of CRC are similar to those of CC. One of the first and most important symptoms that may indicate respiratory involvement is a persistent or chronic cough. Key symptoms include a dry irritated cough localized around the laryngeal region. Symptoms are not restricted to cough and can include globus, dyspnea, and dysphonia. CRC has factors in common with laryngeal hypersensitivity syndromes and chronic pain syndromes, and these similarities help to shed light on the pathophysiology of the condition.
Laryngopharyngeal reflux (LPR) is a common cause of CRC and may be present without symptoms of classic GERD, including heartburn (silent reflux). Obstructive sleep apnoea syndrome (OSAS) is also an independent risk factor for CC and a risk factor for LPR/GERD recalcitrant to medical therapy. ACE inhibitors are another common cause of CRC, which can occur spontaneously even after many years on this medication without previous problems.
CC is more prevalent in women, and there are various complications associated with it which include negative psychological, social, and physical outcomes. It causes an interruption of daily activities, social embarrassment, and physical exhaustion secondary to frequent coughing episodes.
Chronic Refractory Cough Diagnosis
CRC can be diagnosed when patients have no identified causes of CC or when the cough persists after investigation and treatment of cough-related conditions.
The diagnosis of the disease is either done by primary or secondary assessment. The initial assessment for protracted or chronic cough is intended to characterize the condition based on history, to elicit any alarm symptoms or findings that may indicate a serious underlying disease, and to identify whether there is a specific disease present that is associated with CC.
The first step in evaluating individuals with CRC is performing a correct and complete anamnesis, followed by a physical examination. While the second stage of investigation is considered to further characterize the condition of the disease. These include nasendoscopy and 24-hour pH monitoring. Laryngeal examination using flexible nasendoscopy identifies the presence of laryngeal lesions or abnormal motor patterns that might be contributing to the cough symptoms and laryngeal discomfort.
Some of the common tests that are performed to examine chronic cough are chest radiograph, spirometric and peak expiratory flow measurements, bronchoprovocation testing, sinus imaging, etc.

Chronic Refractory Cough Treatment
According to the recent guidelines published by the American College of Chest Physicians (ACCP) four categories of treatment can be implemented which include nonpharmacologic therapies, ICS, neuromodulatory therapies, proton pump inhibitors, and other therapies.
The market for CRC is mainly dominated by nonpharmacologic therapies, which include Speech Therapy and Physiotherapy. The first step in Speech Pathology Management of CRC patients is to evaluate the pathophysiological features of the condition, including cough characteristics, urge to cough, Paradoxical vocal fold movement (PVFM), and voice symptoms.
After nonpharmacological therapies, the market holds various types of pharmacologic therapies which include neuromodulators, proton pump inhibitors, ICS, and other treatment options. Neuromodulators include opiates (morphine, codeine, tramadol, etc.), gabapentin, pregabalin, morphine, amitriptyline, and baclofen, which act on the heightened neural sensitization that is involved in the pathogenesis of CRC. Combined therapy can also be employed to treat patients with CRC. This includes the use of nonpharmacologic and pharmacologic interventions together.
Recently in 2022, Japan's MHLW approved Merck's LYNFUA (gefapixant), an orally-administered, selective P2X3 receptor antagonist for the treatment of adults with RCC or UCC.

Chronic Refractory Cough Market Outlook
CRC proves to be a huge burden on the patients who are fighting this debilitating condition. It is typically nonproductive and there is often a preceding history of viral respiratory tract infection. Patients frequently describe a dry, irritating cough that may be localized to the laryngeal region. It significantly impairs patients' quality of life. Unfortunately, in many situations, patients continue to experience CRC despite following the published guidelines for diagnosis and treatment.
Currently, the market holds no approved therapy to treat CRC. According to the recent guidelines published by the American College of Chest Physicians (ACCP) four categories of treatment can be implemented which include nonpharmacologic therapies, ICS, neuromodulatory therapies, proton pump inhibitors, and other therapies.
The market for CRC is mainly dominated by nonpharmacologic therapies, which include Speech Therapy and Physiotherapy. The main strategies that are followed by the speech therapists include education (Cough can be triggered by irritation, controlling the urge to cough, etc.), symptom control techniques, such as cough suppression swallow, cough control breathing, PVFM release breathing, and release of laryngeal restriction, reduction in laryngeal irritation (behavioral management of reflux, reduction in phonotraumatic behaviors, patients should remain hydrated and minimizing exposure to the irritating substances.
After nonpharmacological therapies, the market holds various types of pharmacologic therapies which include neuromodulators, proton pump inhibitors, ICS, and other treatment options. Neuromodulators include opiates (morphine, codeine, tramadol, etc.), gabapentin, pregabalin, morphine, amitriptyline, and baclofen, which act on the heightened neural sensitization that is involved in the pathogenesis of CRC.
ICS are effective in eosinophilic airway inflammation. An assessment of airway eosinophilia (induced sputum, bronchoalveolar lavage) or exhaled NO is followed before subjecting patients with ICS in case of CRC. These mainly include mometasone, budesonide, and beclometasone. Treatment with ICS can significantly reduce cough but regress analyses are required to address the exact treatment regimen of these drugs.
Combined therapy can also be employed to treat patients with CRC. This includes the use of nonpharmacologic and pharmacologic interventions together, i.e., combining speech therapy with drugs to provide relief to the patients. Patients on speech therapy can be advised to opt for drugs, such as pregabalin or gabapentin. Recently Japan's MHLW approved Merck's LYNFUA (gefapixant), an orally-administered, selective P2X3 receptor antagonist for the treatment of adults with RCC or UCC
The market holds a critical unmet need with no approved curative definitive therapy for CRC. The pharmacologic therapies that are employed cannot be used in a long term due to various adverse events associated with them. Expected launch of potential therapies that include orvepitant maleate (Nerre Therapeutics), BLU-5937 (Bellus Health), MK-7264 (gefapixant) (Merck), AX-8 (Axalbion), S-600918 (Shionogi), and NP-120 (ifenprodil) (Algernon Pharmaceuticals) may address this unmet need, increase the market size in the coming years, assisted by an increase in the diagnosed prevalent population of CRC during the forecast period [2022-2032].
According to DelveInsight, the overall dynamics of the CRC market is anticipated to change in the coming years owing to the expected launch of emerging therapies.
