Pharmacological Treatments for Cough
Pharmacological approaches to cough treatment depend on the underlying cause. For coughs linked to respiratory infections, honey and menthol are commonly used, while antihistamines are recommended for coughs associated with allergic rhinitis. Asthma-related coughs may be treated with leukotriene or muscarinic receptor blockers, and morphine is sometimes used for coughs related to malignant diseases. For prolonged idiopathic cough, menthol, muscarinic receptor blockers, or dextromethorphan can be considered. However, codeine is generally not necessary, and non-drug approaches should always be considered before starting medication . In children and adolescents, drug therapy options include H1 receptor antagonists, mucolytics, expectorants, and drugs acting on the cough reflex, but evidence for their efficacy and safety is limited, and many coughs resolve without treatment .
Herbal and Traditional Medicine for Cough Relief
Herbal remedies are widely used for cough management. Medicinal herbs such as Primula veris, Thymus vulgaris (thyme), Althaea officinalis (marshmallow root), and Mentha piperita (peppermint) have expectorant, anti-inflammatory, antiviral, and antibacterial properties. These herbs are often consumed as teas or extracts and are used to supplement standard medical care for cough . East Asian traditional medicine, including herbal medicine and acupuncture, is frequently used for chronic cough, especially when conventional treatments are ineffective. Most studies report positive outcomes, but more high-quality research is needed to confirm their efficacy . Specific Chinese herbal preparations have also shown potential benefits for postinfectious cough .
Non-Pharmacological and Behavioral Cough Treatments
Non-pharmacological techniques play a significant role in cough management, especially for patients at the extremes of the cough spectrum. Cough augmentation techniques help those with weak coughs to clear airways, while cough control techniques—such as education, retraining, and psychological support—help those with frequent or sensitive coughs to suppress unnecessary coughing . Speech pathology-based cough suppression therapy has shown benefits for unexplained chronic cough, improving cough severity and quality of life . Behavioral cough suppression therapy combined with repeated exposure to capsaicin (a cough-inducing agent) has shown promise in reducing cough frequency in patients with refractory chronic cough, though more research is needed .
Acupuncture and Integrative Approaches
Acupuncture and related therapies, such as acupoint herbal patching and moxibustion, have been found to improve cough severity and quality of life when used alongside conventional treatments. These therapies appear to be safe and effective for chronic cough of various causes, with moderate certainty of evidence . Acupuncture is commonly used in East Asian traditional medicine for chronic cough, and studies generally report positive outcomes .
Algorithmic and Cause-Specific Approaches
A stepwise, algorithmic approach to chronic cough involves identifying and treating the underlying cause. The most common causes are postnasal drip syndrome (often from rhinitis), asthma, and gastroesophageal reflux. Initial treatment typically involves antihistamine-decongestants for postnasal drip, followed by asthma therapy if needed, and then evaluation and treatment for gastroesophageal reflux. This approach has been shown to resolve cough in most patients when the underlying cause is identified and treated appropriately .
Special Considerations for Unexplained Chronic Cough
For unexplained chronic cough (UCC), gabapentin is recommended as a treatment, while inhaled corticosteroids and esomeprazole are generally ineffective unless there are features of acid reflux. Speech pathology-based cough suppression is also suggested as a treatment option for UCC .
Conclusion
Cough treatment methods are diverse and should be tailored to the underlying cause and patient needs. Options include pharmacological agents, herbal and traditional remedies, non-pharmacological techniques, behavioral therapies, and integrative approaches like acupuncture. While many treatments show promise, especially for chronic or unexplained cough, more high-quality research is needed to confirm their efficacy and safety across different patient populations Ozdemir2024Spinou2018Archa2023+7 MORE.
