Acute Cough—Does Anything Help?

The first thing your doctor should do is determine what is causing you to cough. Once your doctor determines what is causing the cough, he or she can treat the cause rather than the cough itself.

Has your cough has changed over time? Are you losing weight without trying? Are you coughing up phlegm? Do you have a fever? Do you currently smoke? Did you smoke in the past?

If you answered yes, to any of these questions, you should talk to your doctor about your cough. Your doctor may also give you a few tests including: A chest X-ray to take a picture of your lungs.

Summary In this article, we review the current clinical thinking regarding cough and the treatments that are currently used and those undergoing clinical development. Introduction Under normal physiological circumstances, coughing occurs with the primary purpose of protecting the lung from inhaled irritants and clearing unwanted airway secretions.

TRP Channels Transient receptor potential TRP channels were first discovered and described in Drosophila in the s but have since become important targets in chronic cough [ 15 ]. TRPM8 is activated by cooling compounds such as menthol, icilin and eucalyptol.

What is an acute cough?

Although thought to play a role in cough induced by the inhalation of cold air, the TRPM8 agonist menthol also has protective and soothing effects and is a component of many over-the-counter cough remedies [ 29 , 30 ]. The evidence for an antitussive role of TRPM8 is inconclusive and modulation of TRPM8 remains to be investigated as a potential target for chronic cough.

GABA-Related Compounds Gabapentin, Pregabalin Gabapentin and pregabalin are centrally acting neuromodulators primarily used for the treatment of neuropathic pain and epilepsy [ 55 ]. N-Methyl-D-Aspartate NMDA Receptors N-methyl-D-aspartate NMDA receptors are expressed within the peripheral and central nervous system and are believed to play a role in the synaptic transmission of cough-associated vagal afferents which project from the lungs to the brainstem [ 61 ]. Amitriptyline Amitriptyline is used for the treatment of depression and lower doses are also prescribed for the treatment of chronic neuropathic pain.

Tachykinin Receptor Antagonists The tachykinins, substance P, neurokinin A and neurokinin B are released both from the peripheral endings of afferent nerves predominately C-fibres and from central neural structures. The tachykinin receptor, neurokinin 1 receptor has gained attention as a target for chronic cough treatment. The NK1R antagonist, aprepitant, has been shown to reduce cough in patients with lung cancer [ 70 ]. A pilot study of serlopitant, a centrally acting NK1R antagonist, resulted in significant improvements in objective cough frequency and sustained reductions in daytime cough frequency [ 71 ].

Currently, serlopitant is undergoing further clinical evaluation Table 1. Orvepitant, another NK1 receptor antagonist, is also in phase 2 clinical trials Table 1.
