BACKGROUND Capsaicin, the pungent extract of red peppers, has achieved widespread use in clinical research because it induces cough in a dose-dependent and reproducible manner. Although > 2 decades of experience has led investigators to consider capsaicin cough challenge testing a safe diagnostic modality, this issue has not been specifically addressed in the literature. STUDY OBJECTIVES To review the published experience with capsaicin inhalation challenge testing in terms of safety…

Review: Effect of drugs on human cough reflex sensitivity to inhaled capsaicin

The current review summarizes the published experience with capsaicin inhalation challenge in the evaluation of drug effects on cough reflex sensitivity and suggests that subjects with pathological cough comprise the optimal group in which to evaluate the effect of potential antitussive agents on human cough Reflex sensitivity.

Capsaicin sensitivity in patients with chronic cough– results from a cross-sectional study

The current findings confirm that this sensitivity is related to enhanced capsaicin cough sensitivity and indicates more involvement of airway sensory nerves in the pathophysiology of the disease than in cough without evident trigger factors.

Laboratory Safety of Capsaicin Inhalation in Healthy Younger and Older Populations Potential Template for Inhalation Research

The investigation champions the opinion that inhalation studies involving FDA non-approved drugs or chemicals/ medications can be safely conducted when following the appropriate safety procedures such as in this research protocol.

Altering cough reflex sensitivity with aerosolized capsaicin paired with behavioral cough suppression: a proof-of-concept study.

This study demonstrates the potential of treating patients with refractory chronic cough, due to cough hypersensitivity, with a progressive desensitization approach paired with behavioral cough suppression, across repeated treatment sessions.

Cough reflex induced by capsaicin inhalation in patients with dysphagia

It is concluded that the capsaicin inhalation test is useful to directly assess cough reflex and sensation around the larynx, while it indirectly reflects central nervous system function.



Cough reflex testing with inhaled capsaicin in the study of chronic cough.

Cough sensitivity to inhaled capsaicin is a safe and reproducible tool in the study of chronic cough, however, its usefulness for the management and differential diagnosis is limited.

Capsaicin-induced cough in humans.

Capsaicin-induced cough is characterized and it is demonstrated that it can be a useful tool in the study of cough reactivity and for evaluation of antitussive agents in humans.

Increased Capsaicin Cough Sensitivity in Patients with Multiple Chemical Sensitivity

It is concluded that airway sensory reactivity is increased in patients with MCS, a finding which suggests that neurogenic factors may be of importance in this condition.

Capsaicin cough sensitivity is decreased in smokers.

Results are in agreement with the hypothesis that nicotine inhibits or blocks C-fibres of the sensory nervous system of the lower respiratory tract, which may serve to explain increasing airway symptoms that are often seen after cessation of smoking.

Capsaicin inhalation test for identification of sensory hyperreactivity.

The capsaicin inhalation test well reflects the degree of airway sensitivity to chemicals and to what extent the social life is influenced and the cut-off values of the test can distinguish patients with pronounced sensitivity to odours.

Capsaicin cough receptor sensitivity test in children.

It is concluded that in children, the capsaicin cough challenge test is well-tolerated; the inspiratory flow significantly influences cough receptor sensitivity and repeatability of the test and should, thus, be regulated.

Tachyphylaxis to capsaicin-induced cough and its reversal by indomethacin, in patients with the sinobronchial syndrome

It is suggested that cyclooxygenase products released by the airway inflammation may be involved in tachyphylaxis, cough receptor sensitivity to inhaled capsaicin, or both, in patients with the SBS.

Tussive effect of capsaicin in patients with gastroesophageal reflux without cough.

All patients with a pathologic acid exposure time but one had a low cough threshold, irrespective of the presence or absence of esophagitis, in patients with digestive symptoms but free from respiratory involvement.
