Active clinical trials for "Cough"

This study is designed to improve knowledge regarding the initial effectiveness of N-acetylcysteine (NAC) on cold and cough symptoms.

A randomized, double-blind, placebo-controlled, crossover, dose escalation study to assess the efficacy and tolerability of gefapixant (AF-219; MK-7264) in participants with refractory chronic cough.

Cough is a frequent symptom in children and infants and is one of the most common reasons parents visit a healthcare provider for their child. The US Food and Drug Administration has issued a warning that over-the-counter cough and cold medicines including antihistamines, decongestants, anti-tussives, and expectorants should not be administered to children younger than 2 years of age due not only to lack of proven efficacy, but also because of important safety concerns. Honey, another method of soothing cough cannot be used in children <1 year due to concerns for infantile botulism. A preparation from agave syrup has been created to address the need for an infant cough syrup. Although no studies have formally evaluated the use of agave nectar for nocturnal cough associated with Upper Respiratory Infections, the demulcent effect and sweet taste of agave nectar may provide some relief from cough in children.

Efficacy of proton pump inhibitor for chronic cough caused by gastroesophageal reflux; double-blind, placebo-controlled, randomized clinical trial

Idiopathic pulmonary fibrosis (IPF) is a devastating disease with no cure available. Patients suffer from respiratory symptoms including dyspnea and cough. To improve life quality the investigators will test the effects of immunomodulation of macrolides specifically on cough in IPF patients. The investigators hypothesize that immunomodulatory treatment reduces cough frequency and might improve lung function.

This is a study of the sodium channel inhibitor, GSK2339345. Cohort 1 will assess the safety, tolerability and PK of single ascending doses of GSK2339345 administered via an aqueous droplet inhaler in healthy subjects. Cohort 2 will assess the safety, tolerability, and PK of repeat doses of GSK2339345 administered four times a day for two consecutive days via an aqueous droplet inhaler.

The purpose of this study is evaluate if efficacy of a combination dose of oxomemazine, guaifenesin and potassium iodate is superior than guaifenesin monotherapy in acute cough treatment.

Montelukast, a leukotriene receptor antagonist, is likely to be effective in the treatment of chronic cough and this could be made objective by measuring cough threshold before and after two weeks of treatment.

The purpose of this study is to demonstrate the efficacy of azithromycin to produce a significant change in the cough-related health status, measured with the Dutch version of the Leicester Cough Questionnaire in patiënts with COPD gold classification 2-4 and chronic productive coughing.

The primary objectives of this study: To investigate the safety and tolerability of ascending repeated oral doses of BAY1902607 in healthy subjects (Part 1). To investigate the effect of BAY1902607 on the pharmacokinetics (PK) of a sub-therapeutic 1 mg dose of midazolam (Part 1). To investigate the safety, tolerability and efficacy of BAY1902607 in patients with refractory chronic cough (Part 2).
