Active clinical trials for "Cough"

The primary objective of this study was to assess the effect of a single dose of gefapixant 100 mg on cough reflex sensitivity to various challenge agents (capsaicin, citric acid, adenosine triphosphate [ATP], and distilled water) in healthy and chronic cough participants.

The purpose of this study is to determine the effectiveness of XEN-D0501 over placebo in reducing the daytime cough frequency in patients with chronic idiopathic cough. The effectiveness of XEN-D0501 over placebo in reducing capsaicin cough responses, objective 24-hour cough frequency, hourly change in cough frequency, cough severity (via visual analogue scale [VAS]), urge to cough (via VAS), global rating of change scale and Leicester Cough Questionnaire (LCQ) will be evaluated.

After nasal surgery, emergence cough or straining will produce venous engorgement and increase bleeding from the surgical site, so the necessity for smooth extubation without severe cough during emergence provides a challenge for the anesthetists. Recently, remifentanil is commonly used short-acting opioid, and several studies have demonstrated the antitussive effect of remifentanil via effect-site target-controlled infusion during emergence. However, there may be gender difference in response to opioid, and the previous studies about antitussive effect of remifentanil are targeted at female patients and there is no investigation of effect site concentration of remifentanil for male patients undergoing nasal surgery. The purpose of this study is to evaluate the effect-site concentration of remifentanil via target-controlled infusion for preventing cough in man after sevofluorane balanced anesthesia.

Evaluation of Wire Electrodes to Activate the Expiratory Muscles to Restore Cough

This is a randomized, double-blind, placebo-controlled, crossover, single center study of SCH 486757 in subjects with chronic cough. Subjects will be randomized to receive SCH 486757 or placebo for 14 days. After a 2-week washout period, subjects will be crossed over to the other treatment. The primary objective is to evaluate the effectiveness of SCH 486757 in reducing cough reflex sensitivity as determined by a challenge with capsaicin, an agent that induces cough.

Cough is the most common reason for an acute care doctor's visit in the United States. Cough can affect sleep for both coughing children and their parents. The American Academy of Pediatrics does not endorse the use of dextromethorphan (DM), the most common over-the-counter (OTC) cough medication because of a lack of efficacy data and some potential for toxicity, particularly when taken in excess. In fact, DM has previously been shown to be no better than a placebo for cough in children. Therefore, alternative, therapeutic agents are needed. Honey anecdotally provides relief for symptoms due to upper respiratory tract infection (URI). This study seeks to use a survey to evaluate whether a single dose of honey and/or DM is better than no treatment at all for controlling nocturnal cough in children with URI and the effect of the treatments on sleep quality for coughing children and their parents. A single dose of honey or DM will be superior to no treatment for control of nocturnal cough due to upper URI as rated by both parents and children and will improve the sleep quality for those children and parents. Compared to DM, honey will be superior for controlling nocturnal cough due to upper URI (also based on child and parental report).

The primary objective of this study is to determine the optimal dose of S-600918 in patients with refractory chronic cough by evaluating the change from baseline in 24-hour cough frequency (coughs per hour) with S-600918 compared with placebo.

Chronic cough is more frequent and severe in women than in men. Women often have decreased iron stores, due to menses and pregnancies. Aim of the study: to investigate if iron deficiency has a role in chronic cough by favouring airway hypersensitivity to inhaled irritants.

A randomized, double-blind, placebo-controlled, crossover, dose escalation study of gefapixant (AF-219) in participants with Idiopathic Pulmonary Fibrosis (IPF) with persistent cough.

The present clinical trial will examine the use of ABO/MEG-B-09 syrup in children with acute cough as compared to a placebo syrup.
