Active clinical trials for "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.

The purpose of this study is to evaluate the antitussive (cough-suppressing) effects of two liquid medications: a combination of diphenhydramine and phenylephrine in a naturally cocoa flavoring, and, dextromethorphan syrup, compared with placebo.

Post operative sore throat (POST) following tracheal intubation is a common problem causing dissatisfaction and discomfort to the patients. Prophylactic use of both lidocaine and dexamethasone has been used independently for this purpose. However, there is no study assessing the synergistic analgesic effects of lidocaine and dexamethasone for POST. The purpose of this study is to compare the effect of lidocaine, dexamethasone and lidocaine dexamethasone combination on the incidence and severity of POST.

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.

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.
