Filter by:This study is designed to evaluate the efficacy of three dose regimens of gefapixant ([MK-7264] 7.5 mg, 20 mg, and 50 mg) relative to placebo in reducing awake objective cough frequency. The primary hypothesis for this trial is that at least one dose regimen of gefapixant is superior to placebo with respect to the mean change from baseline in awake cough frequency (on the log scale).
The aim of this study is described as follows, 1. To establish a validated method to test cough reflex sensitivity conducted by transient receptor potential vanilloid 1(TRPV1). 2. To observe the variance of cough reflex sensitivity conducted by transient receptor potential ankyrin 1(TRPA1) of chronic patients and the relationship between cough reflex sensitivity conducted by TRPA1 and conducted by TRPV1. 3. To study the distribution of TRPA1 and TRPV1 channels and their relationship to cough reflex sensitivity.
This study evaluates the non-inferiority of Suppository Transpulmin and Suppository Guaiacol compared to Transpulmin Syrup in the treatment of cough with secretion of infectious origin in children between two and six years old. One third of participants will receive Suppository Transpulmin, the other one third will receive Suppository Guaiacol and the last one third will receive Transpulmin Syrup.
The objectives of this pivotal study are: 1. to evaluate bioavailability of an extended-release and immediate release Codeine Phosphate/Guaifenesin tablet at steady state following multiple oral administration 2. to assess the safety and tolerability of this Codeine Phosphate/Guaifenesin extended release formulation.
A randomized, double-blind, placebo-controlled, crossover, dose escalation study of gefapixant (AF-219) in participants with Idiopathic Pulmonary Fibrosis (IPF) with persistent cough.
This study aims to assess the presence and the intensity of voluntary and cough reflex in patients with amyotrophic lateral sclerosis (ALS), comparing the results with the healthy control group. The assessment of the cough is fundamental to verify the mechanism of airways protection which is particularly compromised in ALS patients. Objective parameters of voluntary and reflex cough would be measured by the spirometer. The reflex of cough would be elicited by a solution of citric acid through an ultrasonic nebulizer.
To determine whether contraction abnormalities in the esophagus plays a role in gastroesophageal reflux induced cough, and thus cough severity in patients with chronic cough.
Cough is a life saving reflex, therefore it is important, especially in pediatrics, to calm cough spells without sedating the reflex. The intent of this study is to use a protective syrup with does not act as a sedative or as a potent mucolytic and measure its efficacy and safety versus placebo in children with moderate to severe night and daily cough. Cough is assessed with a validated parent questionnaire. The degree of disturbance of cough is followed immediately after one night administration of the study products and daily for 4 nights, 3 days.
The purpose of this study is to determine if Pregabalin, a medication used for the treatment of seizures and chronic pain, can be used to effectively treat people who suffer from non-asthmatic chronic cough (cough lasting over 8 weeks).
In this study the investigators wish to explore the difference in 24 hr. cough counts measured using the Hull Automated Cough Counter (HACC), from baseline and after two weeks treatment with either montelukast or prednisolone in patients with an NO measurement of ≥30 ppb at screening.
