Active clinical trials for "Cough"

This study was conducted to investigate the effect of the LVR technique on cough ineffectiveness, to determine its benefit as a simple, safe, and inexpensive cough augmentation technique, and to determine how much the LVR method, for augmenting CPF, is useful in enhancing the success of extubation and reducing the rate of reintubation.

The primary objective of this double-blind crossover study is to assess the effect of single doses of 50 mg and 300 mg gefapixant (AF-219/MK-7264) on cough reflex sensitivity to capsaicin in both healthy participants and participants with chronic cough. This study will also assess the effect of single doses of gefapixant on cough reflex sensitivity to adenosine triphosphate (ATP) in healthy participants and participants with chronic cough.

ABSTRACT: The aim of this study was to investigate the effect of betamethasone gel and lidocaine jelly (over tracheal tube cuff) compared with distilled water on the post intubation syndrome incidence. This study has not been carried out in Iran. 99 patients of either sex undergoing elective surgery were recruited in a single blind randomized study. The patients, using randomization table, were divided into three groups. Anesthetics and medications used during surgery were similar for all the patients. For the all patients, the incidence of postoperative sore throat, cough and hoarseness of the voice in the different follow-up periods (1, 6 and 24 hours) based on the different types of medications were obtained.

This is a First Time in Human (FTIH) study for the sodium channel inhibitor, GSK2339345. The study is split into two parts. Part A will assess the safety and tolerability of the new drug. Part B will assess safety and tolerability as well as the effect of GSK2339345 on induced cough.

The purpose of this study is to determine the antitussive effect size and dose response of FP01 lozenges in subjects with chronic cough and to demonstrate the safety and tolerability of FP01 lozenges in subjects with chronic cough.

The purpose of this research study is to learn how effective and safe FP01 lozenges are when given to subjects with a cough due to an upper respiratory tract infection. The study will include subjects who have an upper respiratory tract infection, with a cough of less than six weeks duration.

The pharmacological effects of PDC-748 were tested in numerous in vitro and in vivo studies. The existing pharmacologic findings suggest that PDC-748 possesses certain inhibitory activity to the citric acid- and capsaicin-induced cough reflex in guinea pigs with a dose-dependent manner. Furthermore, a previous Phase I/II uncontrolled, dose-escalating study has shown PDC-748 to be well tolerated and may help to alleviate daytime cough with a dose-responding manner.Hence, PhytoHealth Corporation intends to carry out a Phase II investigation to confirm the preliminary findings using placebo in the comparator group, and to further investigate PDC-748 with a dose escalating manner to establish the dose-response range for its antitussive effect, and if possible, to determine the maximal tolerable dose of PDC-748. This is a randomized, double-blind, placebo-controlled, dose escalating study to evaluate the safety and efficacy of the escalating dose levels of PDC-748 in patients with acute cough.

Idiopathic Pulmonary Fibrosis (IPF) is a rapidly progressive lung disorder that is often associated with a chronic, intractable cough. The etiology of the cough associated with IPF is unclear but it is often so severe that it adversely effects the patient's quality of life. We propose that thalidomide specifically suppresses the cough associated with idiopathic pulmonary fibrosis via its anti-inflammatory properties, by suppressing the excessive functional up-regulation of sensory fibers with in the respiratory tract of patients with IPF. This study is a Phase III, double blinded, randomized, placebo controlled, crossover trial testing the efficacy of thalidomide in suppressing the chronic cough of IPF. The primary objective of this study is to determine the efficacy of thalidomide administered daily for 12 weeks to suppress the chronic cough in patients with idiopathic pulmonary fibrosis as measured by cough specific questionnaires, scales and improved quality of life.

This randomized, multicenter, parallel-group, double-blind, double-dummy, placebo- and active-controlled study will evaluate the efficacy and safety of SCH 486757 in subjects with persistent cough resulting from a recent viral upper respiratory infection (URI). The primary objective is to assess the efficacy of SCH 486757 administered at a dose of 100 mg twice daily for 5 days in the reduction of cough severity score compared with placebo. The key secondary objective is to evaluate the reduction in the number of coughs with SCH 486757 compared with placebo. Because codeine is a widely used as a cough medication, it is included as a treatment arm in the study.

Part 1 will evaluate the safety, tolerability and PK of single doses of three dose levels of NTX-1175 drug substance administered by dry powder inhaler (NOC-110) compared to a single dose reference nebulizer (NOC-100) treatment in healthy participants. Part 2 will evaluate the safety, tolerability and PK of multiple doses of NTX-1175 drug substance administered by dry powder inhaler (NOC-110) to participants with refractory chronic cough. Part 2 will also evaluate the treatment effect of multiple doses of one dose level of NTX-1175 drug substance administered by dry powder inhaler (NOC-110).
