Filter by:Multicenter clinical trial, phase III, controlled by active medicine, double-blind, randomized, enroll 208 subjects, above 12 years old, that suffer acute inflammation upper airway characterized by non-productive cough, daytime/nighttime, with duration for at least 3 and no more than 5 consecutive days (without systemic/topic use of medication during this period) followed by nasal congestion, with or without associate other nasal symptoms (sneezing, runny nose, nasal itching and/or mouth breathing). The subjects will be allocated in 2 parallel groups, and will receive the medicines of study, according of the randomization.
Multicenter clinical trial, phase III, controlled by active medicine, open, randomized, enroll 962 children, 2 to 12 years old, that suffer acute inflammation upper airway characterized by non-productive cough, daytime/nighttime, with duration for at least 3 and no more than 5 consecutive days (without systemic/topic use of medication during this period) followed by nasal congestion, with or without associate other nasal symptoms (sneezing, runny nose, nasal itching and/or mouth breathing). The subjects will be allocated in 2 parallel groups, and will receive the medicines of study, according of the randomization.
The primary objective of this study is to evaluate the clinical efficacy of the drug Cloratadd D ® (loratadine + pseudoephedrine sulfate - EMS S/A) compared to the drug Claritin D ® (loratadine + pseudoephedrine sulfate - Schering Plough) in patients with allergic rhinitis by quantification of the scores of clinical parameters (signs and symptoms) and laboratory (nasal flow) down through time.
Objectives: A) To gather pharmacodynamic measurements and assess blood levels of the active ingredients in AHIST over the dosage interval period of 12 hours. Hypothesis: Hysteresis curves plotting each active ingredient's blood levels over a 12-hour dosage interval will substantiate S5 Symptom Diary scores (IE: evidentiary therapeutic window data); B) To report subjective scores by subjects rating the efficacy of a single dose AHIST in relieving nasal congestion, rhinorrhea, nasal itching, sneezing, and post-nasal drip over a 12-hour dosage interval. Hypothesis: Greater than 66% of subjects will document clinically significant relief over a 12-hour period from one dose of AHIST; C) Report any side effects or adverse drug reactions and rate the severity of any incidence. Hypothesis: Not more than one patient will have an adverse event significant enough to warrant withdrawal; side effects will be mild with the most frequently reported side effect occurring in less than 10% of patients—drowsiness.
The purpose of this study is to measure the effects of allergens and/or diesel exhaust particles in the nose to learn more about allergic responses in individuals with cat allergic rhinitis.
The investigators wish to evaluate the effects of decongestants like oxymetazoline and the lessening of this effect with time called 'tolerance'. The investigators will demonstrate a reversal of this tolerance with nasal steroids i.e. the investigators will show that nasal steroids protect against tolerance. This will tell us more on how the investigators can make this treatment effective and safe for patients suffering with allergic rhinitis.
The purpose of this study is to see how a combination spray of azelastine and fluticasone (antihistamine and steroid) compares with a steroid nasal spray (fluticasone) alone in allergic rhinitis i.e. does azelastine permit the use of lesser steroid dose (steroid sparing effect) to achieve the same benefit.
The purpose of this study is to measure the amount of a nasal steroid spray (ciclesonide) absorbed by the tissue in the nose 2 hours after having this study drug sprayed in the nose
The four respiratory drugs being researched in this study have been approved by the US Food and Drug Administration (FDA) and are currently available by prescription at your drug store. One of the drugs is for the treatment of asthma alone, one is for treatment of SAR alone, and one is for treatment of both SAR and asthma. In addition, you will also receive one asthma rescue drug (albuterol) that is to be used for any breakthrough asthma symptoms that you may experience throughout the study. The purpose of this study is to see how well your asthma and SAR are controlled when taking one of the medicine combinations
