Filter by:This study attempts to document the therapeutic value of combining loratadine antihistamine action (no sedative) with anti-inflammatory effects of betamethasone at low doses, which may facilitate treatment adherence by patients whereas providing an effective and rapid perennial allergic rhinitis (PAR) symptoms relief.
This is a 6-month multi-center, randomized, double-blind, placebo-controlled, parallel group, efficacy and safety study of ciclesonide HFA nasal aerosol administered once-daily to male and female subjects 12 years or older diagnosed with perennial allergic rhinitis (PAR).
The purpose of this study is to noninvasively measure the anti-inflammatory effect of levocetirizine after two weeks of treatment in allergic rhinitis subjects.
This is a single-centre, randomised, double-blind, four-period, incomplete block, crossover study, with 8 days repeat dosing of intranasal Fluticasone Propionate (25, 50, 100, 200ug) and/or placebo in the Vienna Challenge Chamber in subjects with allergic rhinitis.
The purposes of this pilot safety study are to identify a dose of inhaled Clinical Center Reference Endotoxin (CCRE) that is well tolerated by allergic subjects that induces measurable increases in neutrophil content of induced sputum that can be employed to screen large populations for susceptibility to the inflammatory effect of inhaled endotoxin.
There is currently no effective way to prevent development of allergic rhinitis (nasal allergies) and asthma and no cure. Sublingual immunotherapy (SLIT), a type of therapy in which allergens are placed under the tongue, may be a way to control and possibly prevent allergic rhinitis and asthma. However, detailed research of this approach is limited. The purpose of this study is to evaluate the safety and efficacy of a sublingual cockroach extract given to adults with perennial allergic rhinitis, asthma, or both.
A total of 41 adults with perennial allergic rhinitis were enrolled in a first double-blind placebo-controlled phase for six months, and treated on a weekly basis with sublingual doses of single individualized homeopathic medicines or placebo. After this closed initial phase, all patients were invited to participate in an long-term open-label controlled phase, in that they would receive homeopathic treatment for the maximum period of 36 months, and the results were compared with the improvement of initial phase. Signs and symptoms scores, rescue medication requirements and quality of life were assessed by questionnaires and personal clinical evaluation by a same independent researcher, before and after each phase. Primary and secondary clinical outcome were, respectively, specific and general allergic signs and symptoms scores. Total IgE titles were performed before and after each phase.
- The primary objective of this study is to evaluate the efficacy of the concomitant administration of ciclesonide nasal spray and azelastine nasal spray versus ciclesonide nasal spray alone in patients (18 years or older) with perennial allergic rhinitis (PAR) not adequately controlled on an intranasal corticosteroid or antihistamine monotherapy - The secondary objective is to investigate the safety of the concomitant administration of ciclesonide nasal spray and azelastine nasal spray
This was a crossover study designed to see if patients with allergy symptoms preferred Clarinex® or Zyrtec®. Patients were randomized to take 7 days of Clarinex or Zyrtec treatment, followed by a 5 to 28-day washout period (days when no drug is given), followed by 7 days of the opposite treatment. At the end of each 7-day treatment, patients were asked questions to determine which drug, Clarinex or Zyrtec, the patient prefers more.
