ABSTRACT
Background: Amongst the common problems facedglobally, Allergic Rhinitis (AR) is very distressing attimes. This is an inflammatory response to either knownor unknown allergen. The symptomatic relief in ARusing topical steroid Fluticasone propionate andantihistaminic Azelastine Hydrochloride in acombination has been studied. Very few studies showingcomparison between these two drugs in a combinationand steroid alone are available in the literature. Aim andObjectives: To study the effectiveness of topicaltreatment using corticosteroid Fluticasone propionateand antihistaminic in a combination versus Fluticasonepropionate alone in patients of AR. Material andMethods: The cases presented with symptoms ofallergic rhinitis were randomized in two groups at startof treatment. All cases of Group I were treated withFluticasone propionate whereas of Group II withFluticasone propionate and Azelastine hydrochloridecombination. In each group, the individual symptomscores were recorded pre-treatment and post-treatmentat the end of four weeks with the help of symptomevaluation scale. Based on these individual symptomscores, the Total Symptom Score (TSS) was calculated.The effectiveness of group specific drugs was evaluatedby comparing individual and TSS. Results: After fourweeks, both TSS and individual symptom score werereduced in either group (p<0.05). Further, Group IIspecific drug was found more effective than Group-I inrelieving symptoms of AR. Conclusion: TSS decreasedby an average of 84.14% in Group-I (i.e. treated withFluticasone propionate) and by 91.16% in Group–II (i.e.treated with Fluticasone propionate and Azelastinehydrochloride I in a combination).
ABSTRACT
OBJECTIVE To observe clinical efficacy of azelastine hydrochloride nasal spray plus budesonide nasal spray on persistent allergic rhinitiss(AR). METHODS 120 patients with persistent AR were devided randomly into group A(n=40), group B(n=40) and group C(n=40).

ABSTRACT
Aims: Stability indicating densitometry-TLC assay was established and validated for determination of azelastine hydrochloride (AZT) and emedastine difumarate (ETD) in the presence of their acid and oxidative degradants. Methodology: Forced degradation was performed using 30% H2O2 and 5 M HCl. The method was based on thin-layer chromatographic separation of the two drugs from their degradants, using methanol- 10% ammonia (9.5:0.5, v/v) as developing system, followed by densitometric measurements of the intact drug spots at 292 and 283 nm, for azelastine hydrochloride and emedastine difumarate respectively. Results: The linear range was 0.5 - 10.0 μg/spot, with mean recoveries of 100.09 ± 0.53% and 100.36 ± 0.40% for azelastine hydrochloride and emedastine difumarate respectively. Conclusion: The proposed method was successfully applied for the routine quality control analysis of both drugs in laboratory prepared mixtures and commercially available preparations. The degradation products were identified by IR and MS and the pathways were illustrated. The method was validated according to ICH.

ABSTRACT
Background & Objectives: Vasomotor rhinitis (VMR) is a chronic non-allergic rhinitis without the increased Ig E level and eosinophilia. Azelastine hydrochloride is a second generation anti-histamine medication with anti-inflammatory properties that inhibits the synthesis of inflammatory materials. There are reports that azelastine hydrochloride can be effective in the treatment of VMR. Therefore, this study examined the clinical efficacy of intranasal azelastine hydrochloride spray in comparison with placebo for the treatment of VMR. MATERIALS AND METHOD: This study was a prospective double blind randomized test. The subjects consisted of 84 VMR patients. Among them, 54 patients were treated with intranasal azelastine hydrochloride for 4 weeks and 30 patients with intranasal normal saline. Following the treatment, an analysis of the symptom score was performed in order to compare the treatment effects between the study group and the control group. RESULTS: In the study group, the symptom score was significantly improved in the areas of sneezing (1.38 to 0.72), rhinorrhea (1.57 to 0.76), nasal obstruction (1.76 to 1.01) and postnasal drip (1.43 to 0.65). In the control group, however, the symptom score was significantly improved in a single area of rhinorrhea (1.73 to 0.65). Patients in the study group, thus, displayed greater improvements in the areas of sneezing, rhinorrhea, nasal obasturction and postnasal drip comparative to the control group. Consequently, the study group patients were more satisfied with their quality of life than those of the control group. CONCLUSION: Azelastine chloride is a useful medicine for the treatment of VMR, especially in controlling sneezing, rhinorrhea, nasal obstruction and postnasal drip.

AIM: To evaluate the antihistamine effects of domestic azelastine hydrochloride. METHODS: Histamine increased skin vascular permeability and induced shock model in guinea pigs. In isolated guinea pig ileal rings, the contraction of smooth muscle induced by histamine was determined. RESULTS: Pretreament with azelastine hydrochloride( 0.05, 0.15,and 0.45 mg?kg -1,ig) significantly inhibited the increase in skin vascular permeability induced by histamine in a dose-dependent manner in guinea pigs. Pretreament with azelastine hydrochloride( 0.05, 0.1,and 0.2 mg?kg -1,ig)produced a significant improvement of shock, as shown by a decrease in reactivity degree, mortality and a prolongation of latency. In isolated guinea pig ileal rings, azelastine hydrochloride (10 -8,3?10 -8,10 -7,3? 10 -7 mol?L -1)significantly inhibited contraction of smooth muscle induced by histamine in a concentration-dependent manner and caused a parallel right shift of the dose-effect curve of histamine (pA 2= 8.55). CONCLUSION: Domestic azelastine hydrochloride shows significant the antihistamine effects.
