What's The Definition Of The Medical Condition Azelastine Nasal Spray?Clinical Pharmacology CLINICAL PHARMACOLOGY Mechanism Of Action Azelastine hydrochloride, a phthalazinone derivative, exhibits histamine H1 -receptor antagonist activity in isolated tissues, animal models, and humans.
Azelastine HCl nasal solution (nasal spray) is administered as a racemic mixture with no difference in pharmacologic activity noted between the enantiomers in in vitro studies.
The major metabolite, desmethylazelastine, also possesses H1 -receptor antagonist activity.
Pharmacodynamics Cardiac Effects In a placebo-controlled trial (95 patients with allergic rhinitis), there was no evidence of an effect of azelastine hydrochloride nasal spray (2 sprays per nostril twice daily for 56 days) on cardiac repolarization as represented by the corrected QT interval (QTc) of the electrocardiogram.
Following multiple dose oral administration of azelastine 4 mg or 8 mg twice daily, the mean change in QTc was 7.2 msec and 3.6 msec, respectively.
Interaction studies investigating the cardiac repolarization effects of concomitantly administered oral azelastine hydrochloride and erythromycin or ketoconazole were conducted.
Oral erythromycin had no effect on azelastine pharmacokinetics or QTc based on analysis of serial electrocardiograms.
Ketoconazole interfered with the measurement of azelastine plasma levels; however, no effects on QTc were observed [see DRUG INTERACTIONS].
Pharmacokinetics Absorption After intranasal administration of 2 sprays per nostril (548 mcg total dose) of azelastine HCl nasal solution (nasal spray), 0.1%, the mean azelastine peak plasma concentration (Cmax) is 200 pg/mL, the mean extent of systemic exposure (AUC) is 5122 pg•hr/mL and the median time to reach Cmax (tmax is 3 hours.
After intranasal administration of 2 sprays per nostril (822 mcg total dose) of azelastine HCl nasal solution (nasal spray), 0.15%, the mean azelastine peak plasma concentration (Cmax) is 409 pg/mL, the mean extent of systemic exposure (AUC) is 9312 pg•hr/mL and the median time to reach Cmax (tmax ) is 4 hours.
The systemic bioavailability of azelastine hydrochloride is approximately 40% after intranasal administration.
Distribution Based on intravenous and oral administration, the steady-state volume of distribution of azelastine is 14.5 L/kg.
In vitro studies with human plasma indicate that the plasma protein binding of azelastine and its metabolite, desmethylazelastine, are approximately 88% and 97%, respectively.
Metabolism Azelastine is oxidatively metabolized to the principal active metabolite, desmethylazelastine, by the cytochrome P450 enzyme system.
The specific P450 isoforms responsible for the biotransformation of azelastine have not been identified.
After a single-dose, intranasal administration of azelastine HCl nasal solution (nasal spray), 0.1% (548 mcg total dose), the mean desmethylazelastine Cmax is 23 pg/mL, the AUC is 2131 pg•hr/mL and the median tmax is 24 hours.
After a single-dose, intranasal administration of azelastine HCl nasal solution (nasal spray), 0.15% (822 mcg total dose), the mean desmethylazelastine Cmax is 38 pg/mL, the AUC is 3824 pg•hr/mL and the median tmax is 24 hours.
After intranasal dosing of azelastine to steady-state, plasma concentrations of desmethylazelastine range from 20-50% of azelastine concentrations.
Elimination Following intranasal administration of azelastine HCl nasal solution (nasal spray), 0.1%, the elimination half-life of azelastine is 22 hours while that of desmethylazelastine is 52 hours.
Following intranasal administration of azelastine HCl nasal solution (nasal spray), 0.15%, the elimination half-life of azelastine is 25 hours while that of desmethylazelastine is 57 hours.
Approximately 75% of an oral dose of radiolabeled azelastine hydrochloride was excreted in the feces with less than 10% as unchanged azelastine.
Special Populations Hepatic Impairment Following oral administration, pharmacokinetic parameters were not influenced by hepatic impairment.
Renal Impairment Based on oral, single-dose studies, renal insufficiency (creatinine clearance <50 mL/min) resulted in a 70-75% higher Cmax and AUC compared to healthy subjects.
Time to maximum concentration was unchanged.
Age Following oral administration, pharmacokinetic parameters were not influenced by age.
Gender Following oral administration, pharmacokinetic parameters were not influenced by gender.
Race The effect of race has not been evaluated.
Drug-Drug Interactions Erythromycin Co-administration of orally administered azelastine (4 mg twice daily) with erythromycin (500 mg three times daily for 7 days) resulted in Cmax of 5.36 ± 2.6 ng/mL and AUC of 49.7 ± 24 ng•h/mL for azelastine, whereas, administration of azelastine alone resulted in Cmax of 5.57 ± 2.7 ng/mL and AUC of 48.4 ± 24 ng•h/mL for azelastine [see DRUG INTERACTIONS].
Cimetidine And Ranitidine In a multiple-dose, steady-state drug interaction trial in healthy subjects, cimetidine (400 mg twice daily) increased orally administered mean azelastine (4 mg twice daily) concentrations by approximately 65%.
Co-administration of orally administered azelastine (4 mg twice daily) with ranitidine hydrochloride (150 mg twice daily) resulted in Cmax of 8.89 ±3.28 ng/mL and AUC of 88.22 ± 40.43 ng•h/mL for azelastine, whereas, administration of azelastine alone resulted in Cmax of 7.83 ± 4.06 ng/mL and AUC of 80.09 ± 43.55 ng•h/mL for azelastine [see DRUG INTERACTIONS].
Theophylline No significant pharmacokinetic interaction was observed with the co-administration of an oral 4 mg dose of azelastine hydrochloride twice daily and theophylline 300 mg or 400 mg twice daily.
Clinical Studies Seasonal Allergic Rhinitis AzelastineHCl Nasal Solution (Nasal Spray), 0.1% The efficacy and safety of azelastine HCl nasal solution (nasal spray), 0.1% was evaluated in a 2-week, randomized, multicenter, double-blind, placebo-controlled clinical trial including 834 adult and adolescent patients 12 years of age and older with symptoms of seasonal allergic rhinitis.
The population was 12 to 83 years of age (60% female, 40% male; 69% white, 16% black, 12% Hispanic, 2% Asian, 1% other).
Patients were randomized to one of six treatment groups: 1 spray per nostril of either azelastine HCl nasal solution (nasal spray), 0.1%, azelastine HCl nasal solution (nasal spray) without sweetener or vehicle placebo twice daily; or 2 sprays per nostril of azelastine HCl nasal solution (nasal spray), 0.1%, azelastine HCl nasal solution (nasal spray) without sweetener or vehicle placebo twice daily.
Assessment of efficacy was based on the 12-hour reflective total nasal symptom score (rTNSS) assessed daily in the morning and evening, in addition to the instantaneous total nasal symptom score (iTNSS) and other supportive secondary efficacy variables.
TNSS is calculated as the sum of the patients’ scoring of the four individual nasal symptoms (rhinorrhea, nasal congestion, sneezing, and nasal itching) on a 0 to 3 categorical severity scale (0 = absent, 1 = mild, 2 = moderate, 3 = severe).
The rTNSS required patients to record symptom severity over the previous 12 hours.
For the primary efficacy endpoint, the mean change from baseline rTNSS, morning (AM) and evening (PM) rTNSS scores were summed for each day (maximum score of 24) and then averaged over the 2 weeks.
The iTNSS, recorded immediately prior to the next dose, were assessed as an indication of whether the effect was maintained over the dosing interval.
In this trial, azelastine HCl nasal solution (nasal spray), 0.1% two sprays twice a day demonstrated a greater decrease in rTNSS and iTNSS than placebo and the difference was statistically significant.
The trial results are presented in Table 3 (Trial 1).
The efficacy of azelastine HCl nasal solution (nasal spray), 0.1% one spray per nostril twice daily for seasonal allergic rhinitis is supported by two, 2-week, placebo-controlled clinical trials with azelastine HCl nasal solution (nasal spray) without sweetener in 413 patients with seasonal allergic rhinitis.
In these trials, efficacy was assessed using the TNSS (described above).
Azelastine HCl nasal solution (nasal spray) without sweetener demonstrated a greater decrease from baseline in the summed AM and PM rTNSS compared with placebo and the difference was statistically significant.
AzelastineHCl Nasal Solution (Nasal Spray), 0.15% The efficacy and safety of azelastine HCl nasal solution (nasal spray), 0.15% in seasonal allergic rhinitis was evaluated in five randomized, multicenter, double-blind, placebo-controlled clinical trials in 2499 adult and adolescent patients 12 years and older with symptoms of seasonal allergic rhinitis (Trials 2, 3, 4, 5, and 6).
The population of the trials was 12 to 83 years of age (64% female, 36% male; 81% white, 12% black, <2% Asian, 5% other; 23% Hispanic, 77% non-Hispanic).
Assessment of efficacy was based on the rTNSS, iTNSS as described above, and other supportive secondary efficacy variables.
The primary efficacy endpoint was the mean change from baseline in rTNSS over 2 weeks.
Two 2-week seasonal allergic rhinitis trials evaluated the efficacy of azelastine HCl nasal solution (nasal spray), 0.15% dosed at 2 sprays twice daily.
The first trial (Trial 2) compared the efficacy of azelastine HCl nasal solution (nasal spray), 0.15% and azelastine HCl nasal solution (nasal spray) without sweetener to vehicle placebo.
The other trial (Trial 3) compared the efficacy of azelastine HCl nasal solution (nasal spray), 0.15% and azelastine HCl nasal solution (nasal spray), 0.1% to vehicle placebo.
In these two trials, azelastine HCl nasal solution (nasal spray), 0.15% demonstrated greater decreases in rTNSS than placebo and the differences were statistically significant (Table 3).
Three 2-week seasonal allergic rhinitis trials evaluated the efficacy of azelastine HCl nasal solution (nasal spray), 0.15% dosed at 2 sprays once daily compared to the vehicle placebo.
Trial 4 demonstrated a greater decrease in rTNSS than placebo and the difference was statistically significant (Table 3).
Trial 5 and Trial 6 were conducted in patients with Texas mountain cedar allergy.
In Trial 5 and Trial 6, azelastine HCl nasal solution (nasal spray), 0.15% demonstrated a greater decrease in rTNSS than placebo and the differences were statistically significant (Trials 5 and 6; Table 3).
Instantaneous TNSS results for the once daily dosing regimen of azelastine HCl nasal solution (nasal spray), 0.15% are shown in Table 4.
In Trials 5 and 6, azelastine HCl nasal solution (nasal spray), 0.15% demonstrated a greater decrease in iTNSS than placebo and the differences were statistically significant.

Nonclinical Toxicology Carcinogenesis, Mutagenesis, Impairment Of Fertility In 2-year carcinogenicity studies in rats and mice, azelastine hydrochloride did not show evidence of carcinogenicity at oral doses up to 30 mg/kg and 25 mg/kg, respectively.
These doses were approximately 150 and 60 times the maximum recommended human daily intranasal dose [MRHDID] on a mg/m2 basis.
Azelastine hydrochloride showed no genotoxic effects in the Ames test, DNA repair test, mouse lymphoma forward mutation assay, mouse micronucleus test, or chromosomal aberration test in rat bone marrow.
Reproduction and fertility studies in rats showed no effects on male or female fertility at oral doses up to 30 mg/kg (approximately 150 times the MRHDID in adults on a mg/m2 basis).
At 68.6 mg/kg (approximately 340 times the MRHDID on a mg/m2 basis), the duration of estrous cycles was prolonged and copulatory activity and the number of pregnancies were decreased.
The numbers of corpora lutea and implantations were decreased; however, pre-implantation loss was not increased.
Use In Specific Populations Pregnancy Pregnancy Category C There are no adequate and well-controlled clinical trials in pregnant women.
Azelastine hydrochloride has been shown to cause developmental toxicity in mice, rats, and rabbits.
Azelastine HCl nasal solution (nasal spray), 0.15% should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Teratogenic Effects In mice, azelastine hydrochloride caused embryo-fetal death, malformations (cleft palate; short or absent tail; fused, absent or branched ribs), delayed ossification, and decreased fetal weight at approximately 170 times the maximum recommended human daily intranasal dose (MRHDID) in adults (on a mg/m2 basis at a maternal oral dose of 68.6 mg/kg/day which also caused maternal toxicity as evidenced by decreased body weight).
Neither fetal nor maternal effects occurred in mice at approximately 7 times the MRHDID in adults (on a mg/m2 basis at a maternal oral dose of 3 mg/kg/day).
In rats, azelastine hydrochloride caused malformations (oligo- and brachydactylia), delayed ossification and skeletal variations, in the absence of maternal toxicity, at approximately 150 times the MRHDID in adults (on a mg/m2 basis at a maternal oral dose of 30 mg/kg/day).
Azelastine hydrochloride caused embryo-fetal death and decreased fetal weight and severe maternal toxicity at approximately 340 times the MRHDID (on a mg/m2 basis at a maternal oral dose of 68.6 mg/kg/day).
Neither fetal nor maternal effects occurred at approximately 15 times the MRHDID (on a mg/m2 basis at a maternal oral dose of 2 mg/kg/day).
In rabbits, azelastine hydrochloride caused abortion, delayed ossification and decreased fetal weight and severe maternal toxicity at approximately 300 times the MRHDID in adults (on a mg/m2 basis at a maternal oral dose of 30 mg/kg/day).
Neither fetal nor maternal effects occurred at approximately 3 times the MRHDID (on a mg/m2 basis at a maternal oral dose of 0.3 mg/kg/day).
Nursing Mothers It is not known whether azelastine hydrochloride is excreted in human milk.
Because many drugs are excreted in human milk, caution should be exercised when Azelastine HCl Nasal Solution (Nasal Spray), 0.15% is administered to a nursing woman.
Pediatric Use The safety and effectiveness of azelastine HCl nasal solution (nasal spray) in pediatric patients 6 to 17 years of age have been established [see Clinical Studies].
The safety and effectiveness of azelastine HCl nasal solution (nasal spray) in pediatric patients below 6 years of age have not been established.
Pediatric use information for patients ages 6 to 11 years of age for treatment of allergic rhinitis, including seasonal and perennial allergic rhinitis is approved for Meda Pharmaceuticals’ azelastine hydrochloride nasal spray product.
However, due to Meda Pharmaceuticals’ marketing exclusivity rights, this drug product is not labeled with that pediatric information.
Geriatric Use Clinical trials of azelastine HCl nasal solution (nasal spray) did not include sufficient numbers of patients 65 years of age and older to determine whether they respond differently from younger patients.
Other reported clinical experience has not identified differences in responses between the elderly and younger patients.
In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
