Use of Astelin Nasal Spray has been associated with somnolence [see WARNINGS AND PRECAUTIONS].
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect rates observed in practice.
Adverse experience information for Astelin Nasal Spray is derived from six placebo-and active-controlled, 2-day to 8-week clinical trials which included 391 patients, 12 years of age and older, with seasonal allergic rhinitis who received Astelin Nasal Spray at a dose of 2 sprays per nostril twice daily. In placebo-controlled efficacy trials, the incidence of discontinuation due to adverse reactions in patients receiving Astelin Nasal Spray and vehicle placebo was 2.2% and 2.8%, respectively.
Table 1 contains adverse reactions that were reported with frequencies ≥ 2% in the Astelin Nasal Spray 2 sprays per nostril twice daily treatment group and more frequently than placebo.

Reactions observed infrequently ( < 2% and exceeding placebo incidence) in patients who received Astelin Nasal Spray (2 sprays/nostril twice daily) in U.S. clinical trials in vasomotor rhinitis were similar to those observed in U.S. clinical trials in seasonal allergic rhinitis.
In controlled trials involving nasal and oral azelastine hydrochloride formulations, there were infrequent occurrences of hepatic transaminase elevations.
During the post approval use of Astelin Nasal Spray, the following adverse reactions have been identified. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Adverse reactions reported include: anaphylaxis, application site irritation, atrial fibrillation, chest pain, confusion, dyspnea, facial edema, involuntary muscle contractions, nasal sores, palpitations, paresthesia, parosmia, pruritus, rash, disturbance or loss of sense of smell and/or taste, tolerance, urinary retention, vision abnormal and xerophthalmia.
Concurrent use of Astelin Nasal Spray with alcohol or other central nervous system depressants should be avoided because reductions in alertness and impairment of central nervous system performance may occur [see WARNINGS AND PRECAUTIONS].
Included as part of the PRECAUTIONS section.
In clinical trials, the occurrence of somnolence has been reported in some patients taking Astelin Nasal Spray [see ADVERSE REACTIONS]. Patients should be cautioned against engaging in hazardous occupations requiring complete mental alertness and motor coordination such as operating machinery or driving a motor vehicle after administration of Astelin Nasal Spray. Concurrent use of Astelin Nasal Spray with alcohol or other central nervous system depressants should be avoided because additional reductions in alertness and additional impairment of central nervous system performance may occur [see DRUG INTERACTIONS].
See FDA-approved patient labeling (PATIENT INFORMATION and Instructions for Use).

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.
There are no adequate and well-controlled clinical studies in pregnant women. Azelastine hydrochloride has been shown to cause developmental toxicity in mice, rats, and rabbits. Astelin Nasal Spray should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
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).
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 Astelin Nasal Spray is administered to a nursing woman.
The safety and effectiveness of Astelin Nasal Spray for the treatment of symptoms of seasonal allergic rhinitis have been established for patients 5 years and older [see ADVERSE REACTIONS and Clinical Studies]. The safety and effectiveness of Astelin Nasal Spray for the treatment of vasomotor rhinitis have been established for patients 12 years and older [see ADVERSE REACTIONS and Clinical Studies]. The safety and effectiveness of Astelin Nasal Spray in pediatric patients below the age of 5 years with seasonal allergic rhinitis and in pediatric patients below the age of 12 years with vasomotor rhinitis have not been established.
Clinical trials of Astelin Nasal Spray did not include sufficient numbers of patients aged 65 and over 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.
There have been no reported overdosages with Astelin Nasal Spray. Acute overdosage by adults with this dosage form is unlikely to result in clinically significant adverse reactions, other than increased somnolence, since one bottle of Astelin Nasal Spray contains 30 mg of azelastine hydrochloride. Clinical trials in adults with single doses of the oral formulation of azelastine hydrochloride (up to 16 mg) have not resulted in increased incidence of serious adverse reactions. General supportive measures should be employed if overdosage occurs. There is no known antidote to Astelin Nasal Spray. Oral ingestion of antihistamines has the potential to cause serious adverse effects in young children. Accordingly, Astelin Nasal Spray should be kept out of the reach of children.
None.
Azelastine hydrochloride, a phthalazinone derivative, exhibits histamine H1-receptor antagonist activity in isolated tissues, animal models, and humans. Astelin 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.
In a placebo-controlled study (95 subjects with allergic rhinitis), there was no evidence of an effect of Astelin 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. These drugs had no effect on QTc based on analysis of serial electrocardiograms. At a dose approximately 8 times the maximum recommended dose, azelastine hydrochloride does not prolong the QTc interval to any clinically relevant extent.
After intranasal administration, the systemic bioavailability of azelastine hydrochloride is approximately 40%. Maximum plasma concentrations (Cmax) are achieved in 23 hours.
Azelastine hydrochloride administered intranasally at doses above two sprays per nostril twice daily for 29 days resulted in greater than proportional increases in Cmax and area under the curve (AUC) for azelastine.
Based on intravenous and oral administration, the steady-state volume of distribution 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.
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 intranasal dosing of azelastine hydrochloride to steady-state, plasma concentrations of desmethylazelastine range from 20-50% of azelastine concentrations. Limited data indicate that the metabolite profile is similar when azelastine hydrochloride is administered via the intranasal or oral route.
Based on intravenous and oral administration, the elimination half-life and plasma clearance are 22 hours and 0.5 L/h/kg, respectively. Approximately 75% of an oral dose of radiolabeled azelastine hydrochloride was excreted in the feces with less than 10% as unchanged azelastine.
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 normal 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.
Erythromycin: No significant pharmacokinetic interaction was observed with the coadministration of orally administered azelastine (4 mg twice daily) with erythromycin (500 mg three times daily for 7 days). In this study, co-administration of orally administered azelastine with erythromycin 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.
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%. No pharmacokinetic interaction was observed with co-administration of orally administered azelastine (4 mg twice daily) with ranitidine hydrochloride (150 mg twice daily). Oral co-administration of azelastine with ranitidine resulted in Cmax of 8.89 ±3.28 ng/mL and AUC of 88.22 ± 40.43 ng•h/mL for azelastine, whereas, azelastine when administered alone resulted in Cmax of 7.83 ± 4.06 ng/mL and AUC of 80.09 ± 43.55 ng•h/mL for azelastine.
Theophylline: No significant pharmacokinetic interaction was observed with the coadministration of an oral 4 mg dose of azelastine hydrochloride twice daily and theophylline 300 mg or 400 mg twice daily.
The efficacy and safety of Astelin Nasal Spray were evaluated in three placebo-controlled clinical trials of Astelin Nasal Spray including 322 patients with seasonal allergic rhinitis who received two sprays per nostril twice a day for up to 4 weeks. These trials included 55 pediatric patients ages 12 to 16 years. Assessment of efficacy was based on the 12-hour reflective Total Symptom Complex (TSC) and Major Symptom Complex (MSC). The MSC was calculated as the average of individual symptoms of nose blows, sneezes, runny nose/sniffles, itchy nose, and watery eyes as assessed by patients on a 0-5 categorical scale. Astelin Nasal Spray two sprays per nostril twice daily demonstrated a greater decrease in the MSC than placebo (Table 3).

In dose-ranging trials, administration of Astelin Nasal Spray two sprays per nostril twice daily resulted in a statistically significant decrease in symptoms compared to saline placebo within 3 hours after initial dosing and persisted over the 12-hour dosing interval.
The efficacy and safety of Astelin Nasal Spray were evaluated in two placebo-controlled clinical trials of Astelin Nasal Spray including 275 patients with seasonal allergic rhinitis who received one spray per nostril twice a day for up to 2 weeks. Assessment of efficacy was based on the 12hour reflective Total Nasal Symptom Score [rTNSS]. rTNSS is calculated as the sum of the patients scoring of four individual nasal symptoms (runny nose, sneezing, itchy nose, and nasal congestion) as assessed by patients on a 0-3 categorical scale. The primary efficacy endpoint was the change from Baseline to Day 14 in rTNSS. The mean change from baseline in rTNSS was greater in patients receiving Astelin Nasal Spray one spray per nostril twice daily than those receiving placebo (Table 4).

Two-week studies comparing the efficacy (and safety) of Astelin Nasal Spray two sprays per nostril twice daily versus one spray per nostril twice daily were not conducted.
The efficacy and safety of Astelin Nasal Spray were evaluated in two placebo-controlled clinical trials of Astelin Nasal Spray including 216 patients with vasomotor rhinitis who received two sprays per nostril twice a day for up to 4 weeks. These patients had vasomotor rhinitis for at least one year, negative skin tests to indoor and outdoor aeroallergens, negative nasal smears for eosinophils, and negative sinus X-rays. Astelin Nasal Spray demonstrated a significantly greater decrease in a symptom complex comprised of rhinorrhea, post nasal drip, nasal congestion, and sneezing compared to placebo.
