📄 Full prescribing information FDA SPL
🎯 Indications and Usage ▾
INDICATIONS AND USAGE Azelastine hydrochloride ophthalmic solution is indicated for the treatment of itching of the eye associated with allergic conjunctivitis.
⏱️ Dosage and Administration ▾
DOSAGE AND ADMINISTRATION The recommended dose is one drop instilled into each affected eye twice a day.
⛔ Contraindications ▾
CONTRAINDICATIONS Azelastine hydrochloride ophthalmic solution is contraindicated in persons with known or suspected hypersensitivity to any of its components.
⚠️ Warnings ▾
WARNINGS Azelastine hydrochloride ophthalmic solution is for ocular use only and not for injection or oral use.
🤒 Adverse Reactions ▾
ADVERSE REACTIONS In controlled multiple-dose studies where patients were treated for up to 56 days, the most frequently reported adverse reactions were transient eye burning/stinging (approximately 30%), headaches (approximately 15%) and bitter taste (approximately 10%). The occurrence of these events was generally mild. The following events were reported in 1 to 10% of patients: asthma, conjunctivitis, dyspnea, eye pain, fatigue, influenza-like symptoms, pharyngitis, pruritus, rhinitis and temporary blurring.
Some of these events were similar to the underlying disease being studied.
🤰 Pregnancy ▾
Pregnancy Teratogenic Effects: Pregnancy Category C. Azelastine hydrochloride has been shown to be embryotoxic, fetotoxic, and teratogenic (external and skeletal abnormalities) in mice at an oral dose of 68.6 mg/kg/day (57,000 times the recommended ocular human use level). At an oral dose of 30 mg/kg/day (25,000 times the recommended ocular human use level), delayed ossification (undeveloped metacarpus) and the incidence of 14 th rib were increased in rats.
At 68.6 mg/kg/day (57,000 times the maximum recommended ocular human use level) azelastine hydrochloride caused resorption and fetotoxic effects in rats. The relevance to humans of these skeletal findings noted at only high drug exposure levels is unknown. There are no adequate and well-controlled studies in pregnant women.
Azelastine hydrochloride ophthalmic solution should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
🧒 Pediatric Use ▾
Pediatric Use Safety and effectiveness in pediatric patients below the age of 3 have not been established.
🧓 Geriatric Use ▾
Geriatric Use No overall differences in safety or effectiveness have been observed between elderly and younger adult patients.
🧬 Clinical Pharmacology ▾
CLINICAL PHARMACOLOGY Azelastine hydrochloride is a relatively selective histamine H 1 antagonist and an inhibitor of the release of histamine and other mediators from cells (e.g., mast cells) involved in the allergic response. Based on in-vitro studies using human cell lines, inhibition of other mediators involved in allergic reactions (e.g., leukotrienes and PAF) has been demonstrated with azelastine hydrochloride. Decreased chemotaxis and activation of eosinophils has also been demonstrated.
Pharmacokinetics and Metabolism Absorption of azelastine following ocular administration was relatively low. A study in symptomatic patients receiving one drop of azelastine hydrochloride ophthalmic solution in each eye two to four times a day (0.06 to 0.12 mg azelastine hydrochloride) demonstrated plasma concentrations of azelastine hydrochloride to generally be between 0.02 and 0.25 ng/mL after 56 days of treatment. Three of nineteen patients had quantifiable amounts of N-desmethylazelastine that ranged from 0.25 to 0.87 ng/mL at Day 56.
Based on intravenous and oral administration, the elimination half-life, steady-state volume of distribution and plasma clearance were 22 hours,
14.5 L/kg and
0.5L/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. Azelastine hydrochloride is oxidatively metabolized to the principal metabolite, N-desmethylazelastine, by the cytochrome P450 enzyme system.
In-vitro studies in human plasma indicate that the plasma protein binding of azelastine and N-desmethylazelastine are approximately 88% and 97%, respectively. Clinical Trials In a conjunctival antigen challenge study, azelastine hydrochloride ophthalmic solution was more effective than its vehicle in preventing itching associated with allergic conjunctivitis. Azelastine hydrochloride ophthalmic solution had a rapid (within 3 minutes) onset of effect and a duration of effect of approximately 8 hours for the prevention of itching.
In environmental studies, adult and pediatric, patients with seasonal allergic conjunctivitis were treated with azelastine hydrochloride ophthalmic solution for two to eight weeks. In these studies, azelastine hydrochloride ophthalmic solution was more effective than its vehicle in relieving itching associated with allergic conjunctivitis.
