Ipratroprium Bromide for Hay Fever

INDICATIONS AND USAGE: Ipratropium Bromide Nasal Solution 0.03% (Nasal Spray) is indicated for the symptomatic relief of rhinorrhea associated with allergic and nonallergic perennial rhinitis in adults and children age 6 years and older. Ipratropium Bromide Nasal Solution 0.03% (Nasal Spray) does not relieve nasal congestion, sneezing, or postnasal drip associated with allergic or nonallergic perennial rhinitis.

DOSAGE AND ADMINISTRATION: The recommended dose of Ipratropium Bromide Nasal Solution 0.03% (Nasal Spray) is two sprays (42 mcg) per nostril two or three times daily (total dose 168 to 252 mcg/day) for the symptomatic relief of rhinorrhea associated with allergic and nonallergic perennial rhinitis in adults and children age 6 years and older. Optimum dosage varies with the response of the individual patient. Initial pump priming requires seven sprays of the pump. If used regularly as recommended, no further priming is required. If not used for more than 24 hours, the pump will require two sprays, or if not used for more than seven days, the pump will require seven sprays to reprime. Avoid spraying into eyes.

WARNINGS: Immediate hypersensitivity reactions may occur after administration of ipratropium bromide, as demonstrated by urticaria, angioedema, rash, bronchospasm, anaphylaxis, and oropharyngeal edema. If such a reaction occurs, therapy with Ipratropium Bromide Nasal Solution 0.03% (Nasal Spray) should be stopped at once and alternative treatment should be considered.

Drug Interactions: No controlled clinical trials were conducted to investigate potential drug-drug interactions. There is potential for an additive interaction with other concomitantly administered medications with anticholinergic properties, including Ipratropium Bromide Nasal Solution 0.03% (Nasal Spray) for oral inhalation.

ADVERSE REACTIONS: Adverse reaction information on Ipratropium Bromide Nasal Solution 0.03% (Nasal Spray) in patients with perennial rhinitis was derived from four multicenter, vehicle-controlled clinical trials involving 703 patients (356 patients on ipratropium bromide and 347 patients on vehicle), and a one-year, open-label, follow-up trial. In three of the trials, patients received Ipratropium Bromide Nasal Solution 0.03% (Nasal Spray) three times daily, for eight weeks. In the other trial, Ipratropium Bromide Nasal Solution 0.03% (Nasal Spray) was given to patients two times daily for four weeks. Of the 285 patients who entered the open-label, follow-up trial, 232 were treated for 3 months, 200 for 6 months, and 159 up to one year. The majority (>86%) of patients treated for one year were maintained on 42 mcg per nostril, two or three times daily, of Ipratropium Bromide Nasal Solution 0.03% (Nasal Spray). Table 1 shows adverse events, and the frequency that these adverse events led to the discontinuation of treatment, reported for patients who received Ipratropium Bromide Nasal Solution 0.03% (Nasal Spray) at the recommended dose of 42 mcg per nostril, or vehicle two or three times daily for four or eight weeks. Only adverse events reported with an incidence of at least 2.0% in the ipratropium bromide group and higher in the ipratropium bromide group than in the vehicle group are shown.

Ipratropium Bromide Nasal Solution 0.03% (Nasal Spray) was well tolerated by most patients. The most frequently reported nasal adverse events were transient episodes of nasal dryness or epistaxis. These adverse events were mild or moderate in nature, none was considered serious, none resulted in hospitalization and most resolved spontaneously or following a dose reduction. Treatment for nasal dryness and epistaxis was required infrequently (2% or less) and consisted of local application of pressure or a moisturizing agent (e.g., petroleum jelly or saline nasal spray). Patient discontinuation for epistaxis or nasal dryness was infrequent in both the controlled (0.3% or less) and one-year, open-label (2% or less) trials. There was no evidence of nasal rebound (i.e., a clinically significant increase in rhinorrhea, posterior nasal drip, sneezing or nasal congestion severity compared to baseline) upon discontinuation of double-blind therapy in these trials. Adverse events reported by less than 2% of the patients receiving Ipratropium Bromide Nasal Solution 0.03% (Nasal Spray) during the controlled clinical trials or during the open-label follow-up trial, which are potentially related to ipratropium bromide’s local effects or systemic anticholinergic effects include: dry mouth/throat, dizziness, ocular irritation, blurred vision, conjunctivitis, hoarseness, cough, and taste perversion. There were infrequent reports of skin rash in both the controlled and uncontrolled clinical studies.
