INDICATIONS & USAGE Ipratropium bromide nasal solution 0.06% (Nasal Spray) is indicated for the symptomatic relief of rhinorrhea associated with the common cold or seasonal allergic rhinitis for adults and children age 5 years and older. Ipratropium bromide nasal solution 0.06% (Nasal Spray) does not relieve nasal congestion or sneezing associated with the common cold or seasonal allergic rhinitis. The safety and effectiveness of the use of ipratropium bromide nasal solution 0.06% (Nasal Spray) beyond four days in patients with the common cold or beyond three weeks in patients with seasonal allergic rhinitis has not been established.
CLINICAL PHARMACOLOGY Ipratropium bromide is an anticholinergic (parasympatholytic) agent which, based on animal studies, appears to inhibit vagally-mediated reflexes by antagonizing the action of acetylcholine, the transmitter agent released at the neuromuscular junctions in the lung. In humans, ipratropium bromide has anti-secretory properties and, when applied locally, inhibits secretions from the serous and seromucous glands lining the nasal mucosa. Ipratropium bromide is a quaternary amine that minimally crosses the nasal and gastrointestinal membranes and the blood-brain barrier, resulting in a reduction of the systemic anticholinergic effects (e.g., neurologic, ophthalmic, cardiovascular, and gastrointestinal effects) that are seen with tertiary anticholinergic amines. Absorption: Ipratropium bromide is poorly absorbed into the systemic circulation following oral administration (2-3%). Less than 20% of an 84 mcg per nostril dose was absorbed from the nasal mucosa of normal volunteers, induced-cold adult volunteers, naturally acquired common cold pediatric patients, or perennial rhinitis adult patients. Distribution: Ipratropium bromide is minimally bound (0 to 9% in vitro ) to plasma albumin and α 1 -acid glycoprotein. Its blood/plasma concentration ratio was estimated to be about 0.89. Studies in rats have shown that ipratropium bromide does not penetrate the blood-brain barrier. Metabolism: Ipratropium bromide is partially metabolized to ester hydrolysis products, tropic acid, and tropane. These metabolites appear to be inactive based on in vitro receptor affinity studies using rat brain tissue homogenates. Elimination: After intravenous administration of 2 mg ipratropium bromide to 10 healthy volunteers, the terminal half-life of ipratropium bromide was approximately 1.6 hours. The total body clearance and renal clearance were estimated to be 2,505 and 1,019 mL/min, respectively. The amount of the total dose excreted unchanged in the urine (Ae) within 24…

DOSAGE & ADMINISTRATION For Symptomatic Relief of Rhinorrhea Associated with the Common Cold: The recommended dose of ipratropium bromide nasal solution 0.06% (Nasal Spray) is two sprays (84 mcg) per nostril three or four times daily (total dose 504 to 672 mcg/day) in adults and children age 12 years and older. Optimum dosage varies with response of the individual patient. The recommended dose of ipratropium bromide nasal solution 0.06% (Nasal Spray) for children age 5-11 years is two sprays (84 mcg) per nostril three times daily (total dose of 504 mcg/day). The safety and effectiveness of the use of ipratropium bromide nasal solution 0.06% (Nasal Spray) beyond four days in patients with the common cold have not been established. For Symptomatic Relief of Rhinorrhea Associated with Seasonal Allergic Rhinitis: The recommended dose of ipratropium bromide nasal solution 0.06% (Nasal Spray) is two sprays (84 mcg) per nostril four times daily (total dose 672 mcg/day) in adults and children age 5 years and older. The safety and effectiveness of the use of ipratropium bromide nasal solution 0.06% (Nasal Spray) beyond three weeks in patients with seasonal allergic rhinitis have not been established. 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.
ADVERSE REACTIONS Adverse reaction information on ipratropium bromide nasal solution 0.06% (Nasal Spray) in patients with the common cold was derived from two multicenter, vehicle-controlled clinical trials involving 1,276 patients (195 patients on ipratropium bromide nasal solution 0.03% (Nasal Spray), 352 patients on ipratropium bromide nasal solution 0.06% (Nasal Spray), 189 patients on ipratropium bromide nasal solution 0.12% (Nasal Spray), 351 patients on vehicle and 189 patients receiving no treatment). Table 1 shows adverse events reported for patients who received ipratropium bromide nasal solution 0.06% (Nasal Spray) at the recommended dose of 84 mcg per nostril, or vehicle, administered three or four times daily, where the incidence is 1% or greater in the ipratropium bromide group and higher in the ipratropium bromide group than in the vehicle group.

Epistaxis reported by 5.4% of ipratropium bromide patients and 1.4% of vehicle patients, blood-tinged nasal mucus by 2.8% of ipratropium bromide patients and 0.9% of vehicle patients. Ipratropium bromide nasal solution 0.06% (Nasal Spray) was well tolerated by most patients. The most frequently reported adverse events were transient episodes of nasal dryness or epistaxis. The majority of these adverse events (96%) were mild or moderate in nature, none was considered serious, and none resulted in hospitalization. No patient required treatment for nasal dryness, and only three patients (<1%) required treatment for epistaxis, which consisted of local application of pressure or a…
CONTRAINDICATIONS Ipratropium bromide nasal solution 0.06% (Nasal Spray) is contraindicated in patients with a history of hypersensitivity to atropine or its derivatives, or to any of the other ingredients.
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 0.06% (Nasal Spray) should be stopped at once and alternative treatment should be considered.
