|
| dailymed-instance:dosage |
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. 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.

Mechanism of Action: Ipratropium bromide is an anticholinergic agent that inhibits vagally-mediated reflexes by antagonizing the action of acetylcholine at the cholinergic receptor. 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 membrane 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.<br/>Pharmacokinetics:<br/>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.<br/>Distribution: Ipratropium bromide is minimally bound (0 to 9%in vitro) to plasma albumin and��-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.<br/>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.<br/>Elimination: After intravenous administration of 2 mg ipratropium bromide to 10 healthy volunteers, the terminal half-life of ipratropium 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 hours was approximately one-half of the administered dose.<br/>Pediatrics: Following administration of 84 mcg of ipratropium bromide per nostril three times a day in patients 5-18 years old (n=42) with a naturally acquired common cold, the mean amount of the total dose excreted unchanged in the urine of 7.8% was comparable to 84 mcg per nostril four times a day in an adult induced common cold population (n=22) of 7.3 to 8.1%. Plasma ipratropium concentrations were relatively low (ranging from undetectable up to 0.62 ng/mL). No correlation of the amount of the total dose excreted unchanged in the urine (Ae) with age or gender was observed in the pediatric population.<br/>Special Populations: Gender does not appear to influence the absorption or excretion of nasally administered ipratropium bromide. The pharmacokinetics of ipratropium bromide have not been studied in patients with hepatic or renal insufficiency or in the elderly.<br/>Drug-Drug Interactions: No specific pharmacokinetic studies were conducted to evaluate potential drug-drug interactions.<br/>Pharmacodynamics: In two single-dose trials (n=17), doses up to 336 mcg of ipratropium bromide did not significantly affect pupillary diameter, heart rate, or systolic/diastolic blood pressure. Similarly, Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) in adult patients (n=22) with induced colds, (84 mcg/nostril four times a day) and in pediatric patients (n=45) with naturally acquired common colds (84 mcg/nostril three times a day) had no significant effects on pupillary diameter, heart rate, or systolic/diastolic blood pressure. Controlled clinical trials demonstrated that intranasal fluorocarbon-propelled ipratropium bromide does not alter physiologic nasal functions (e.g., sense of smell, ciliary beat frequency, mucociliary clearance, or the air conditioning capacity of the nose).<br/>Clinical Trials: The clinical trials for Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) were conducted in patients with rhinorrhea associated with naturally occurring common colds. In two controlled four day comparisons of Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) (84 mcg per nostril, administered three or four times daily; n=352) with its vehicle (n=351), there was a statistically significant reduction of rhinorrhea, as measured by both nasal discharge weight and the patients' subjective assessment of severity of rhinorrhea using a visual analogscale. These significant differences were evident within one hour following dosing. There was no effect of Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) on degree of nasal congestion or sneezing. The response to Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) did not appear to be affected by age or gender. No controlled clinical trials directly compared the efficacy of three times daily versus four times daily treatment.

General: Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) should be used with caution in patients with narrow-angle glaucoma, prostatic hypertrophy or bladder neck obstruction, particularly if they are receiving an anticholinergic by another route. Cases of precipitation or worsening of narrow-angle glaucoma and acute eye pain have been reported with direct eye contact of ipratropium bromide administered by oral inhalation.<br/>Information for Patients: Patients should be advised that temporary blurring of vision, precipitation or worsening of narrow-angle glaucoma or eye pain may result if Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) comes into direct contact with the eyes. Patients should be instructed to avoid spraying Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) in or around the eyes. Patients who experience eye pain, blurred vision, excessive nasal dryness or episodes of nasal bleeding should be instructed to contact their doctor. Patients should be reminded to carefully read and follow the accompanyingPatient's Instructions for Use.<br/>Drug Interactions: No controlled clinical trials were conducted to investigate potential drug-drug interactions. Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) is minimally absorbed into the systemic circulation; nonetheless, there is some potential for an additive interaction with other concomitantly administered medications with anticholinergic properties, including ipratropium bromide for oral inhalation.<br/>Carcinogenesis, Mutagenesis, Impairment of Fertility: In two-year carcinogenicity studies in rats and mice, ipratropium bromide at oral doses up to 6 mg/kg (approximately 70 and 35 times the maximum recommended daily intranasal dose in adults, respectively, and approximately 45 and 25 times the maximum recommended daily intranasal dose in children, respectively, on a mg/mbasis) showed no carcinogenic activity. Results of various mutagenicity studies (Ames test, mouse dominant lethal test, mouse micronucleus test, and chromosome aberration of bone marrow in Chinese hamsters) were negative. Fertility of male or female rats was unaffected by ipratropium bromide at oral doses up to 50 mg/kg (approximately 600 times the maximum recommended daily intranasal dose in adults on a mg/mbasis). At an oral dose of 500 mg/kg (approximately 16,000 times the maximum recommended daily intranasal dose in adults on a mg/mbasis), ipratropium bromide produced a decrease in the conception rate.<br/>Pregnancy:<br/>TERATOGENIC EFFECTS:<br/>Nursing Mothers: It is known that some ipratropium bromide is systemically absorbed following nasal administration; however, the portion which may be excreted in human milk is unknown. Although lipid-insoluble quaternary bases pass into breast milk, the minimal systemic absorption makes it unlikely that ipratropium bromide would reach the infant in an amount sufficient to cause a clinical effect. However, because many drugs are excreted in human milk, caution should be exercised when Ipratropium Bromide Nasal Solution0.06% (Nasal Spray) is administered to a nursing woman.<br/>Pediatric Use: The safety of Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) at a dose of two sprays (84 mcg) per nostril three times a day (total dose 504 mcg/day) for two to four days has been demonstrated in two clinical trials involving 362 pediatric patients 5-11 years of age with naturally acquired common colds. In this pediatric population, Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) had an adverse event profile similar to that observed in adolescent and adult patients. When Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) was concomitantly administered with an oral decongestant (pseudoephedrine HCl) in 122 children ages 5-12 years, and concomitantly administered with an oral decongestant/antihistamine combination (pseudoephedrine HCl/chlorpheniramine maleate) in 123 children ages 5-12 years, adverse event profiles were similar to ipratropium bromide alone. The effectiveness of Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) for the treatment of rhinorrhea associated with the common cold in this pediatric age group is based on extrapolation of the demonstrated efficacyof Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) in adolescents and adults with the condition and the likelihood that the disease course, pathophysiology, and the drug's effect are substantially similar to that of adults. The recommended dose for common cold for the pediatric population is based on cross-study comparisons of the efficacy of Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) in adult and pediatric patients and on its safety profile in both adults and pediatric patients. The safety and effectiveness of Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) in pediatric patients under 5 years of age have not been established.

| dailymed-instance:overdosag... |
Acute overdosage by intranasal administration is unlikely since ipratropium bromide is not well absorbed systemically after intranasal or oral administration. Following administration of a 20 mg oral dose (equivalent to ingesting more than two bottles of Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray)) to 10 male volunteers, no change in heart rate or blood pressure was noted. Following a 2 mg intravenous infusion over 15 minutes to the same 10 male volunteers, plasma ipratropium concentrations of 22-45 ng/mL were observed (>100 times the concentrations observed following intranasal administration). Following intravenous infusion these 10 volunteers had a mean increase of heart rate of 50 bpm and less than 20 mm Hg change in systolic or diastolic blood pressure at the time of peak ipratropium levels. Oral median lethal doses of ipratropium bromide were greater than 1,000 mg/kg in mice (approximately 6,000 and 3,800 times the maximum recommended daily intranasal dose in adults and children, respectively, on a mg/mbasis) 1,700 mg/kg in rats (approximately 21,000 and 13,000 times the maximum recommended daily intranasal dose in adults and children, respectively, on a mg/mbasis) and 400 mg/kg in dogs (approximately 16,000 and 10,000 times the maximum recommended daily intranasal dose in adults and children, respectively, on a mg/mbasis).

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 Spray 0.12%, 351 patients on vehicle and 189 patients receiving no treatment). The following table 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 Nasal Solution 0.06% (Nasal Spray) group and higher in the Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) group than in the vehicle group. 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 moisturizing agent (e.g., petroleum jelly). No patient receiving Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) was discontinued from the trial due to either nasal dryness or bleeding. Adverse events reported by less than 1% of the patients receiving Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) during the controlled clinical trials that are potentially related to Ipratropium Bromide Nasal Solution 0.06% (Nasal Spray) local effects or systemic anticholinergic effects include: taste perversion, nasal burning, conjunctivitis, coughing, dizziness, hoarseness, palpitation, pharyngitis, tachycardia, thirst, tinnitus and blurred vision. No controlled trial was conducted to address the relative incidence of adverse events for three times daily versus four times daily therapy. Additional anticholinergic effects noted with other ipratropium bromide dosage forms (Ipratropium Bromide Inhalation Solution, Ipratropium Bromide Inhalation Aerosol and Ipratropium Bromide Nasal Solution 0.03% (Nasal Spray)) include: precipitation or worsening of narrow-angle glaucoma, urinary retention, prostate disorders, constipation andbowel obstruction. There were no reports of allergic-type reactions in the controlled clinical trials. Allergic-type reactions such as skin rash, angioedema of the tongue, lips and face, urticaria, laryngospasm and anaphylactic reactions have been reported with other ipratropium bromide products.
