Atrovent Inhalation Solution, 0.02%
Prescribing Information
DESCRIPTION
The active ingredient, Atrovent monohydrate, USP, is an anticholinergic bronchodilator chemically described as 8-azoniabicyclo [3.2.1]- octane, 3-(3-hydroxy-1-oxo-2-phenylpropoxy)-8-methyl-8-(1-methylethyl)-, bromide, monohydrate (endo, syn)-, (+)-; a synthetic quaternary ammonium compound, chemically related to atropine.
Atrovent Monohydrate C20H30BrNO3-H2O Mol. Wt. 430.4
Atrovent is a white crystalline substance, freely soluble in water and lower alcohols. It is a quaternary ammonium compound and thus exists in an ionized state in aqueous solutions. It is relatively insoluble in non-polar media.
Atrovent Inhalation Solution is administered by oral inhalation with the aid of a nebulizer. It contains Atrovent, USP 0.02% (anhydrous basis) in a sterile, preservative-free, isotonic saline solution, pH-adjusted to 3.4 (3 to 4) with hydrochloric acid.
Chemical Structure for Atrovent Monohydrate
CLINICAL PHARMACOLOGY
Atrovent is an anticholinergic (parasympatholytic) agent that, based on animal studies, appears to inhibit vagally mediated reflexes by antagonizing the action of acetylcholine, the transmitter agent released from the vagus nerve.
Anticholinergics prevent the increases in intracellular concentration of cyclic guanosine monophosphate (cyclic GMP) that are caused by interaction of acetylcholine with the muscarinic receptor on bronchial smooth muscle.
The bronchodilation following inhalation of Atrovent is primarily a local, site-specific effect, not a systemic one. Much of an administered dose is swallowed but not absorbed, as shown by fecal excretion studies. Following nebulization of a 2 mg dose, a mean 7% of the dose was absorbed into the systemic circulation either from the surface of the lung or from the gastrointestinal tract. The half-life of elimination is about 1.6 hours after intravenous administration. Atrovent is minimally (0 to 9% in vitro) bound to plasma albumin and a1-acid glycoproteins. It is partially metabolized. Autoradiographic studies in rats have shown that Atrovent does not penetrate the blood-brain barrier. Atrovent has not been studied in patients with hepatic or renal insufficiency. It should be used with caution in those patient populations.
In controlled 12-week studies in patients with bronchospasm associated with chronic obstructive pulmonary disease (chronic bronchitis and emphysema) significant improvements in pulmonary function (FEV1 increases of 15% or more) occurred within 15 to 30 minutes, reached a peak in 1 to 2 hours, and persisted for periods of 4 to 5 hours in the majority of patients, with about 25% to 38% of the patients demonstrating increases of 15% or more for at least 7 to 8 hours. Continued effectiveness of Atrovent inhalation solution was demonstrated throughout the 12-week period. In addition, significant increases in forced vital capacity (FVC) have been demonstrated. However, Atrovent did not consistently produce significant improvement in subjective symptom scores nor in quality of life scores over the 12-week duration of study.
Additional controlled 12-week studies were conducted to evaluate the safety and effectiveness of Atrovent inhalation solution administered concomitantly with the beta adrenergic bronchodilator solutions metaproterenol and albuterol compared with the administration of each of the beta agonists alone. Combined therapy produced significant additional improvement in FEV1 and FVC. On combined therapy, the median duration of 15% improvement in FEV1 was 5 to 7 hours, compared with 3 to 4 hours in patients receiving a beta agonist alone.
INDICATIONS AND USAGE
Atrovent Inhalation Solution administered either alone or with other bronchodilators, especially beta adrenergics, is indicated as a bronchodilator for maintenance treatment of bronchospasm associated with chronic obstructive pulmonary disease, including chronic bronchitis and emphysema.
CONTRAINDICATIONS
Atrovent is contraindicated in known or suspected cases of hypersensitivity to Atrovent, or to atropine and its derivatives.
WARNINGS
The use of Atrovent inhalation solution as a single agent for the relief of bronchospasm in acute COPD exacerbation has not been adequately studied. Drugs with faster onset of action may be preferable as initial therapy in this situation. Combination of Atrovent and beta agonists has not been shown to be more effective than either drug alone in reversing the bronchospasm associated with acute COPD exacerbation.
Immediate hypersensitivity reactions may occur after administration of Atrovent, as demonstrated by rare cases of urticaria, angioedema, rash, bronchospasm and oropharyngeal edema.
PRECAUTIONS
General
Atrovent should be used with caution in patients with narrow-angle glaucoma, prostatic hypertrophy or bladder-neck obstruction.
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 the solution comes into direct contact with the eyes. Use of a nebulizer with mouthpiece rather than face mask may be preferable, to reduce the likelihood of the nebulizer solution reaching the eyes. Patients should be advised that Atrovent inhalation solution can be mixed in the nebulizer with albuterol or metaproterenol if used within one hour. Drug stability and safety of Atrovent Inhalation Solution when mixed with other drugs in a nebulizer have not been established. Patients should be reminded that Atrovent inhalation solution should be used consistently as prescribed throughout the course of therapy.
Drug Interactions
Atrovent has been shown to be a safe and effective bronchodilator when used in conjunction with beta adrenergic bronchodilators. Atrovent has also been used with other pulmonary medications, including methylxanthines and corticosteroids, without adverse drug interactions.
Carcinogenesis, Mutagenesis, Impairment of Fertility
Two-year oral carcinogenicity studies in rats and mice have revealed no carcinogenic potential at dietary doses up to 6 mg/kg/day of Atrovent.
Results of various mutagenicity studies were negative.
Fertility of male or female rats at oral doses up to 50 mg/kg/day was unaffected by Atrovent administration. At doses above 90 mg/kg increased resorption and decreased conception rates were observed.
Pregnancy TERATOGENIC EFFECTS
Pregnancy Category B
Oral reproduction studies performed in mice, rats and rabbits at doses of 10, 100, and 125 mg/kg respectively, and inhalation reproduction studies in rats and rabbits at doses of 1.5 and 1.8 mg/kg (or approximately 38 and 45 times the recommended human daily dose) respectively, have demonstrated no evidence of teratogenic effects as a result of Atrovent. However, no adequate or well-controlled studies have been conducted in pregnant women. Because animal reproduction studies are not always predictive of human response, Atrovent should be used during pregnancy only if clearly needed.
NURSING MOTHERS
It is not known whether Atrovent is excreted in human milk. Although lipid-insoluble quaternary bases pass into breast milk, it is unlikely that Atrovent would reach the infant to a significant extent, especially when taken by inhalation since Atrovent is not well absorbed systemically after inhalation or oral administration. However, because many drugs are excreted in human milk, caution should be exercised when Atrovent is administered to a nursing woman.
Pediatric Use
Safety and effectiveness in the pediatric population below the age of 12 have not been established.
ADVERSE REACTIONS
Adverse reaction information concerning Atrovent inhalation solution is derived from 12-week active-controlled clinical trials. Additional information is derived from foreign post-marketing experience and the published literature.
All adverse events, regardless of drug relationship, reported by three percent or more patients in the 12-week controlled clinical trials appear in the table below.
Additional adverse reactions reported in less than three percent of the patients treated with Atrovent include tachycardia, palpitations, eye pain, urinary retention, urinary tract infection and urticaria. Cases of precipitation or worsening of narrow-angle glaucoma, mydriasis and acute eye pain have been reported.
Lower respiratory adverse reactions (bronchitis, dyspnea and bronchospasm) were the most common events leading to discontinuation of Atrovent therapy in the 12-week trials. Headache, mouth dryness and aggravation of COPD symptoms are more common when the total daily dose of Atrovent equals or exceeds 2,000 mcg.
Allergic-type reactions such as skin-rash, angioedema of tongue, lips and face, urticaria, laryngospasm and anaphylactic reaction have been reported. Many of the patients had a history of allergies to other drugs and/or foods.
