Pulmicort Respules
Budesonide · Suspension · Respiratory (inhalation)
Uses
1 INDICATIONS AND USAGE PULMICORT RESPULES ® is an inhaled corticosteroid indicated for:
• Maintenance treatment of asthma and as prophylactic therapy in children 12 months to 8 years of age ( 1 ) Limitations of Use: Not indicated for the relief of acute bronchospasm ( 1 ) 1.1 Maintenance Treatment of Asthma PULMICORT RESPULES is indicated for the maintenance treatment of asthma and as prophylactic therapy in children 12 months to 8 years of age. Limitations of Use :
• PULMICORT RESPULES is NOT indicated for the relief of acute bronchospasm.
Dosage and administration
The recommended starting dose and highest recommended dose of PULMICORT RESPULES, based on prior asthma therapy, are listed in the following table. Previous Therapy Recommended Starting Dose Highest Recommended Dose Bronchodilators alone 0.5 mg total daily dose administered either once daily or twice daily in divided doses 0.5 mg total daily dose Inhaled Corticosteroids 0.5 mg total daily dose administered either once daily or twice daily in divided doses 1 mg total daily dose Oral Corticosteroids 1 mg total daily dose administered either as 0.5 mg twice daily or 1 mg once daily 1 mg total daily dose Recommended dosing based on previous therapy ( 2 ). Start with the lowest recommended dose:
• Bronchodilators alone: 0.5 mg once daily or 0.25 mg twice daily
• Inhaled corticosteroids: 0.5 mg once daily or 0.25 mg twice daily up to 0.5 mg twice daily
• Oral corticosteroids: 0.5 mg twice daily or 1 mg once daily
• In symptomatic children not responding to non-steroidal therapy, a starting dose of 0.25 mg once daily may be considered
• If once-daily treatment does not provide adequate control, the total daily dose should be increased and/or administered as a divided dose. Once asthma stability is achieved, titrate the dose downwards
• For inhalation use via compressed air driven jet nebulizers only (not for use with ultrasonic devices). Not for injection. ( 2.2 ) 2.1 Dosing Recommendations Dosing recommendations based on previous therapy are as follows:
• Bronchodilators alone: 0.5 mg once daily or 0.25 mg twice daily
• Inhaled corticosteroids: 0.5 mg once daily or 0.25 mg twice daily up to 0.5 mg twice daily
• Oral corticosteroids: 0.5 mg twice daily or 1 mg once daily In symptomatic children not responding to non-steroidal therapy, a starting dose of 0.25 mg once daily may be considered. If once-daily treatment does not provide adequate control, the total daily dose should be increased and/or administered as a divided dose. In all patients, it is desirable to downward-titrate to the lowest effective dose once asthma stability is achieved. 2.2 Directions for Use PULMICORT RESPULES should be administered via jet nebulizer connected to an air compressor with an adequate air flow, equipped with a mouthpiece or suitable face mask. Ultrasonic nebulizers are not suitable for the adequate administration of PULMICORT RESPULES and, therefore, are NOT recommended. The effects of mixing PULMICORT RESPULES with other nebulizable medications have not been adequately assessed. PULMICORT RESPULES should be administered separately in the nebulizer [see Patient Counseling Information (17.1) ]. A Pari-LC-Jet Plus Nebulizer (with face mask or mouthpiece) connected to a Pari Master compressor was used to deliver PULMICORT RESPULES to each patient in 3 U.S. controlled clinical studies. The safety and efficacy of PULMICORT RESPULES delivered by other nebulizers and compressors have not been established.
Dosage forms and strengths
3 DOSAGE FORMS AND STRENGTHS PULMICORT RESPULES is available in three strengths, each containing 2 mL: 0.25 mg/2 mL, 0.5 mg/2 mL, and 1 mg/2 mL. PULMICORT RESPULES is supplied in sealed aluminum foil envelopes containing one plastic strip of five single-dose RESPULES ampules together with patient instructions for use. There are 30 RESPULES ampules in a carton. Each single-dose RESPULES ampule contains 2 mL of sterile liquid suspension. Inhalation suspension: 0.25 mg/2 mL, 0.5 mg/2 mL, 1 mg/2 mL ( 3 )
Contraindications
The use of PULMICORT RESPULES is contraindicated in the following conditions:
• Primary treatment of status asthmaticus or other acute episodes of asthma where intensive measures are required.
• Hypersensitivity to budesonide or any of the ingredients of PULMICORT RESPULES [see Warnings and Precautions (5.3) , Description (11) , Adverse Reactions (6.2) ] .
• Primary treatment of status asthmaticus or other acute episodes of asthma where intensive measures are required ( 4 )
• Hypersensitivity to any of the ingredients in PULMICORT RESPULES ( 4 )
Warnings and precautions
• Localized Infections: Candida albicans infection of the mouth and throat may occur. Monitor patients periodically for signs of adverse effects on the oral cavity. Advise patients to rinse the mouth following inhalation ( 5.1 )
• Deterioration of Disease and Acute Asthma Episodes: Do not use for the relief of acute bronchospasm ( 5.2 )
• Hypersensitivity Reactions: Anaphylaxis, rash, contact dermatitis, urticaria, angioedema, and bronchospasm have been reported with use of PULMICORT RESPULES. Discontinue PULMICORT RESPULES if such reactions occur ( 5.3 )
• Immunosuppression: Potential worsening of infections (e.g., existing tuberculosis, fungal, bacterial, viral, or parasitic infection; or ocular herpes simplex). Use with caution in patients with these infections. More serious or even fatal course of chickenpox or measles can occur in susceptible patients ( 5.4 )
• Transferring Patients from Systemic Corticosteroid Therapy: Risk of impaired adrenal function when transferring from oral steroids. Taper patients slowly from systemic corticosteroids if transferring to PULMICORT RESPULES ( 5.5 )
• Hypercorticism and Adrenal Suppression: May occur with very high dosages or at the regular dosage in susceptible individuals. If such changes occur, reduce PULMICORT RESPULES slowly ( 5.6 )
• Reduction in Bone Mineral Density with Long-term Administration: Monitor patients with major risk factors for decreased bone mineral content ( 5.7 )
• Effects on Growth: Monitor growth of pediatric patients ( 5.8 )
• Glaucoma and Cataracts: Close monitoring is warranted ( 5.9 )
• Paradoxical Bronchospasm: Discontinue PULMICORT RESPULES and institute alternative therapy if paradoxical bronchospasm occurs ( 5.10 )
• Eosinophilic Conditions and Churg-Strauss Syndrome: Be alert to eosinophilic conditions ( 5.11 ) 5.1 Local Effects In clinical trials with PULMICORT RESPULES, localized infections with Candida albicans occurred in the mouth and pharynx in some patients. The incidences of localized infections of Candida albicans were similar between the placebo and PULMICORT RESPULES treatment groups. If these infections develop, they may require treatment with appropriate local or systemic antifungal therapy and/or discontinuance of treatment with PULMICORT RESPULES. Patients should rinse the mouth after inhalation of PULMICORT RESPULES. 5.2 Deterioration of Disease and Acute Asthma Episodes PULMICORT RESPULES is not a bronchodilator and is not indicated for the rapid relief of acute bronchospasm or other acute episodes of asthma. Patients should be instructed to contact their physician immediately if episodes of asthma not responsive to their usual doses of bronchodilators occur during the course of treatment with PULMICORT RESPULES. During such episodes, patients may require therapy with oral corticosteroids. 5.3 Hypersensitivity Reactions Including Anaphylaxis Hypersensitivity reactions including anaphylaxis, rash, contact dermatitis, urticaria, angioedema, and bronchospasm have been reported with use of PULMICORT RESPULES. Discontinue PULMICORT RESPULES if such reactions occur [see Contraindications (4) ]. 5.4 Immunosuppression Patients who are on drugs that suppress the immune system are more susceptible to infection than healthy individuals. Chicken pox and measles, for example, can have a more serious or even fatal course in susceptible children or adults using corticosteroids. In children or adults who have not had these diseases, or been properly immunized, particular care should be taken to avoid exposure. How the dose, route, and duration of corticosteroid administration affect the risk of developing a disseminated infection is not known. The contribution of the underlying disease and/or prior corticosteroid treatment to the risk is also not known. If exposed to chicken pox, therapy with varicella zoster immune globulin (VZIG) or pooled intravenous immunoglobulin (IVIG), as appropriate, may be indicated. If exposed to measles, prophylaxis with pooled intramuscular immunoglobulin (IG) may be indicated (see the respective package inserts for complete VZIG and IG prescribing information). If chicken pox develops, treatment with antiviral agents may be considered. The clinical course of chicken pox or measles infection in patients on inhaled corticosteroids has not been studied. However, a clinical study has examined the immune responsiveness of asthma patients 12 months to 8 years of age who were treated with PULMICORT RESPULES. An open-label non-randomized clinical study examined the immune responsiveness of varicella vaccine in 243 asthma patients 12 months to 8 years of age who were treated with PULMICORT RESPULES 0.25 mg to 1 mg daily (n=151) or non-corticosteroid asthma therapy (n=92) (i.e., beta 2 -agonists, leukotriene receptor antagonists, cromones). The percentage of patients developing a seroprotective antibody titer of ≥5.0 (gpELISA value) in response to the vaccination was similar in patients treated with PULMICORT RESPULES (85%) compared to patients treated with non-corticosteroid asthma therapy (90%). No patient treated with PULMICORT RESPULES developed chicken pox as a result of vaccination. Inhaled corticosteroids should be used with caution, if at all, in patients with active or quiescent tuberculosis infection of the respiratory tract, untreated systemic fungal, bacterial, viral, or parasitic infections; or ocular herpes simplex. 5.5 Transferring Patients from Systemic Corticosteroid Therapy Particular care is needed for patients who are transferred from systemically active corticosteroids to inhaled corticosteroids because deaths due to adrenal insufficiency have occurred in asthmatic patients during and after transfer from systemic corticosteroids to less systemically available inhaled corticosteroids. After withdrawal from systemic corticosteroids, a number of months are required for recovery of hypothalamic-pituitary-adrenal (HPA)-axis function.
Side effects
Systemic and inhaled corticosteroid use may result in the following:
• Candida albicans Infection [see Warnings and Precautions (5.1) ]
• Hypersensitivity Reactions Including Anaphylaxis [see Warnings and Precautions (5.3) ]
• Immunosuppression [see Warnings and Precautions (5.4) ]
• Hypercorticism and Adrenal Suppression [see Warnings and Precautions (5.6) ]
• Reduction in Bone Mineral Density [see Warnings and Precautions (5.7) ]
• Growth Effects in Pediatric Patients [see Warnings and Precautions (5.8) , Use in Specific Populations (8.4) ]
• Glaucoma, Increased Intraocular Pressure and Cataracts [see Warnings and Precautions (5.9) ]
• Eosinophilic Conditions and Churg-Strauss Syndrome [see Warnings and Precautions (5.11) ] Most common adverse reactions (incidence > 3%) are respiratory infection, rhinitis, coughing, otitis media, viral infection, moniliasis, gastroenteritis, vomiting, diarrhea, abdominal pain, ear infection, epistaxis, conjunctivitis, rash ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact AstraZeneca at 1–800–236–9933 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The incidence of common adverse reactions is based on three double-blind, placebo-controlled, randomized U.S. clinical trials in which 945 patients, 12 months to 8 years of age, (98 patients ≥12 months and <2 years of age; 225 patients ≥2 and <4 years of age; and 622 patients ≥4 and ≤8 years of age) were treated with PULMICORT RESPULES (0.25 to 1 mg total daily dose for 12 weeks) or vehicle placebo. The incidence and nature of adverse events reported for PULMICORT RESPULES was comparable to that reported for placebo. The following table shows the incidence of adverse events in U.S. controlled clinical trials, regardless of relationship to treatment, in patients previously receiving bronchodilators and/or inhaled corticosteroids. This population included a total of 605 male and 340 female patients and 78.4% were Caucasian, 13.8% African American, 5.5% Hispanic and 2.3% Other. Table 1 – Adverse Reactions occurring at an incidence of ≥3% in at least one active treatment group where the incidence was higher with PULMICORT RESPULES than placebo Adverse Events Vehicle Placebo (n=227) % PULMICORT RESPULES Total Daily Dose 0.25 mg (n=178) % 0.5 mg (n=223) % 1 mg (n=317) % Respiratory System Disorder Respiratory Infection 36 34 35 38 Rhinitis 9 7 11 12 Coughing 5 5 9 8 Resistance Mechanism Disorders Otitis Media 11 12 11 9 Viral Infection 3 4 5 3 Moniliasis 2 4 3 4 Gastrointestinal System Disorders Gastroenteritis 4 5 5 5 Vomiting 3 2 4 4 Diarrhea 2 4 4 2 Abdominal Pain 2 3 2 3 Hearing and Vestibular Disorders Ear Infection 4 2 4 5 Platelet, Bleeding and Clotting Disorders Epistaxis 1 2 4 3 Vision Disorders Conjunctivitis 2 <1 4 2 Skin and Appendages Disorders Rash 3 <1 4 2 The information below includes all adverse reactions by system organ class with an incidence of 1 to < 3%, in at least one PULMICORT RESPULES treatment group where the incidence was higher with PULMICORT RESPULES than with placebo, regardless of relationship to treatment. Blood and lymphatic system disorders: cervical lymphadenopathy Ear and labyrinth disorders: earache General disorders and administration site conditions: fatigue, flu-like disorder Immune system disorders: allergic reaction Infections and infestations: eye infection, herpes simplex, external ear infection, infection Injury, poisoning and procedural complication: fracture Metabolism and nutrition disorders: anorexia Musculoskeletal and connective tissue disorders: myalgia Nervous system disorders: hyperkinesia Psychiatric disorders: emotional lability Respiratory, thoracic, and mediastinal disorders: chest pain, dysphonia, stridor Skin and subcutaneous tissue disorders: contact dermatitis, eczema, pustular rash, pruritus, purpura The incidence of reported adverse events was similar between the 447 PULMICORT RESPULES-treated (mean total daily dose 0.5 to 1 mg) and 223 conventional therapy-treated pediatric asthma patients followed for one year in three open-label studies. 6.2 Postmarketing Experience The following adverse reactions have been reported during post-approval use of PULMICORT RESPULES. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Some of these adverse reactions may also have been observed in clinical studies with PULMICORT RESPULES.
Drug interactions
Strong Cytochrome P450 3A4 Inhibitors (e.g., ritonavir): Use with caution. May cause increased systemic corticosteroid effects ( 5.12 , 7.1 ) 7.1 Inhibitors of Cytochrome P450 3A4 The main route of metabolism of corticosteroids, including budesonide, is via cytochrome P450 (CYP) isoenzyme 3A4 (CYP3A4). After oral administration of ketoconazole, a strong inhibitor of CYP3A4, the mean plasma concentration of orally administered budesonide increased. Concomitant administration of a CYP3A4 inhibitor may inhibit the metabolism of, and increase the systemic exposure to, budesonide. Caution should be exercised when considering the coadministration of PULMICORT RESPULES with long-term ketoconazole and other known strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, telithromycin) [see Warnings and Precautions (5.12) , Clinical Pharmacology (12.3) ] .
Use in specific populations
8.1 Pregnancy Risk Summary There are no adequate well-controlled studies of PULMICORT RESPULES in pregnant women. However, there are published studies on the use of budesonide, the active ingredient in PULMICORT RESPULES, in pregnant women. In animal reproduction studies, budesonide, administered by the subcutaneous route, caused structural abnormalities, was embryocidal, and reduced fetal weights in rats and rabbits at less than the maximum recommended human daily inhalation dose (MRHDID), but these effects were not seen in rats that received inhaled doses approximately 2 times the MRHDID ( see Data ). Studies of pregnant women have not shown that inhaled budesonide increases the risk of abnormalities when administered during pregnancy. Experience with oral corticosteroids suggests that rodents are more prone to structural abnormalities from corticosteroid exposure than humans. The estimated background risk of major birth defects and miscarriage of the indicated populations is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal risk In women with poorly or moderately controlled asthma, there is an increased risk of several perinatal adverse outcomes such as preeclampsia in the mother and prematurity, low birth weight, and small for gestational age in the neonate. Pregnant women with asthma should be closely monitored and medication adjusted as necessary to maintain optimal asthma control. Labor or Delivery There are no well-controlled human studies that have investigated the effects of PULMICORT RESPULES during labor and delivery. Data Human Data Studies of pregnant women have not shown that inhaled budesonide increases the risk of abnormalities when administered during pregnancy. The results from a large population-based prospective cohort epidemiological study reviewing data from three Swedish registries covering approximately 99% of the pregnancies from 1995-1997 (i.e., Swedish Medical Birth Registry; Registry of Congenital Malformations; Child Cardiology Registry) indicate no increased risk for congenital malformations from the use of inhaled budesonide during early pregnancy. Congenital malformations were studied in 2014 infants born to mothers reporting the use of inhaled budesonide for asthma in early pregnancy (usually 10-12 weeks after the last menstrual period), the period when most major organ malformations occur. The rate of recorded congenital malformations was similar compared to the general population rate (3.8% vs. 3.5%, respectively). In addition, after exposure to inhaled budesonide, the number of infants born with orofacial clefts was similar to the expected number in the normal population (4 children vs. 3.3, respectively). These same data were utilized in a second study bringing the total to 2534 infants whose mothers were exposed to inhaled budesonide. In this study, the rate of congenital malformations among infants whose mothers were exposed to inhaled budesonide during early pregnancy was not different from the rate for all newborn babies during the same period (3.6%). Animal Data In a fertility and reproduction study, male rats were subcutaneously dosed for 9 weeks and females for 2 weeks prior to pairing and throughout the mating period. Females were dosed up until weaning of their offspring. Budesonide caused a decrease in prenatal viability and viability in the pups at birth and during lactation, along with a decrease in maternal body-weight gain, at doses 0.2 times the MRHDID (on a mcg/m 2 basis at maternal subcutaneous doses of 20 mcg/kg/day and above). No such effects were noted at a dose 0.05 times the MRHDID (on a mcg/m 2 basis at a maternal subcutaneous dose of 5 mcg/kg/day). In an embryo-fetal development study in pregnant rabbits dosed during the period of organogenesis from gestation days 6-18, budesonide produced fetal loss, decreased fetal weight, and skeletal abnormalities at doses 0.5 times the MRHDID (on a mcg/m 2 basis at a maternal subcutaneous dose of 25 mcg/kg/day). In an embryo-fetal development study in pregnant rats dosed during the period of organogenesis from gestation days 6-15, budesonide produced similar adverse fetal effects at doses approximately 5 times the MRHDID (on a mcg/m 2 basis at a maternal subcutaneous dose of 500 mcg/kg/day). In another embryo-fetal development study in pregnant rats, no structural abnormalities or embryocidal effects were seen at doses approximately 2 times the MRHDID (on a mcg/m 2 basis at maternal inhalation doses up to 250 mcg/kg/day). In a peri-and post-natal development study, rats dosed from gestation day 15 to postpartum day 21, budesonide had no effects on delivery, but did have an effect on growth and development of offspring. Offspring survival was reduced and surviving offspring had decreased mean body weights at birth and during lactation at doses less than 0.2 times the MRHDID and higher (on a mcg/m 2 basis at maternal subcutaneous doses of 20 mcg/kg/day and higher). These findings occurred in the presence of maternal toxicity. 8.2 Lactation Risk Summary There are no available data on the effects of PULMICORT RESPULES on the breastfed child or on milk production. Budesonide, like other inhaled corticosteroids, is present in human milk [see Data] . The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for PULMICORT RESPULES and any potential adverse effects on the breastfed infant from PULMICORT RESPULES or from the underlying maternal condition. Data Human data with budesonide delivered via dry powder inhaler indicates that the total daily oral dose of budesonide available in breast milk to the infant is approximately 0.3% to 1% of the dose inhaled by the mother [see Clinical Pharmacology (12.3) ] .

These findings occurred in the presence of maternal toxicity.
Pediatric use
8.4 Pediatric Use Safety and effectiveness in children six months to 12 months of age has been evaluated but not established. Safety and effectiveness in children 12 months to 8 years of age have been established [see Clinical Pharmacology (12.2) , Adverse Reactions (6.1) ] . A 12-week study in 141 pediatric patients 6 to 12 months of age with mild to moderate asthma or recurrent/persistent wheezing was conducted. All patients were randomized to receive either 0.5 mg or 1 mg of PULMICORT RESPULES or placebo once daily. Adrenal-axis function was assessed with an ACTH stimulation test at the beginning and end of the study, and mean changes from baseline in this variable did not indicate adrenal suppression in patients who received PULMICORT RESPULES versus placebo. However, on an individual basis, 7 patients in this study (6 in the PULMICORT RESPULES treatment arms and 1 in the placebo arm) experienced a shift from having a normal baseline stimulated cortisol level to having a subnormal level at Week 12 [see Clinical Pharmacology (12.2) ] . Pneumonia was observed more frequently in patients treated with PULMICORT RESPULES than in patients treated with placebo, (N = 2, 1, and 0) in the PULMICORT RESPULES 0.5 mg, 1 mg, and placebo groups, respectively. A dose dependent effect on growth was also noted in this 12-week trial. Infants in the placebo arm experienced an average growth of 3.7 cm over 12 weeks compared with 3.5 cm and 3.1 cm in the PULMICORT RESPULES 0.5 mg and 1 mg arms respectively. This corresponds to estimated mean (95% CI) reductions in 12-week growth velocity between placebo and PULMICORT RESPULES 0.5 mg of 0.2 cm (-0.6 to 1.0) and between placebo and PULMICORT RESPULES 1 mg of 0.6 cm (-0.2 to 1.4). These findings support that the use of PULMICORT RESPULES in infants 6 to 12 months of age may result in systemic effects and are consistent with findings of growth suppression in other studies with inhaled corticosteroids. Controlled clinical studies have shown that inhaled corticosteroids may cause a reduction in growth velocity in pediatric patients. In these studies, the mean reduction in growth velocity was approximately one centimeter per year (range 0.3 to 1.8 cm per year) and appears to be related to dose and duration of exposure. This effect has been observed in the absence of laboratory evidence of hypothalamic-pituitary-adrenal (HPA)-axis suppression, suggesting that growth velocity is a more sensitive indicator of systemic corticosteroid exposure in pediatric patients than some commonly used tests of HPA-axis function. The long-term effects of this reduction in growth velocity associated with orally inhaled corticosteroids, including the impact on final adult height, are unknown. The potential for “catch up” growth following discontinuation of treatment with orally inhaled corticosteroids has not been adequately studied. In a study of asthmatic children 5-12 years of age, those treated with budesonide administered via a dry powder inhaler 200 mcg twice daily (n=311) had a 1.1-centimeter reduction in growth compared with those receiving placebo (n=418) at the end of one year; the difference between these two treatment groups did not increase further over three years of additional treatment. By the end of four years, children treated with the budesonide dry powder inhaler and children treated with placebo had similar growth velocities. Conclusions drawn from this study may be confounded by the unequal use of corticosteroids in the treatment groups and inclusion of data from patients attaining puberty during the course of the study. The growth of pediatric patients receiving inhaled corticosteroids, including PULMICORT RESPULES, should be monitored routinely (e.g., via stadiometry). The potential growth effects of prolonged treatment should be weighed against clinical benefits obtained and the risks and benefits associated with alternative therapies. To minimize the systemic effects of inhaled corticosteroids, including PULMICORT RESPULES, each patient should be titrated to his/her lowest effective dose [see Dosage and Administration (2) , Warnings and Precautions (5.8) ] .
Geriatric use
8.5 Geriatric Use Of the 215 patients in 3 clinical trials of PULMICORT RESPULES in adult patients, 65 (30%) were 65 years of age or older, while 22 (10%) were 75 years of age or older. No overall differences in safety were observed between these patients and younger patients, and other reported clinical or medical surveillance experience has not identified differences in responses between the elderly and younger patients.
Overdosage
The potential for acute toxic effects following overdose of PULMICORT RESPULES is low. If inhaled corticosteroids are used at excessive doses for prolonged periods, systemic corticosteroid effects such as hypercorticism or growth suppression may occur [see Warnings and Precautions (5.6) ] .
Description
Budesonide, the active component of PULMICORT RESPULES ® , is a corticosteroid designated chemically as (RS)-11β, 16α, 17, 21-tetrahydroxypregna-1, 4-diene-3, 20-dione cyclic 16, 17-acetal with butyraldehyde. Budesonide is provided as a mixture of two epimers (22R and 22S). The empirical formula of budesonide is C 25 H 34 O 6 and its molecular weight is 430.5. Its structural formula is: Budesonide is a white to off-white, tasteless, odorless powder that is practically insoluble in water and in heptane, sparingly soluble in ethanol, and freely soluble in chloroform. Its partition coefficient between octanol and water at pH 7.4 is 1.6 x 10 3 . PULMICORT RESPULES is a sterile suspension for inhalation via jet nebulizer and contains the active ingredient budesonide (micronized), and the inactive ingredients disodium edetate, sodium chloride, sodium citrate, citric acid, polysorbate 80, and Water for Injection. Three dose strengths are available in single-dose ampules (Respules™ ampules): 0.25 mg, 0.5 mg, and 1 mg per 2 mL RESPULES ampule. For PULMICORT RESPULES, like all other nebulized treatments, the amount delivered to the lungs will depend on patient factors, the jet nebulizer utilized, and compressor performance. Using the Pari-LC-Jet Plus Nebulizer/Pari Master compressor system, under in vitro conditions, the mean delivered dose at the mouthpiece (% nominal dose) was approximately 17% at a mean flow rate of 5.5 L/min. The mean nebulization time was 5 minutes or less. PULMICORT RESPULES should be administered from jet nebulizers at adequate flow rates, via face masks or mouthpieces [see Dosage and Administration (2) ] . Chemical Structure for Pulmicort Respules
Mechanism of action
12.1 Mechanism of Action Budesonide is an anti-inflammatory corticosteroid that exhibits potent glucocorticoid activity and weak mineralocorticoid activity. In standard in vitro and animal models, budesonide has approximately a 200-fold higher affinity for the glucocorticoid receptor and a 1000-fold higher topical anti-inflammatory potency than cortisol (rat croton oil ear edema assay). As a measure of systemic activity, budesonide is 40 times more potent than cortisol when administered subcutaneously and 25 times more potent when administered orally in the rat thymus involution assay. The clinical significance of these findings is unknown. The activity of PULMICORT RESPULES is due to the parent drug, budesonide. In glucocorticoid receptor affinity studies, the 22R form was two times as active as the 22S epimer. In vitro studies indicated that the two forms of budesonide do not interconvert. The precise mechanism of corticosteroid actions on inflammation in asthma is not well known. Inflammation is an important component in the pathogenesis of asthma. Corticosteroids have been shown to have a wide range of inhibitory activities against multiple cell types (e.g., mast cells, eosinophils, neutrophils, macrophages, and lymphocytes) and mediators (e.g., histamine, eicosanoids, leukotrienes, and cytokines) involved in allergic- and non-allergic-mediated inflammation. The anti-inflammatory actions of corticosteroids may contribute to their efficacy in asthma. Studies in asthmatic patients have shown a favorable ratio between topical anti-inflammatory activities and systemic corticosteroid effects over a wide dose range of inhaled budesonide in a variety of formulations and delivery systems including an inhalation-driven, multi-dose dry powder inhaler and the inhalation suspension for nebulization. This is explained by a combination of a relatively high local anti-inflammatory effect, extensive first pass hepatic degradation of orally absorbed drug (85-95%) and the low potency of metabolites (see below).
How supplied
16 HOW SUPPLIED/STORAGE AND HANDLING PULMICORT RESPULES is supplied in sealed aluminum foil envelopes containing one plastic strip of five single-dose RESPULES ampules together with patient instructions for use. There are 30 RESPULES ampules in a carton. Each single-dose RESPULES ampule contains 2 mL of sterile liquid suspension. PULMICORT RESPULES is available in three strengths, each containing 2 mL: NDC 0186–1988–04 0.25 mg/2 mL NDC 0186–1989–04 0.5 mg/2 mL NDC 0186–1990–04 1 mg/2 mL PULMICORT RESPULES should be stored upright at controlled room temperature 20-25°C (68-77°F) [see USP], and protected from light. When an envelope has been opened, the shelf life of the unused RESPULES ampules is 2 weeks when protected. After opening the aluminum foil envelope, the unused RESPULES ampules should be returned to the aluminum foil envelope to protect them from light. Any opened RESPULES ampule must be used promptly. Gently shake the RESPULES ampule using a circular motion before use. Keep out of reach of children. Do not freeze.
Patient information
17.1 Administration with a Jet Nebulizer Patients should be advised that PULMICORT RESPULES should be administered with a jet nebulizer connected to a compressor with an adequate air flow, equipped with a mouthpiece or suitable face mask. Ultrasonic nebulizers are not suitable for the adequate administration of PULMICORT RESPULES and, therefore, are not recommended. The effects of mixing PULMICORT RESPULES with other nebulizable medications have not been adequately assessed. PULMICORT RESPULES should be administered separately in the nebulizer [see Dosage and Administration (2) ] . 17.2 Oral Candidiasis Patients should be advised that localized infections with Candida albicans occurred in the mouth and pharynx in some patients. If oropharyngeal candidiasis develops, it should be treated with appropriate local or systemic (i.e., oral) antifungal therapy while still continuing therapy with PULMICORT RESPULES, but at times therapy with PULMICORT RESPULES may need to be temporarily interrupted under close medical supervision. Rinsing the mouth after inhalation is advised [see Warnings and Precautions (5.1) ] . 17.3 Not for Acute Symptoms PULMICORT RESPULES is not meant to relieve acute asthma symptoms and extra doses should not be used for that purpose. Acute symptoms should be treated with an inhaled, short-acting beta 2 -agonist such as albuterol. (The healthcare professional should provide that patient with such medication and instruct the patient in how it should be used). Patients should be instructed to notify their healthcare professional immediately if they experience any of the following:
• Decreasing effectiveness of inhaled, short-acting beta 2 - agonists
• Need for more inhalations than usual of inhaled, short-acting beta 2 -agonists
• Significant decrease in lung function as outlined by the physician Patients should not stop therapy with PULMICORT RESPULES without physician/provider guidance since symptoms may recur after discontinuation [see Warnings and Precautions (5.2) ]. 17.4 Hypersensitivity Including Anaphylaxis Hypersensitivity reactions including anaphylaxis, rash, contact dermatitis, urticaria, angioedema, and bronchospasm have been reported with use of PULMICORT RESPULES. Discontinue PULMICORT RESPULES if such reactions occur [see Contraindications (4) , Warning and Precautions (5.3) ] . 17.5 Immunosuppression Patients who are on immunosuppressant doses of corticosteroids should be warned to avoid exposure to chickenpox or measles and, if exposed, to consult their physician without delay. If exposure to such a person occurs, and the child has not had chicken pox or been properly vaccinated, a physician should be consulted without delay. Patients should be informed of potential worsening of existing tuberculosis, fungal, bacterial, viral, or parasitic infections, or ocular herpes simplex [see Warnings and Precautions (5.4) ]. 17.6 Hypercorticism and Adrenal Suppression Patients should be advised that PULMICORT RESPULES may cause systemic corticosteroid effects of hypercorticism and adrenal suppression. Additionally, patients should be instructed that deaths due to adrenal insufficiency have occurred during and after transfer from systemic corticosteroids. Patients should taper slowly from systemic corticosteroids if transferring to PULMICORT RESPULES [see Warnings and Precautions (5.6) ] . 17.7 Reduction in Bone Mineral Density Patients who are at an increased risk for decreased BMD should be advised that the use of corticosteroids may pose an additional risk [see Warnings and Precautions (5.7) ] . 17.8 Reduced Growth Velocity Patients should be informed that orally inhaled corticosteroids, including PULMICORT RESPULES, may cause a reduction in growth velocity when administered to pediatric patients. Healthcare professionals should closely follow the growth of children and adolescents taking corticosteroids by any route [see Warnings and Precautions (5.8) ] . 17.9 Ocular Effects Long-term use of inhaled corticosteroids may increase the risk of some eye problems (cataracts or glaucoma); regular eye examinations should be considered [see Warnings and Precautions (5.9) ] . 17.10 Use Daily Patients should be advised to use PULMICORT RESPULES at regular intervals once or twice a day, since its effectiveness depends on regular use. Maximum benefit may not be achieved for 4 to 6 weeks or longer after starting treatment. If symptoms do not improve in that time frame or if the condition worsens, patients should be instructed to contact their healthcare professional. See accompanying Patient Information and Instructions for Use.
