Pharmacology

Controls the rate of protein synthesis; depresses the migration of polymorphonuclear leukocytes, fibroblasts; reverses capillary permeability and lysosomal stabilization at the cellular level to prevent or control inflammation

Absorption

Readily; quickly hydrolyzed by pulmonary esterases to active metabolite (beclomethasone-17-monoproprionate [17-BMP]) during absorption

Distribution

Vd: Beclomethasone dipropionate (BDP): 20 L; 17-BMP: 424 L

Metabolism

BDP is a pro-drug (inactive); undergoes rapid conversion to 17-BMP during absorption; followed by additional metabolism via CYP3A4 to other, less active metabolites (beclomethasone-21-monopropionate [21-BMP] and beclomethasone [BOH])

Excretion

Primary route of excretion is via feces (~60%); <10% to 12% of oral dose excreted in urine as metabolites

Onset of Action

Within 1 to 2 days in some patients; usually within 1 to 2 weeks; Maximum effect: 3 to 4 weeks

Time to Peak

Plasma: Oral inhalation: BDP: 0.5 hours; 17-BMP: 0.7 hours

Half-Life Elimination

BDP: 0.5 hours; 17-BMP: 2.7 hours

Protein Binding

BDP 87%; 17-BMP: 94% to 96%

Use: Labeled Indications

Asthma: Maintenance and prophylactic treatment of asthma in patients ≥5 years (including those who require corticosteroids and those who may benefit from a dose reduction/elimination of systemically administered corticosteroids).

Limitations of use: Not for relief of acute bronchospasm.

Guideline recommendations: A low-dose inhaled corticosteroid (in addition to an as-needed short acting beta2-agonist) is the initial preferred long-term control medication for children, adolescents, and adult patients with persistent asthma who are candidates for treatment according to a step-wise treatment approach (GINA 2016; NAEPP 2007).

Contraindications

Hypersensitivity to beclomethasone or any component of the formulation; status asthmaticus, or other acute asthma episodes requiring intensive measures

Documentation of allergenic cross-reactivity for corticosteroids is limited. However, because of similarities in chemical structure and/or pharmacologic actions, the possibility of cross-sensitivity cannot be ruled out with certainty.

Canadian labeling: Additional contraindications (not in US labeling): Moderate to severe bronchiectasis requiring intensive measures; untreated fungal, bacterial, or tubercular infections of the respiratory tract

Dosing: Adult

Asthma: Inhalation, oral (doses should be titrated to the lowest effective dose once asthma is controlled):

US labeling:

Patients previously on bronchodilators only: Initial dose 40 to 80 mcg twice daily; maximum dose: 320 mcg twice daily

Patients previously on inhaled corticosteroids: Initial dose 40 to 160 mcg twice daily; maximum dose: 320 mcg twice daily

Canadian labeling:

Mild asthma: 50 to 100 mcg twice daily; maximum dose: 100 mcg twice daily

Moderate asthma: 100 to 250 mcg twice daily; maximum dose: 250 mcg twice daily

Severe asthma: 300 to 400 mcg twice daily; maximum dose: 400 mcg twice daily

Asthma Guidelines:

National Asthma Education and Prevention Program guidelines (NAEPP 2007): HFA inhaler (refers to Qvar 40 mcg and 80 mcg strengths available in US):

“Low” dose: 80 to 240 mcg daily

“Medium” dose: >240 to 480 mcg daily

“High” dose: >480 mcg daily

Global Initiative for Asthma guidelines (GINA 2016): HFA inhaler (refers to Qvar 50 mcg and 100 mcg strengths available in Canada):

“Low” dose: 100 to 200 mcg daily

“Medium” dose: >200 to 400 mcg daily

“High” dose: >400 mcg daily

Conversion: Conversion from oral systemic corticosteroid to orally inhaled corticosteroid: Initiation of oral inhalation therapy should begin in patients whose asthma is reasonably stabilized on oral corticosteroids (OCS). A gradual dose reduction of OCS should begin ~7 days after starting inhaled therapy. US labeling recommends reducing prednisone dose no more rapidly than ≤2.5 mg/day (or equivalent of other OCS) every 1 to 2 weeks. The Canadian labeling recommends decreasing the daily dose of prednisone by 1 mg (or equivalent of other OCS) every 7 days or more in closely monitored patients. If adrenal insufficiency occurs, temporarily increase the OCS dose and follow with a more gradual withdrawal. Note: When transitioning from systemic to inhaled corticosteroids, supplemental systemic corticosteroid therapy may be necessary during periods of stress or during severe asthma attacks.

Chronic obstructive pulmonary disease (stable) (off-label use): Inhalation, oral: 50 to 400 mcg daily in combination with a long-acting bronchodilator (GOLD, 2014).

Administration

Canister does not need shaken prior to use. Prime canister by spraying twice into the air prior to initial use or if not in use for >10 days. Avoid spraying in face or eyes. Exhale fully prior to bringing inhaler to mouth. Place inhaler in mouth, close lips around mouthpiece, and inhale slowly and deeply. Remove inhaler and hold breath for approximately 5 to 10 seconds. Rinse mouth and throat with water (and spit) after use to prevent Candida infection. Do not wash or put inhaler in water; mouth piece may be cleaned with a dry tissue or cloth. Discard the inhaler when the dose counter displays "0". Patients using a spacer should inhale immediately due to decreased amount of medication that is delivered with a delayed inspiration.

Storage

Store at 25°C (77°F); excursions are permitted between 15°C and 30°C (59°F and 86°F). Do not use or store near heat or open flame. Do not puncture canisters. Store on concave end of canister with actuator on top.

Warnings/Precautions

Concerns related to adverse effects:

• Adrenal suppression: May cause hypercorticism or suppression of hypothalamic-pituitary-adrenal (HPA) axis, particularly in younger children or in patients receiving high doses for prolonged periods. HPA axis suppression may lead to adrenal crisis. Withdrawal and discontinuation of a corticosteroid should be done slowly and carefully. Particular care is required when patients are transferred from systemic corticosteroids to inhaled products due to possible adrenal insufficiency or withdrawal from steroids, including an increase in allergic symptoms. Patients receiving >20 mg per day of prednisone (or equivalent) may be most susceptible. Fatalities have occurred due to adrenal insufficiency in asthmatic patients during and after transfer from systemic corticosteroids to aerosol steroids; aerosol steroids do not provide the systemic steroid needed to treat patients having trauma, surgery, or infections (particularly gastroenteritis), or other conditions with severe electrolyte loss. Select surgical patients on long-term, high-dose, inhaled corticosteroid (ICS), should be given stress doses of hydrocortisone intravenously during the surgical period and the dose reduced rapidly within 24 hours after surgery (Expert Panel Report 3, 2007).

• Bronchospasm: May occur with wheezing after inhalation (possibly life-threatening); if bronchospasm occurs, discontinue steroid and treat with a fast-acting bronchodilator.

• Hypersensitivity reactions: Immediate hypersensitivity reactions may occur, including angioedema, bronchospasm, rash, and urticaria; discontinue use if reaction occurs.

• Immunosuppression: Prolonged use of corticosteroids may also increase the incidence of secondary infection, mask acute infection (including fungal infections), prolong or exacerbate viral infections, or limit response to vaccines. Avoid use, if possible, in patients with ocular herpes, active or quiescent respiratory tuberculosis, or untreated viral, fungal, parasitic or bacterial systemic infections (Canadian labeling contraindicates use with untreated respiratory infections). Exposure to chickenpox and measles should be avoided. Close observation is required in patients with latent tuberculosis and/or TB reactivity.

• Kaposi sarcoma: Prolonged treatment with corticosteroids has been associated with the development of Kaposi sarcoma (case reports); if noted, discontinuation of therapy should be considered.

• Oral candidiasis: Candida albicans infections may occur in the mouth and pharynx; rinsing (and spitting) with water after inhaler use may decrease risk.

• Psychiatric disturbances: Corticosteroid use may cause psychiatric disturbances, including depression, euphoria, insomnia, mood swings, and personality changes. Preexisting psychiatric conditions may be exacerbated by corticosteroid use.

• Vasculitis: Rare cases of vasculitis (Churg-Strauss syndrome) or other systemic eosinophilic conditions can occur; often associated with decrease and/or withdrawal of oral corticosteroid therapy following initiation of inhaled corticosteroid.

Disease-related concerns:

• Asthma: Supplemental steroids (oral or parenteral) may be needed during stress or severe asthma attacks. Not to be used in status asthmaticus or for the relief of acute bronchospasm.

• Bone mineral density: Use with caution in patients with major risk factors for decreased bone mineral count such as prolonged immobilization, family history of osteoporosis, postmenopausal status, tobacco use, advanced age, poor nutrition, or chronic use of drugs that can reduce bone mass (eg, anticonvulsants, oral corticosteroids); long-term use of inhaled corticosteroids have been associated with decreases in bone mineral density.

• Cardiovascular disease: Use with caution in patients with HF; long-term corticosteroid use has been associated with fluid retention and hypertension.

• Diabetes: Use with caution in patients with diabetes mellitus; corticosteroids may alter glucose production/regulation leading to hyperglycemia.

• Gastrointestinal disease: Use corticosteroids with caution in patients with GI diseases (diverticulitis, peptic ulcer, ulcerative colitis) due to perforation risk.

• Hepatic impairment: Use with caution in patients with hepatic impairment, including cirrhosis; long-term corticosteroid use has been associated with fluid retention.

• Myasthenia gravis: Use with caution in patients with myasthenia gravis; exacerbation of symptoms has occurred especially during initial treatment with corticosteroids.

• Myocardial infarct (MI): Use with caution following acute MI; corticosteroids have been associated with myocardial rupture.

• Ocular disease: Use with caution in patients with cataracts and/or glaucoma; increased intraocular pressure, glaucoma, and cataracts have occurred (rarely) with oral inhalation of corticosteroids.

• Renal impairment: Use with caution in patients with renal impairment; fluid retention may occur with long-term corticosteroid use.

• Seizure disorders: Use with caution in patients with a history of seizure disorder; seizures have been reported with adrenal crisis.

• Thyroid disease: Changes in thyroid status may necessitate dosage adjustments; metabolic clearance of corticosteroids increases in hyperthyroid patients and decreases in hypothyroid ones.

Special populations:

• Pediatric: Orally inhaled corticosteroids may cause a reduction in growth velocity in pediatric patients (~1 centimeter per year [range: 0.3 to 1.8 cm per year] and related to dose and duration of exposure). To minimize the systemic effects of orally inhaled corticosteroids, each patient should be titrated to the lowest effective dose. Growth should be routinely monitored in pediatric patients.

Other warnings/precautions:

• Discontinuation of therapy: A gradual tapering of dose may be required prior to discontinuing therapy; there have been reports of systemic corticosteroid withdrawal symptoms (eg, joint/muscle pain, lassitude, depression) when withdrawing oral inhalation therapy.

• Transfer to oral inhaler: When transferring to oral inhalation therapy from systemic corticosteroid therapy; previously suppressed allergic conditions (rhinitis, conjunctivitis, eczema, arthritis, and eosinophilic conditions) may be unmasked. Withdraw systemic therapy with gradual tapering of dose; during transition monitor pulmonary function tests (FEV1 or PEF), beta-agonist use, and asthma symptoms and observe for signs and symptoms of adrenal insufficiency (eg, fatigue, lassitude, weakness, nausea/vomiting, hypotension).

Monitoring Parameters

Growth (adolescents) and signs/symptoms of HPA axis suppression/adrenal insufficiency; signs/symptoms of oral candidiasis; ocular effects (eg, cataracts, increased intraocular pressure, glaucoma)

Pregnancy Risk Factor

C

Pregnancy Considerations

Adverse events have been observed in animal reproduction studies. Hypoadrenalism may occur in newborns following maternal use of corticosteroids in pregnancy. Based on available data, an overall increased risk of congenital malformations or a decrease in fetal growth has not been associated with maternal use of inhaled corticosteroids during pregnancy (Bakhireva, 2005; NAEPP, 2005; Namazy, 2004). Uncontrolled asthma is associated with adverse events in pregnancy (increased risk of perinatal mortality, pre-eclampsia, preterm birth, low birth weight infants). Inhaled corticosteroids are recommended for the treatment of asthma during pregnancy (most information available using budesonide) (ACOG, 2008; NAEPP, 2005).

Patient Education

• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

• Patient may experience headache, rhinitis, or pharyngitis. Have patient report immediately to prescriber signs of infection, thrush, severe loss of strength and energy, irritability, tremors, tachycardia, confusion, dizziness, difficulty breathing, wheezing, cough, or sweating (HCAHPS).

• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
