Budesonide
Absorption: Unknown.
Distribution: Extensively distributed to extravascular tissues.
Metabolism/Excretion: Primarily metabolized by the liver by the CYP3A4 isoenzyme into inactive metabolites; primarily excreted in urine and feces as metabolites.
Half-Life: 5 hr.
Formoterol
Absorption: Unknown.
Distribution: Extensively distributed to extravascular tissues.
Metabolism/Excretion: Primarily metabolized by the liver by glucuronidation and O-demethylation to inactive metabolites; 62% of drug excreted in urine, 24% excreted in feces.
Half-Life: 10 hr.
Glycopyrrolate
Absorption: Unknown.
Distribution: Extensively distributed to extravascular tissues.
Metabolism/Excretion: Primarily metabolized by the liver, with the CYP2D6 isoenzyme playing a minor role in elimination; 85% excreted in urine.
Half-Life: 15 hr.
Contraindicated in:
- Hypersensitivity;
- Asthma;
- Acutely deteriorating COPD or acute respiratory symptoms.
Use Cautiously in:
- Systemic corticosteroid therapy (should not be abruptly discontinued when inhaled therapy is started; additional corticosteroids needed during stress or trauma);
- Prolonged immobilization, family history of osteoporosis, postmenopausal status, cigarette smoking, advanced age, or poor nutrition (↑ risk of osteoporosis);
- Narrow-angle glaucoma;
- Seizure disorders;
- Thyrotoxicosis;
- Urinary retention, prostatic hyperplasia, bladder-neck obstruction;
- Diabetes;
- Severe hepatic impairment;
- Severe renal impairment (CCr <30 mL/min) or end-stage renal disease requiring dialysis (use only if expected benefit exceeds potential risk);
- OB: Safety not established in pregnancy;
- Lactation: Use while breastfeeding only if potential maternal benefit justifies potential risk to infant;
- Pedi: Safety and effectiveness not established in children.
Exercise Extreme Caution in:
- Concurrent use of MAO inhibitors, tricyclic antidepressants, or drugs that prolong the QTc interval.
