|(what is this?)|
Budesonide is a glucocorticoid steroid for the treatment of asthma, COPD and non-infectious rhinitis (including hay fever and other allergies), and for treatment and prevention of nasal polyposis. In addition, it is used for Crohn's disease (inflammatory bowel disease).
It is on the World Health Organization's List of Essential Medicines, a list of the most important medication needed in a basic health system.
Treatment of active Crohn's disease involving the ileum and/or ascending colon; maintenance of remission (for up to 3 months) of Crohn's disease (mild-to-moderate) involving the ileum and/or ascending colon.
Budesonide assists in the induction of remission in patients with active ulcerative colitis.
Budesonide may cause:
- Nose irritation or burning
- Bleeding or sores in the nose
- Upset stomach
- Dry mouth
- Sore throat
- Bad taste in mouth
- Change in mucus color
- Muscle cramps
In addition, the following symptoms should be reported immediately:
- Difficulty breathing or swelling of the face
- White patches in the throat, mouth, or nose
- Irregular menstrual periods
- Severe acne
- On rare occasions, behavioral changes (mostly affecting children)
Budesonide is contraindicated as a primary treatment of status asthmaticus or other acute episode of asthma where intensive measures are required. It is also contraindicated for patients who have hypersensitivity to budesonide.
Mechanism of action
- Controls the rate of protein synthesis.
- Depresses the migration of polymorphonuclear leukocytes and fibroblasts.
- Reverses capillary permeability and lysosomal stabilization at the cellular level to prevent or control inflammation.
- Has a potent glucocorticoid activity and weak mineralocorticoid activity.
Those taking tablets or capsules orally should avoid grapefruit juice and echinacea.
- Grapefruit juice may double bioavailability of oral budesonide.
- Echinacea diminishes bioavailability.
Also, high fat meals delay absorption but do not impede absorption.
- Onset of action: Nebulization: 2-8 days; Inhalation: 24 hours
- Peak effect: Nebulization: 4-6 weeks; Inhalation: 1-2 weeks
- Distribution: 2.2-3.9 L/kg
- Protein binding: 85% to 90%
- Metabolism: Hepatic via CYP3A4 to two metabolites: 16 alpha-hydroxyprednisolone and 6 beta-hydroxybudesonide; minor activity
- Bioavailability: Limited by high first-pass effect; Capsule: 9% to 21%; Nebulization: 6%; Inhalation: 6% to 13%
- Half-life elimination: 2-3.6 hours
- Time to peak: Capsule: 0.5-10 hours (variable in Crohn's disease); Nebulization: 10-30 minutes; Inhalation: 1-2 hours; Tablet: 7.4-19.2 hours
- Excretion: Urine (60%) and feces as metabolites.
