Budesonide (BUD), sold under the brand name Pulmicort among others, is a medication of the corticosteroid type.[1] It is available as an inhaler, pill, nasal spray, and rectal forms.[1][2] The inhaled form is used in the long-term management of asthma and chronic obstructive pulmonary disease(COPD).[1][7][8] The nasal spray is used for allergic rhinitis and nasal polyps.[2][9] The pills in a delayed release form and rectal forms may be used for inflammatory bowel disease including Crohn's disease, ulcerative colitis and microscopic colitis.[3][10][11]

Common side effects with the inhaled form include respiratory infections, cough, and headaches.[1] Common side effects with the pills include feeling tired, vomiting, and joint pains.[1] Serious side effects include an increased risk of infection, loss of bone strength, and cataracts.[1] Long-term use of the pill form may cause adrenal insufficiency.[1] Stopping the pills suddenly following long-term use may therefore be dangerous.[1] The inhaled form is generally safe in pregnancy.[1] Budesonide is mainly acting as a glucocorticoid.[1]

Budesonide was initially patented in 1973.[12] Commercial use as an asthma medication began in 1981.[13] It is on the World Health Organization's List of Essential Medicines.[14] Some forms are available as a generic medication.[15] The wholesale price in the developing world for an inhaler containing 200 doses is about US$5 to US$7 as of 2014.[16] As of 2015, the cost for a typical month of the inhaler medication in the United States is US$100 to US$200.[15] In 2019, generic budesonide was listed as involved in Teva's price fixing scheme in the USA.[17] In 2017, it was the 190th most commonly prescribed medication in the United States, with more than three million prescriptions.[18][19]

Medical uses


Budesonide is given by metered-dose inhaler or nebulizer for maintenance and prophylactic treatment of asthma including patients who require oral corticosteroids and those who may benefit from a systemic dose reduction.[20]

Inflammatory bowel disease

Formulations of delayed-release budesonide are an effective treatment for mild-to-moderately active Crohn's disease involving the ileum and/or ascending colon.[21] A Cochrane review found evidence for up to three months (but not longer) of maintenance of remission in Crohn's disease.[22]

Budesonide assists in the induction of remission in people with active ulcerative colitis.[23]

Budesonide is highly effective and recommended as the drug of choice in microscopic colitis, for induction and maintenance of remission, and for both the lymphocytic colitis and collagenous colitis forms.[24]

Allergic rhinitis

Budesonide in the form of nasal sprays is a treatment for allergic rhinitis.[25]

Eosinophilic esophagitis

Topical budesonide has considerable effects in eosinophilic esophagitis.[26] For this use, it is formulated as a tablet that disperses in the mouth and sold under the trade name Jorveza.[27]


The defined daily dose is 0.8 mg (inhalation aerosol) or 0.8 mg (inhalation powder) or 1.5 mg (inhalation solution) for asthma[4] and 0.2 mg (nasal) [5] and 9 mg (by mouth).[6]

Side effects

Budesonide may cause:[28]

  • Nose irritation or burning
  • Bleeding or sores in the nose
  • Lightheadedness
  • Upset stomach
  • Cough
  • Hoarseness
  • Dry mouth
  • Rash
  • Sore throat
  • Bad taste in mouth
  • Change in mucus
  • Blurred vision [29]

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)[28]


Budesonide is contraindicated as a primary treatment of status asthmaticus or other acute episode of asthma where intensive measures are required.[30] It is also contraindicated for patients who have hypersensitivity to budesonide.[31]


Those taking tablets or capsules orally should avoid grapefruit juice and echinacea.[medical citation needed]

Also, high-fat meals delay absorption but do not impede absorption.[medical citation needed]


Budesonide is an agonist of glucocorticoid receptors. Among its effects are:[citation needed]

  • 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.[medical citation needed]


  • Onset of action: Nebulization: 2–8 days; Inhalation: 24 hours; Nasal: 10 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.[medical citation needed]


Budesonide, also known as 11β,21-dihydroxy-16α,17α-(butylidenebis(oxy))pregna-1,4-diene-3,20-dione, is a synthetic pregnane steroid and non-halogenated cyclic ketal corticosteroid.[32][33] It is the C16α hydroxyl, C16α,17α cyclic ketal with butyraldehyde derivative of prednisolone (11β,17α,21-trihydroxypregna-1,4-diene-3,20-dione).[32][33]

Society and culture


The wholesale price in the developing world for an inhaler containing 200 doses is about US$5 to US$7 as of 2014.[16] As of 2015, the cost for a typical month of the inhaler medication in the United States is US$100 to US$200.[15] In 2017, it was the 190th most commonly prescribed medication in the United States, with more than three million prescriptions.[18][19]

During the 2020 pandemic, doctors and researchers observed that patients already prescribed inhaled corticosteroids appeared to develop less serious illness when diagnosed with COVID-19, despite often having conditions such as asthma that might be thought to lead to more serious illness.[34][35] Subsequently, the drug was explored as a possible treatment for the disease.[36] In June 2020, UK and Australian researchers began a UK-based trial of budesonide as an early-intervention treatment for COVID-19, with results expected in September of that year.[37]
