Budesonide
Budesonide is a corticosteroid formulated for more than one route in the body. MedlinePlus explains that inhaled budesonide is used to prevent difficulty breathing, chest tightness, wheezing and coughing caused by asthma, working by reducing swelling and irritation in the airways. Budecort Inhaler supplies budesonide alone, Foracort Inhaler pairs it with the bronchodilator formoterol, and Budez CR is a delayed-release capsule.

Foracort Inhaler
Asthma, Chronic Obstructive Pulmonary Disease

Formulated to alleviate bronchial constrictions to support steady respiration and target mucosal tissue swelling.
Key points
- Inhaled budesonide helps prevent asthma attacks but will not stop one that has already started; a fast-acting rescue inhaler is needed for that.
- The DailyMed capsule label lists mild to moderate active Crohn’s disease involving the ileum and the ascending colon as an indication for the delayed-release capsule.
How the delayed-release capsule is built, and how the body clears it
Budesonide delayed-release capsules are hard gelatin capsules filled with enteric-coated granules that dissolve above pH 5.5; Budez CR is this formulation. Once absorbed, budesonide is metabolised mainly by the CYP3A4 enzyme into two major metabolites, 6-beta-hydroxy budesonide and 16-alpha-hydroxy prednisolone.
Corticosteroid safety across both routes
Corticosteroids including budesonide can cause hypercorticism and suppress the adrenal axis, and the label asks prescribers to monitor for both during treatment. Corticosteroid-related immune suppression also raises the risk of viral, bacterial, fungal, protozoal and helminthic infections, including potentially fatal varicella and measles.
Budesonide is also known regionally as Pulmicort Turbuhaler, an inhaled budesonide brand named in the Emirates Drug Establishment product directory.
