Budesonide is a corticosteroid widely used to treat inflammatory respiratory, digestive, and nasal diseases. Its clinical efficacy is well established, and its safety profile depends on the mode of administration and duration of treatment.
Medical uses and presentations
In its inhaled form, budesonide is a key drug in the management of asthma. It is also used in the treatment of chronic obstructive pulmonary disease (COPD) in selected patients with frequent exacerbations and/or a suitable inflammatory profile.
Budesonide reduces inflammation of the bronchi and improves respiratory function, acting differently from bronchodilator medications such as Fluidasa, which relax the bronchial muscles.
It is also used as a nasal spray to treat seasonal and perennial allergic rhinitis and nasal polyps. In modified-release capsules, it is indicated for the treatment of inflammatory bowel diseases such as Crohn's disease, ulcerative colitis, and microscopic colitis.
Budesonide is available in dry powder inhalers, nebulizer suspension, oral capsules, and nasal sprays. The choice depends on the patient's diagnosis and age.
Dosage and administration
The inhaled dose varies between 0.25 mg and 2 mg per day, adjusted according to the severity and response of the patient. In adults with moderate asthma, a daily dose of between 0.5 mg and 1 mg is recommended, administered once or twice daily.
For the treatment of active Crohn's disease, 9 mg of oral budesonide is recommended daily. Treatment should be maintained for a limited period, generally no longer than eight weeks. In the case of microscopic colitis, the initial dose may be reduced once the patient shows improvement.
On the other hand, for nasal administration, one or two sprays are applied to each nostril daily. It is important to tilt your head slightly forward during use and avoid contact with the eyes.
Common side effects
With inhaled use, throat irritation, hoarseness, a dry cough, or oral candidiasis may occur. These discomforts are minimized if the patient rinses their mouth with water after each dose.
With prolonged treatment, especially at high doses, there is a risk of systemic effects such as glaucoma, cataracts, decreased bone density, or adrenal suppression.
Oral budesonide may cause abdominal pain, nausea, headache, or fatigue. Less commonly, insomnia, anxiety, or increased blood pressure have been reported. Children and adolescents require special monitoring due to possible growth retardation with prolonged use.
Recommendations and precautions
This drug should always be used under medical supervision and at the lowest effective dose for the shortest possible duration. It should not be discontinued abruptly if it has been used for several consecutive weeks.
It is contraindicated in patients with untreated fungal, viral, or bacterial infections. People with liver disease, ulcers, osteoporosis, or eye conditions should exercise special caution.
During pregnancy and breastfeeding, its use should be carefully considered. Budesonide crosses the placenta, but studies using inhalers have not shown significant adverse effects.
Conclusion
Budesonide is a locally acting corticosteroid with proven benefits in chronic inflammatory diseases. Its effectiveness depends on proper, regular, and controlled use. With correct indication and medical supervision, its use can substantially improve the quality of life of people with asthma, rhinitis, Crohn's disease and other inflammatory conditions.
