Olfosonide (Budesonide)

Budesonide acts on inflammatory pathways in the respiratory and gastrointestinal systems.

• Asthma: helps reduce the frequency of bronchial constriction episodes.
• Chronic obstructive pulmonary disease (COPD): contributes to improved lung function and symptom control.
• Allergic rhinitis: alleviates nasal congestion and sneezing.
• Inflammatory bowel disease (IBD): supports remission of colonic inflammation.
• Eosinophilic esophagitis: reduces esophageal eosinophil counts and dysphagia.
• Nasal polyps: shrinks polyp size and improves nasal airflow .

• Budesonide binds selectively to glucocorticoid receptors in the cytoplasm, forming a complex that translocates to the nucleus. This complex interacts with glucocorticoid response elements, modulating gene transcription to suppress pro‑inflammatory cytokines, inhibit leukocyte migration, and reduce vascular permeability, thereby providing anti‑inflammatory and immunosuppressive effects.

Budesonide may cause a range of adverse reactions, from mild to severe.

Common Side Effects

• Oral thrush: fungal overgrowth in the mouth.
• Hoarseness: voice changes due to local irritation.
• Cough: transient irritation of the airway.
• Headache: mild, non‑specific headache.
• Nasal irritation: dryness or burning sensation.
• Nausea: mild gastrointestinal upset.

Serious or Rare Side Effects

• Adrenal suppression: reduced endogenous cortisol production.
• Severe fungal infection: systemic candidiasis.
• Glaucoma or cataract formation: increased intra‑ocular pressure.
• Osteoporosis: decreased bone mineral density with long‑term use.
• Hypersensitivity reactions: rash, urticaria, anaphylaxis.
• Pneumonia: increased risk of lower respiratory infection.

When using Budesonide, several safety considerations should be observed.

• Monitor adrenal function: assess cortisol levels in long‑term therapy.
• Evaluate infection risk: watch for signs of fungal or bacterial infections.
• Use lowest effective dose: minimize systemic exposure.
• Counsel on proper inhaler technique: reduce oropharyngeal deposition.
• Review bone health: consider calcium/vitamin D supplementation if therapy exceeds 3 months.
• Store at ambient temperature: keep in original container, protect from moisture and direct sunlight.

Budesonide can interact with several drug classes, affecting its efficacy or safety.

Major Interactions (Avoid)

• Strong CYP3A4 inhibitors: e.g., ketoconazole, itraconazole, may increase systemic exposure.
• Systemic immunosuppressants:  
• Antifungal
