Budesonide is available in various forms, such as inhalers for respiratory conditions, nasal sprays for rhinitis, and oral formulations for gastrointestinal issues, depending on the specific condition being treated.

Overall, (22R)-Budesonide is a versatile anti-inflammatory agent that plays a crucial role in managing various chronic inflammatory conditions, improving the quality of life for patients.
