Q:Do you have a formula for compounding budesonide inhalation?

A:Budesonide suspension for inhalation (0.25 mg/2 mL and 0.5 mg/2 mL) is available as a commercially prepared, preserved, FDA-approved finished drug product. The compounding pharmacist should review and document factors that will support compounding of a similar formulation for each patient-specific order, request, or prescription. Examples of such factors include patient intolerance to an ingredient in the commercially prepared product, shortages or temporary unavailability, or discontinuance of the product.
