Budesonide is a white to off-white, tasteless, odorless powder that is practically insoluble in water and in heptane, sparingly soluble in ethanol, and freely soluble in chloroform. Its partition coefficient between octanol and water at pH 7.4 is 1.6 x 103.
PULMICORT RESPULES (budesonide inhalation suspension) is a sterile suspension for inhalation via jet nebulizer and contains the active ingredient budesonide (micronized), and the inactive ingredients disodium edetate, sodium chloride, sodium citrate, citric acid, polysorbate 80, and Water for Injection. Three dose strengths are available in single-dose ampules (Respules™ ampules): 0.25 mg, 0.5 mg, and 1 mg per 2 mL RESPULES ampule. For PULMICORT RESPULES (budesonide inhalation suspension) , like all other nebulized treatments, the amount delivered to the lungs will depend on patient factors, the jet nebulizer utilized, and compressor performance. Using the Pari-LC-Jet Plus Nebulizer/Pari Master compressor system, under in vitro conditions, the mean delivered dose at the mouthpiece (% nominal dose) was approximately 17% at a mean flow rate of 5.5 L/min. The mean nebulization time was 5 minutes or less. PULMICORT RESPULES should be administered from jet nebulizers at adequate flow rates, via face masks or mouthpieces [see DOSAGE AND ADMINISTRATION].
