The local versus total systemic availability (L/T-ratio) can be used to express the effectiveness of the inhaled formulation. 2021-09-18T02:12:28-07:00 The nasal spray is used for allergic rhinitis and nasal polyps. To confirm that systemic absorption is not a significant factor in the clinical efficacy of inhaled budesonide, a clinical study in adult patients with asthma was performed comparing 400 mcg budesonide administered via a pressurized metered dose inhaler with a tube spacer to 1400 mcg of oral budesonide and placebo. Budesonide inhalation powder has clinical efficacy equivalent to that of fluticasone and beclomethasone, but it has lower systemic bioavailability and fewer systemic side effects.

After inhalation, a large part (approximately 40–90%) of the dose is swallowed and subsequently available for systemic absorption.

Br J Clin Pharmacol 2006;62:412–19.. By comparison, high-dose inhaled budesonide caused up to 73% suppression of plasma cortisol in the present study, confirming that the systemic effect is mostly due to pulmonary, not GI, absorption. inhaled drugs reach systemic circulation either by direct absorption through the lungs or via gastrointestinal absorption of the drug when it is inadvertently swallowed [19,20]. Bioavailability profile of Uceris MMX extended-release tablets compared with Entocort EC capsules in healthy volunteers. Food appears to have little impact on the absorption of budesonide from Entocort EC capsules and the pharmacokinetics are dose-proportional between 3 and 15 mg.
