Thank you for your inquiry.
Should you choose to treat your patient with a swallowed topical steroid, my choice would be budesonide. Fluticasone is classified as a Class C drug in pregnancy whereas budesonide is a Class B drug. Also, budesonide slurries have been shown to be effective (see abstract below). Finally, budesonide has an extensive first pass metabolism when administered orally (85 to 95%), making it comparable to fluticasone in this regard.
Thank you again for your inquiry and we hope this response is helpful to you.
Viscous Topical Is More Effective Than Nebulized Steroid Therapy for Patients With Eosinophilic Esophagitis
Volume 143, Issue 2, August 2012, Pages 321–324.e1
We performed a randomized trial to compare nebulized and viscous topical corticosteroid treatments for eosinophilic esophagitis (EoE). Subjects with incident EoE (n = 25) received budesonide 1 mg twice daily, either nebulized and then swallowed (NEB) or as an oral viscous slurry (OVB), for 8 weeks. Baseline eosinophil counts for the NEB and OVB groups were 101 and 83 (P = .62). Posttreatment counts were 89 and 11 (P = .02). The mucosal medication contact time, measured by scintigraphy, was higher for the OVB group than the NEB group (P < .005) and was inversely correlated with eosinophil count (R = −0.67; P = .001). OVB was more effective than NEB in reducing numbers of esophageal eosinophils in patients with EoE. OVB provided a significantly higher level of esophageal exposure to the therapeutic agent, which correlated with lower eosinophil counts.
