Cyclodextrin-Based Inclusion Complexes Improve the In Vitro Solubility and Pharmacokinetics of Ivacaftor Following Oral Administration in Mice.

ABSTRACT: Cystic fibrosis is a serious life-threatening hereditary disease that occurs due to a mutation in the cystic fibrosis transmembrane conductance regulator gene (CFTR). Ivacaftor (IVA) is a drug that targets the mutated CFTR protein. IVA is highly hydrophobic (log P = 5.6) with poor aqueous solubility (0.05 µg/mL) and is formulated as an amorphous solid dispersion tablet under the brand name Kalydeco^®. The recommended daily dose of Kalydeco^® is twice per day with a high fat meal to aid in IVA's absorption. In this research, we studied the application of cyclodextrins (CDs) to improve the dissolution of IVA. Phase solubility studies between IVA and four different CDs (α-, β-, γ-, and hydroxypropyl-β-CD [HP-β-CD]) were conducted and a significant improvement in IVA's aque
