In the solid, inclusion complex was prepared by freezed drying method. The inclusion complex formed was characterized, compared with phenobarbital, hydroxypropyl-β-cyclodextrine, and the physical mixture of phenobarbital and hydroxypropyl-β-cyclodextrine.
Analyses using DSC and X-ray diffractometry showed that phenobarbital formed inclusion complex with hydroxypropyl-β-cyclodextrine.
