Enalapril:β-CD complex: Stability enhancement in solid state

► Enalapril maleate:β-cyclodextrin complexation in solid state was studied. ► The complex particles were characterized by SSNMR, SEM and XRPD. ► Results of solid-state analysis revealed that the complex is a new amorphous solid. ► The compatibility between enalapril maleate with magnesium stearate was evaluated. ► Enalapril maleate in the complex form was more stable than the drug alone.
