Aim. To develop the composition and technology for obtaining the combined drug of indapamide with enalapril of the prolonged action.
Materials and methods. Indapamide and enalapril maleate substances as active components, and polyvinylpyrrolidone, calcium stearate, lactose monohydrate, hydroxypropyl methylcellulose as excipients were used. The pharmaco-
technological studies were conducted according to the methods of the State Pharmacopoeia of Ukraine (SPhU).
Results and discussion. The pharmaco-technological properties of tablet mixtures and the quality of finished tablets were compared using direct pressing and preliminary wet granulation.
Conclusions. It has been found that the use of the method of pre-granulation of the tablet mixture allows obtaining a finished product that fully meets the requirements of the SPhU.
