Stable solid compositions comprising quinapril magnesium can be made using quinapril or an acid addition salt thereof, by reacting the quinapril or acid addition salt with an alkaline magnesium compound in the prsence of a solvent, so as to convert all or substantially all of the quinapril or acid addition salt to quinapril magnesium.
Stable solid compositions comprising moxeipril magnesium can be made using moexipril or an acid addition salt thereof, by reacting the moxeipril or acid addition salt with an alkaline magnesium compound in the presence of a solvent, so as to convert most or all of the moexipril or acid addition salt to moexipril magnesium.

There is disclosed a stable pharmaceutical solid composition comprising enalapril as the sodium salt, which is made by the steps of: i) mixing enalapril maleate with a carrier, an alkaline sodium compound, and water; ii) drying the wet mass; iii) further processing the resultant dried mass into tablets. When the water is added in the aforesaid process, an acid-base reaction occurs which converts the enalapril maleate into the more stable enalapril sodium salt.
Provided herein are stable enalapril oral liquid formulations. Also provided herein are methods of using enalapril oral liquid formulations for the treatment of certain diseases including hypertension, heart failure and asymptomatic left ventricular dysfunction.
