ABSTRACT:
The present invention is directed to ACE inhibitor-containing compositions stabilized by the presence of magnesium oxide. Preferably, the ACE inhibitor, quinapril, is protected from certain forms of degradation when prepared in a pharmaceutical composition consisting essentially of magnesium oxide as the stabilizing agent. The presence of magnesium oxide also lends itself to favorable processing conditions during the manufacture of ACE inhibitor-containing compositions, especially processing by wet granulation.
