ABSTRACT:
An amlodipine maleate pharmaceutical composition is provided with good stability when formulated with a pH within the range of 5.5 to 7, when measured as a 20 wt % aqueous slurry. The stability can also be aided by making the pharmaceutical composition from amlodipine maleate particles having an average particle size of greater than 20 microns, preferably greater than 100 microns.
