Claim 0:
1. A composition comprising a stabilized chlorthalidone suspension, the stabilized chlorthalidone suspension, comprising:
chlorthalidone, wherein the chlorthalidone is undissolved in the suspension and wherein the undissolved chlorthalidone is present in the suspension at a concentration of between 1 to 20 mg/mL;
a solubilizing or wetting agent;
at least one suspending agent;
at least one viscosity increasing agent or at least one anti-caking agent; and
water;
wherein the solubilizing or wetting agent, the at least one suspending agent, and the at least one viscosity increasing agent or at least one anti-caking agent are present in respective quantities to provide uniform dispersion of the undissolved chlorthalidone following initial stirring of the suspension so that a first chlorthalidone concentration in a first sample of the composition differs from a second sample in a second volume of the composition by no more than 5% after storage for at least 60 min without stirring.
