-17. (canceled)
A suspension of a proton pump inhibitor consisting essentially of:
- a proton pump inhibitor;
- poloxamer;
- a suspending agent, wherein the suspending agent is (i) sodium carboxymethylcellulose (CMC) or (ii) a combination of sodium CMC and microcrystalline cellulose;
- an acid neutralizing agent;
- a defoamer;
- a preservative;
- water;
- optionally a buffer that maintains a pH of 8 to 9.5;
- and
- optionally one or more selected from a sweetener, a coloring agent, and a flavoring agent;
- wherein the suspension is homogenous and stable for at least 30 days at ambient conditions and at refrigerated temperature conditions.
8 more elements
A kit consisting essentially of:
- a first container having a 100% w/w powder of a proton pump inhibitor (PPI);
- a second container having a liquid diluent consisting essentially of poloxamer,
- a suspending agent, wherein the suspending agent is (i) sodium carboxymethylcellulose (CMC) or (ii) a combination of sodium CMC and microcrystalline cellulose,
- an acid neutralizing agent,
- a defoamer,
- a preservative,
- water,
- optionally a buffer that maintains a pH of 8 to 9.5, and
- optionally one or more selected from a sweetener, a coloring agent, and a flavoring agent;
- wherein the liquid diluent is stable for at least 30 days at 5±3° C. and is resistant to gel formation for at least one freeze-thaw cycle,
- wherein the first and second containers are of a size such that the PPI powder and liquid diluent can be combined in either the first or second container to produce a reconstituted PPI suspension;
- and
- wherein the reconstituted PPI suspension is homogenous and stable for at least 30 days at ambient and refrigerated temperature conditions.
