Patent ID: 8352283

Claim:
A method comprising: obtaining drug information for each drug of at least two drugs, wherein the drug information comprises at least one of: drug strength, drug effectiveness, dosage frequency, and dosage period; determining, by an equivalent dose calculation module, equivalent doses between a first drug subset and a second drug subset of the at least two drugs by analyzing the drug information for each of the drugs of the at least two drugs, wherein the first drug subset and the second drug subset are equivalent dosage regimes; reviewing current relative purchasing amounts between the first drug subset and the second drug subset; comparing costs between the first drug subset and the second drug subset of the equivalent doses of the at least two drugs, wherein the comparing includes analyzing contractual price adjustments to the costs of the equivalent doses of the drugs based on the current relative purchasing amounts between the first drug subset and the second drug subset; determining, via a processing device, new relative purchasing amounts between the first drug subset and the second drug subset, based on the comparison; and outputting the new relative purchasing amounts.
