Research of Present Domestic Situation on Off-patent Originals and Generics
Abstract： Objective: In order to understand the general situation of off-patent originals and generics in the domestic market, evidences for quality consistency evaluation for generics and related policies were provided. Methods: Through data reduction and analysis of Shanghai Purchasing Drug Information System (HPDIS), quantity, dosage form distribution and price ratios of generics and their off-patent originals were researched. Results: There are 300 generic names of off-patent originals in the domestic market. Half dosage forms of generics are tablets and capsules, 33% are injections, and the rest own a smaller proportion. The overall price ratio of generics and their off-patent originals in the same year and the same dosage form is about 60%, but there are also some great disparities and price inversions between generics and their off-patent originals. Conclusion: Quality consistency evaluation for generics will have a strong impact on quality, industry, pricing and expenditure of pharmaceuticals, parties concerned should predict and prepare for it.
