Biosimilars proving to match regular drugs

At Pharmacy Europe, they look at the results of the biosimilar epoetin zeta, which was tested against epoetin alfa.

The results were as follows:
A study was performed to assess these different product formulations by using and comparing an array of analytical techniques for product characterisation, including reversed-phase high-performance liquid chromatography (RP-HPLC). The RP-HPLC analysis demonstrated that the presence of polysorbate 80 in the formulation of epoetin alfa caused considerable peak interference, with chromatograms of epoetin alfa samples showing greater fragmentation of the main epoetin peak compared with epoetin zeta. The epoetin zeta formulation offers some advantages over epoetin alfa in terms of the drug product analysis performed according to the methods used in this study.

This could be further proof that biosimilars are a viable alternative for patients. Read the full article here.
