Pharmaceutical equivalence of oncology products marketed in Brazil
The aim of this work was to assess pharmaceutical equivalence among medicinal products containing cisplatin, doxorubicin hydrochloride and paclitaxel that are marketed in Brazil by various manufacturers. We analyzed 14 lots of cisplatin injectable solution from 4 manufacturers (Labs B, C, H and I), 15 lots of doxorubicin hydrochloride injectable lyophilized powder from 5 manufacturers (Labs C, F, G, H and J) and 38 lots of paclitaxel injectable solution from 8 manufacturers (Labs A, B, C, D, E, F, G and H). All products complied with the criteria established in the Brazilian and American pharmacopoeias. The assay results for contents of cisplatin, doxorubicin hydrochloride and paclitaxel were 94.3-105.9%, 97.1- 106.6% and 90.2-109.4%, respectively. Statistical analysis showed that the same products from the various manufacturers were equivalent.
