Abstract
BACKGROUND
Albumin-bound paclitaxel (nab-paclitaxel), as a special targeted preparation of paclitaxel, has the advantages of good curative effect and less side effects in anti-tumor therapy. The existence of the plasma-peritoneal barrier and insufficient blood supply make intravenous drugs hard to reach the peritoneum, while hyperthermic intraperitoneal chemotherapy can solve the difficulty. And compared with systemic medications, HIPEC can also give higher concentrations of chemotherapy drugs in the abdominal cavity, while ensuring lower systemic toxicity. However, at present, there is no relevant report on the clinical study of nab-paclitaxel during intraperitoneal hyperthermic chemotherapy, and its stability under special temperature conditions has not been reported either.
METHODS
In this study, We examined three batches of albumin-bound paclitaxel dissolved in saline at different temperatures (25 °C, 37 °C, 41 °C, 42 °C and 43 °C) for the changes of human serum albumin content, human serum albumin polymer content, related substance content, in-vitro release rate, paclitaxel binding rate and paclitaxel content at different temperatures.
RESULTS
Our results demonstrated that the indicators including human serum albumin content, human serum albumin polymer content, in-vitro release rate, paclitaxel binding rate and paclitaxel content were stable to the several temperatures, except that Taxane (0.1%) and other individual impurities in the determination of related substance content fluctuated comparatively widely with the change of temperature. In addition, only Taxane (0.1%) and 7-Epitaxol (1%) were detected.
CONCLUSIONS
Overall, albumin-bound paclitaxel is relatively stable to different temperatures (25 °C, 37 °C, 41 °C, 42 °C and 43 °C). This study will lay a foundation for further studies on the albumin-bound paclitaxel during hyperthermic intraperitoneal chemotherapy.
