| Sumario: | The objective of the present study was to stabilize doxorubicin hydrochloride in sugar-phosphate
amorphous mixtures at ambient temperature by drying it with vacuum foam drying. Finished products
were evaluated for foam characteristic, residual moisture content, reconstitution time, percent drug
recovery and drug-excipient interactions. FTIR studies revealed existence of physical interaction of drug
with sugar. Light microscopy showed formation of amorphous glass which was supported by the observations
of XRPD analyses. The optimized composition in vacuum foam drying was processed by lyophilization
and their stability was compared. Storage at ambient temperature for 6 months showed that stability
of vacuum foam dried product was better than lyophilized products. The amount of residual moisture affected
the stability of drug. The detailed study revealed lactose and sodium dihydrogen phosphate is best
suited for stabilization of doxorubicin hydrochloride at room temperature. |
