RT Journal Article SR Electronic T1 Photostabilization of Doxorubicin Hydrochloride with Radioprotective and Photoprotective Agents: Potential Mechanism for Enhancing Chemotherapy during Radiotherapy JF PDA Journal of Pharmaceutical Science and Technology JO PDA J Pharm Sci Technol FD Parenteral Drug Association (PDA) SP 259 OP 261 VO 43 IS 6 A1 Habib, Muhammad J. A1 Asker, Ahmed F. YR 1989 UL http://journal.pda.org/content/43/6/259.abstract AB p-Aminobenzoic acid (PABA), urocanic acid, and sodium urate were found to significantly enhance the photostability of doxorubicin hydrochloride [adriamycin, (ADR)] .dl-Methionine, thiourea, and glycine also increased the photostability of this drug, but to a lesser degree. Sodium thiosulfate on the other hand, was found to be detrimental to the photostability of ADR. The photostabilizing effect of PABA was found to increase with increase of its concentration and was influenced by the pH and the buffer species of the vehicle. The findings would have an impact on the enhancement of therapeutic efficacy of adriamycin when administered during radiation therapy.
