eurjchem-884	Tammam, Marwa Hosny	Photostability studies on gemifloxacin and lomefloxacin in bulk powder and dosage forms	2014	8	.pdf	application/pdf	3510	206	54	The rates of photodegradation of GFLX and LFLX were significantly enhanced by the addition of TiO2 (Table 1) in comparison with rates of photodegradation of these drugs in direct photodegradation (without TiO2). Photodegradation process occurred due to the adsorbing of drugs over TiO2 particles and the photodegradation is driven by injecting of an electron from excited state of drug into the conduction band of TiO2 particles which leads to the oxidation of drug molecules, also the electron of conduction band caused by moving the electrons from valence band and these electron may be used to drive another photoreactions of drug molecules in different routes. HPLC LC‐MS/MS Gemifloxacin Lomefloxacin Photostability Fluoroquinolone drugs 1. Introduction Drug photostability constitutes an important current subject of investigation as the photodegradation process can result in a loss of the potency of drug and also may cause adverse effects due to the formation of toxic degradation products [1‐5].	cache/eurjchem-884.pdf	txt/eurjchem-884.txt
