“…The maximum tolerated dose with fractionated radiotherapy was 340 mg/ m 2 given 4 days a week for 5 weeks 23 . WR-2721, 200 mg/ m 2 , given in a 5 min intravenous infusion 30 min before 2 Gy x 5 days/ week for 6 weeks induced side effects like nausea, vomiting and hypotension, leading to termination of drug in some patients due to severe hypotension 16 .…”

“…Los primeros ensayos fase I con amifostina e irradiación en USA fueron llevados a cabo por la RTOG 21,22 , estableciendo la dosis máxima tolerable (DMT) de amifostina para radioterapia. Los principales efectos secundarios incluyeron hipotensión, emesis, somnolencia, estornudos, gusto metálico e hipocalcemia; las náuseas y vómitos fueron la toxicidad limitante de dosis (740 mg/m 2 en 15 minutos).…”

“…Cuando la infusión de amifostina no superó los 15 minutos, se observó una disminución significativa en la incidencia de hipotensión, pasando de un 6% a un 24% cuando ésta se prolongó más allá de los 15 minutos; no obstante, la hipotensión desapareció cuando se dejó de administrar amifostina y con la introducción de fluidoterapia. Finalmente, la MDT de amifostina antes de radioterapia fue establecida en 340 mg/m 2 , 4 veces / semana durante 5 semanas, en infusión inferior a 15 minutos 21 .…”

“…TheaminothiolWR-2721 (amifostine; NH 2 -(CH 2 ) 3 -NH-(CH 2 ) 2 -SH 2 P0 3 *1.5H 2 0), which is dephosphorylated in vivo by alkaline phosphatase to yield the corresponding biologically active free sulfhydryl form WR-1065, has emerged as the most promising of the many potential free radical scavengers that have been evaluated as radioprotectors [85]. It appears to accumulate to a greater extent in normal than in tumor tissue, and can react with electrophilic DNAdamaging agents such as cisplatin and cyclophosphamide, thus reducing many of the untoward side effects of these drugs (as well as those of radiation) without reducing therapeutic efficacy [86].…”
