[The radioprotective action of suprofen].

Suprofen is a new non-steroidal anti-inflammatory drug administered intragastrically 90 min before roentgen irradiation in a dose of 20 mg/kg and then daily for 10 days in a dose of 10 mg/kg exerts the radioprotective effect evaluated according to a 30-day survival rate and an average life expectancy of the deceased animals as well as according to a decrease of postirradiation leukopenia incidence. A single administration of suprofen following roentgen irradiation exerts no radioprotective effect. Suprofen was found to enhance the radioprotective action of cysteamine.
