[Fundamental and clinical study on ceftriaxone in the field of obstetrics and gynecology].
It is reported that ceftriaxone (Ro 13-9904, CTRX) has a half-life time of 7 to 8 hours. In the present study, the serum level 18 hours after intravenous injection with 1 g CTRX was as high as 9.3 micrograms/ml while obviously a higher tissue concentration was maintained compared with other drugs. These facts suggest that CTRX is effective against infections and that the dosage and frequency of administration could be reduced. The global evaluation revealed that CTRX was clinically effective in all the 4 cases with infections. As the adverse reaction, light leukopenia was observed only in 1 case out of the present 4 cases and 20 others administered with CTRX.
