1 to 2gm once daily
It produces its action by binding to PBPs (Penicillin binding proteins) ceftriaxone inhibits cell wall synthesis. This inhibits peptidoglycan synthesis in transpeptidase step. It produces bactericidal effect by time dependent killing effect.
After administration it penetrates into body fluids and also achieves levels in cerebrospinal fluid which inhibits most pathogens. This can be administered as both IM/IV
The drug produces dose dependent response, with different rate of absorption. The volume of distribution of ceftriaxone is 5.78 to 13.5 L. It reversibly bound to plasma protein. It can also cross blood brain barrier.
Nearly about 30-67% of the drug is excreted through urine. The drug is also excreted through biliary secretion as microbiologically inactive compound in feces. The elimination half life can be ranged from 5.8 to 8.7 hours
